Den Output verdreifachen EN Tripling the output

This is the target the French sawmill Blanc has committed itself to. Located in the Rhône-Alpes region in the south-east of the country, the family-run company is relying almost exclusively on German engineering technology for its ambitious project. Kallfass accounts for an elementary component of the extensive investment. The machine builders from Baden-Württemberg were commissioned to construct a flexible and versatile sorting system that is specially tailored to the needs of the French market and ensures Blanc's long-term competitiveness.

Strengthen market presence

In 2023, the sawmill was still cutting approx. 45,000 cubic metres per year. The aim is to break the 100,000 cubic metre mark as early as next year, more than doubling the output. The wood, mainly spruce, fir and Douglas fir, is sourced from the mountainous region of the Rhônes Alps and bordering with France, Switzerland and Italy. According to Blanc, the company has no supply problems to contend with and is also confident about the future in terms of sales: “We have already acquired a number of new customers who previously sourced their products from Scandinavian producers. We can deliver products of equal quality. We compensate for any price disadvantages with short delivery times and the possibility of local value adding,” explains Blanc.
The family-run company has always produced building products that are sold to value added wood manufacturing industries and, above all, timber construction companies. “We sell exclusively in France. In addition to our high quality, our customers particularly appreciate our versatility,” reports the company successor.
Board dimensions of 75 to 250 mm in width and 18 to 100 mm in thickness can be processed on the Kallfass system. “Almost everything that the French timber construction industry needs,” summarises Blanc. “The focus here is on building with wood. We are also noticing this in the increasing demand for our products. However, in order to further promote timber construction, producers must also be able to deliver.”

Successful general remodelling

To meet our objectives, construction of a new long-wood plant at the logyard started in 2022. Updates to the sawing line, edging system and scrap wood removal. As with the other machines, Blanc relies on an established German supplier, Kallfass, for the sorting system. “Only Kallfass could supply us with a system that combines flexibility and performance so efficiently. This offers the perfect balance of price and performance.,” says senior partner Frédéric Blanc, impressed by the Baden-Württemberg mechanical engineering company.

In November 2023, Kallfass finally began delivering the first components. Despite the comparatively large amount of conversion work required, the new sorting plant was able to go into operation in September of this year. “The existing hall had to be extended in both width and height for the new sorting system. With 79 boxes, our system at the Blanc sawmill is now the largest of its kind in France. However, it would not have been possible to manage the varied Blancs ranges otherwise,” says Jonathan Bleesz, Kallfass’ sales partner in France, giving an insight into the project.

Focus on versatility

The new system is 130 metres long and has two levels in order to be able to meet the customer's request for 79 vertical boxes. “The variety of dimensions is typical for French sawmills of this size. The market is looking for producers who can offer everything,” reports Bleesz, who has been working with Kallfass for over 15 years and is therefore very familiar with the special features of the French market.

Kallfass receives the sawn softwood from the sawmill via a double unscrambler, which transports the material to the higher assessment level in a first step. A curved chain conveyor moves the building products via the Tongloader to an assessment station for separation. Here, the trained eye of the operator determines the quality of the cut product. Up to six different qualities can be added to the wood at the touch of a button. “The system currently runs at approx. 80 cycles per minute - more would not be possible with a visual assessment. If a scanner is retrofitted, we can increase this to up to 120 cycles per minute - in terms of mechanical engineering, all precautions have been taken,” reports Bleesz.

After the quality assessment, the boards are transported one level further down via a level changer. The trimmer installed there has ten saw aggregates and can therefore react precisely to the quality assessment specifications. Once the filling volume of a box has been reached, it is emptied onto a chain conveyor and the timber is aligned and separated using a step separator. An operator monitors the layer creation before the sawn timber is sawn to the desired lengths on the multiple cross-cut saw and stacked into finished wood packages on the stacking system. The stacking system was equipped with automatically positionable double strip magazines in order to be able to flexibly place drying or transport sticks. With up to 14 layers per minute, the stacking system has also already been designed for Blanc's future increased production. “The aim was to build a sorting plant that would secure the company's long-term future. This also includes a significant increase in the current cutting performance,” confirms Bleesz.

It's not over by a long shot

Blanc is convinced that the right decision in choosing Kallfass as its supplier was made. In the future, however, the wood will not be loaded directly from the stacking system onto customers’ lorries, but the wood will be processed internally. “First, we need to get the sawmill operating at full capacity and make a few minor adjustments. In the future, however, we also want to refine our products ourselves and are therefore planning the possible construction of a glulam production facility. The first step has already been taken with the expansion of the sawmill’s capacity,” says Quentin Blanc confidently.

Weichen für die Zukunft erfolgreich gestellt EN Successfully setting the course for the future

The core values of Eurolegnami di Debortoli Fabrizio were established when the company was founded, more than 30 years ago. More than 2.5 million pallets leave the plant in Novaledo near Trento in northern Italy every year, destined for industrial customers in the surrounding regions and beyond. Fabrizio Debortoli, Managing Director, emphasizes the need for diversification beyond pallet production to ensure long-term competitiveness. Ultimately, the company's sawn timber supply is crucial to its overall success.

A fresh start

A few years ago, the next generation finally joined the family business. At the same time, the band sawmill's outdated systems were causing production delays, making significant investment in upgrades a necessity. Instead of a costly renovation, however, the decision was made to build a new building on a neighbouring industrial site. Eurolegnami was able to launch production at the new facility at the middle of the year. The company's 100,000 cubic meter annual capacity ensures they can fully supply their own pallet production while also being flexible to respond to market fluctuations in the sawn timber market.

Wood quality, a continuous challenge

Eurolegnami, as a pallet manufacturer, must buy all sawable roundwood assortments. Aside from the cut itself, fluctuating log quality poses a major problem for the sorting process and for handling the sawn timber as a whole. “We needed top-notch professionals in this area and Kallfass quickly stood out. Right from the start, they understood our situation, the requests and objectives of the new plant, and consequently came up with a suitable concept for us that more than met our expectations,” says Nadia Longhi, Administrative Manager at Eurolegnami, pleased to have made the right decision in selecting the perfect supplier for the new sawmill.

“Systems like those of Eurolegnami are part of our proven standard repertoire. This order is particularly satisfying because it establishes another significant reference point for us in the Trentino-Alto Adige region after several years.” says Kallfass Managing Director Hans Haist, speaking at a meeting in Novaledo.

Established concept

Kallfass takes responsibility for delivering both primary and side products from the sawing line onwards. After appropriate buffer solutions, the boards are separated at the first evaluation station. The operator can highlight the quality of wood parts by using a chalk line, and by pulling the wood forward any defective areas can be cut off subsequently using the zero saw. Next, six lasers scan the board, measuring its dimensions. Based on these measurements, each piece of wood is sorted into one of 25 designated boxes. Due to space limitations, Eurolegnami chose a vertical design of these boxes. “In the case of slanted boxes, we could have created a maximum of 20 boxes. However, using smaller pallet dimensions, there is no need to worry about damage, even if using a vertical design,” emphasises Haist during the guided tour.

Once a box is full, it is emptied and the boards are automatically separated using a step conveyor. An operator monitors the layer creation before each board is cut to the desired length on the multiple cross-cut saw from Kallfass. To maximize raw material efficiency in pallet production, Kallfass has integrated seven movable saw aggregates into the system. Haist points out that “In the pallet business, the yield of the raw material is crucial”. “Our focus is on precise, millimeter-accurate cutting to ensure the downstream pallet line receives exactly what it needs.” The boards vary in length, measuring between 600 mm and 5.2 m.

Once cut to size, the timber can either be stacked on the stacking system in an offset position or prepared for transport ready strapped, depending on the application. “Our stacking system has been reliable for years and, like the rest of the system, is remarkably user-friendly, making maintenance and operation straightforward. Depending on the workload, only two to three employees are needed on the line - the rest runs itself,” explains Haist.

Great customer confidence

The order situation at Kallfass remains good. “Some of our books are already well filled until 2026. The orders vary in scope, from minor modifications and updates to complete systems and large-scale projects. We are particularly pleased to have been able to once again demonstrate our pallet expertise in this project, enhancing Eurolegnami's preparedness for the future,” stated Haist with satisfaction.

Eurolegnami is pleased with the results of the project. “We were able to visit several sawmills in Germany at the beginning of the decision-making process. Today, we understand the reasons behind the significant customer loyalty to Kallfass,” explains Michele Debortoli, successor and junior manager.

Perfekt gekappt und gestapelt für Palettenfertigung EN Perfectly cut and stacked for pallet production

Bottleneck eliminated

Until now, Rückerl has used two cross-cut saws to cut the wood for pallet production. "That was very time-consuming and no longer in keeping with the times. In addition, cutting to size became a bottleneck due to the increasing quantities. Furthermore, high dimensional accuracy was no longer guaranteed due to the automation of pallet production. And it is becoming increasingly difficult to buy fixed lengths on the market,” explains Marc Rückerl, who manages the company together with his brother Roman. Thus, a new cutting solution had to be found. "We looked at various providers. We liked the quality of the Kallfass solutions right from the start,” reports Roman Rückerl.

In addition, the proximity to Kallfass in Baiersbronn-Klosterreichenbach spoke in favour of the Baden-Württemberg supplier. Moreover, communication with Kallfass project manager Matthias Link was very good right from the start, as the two confirm. Kallfass supplied Holzwerke Rückerl with a cutting and stacking system, which has been in operation since March.

Flexible system for high performance

Rückerl's typical approach is to purchase sawn timber directly from local sawmills. The new Kallfass line is designed for lengths from 2.5 to 5.1 metres. The wood dimensions for pallet production range from 17 to 22 mm thick and 75 to 150 mm wide. "We usually use the system to cut the raw materials for the Euro pallets. However, its design is very flexible and allows us to process squared timber up to 80 x 80 mm as well," reports Roman Rückerl. The system's target output is around 400 m³ per shift. The sawn timber is separated in layers using a tilt destacking system for double wood packages with automatic stick removal. The boards are fed onto a chain conveyor and then to the operator station using an unscrambler and an alignment roller conveyor. "We deliberately decided against a step separator here because it slows down the system,” says Marc Rückerl. Kallfass installed a thickness monitoring system immediately after the operating station. "If two boards are lying on top of each other, the system stops automatically and the employee can separate the timbers manually," explains the Kallfass project manager.

After the layers are created, the boards are cut to the finished size using the Kallfass multiple cross-cut saw. "This saw is equipped with five saw aggregates; four of which can be positioned automatically," explains Link. The next step is the stacker, which is designed for an output of at least 13 layers per minute and is equipped with ten stick magazines. What makes it unique: To facilitate internal logistics, the boards, which are cut to the exact length required, are stacked directly onto pallets. To achieve this, Kallfass implemented an automatic pallet feed from a magazine. An employee uses a forklift truck to place the required pallets on a roller conveyor. The stacks are precisely aligned and fed to the empty pallet magazine. Subsequently, the magazine feeds the hoisting unit of the stacking system with the pallets and positions them so that the boards are stacked exactly in the centre depending on the length of the parts. To ensure adequate time for collecting the wood packages, there is a generously sized buffer roller aisle at the outlet. Apart from the forklift operator, only one employee is responsible for the entire cutting process.

Flexible Sortierlösung für KMU-Sägewerk EN Flexible sorting solution for SME sawmill

With a cutting capacity of around 25,000 cubic metres per year, the Wolf sawmill is a classic small and medium-sized enterprise (SME). The company's history dates back to 1870. Today, Christian Wolf runs the firm in cooperation with his mother, Gabriele Wolf, and represents the fifth generation of the family-run company. When using a gang saw and a small profiling system, and a downstream circular edger saw, the production of solid structural timber (KVH® for short), glued-laminated timber (GLT) lamellas, packaging squared timber, side products or raw goods from sawn timber (rough planer) is relatively easy. The classification and stacking of the diverse assortments were previously carried out using a simple length sorting system. In this case, employees subsequently stacked the sawn timber manually. “It was too labour-intensive and we find it very difficult to recruit staff. In addition, this sorting has significantly limited our performance,” explains Wolf. In order to become faster and more flexible, a new solution was needed.

Perfect handling

Wolf Jr. looked at several suppliers. Ultimately, he liked the concept of Kallfass, Baiersbronn-Klosterreichenbach, Germany, the best: “Kallfass has always built very reliable sorting systems and was able to complete the project in a very short time. I particularly liked the agility in the planning – all of our requests and ideas were implemented promptly and the new sorting system is specially adapted to the size of our sawmill,” explains Wolf. The renovation work was carried out last year, and the new Kallfass sorting and stacking system has been in operation at the Wolf sawmill since March. “The entire commissioning process went absolutely smoothly. The Kallfass technicians were excellent, as were the programmers," says Wolf, full of praise for the mechanisation specialist's handling. “We now have countless possibilities to deal with our qualities and dimensions.

Kallfass supplied the complete sorting and stacking system, from the transfer downstream of the trimming and circular resaw. The latter is designed for lengths of 1 to 5.1 m and a maximum cross-section of 140 x 180 mm. A conveyor belt transports the squared timber or the main product and boards to two separate buffer decks, which are positioned directly underneath the boxes. “The buffers are dimensioned in such a way that an entire sawmill production output of three to four hours of, for example squared timber, will find space,” explains Kallfass project manager Matthias Link.

After separation, the goods go to the assessment station. The employee can set a back cut of up to 50 cm at the zero line by dragging. If a cross cut is to be made on the opposite side of the wood, the wood is marked with a luminescent chalk. The cross-cut is done later, immediately before stacking. There is also a turning device in the area of the assessment station so that even heavy pieces of wood can be qualified on all four sides. Any unsuitable pieces of wood can be separated into planks and squared timber and ejected into two stanchions immediately after cutting.

“Only one assortment goes directly into the stacking system at a time,” reports Wolf. After the cross-cut station, the remainder is fed upwards to the box sorting system via a level changer. After several discussions, Wolf finally decided on 30 boxes. This means that the space has been used in the best possible way. The boxes are emptied downwards onto a chain conveyor above the buffer decks. The wood then takes the same route as the unsorted goods towards the stacking system.

In order to be able to produce short lengths with millimetre precision, Kallfass installed the proven multiple cross-cut saw. The latter is equipped with four saw aggregates, three of which can be positioned automatically. In order to be able to respond to even more flexible to customer requirements, Wolf is already considering retrofitting a fifth saw aggregate. After layer creation, stacking forks transfer the lumber to the stacking system, which is equipped with four double magazines for drying and dispatch sticks. Finally, a conveyor unit supplies the sawn wood packages. While still in the planning process, Kallfass has already anticipated the possibility of conveniently retrofitting a strapping system.

In order to be able to re-sort dry packages, there is an external infeed. Here, the wood is separated layer by layer using a chain conveyor, which then transports the timber towards the assessment station. The sticks are carried via a conveyor belt into stanchions and removed.

Gebündelter Erfolg EN Bundled success

"It's impossible to put specific figures to the breadth of our product range. We produce what the customer orders", explains Carlo Brever, Managing Director at Bois Brever, in an interview with Holzkurier. "The diversity of products also increases the demands on the machine manufacturer, as their system needs to be able to handle all dimensions. Kallfass convinced us that they were the right people for the job and looking back, we can confirm that they were right."

The Bois Brever sawmill is located not far from the Belgian border, in the north of Luxembourg. With an annual cutting capacity of 50,000 cubic metres, this is already the country's largest sawmill by far. "To be able to survive alongside the large timber industries from Germany, Belgium and France, you have to find your niche and define yourself through quality", reports Brever, who runs the family business together with his daughter, Corinne.

Focus on making work easier

The firm has been a Kallfass customer in Luxembourg for over 20 years. "The partnership and relationship with Brever have always been excellent over the many years we have been working together. As a machine manufacturer, we value these types of customers particularly highly", reflects Enrico Goldhahn, Operations Manager at Kallfass in Wernigerode, Germany, referring to their positive and long-standing relationship with Brever.

After more than 20 years of continuous use, it was finally time to replace the stacking and bundling system in 2023. The aim was not to significantly increase output, however. For Brever, it was important to reduce labour costs and at the same time make the day-to-day work of what would now be the sole machine operator much easier.

"Automation is also a very important issue for small and medium-sized enterprises, and one that should not be ignored under any circumstances. With the new Kallfass system, we have modernised another key area of production. An investment that also increases our appeal in the labour market", explains Corinne Brever.

A lot of machines in a small space

In addition to timber construction and since 2017, solid structural timber, Brever primarily serves the outdoor sector and produces made-to-order planed timber. Boards, mouldings and profiled timber necessitate one thing above all: the need to handle small-scale products in production. "I don't know of any system in our company that has been designed for so many products. An exciting challenge for mechanising the individual work processes", explains Goldhahn.

However, product diversity was not the only challenge that the German machine manufacturer had to overcome. All work steps, starting with the downstream separation of the planing system through to the final stacking of the packages, had to be realised over a maximum possible total length of just 18 metres. "We had to economise on space and buffer paths wherever possible without losing continuous production flow", says Goldhahn, referring to the spatial constraints. For this reason, Kallfass also installed a vertical ascending conveyor at the start of the line: "We need the height to be able to re-stack the timber later on. Due to the specified hall width, we had to use an ascending conveyor based on the paternoster principle", reports Goldhahn.

The next step is for a worker to visually check the quality of the timber. Damaged goods, or broken items in the case of thin mouldings, drop directly into a disposal chute.

Fully automatic bundling

This is followed by the centrepiece of the system, in which, according to Kallfass, "a great deal of experience and expertise has been gained over many years". Boards and mouldings are stacked fully automatically into small packages by the bundler, then strapped with precision to form compact timber packages. The system's capacity is designed for up to ten bundles of wood per minute. "Without bundling, it would not be possible to handle these large quantities of small goods", explains Brever. The advantages of bundling are also immediately apparent on the multiple cross-cut saw, as the ends of several pieces of timber can be cut at the same time. Immediately following the saw, Kallfass came up with a very special feature that absolutely had to be integrated into the system at the customer's request, and that represents Brever's high level of product diversity and individuality. "We have had a major customer for face-profiled planed products for many years", explains Brever, and Goldhahn adds: "To support this, we installed two milling heads after the multiple cross-cut saw, which also permit machining on the face side. The challenge here clearly lies in the degree of precision. The timber must be guided to the milling head with an accuracy of one tenth". After custom processing, the individual boards and mouldings are lastly stacked and transported to a strapping station via a cross conveyor before being transported to the warehouse ready for dispatch.

Ein BSP-Werk für Profis EN A CLT plant for professionals

Exceptional overall concept sets new standards

Log in, finished CLT element out - and all without a forklift. This is how you could describe best wood Schneider's extremely ambitious Greenfield project in just a few words. At the newly founded site in Meßkirch, Germany, the company is implementing a trend-setting, end-to-end production line. Currently the CLT plant is being commissioned. The planned output in the sawmill is 350,000 cubic meters/year. After the final expansion, the CLT production will reach an output of 100,000 m³/year. As in the sawmill, Kallfass also plays a leading role in further processing.

Actually, best wood Schneider “only” wanted to build a cross laminated timber plant at the new Meßkirch site. “Large-format CLT was the only product that we still lacked as a complete supplier for our approximately 5,000 active timber construction customers”, reports Managing Director Ferdinand Schneider during the Holzkurier visit. In addition to solid structural timber (KVH), glulam, glued laminated timber and box girder elements, the family-owned company offers its customers numerous wood fibre insulation systems as well as comprehensive planning and consulting services.

“But then we decided to do it right from the logs and to realise a continuous line from the logs to the finished timber construction products”, says Schneider, describing the process that began seven years ago with the planning phase and continues to this day. According to Kallfass Project Manager Stefan Günther, this constant development and improvement of ongoing projects, both large and small, is characteristic of the company: “Schneider projects are organic and continue to grow. However, these further developments are always constructive, with the best solution coming out on top, regardless of who it comes from”.

The basic idea for Meßkirch was as follows: to implement a continuously automated material flow–from the log feed to the finished and glazed CLT and box elements for walls and ceilings–completely without forklift traffic and almost without manual intervention.

Well-established team

While the sawmill is already rapidly approaching full-load operation, the first expansion stage of the CLT plant is in the middle of the commissioning process. As in the sawmill, Kallfass is responsible for the majority of the mechanisation, the cross laminated timber press and numerous detailed solutions. “In addition, Kallfass, as our vendor of choice, had the planning authority”, adds Schneider, who has already successfully completed numerous projects with the Black Forest system specialists.

Conveyor belts provide the transfer between the sawmill and processing steps down the line. Subsequently, the dried and sorted goods are transported to a Microtec Optiside cup scanner, where the timber is turned to the correct side, if required. In the next processing step, the planer infeed, also from Kallfass, accelerates the goods up to 250 m/min before they are levelled and scanned, and defects are marked. The timber is then packaged in a crosswise offset, strapped if necessary, and fed on roller conveyors to a high-bay warehouse with 1,450 storage locations.

Precise production

For cross-laminated timber production, the pre-planed raw material from the high-bay warehouse is transferred to a finger-jointing line and then to a longitudinal press. Here, white glue or hot melt is used to create an assembly joint. A vacuum lifter removes the assembly joints and transfers them to another part of the Kallfass system.

Whilst the longitudinal layers are directly used to lay a dry press cake in reverse order, cross-layer segments are produced from some of the single-layer boards. “As the longitudinal layer press always produces exactly a multiple of the desired cross-layer length plus kerf, our cross-layer saw does not produce any waste”, emphasises Günther, adding that particular attention is paid to precision when formatting the individual layers and when subsequently arranging the cross-layers and laying the boards. “This means that the panel no longer has to be formatted with a saw after pressing, which saves us time and, above all, material," emphasises Schneider, who runs his panels through a sanding system, a cross-cut saw and a multi-spindle processing machine for the production of any profiles between the press and the joinery systems.

Ingenious details

When laying the dry cake in reverse order, the single-layer boards are sprayed with water on both sides for the upcoming glue application before they are placed in the actual laying station. Apart from the adhesive application system from Oest, Kallfass is also responsible for the entire plant construction, including the subsequent cross laminated timber press. The latter can hold elements measuring up to 3.6 x 16 m and a maximum thickness of 360 mm.

Once the boards have been pressed, sanded and profiled, they move on to one of Technowood's joinery lines, where Kallfass also carries out the mechanisation upstream and downstream of the machines. This includes a specially developed panel turner for CLT, which enables the elements–which may weigh several tonnes–to be turned quickly and safely.

“This means that Kallfass is responsible for the end-to-end material flow–from sorting in the sawmill to the finished panel–and I have to say that all the parts they have implemented run flawlessly”. Schneider praises the installation and the Kallfass team.

Still a lot to do

While the existing line at Schneider is designed for the production of large-format wall and ceiling elements in non-visible quality, the second line will eject elements in visible quality including glaze. Commissioning is scheduled for the coming winter. As a third expansion stage, the Managing Director mentions a production facility for hollow box and rib elements, as used in roof and ceiling constructions, which Schneider summarises under the “Box” product line. This means that the company will have numerous other essential products in its portfolio for its customers.

Schneider describes the planning and implementation of a cross-laminated timber line as extremely complex, whereby he believes there is no ideal solution: “Depending on the objectives and framework conditions, each new CLT plant is always a path of the best compromises, which we realise together with Kallfass in the best possible way”.
