France – Kallfass

Bereits die vierte Anlage EN Already the fourth system

With three different sawing lines at the Saint Avit site, Dubot Bois & Scieries cuts 140,000 m3/year - exclusively softwood. One speciality is the cutting of Douglas fir, which accounts for around 50% of the total volume. “When using the three saw lines—from circular saw technology to log band saws—we can process almost all log diameters harvested from the forest”, explains Florian Baudron, the Technical Director at the sawmill. Logs with a diameter of 10 to 100 cm and trunks 2 to 9.5 m long are cut.

Enhanced performance and superior quality

The origins of the company date back to the beginning of the 19th century. The sawmill at the Saint Avit site has existed since 1945. Since then the Dubot family has continuously expanded the plant.

As mentioned at the beginning, Kallfass has been a supplier of sorting and stacking lines for a quarter of a century. Last year, Dubot ordered its fourth system from Kallfass. “Our system behind the circular saw line—also from Kallfass, of course—was becoming outdated. We also only had twelve boxes for sorting, which limited the performance of the saw line. For this reason, we decided to invest in a new sorting and stacking system”, reports Baudron and continues: “We also knew that Kallfass would be able to rebuild the new main product line in place of the old one”. As part of the project, Kallfass also supplied a wane scanner and a trimmer provided by Microtec. Both ensure that Dubot can produce a high quality of sawn timber.

The conversion at Dubot started in June 2024, and the Kallfass system has been in operation since the end of October. In the meantime, Dubot was able to transport the main products — at a slightly reduced capacity — using the existing Kallfass side boards sorting system.

Robust system for main products

The Kallfass delivery starts from the transverse take-off of the main product behind the sawing line. The sorting and stacking system is designed for timber lengths of 2.5 to 7.3 m and a maximum cross-section of 63 x 260 mm. “We have also tested 100 x 260 mm - that also worked without any problems thanks to the robust design”, says Production Manager Guillaume Cedan with a smile. First, the timber is separated.

A Tongloader with a capacity of up to 80 pieces per minute cycles the sawn timber onto an assessment chain conveyor. At this point, the machine manufacturer has incorporated an innovative feature, as Kallfass Managing Director Hans Haist points out during the tour: “Unlike before, when employees activated a button to ensure the timber’s quality or adjusting the wood, we have now provided a touch screen interface. Now, the operator can easily determine the quality”. The assessment chain conveyor facilitates the inspection of both timber faces. This was especially crucial for Dubot, since the sawmill prioritises sawn timber of the highest quality above all else.

Transfer using transport trolleys

The boxes are emptied onto a longitudinal conveyor and the wood is then transferred to a transport trolley. The trolley now travels at a right angle into the new parallel hall and the sawn timber is transferred to the step separator and unscrambler. Subsequently, layers of timber are created and the Kallfass multiple cross-cut saw is called into action. “The latter is equipped with five saw aggregates, four of which can be positioned automatically”, explains Jonathan Bleesz, who represents Kallfass in France with his company VBI. The mechanisation transfers the sawn timber layers to the stacker. Mr Haist estimates the output of the stacker to be up to ten layers per minute. The stacker is equipped with eight single-stack magazines into which the sticks are placed.

The finished sawn timber stacks are transported onto a generously dimensioned cross conveyor. The forklift operator either removes the timber stacks or feeds them to the existing strapping system, which Kallfass has integrated into the control system. “This area is now fully automated; employee involvement is unnecessary, and wood package data transfers automatically to the strapping system," Mr Haist explains.

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.

Neues Sortierwerk überzeugte mit Technik EN New sorting system impressed through technology

After a fire in 2020 at the headquarters in Moussey/FR, the owners of the Lemaire sawmill decided to rebuild the line with a log band saw while investing in a new sawmill for cutting small diameter timber at the La Petite-Raon site a few kilometres away. "This step means we can process the entire log spectrum from the forest", says Managing Director Maxence Lemaire, explaining the move. They bought an industrial site in La Petite-Raon in 2006 which they previously used for sorting logs and operation of a planing unit. Installation of the saw line began two years ago. The sawmill was to be initially housed in the existing hall. However, the Lemaire family eventually decided to erect a new building. The log infeed came from Holtec, the cutting line was supplied by Veisto and Kallfass from Baiersbronn-Klosterreichenbach/DE was chosen for the sorting and stacking plant. "We looked at several providers. Kallfass impressed us both in terms of the technical execution and the expertise of the employees", explained Lemaire, adding that "Kallfass is also active in further processing and has already supplied us with a bundling system for the planing line". Kallfass handled the project with its French representative, VBI from Barr/FR.

Main and side products via a single line

The first log passed over the new saw line, which processes logs up to 55 cm in diameter, in September 2022. Larger dimensions are sent to the large diameter timber mill in Moussey. "Our goal is to cut 300,000 solid cubic metres per annum at both locations in the future. About 20 % of the volume involves large diameter timber", explains the Managing Director. All the main and side products produced on the new chipper line are conveyed separately on two decks to the Kallfass system. "The sorting and stacking system is designed for an output of up to 140 cycles per minute, lengths of 2 to 6.2 m and cross sections up to a maximum of 100 by 250 mm", relates Kallfass Managing Director Hans Haist.

New type of flexible alignment

The timber is conveyed via a transverse buffer conveyor and a separation station to an assessment station where an employee checks the material and pulls the pieces forward for a subsequent trimming if necessary. The boards and squared timber then pass through a Goldeneye 900 scanner from Microtec. This determines the quality and dimension, transmitting the data on to the subsequent Kallfass trimmer. Kallfass installed a novelty between the Goldeneye and trimmer: a flexible alignment. "This can adjust the boards - depending on the scan result - by up to 300 mm with centimetre precision. This means that shorter cuts can also be made on the end faces, ultimately increasing the yield", explains Haist. The trimmer is equipped with 13 saws. The timber is then divided into 71 sorting boxes.

After the boxes have been emptied, the wood is fed to another employee for a follow-up check via a step feeder and separator. Following the creation of layers, the timber pass through the tried and trusted multiple circular cross-cut saw from Kallfass. This saw is equipped with four sawing units, three of which are completely automated and can be positioned as required. Remaining pieces are discharged via a waste belt in the direction of the Vecoplan disposal unit. "The downstream stacking line has a capacity of up to 14 layers per minute and is equipped with six double magazines for stacking", elaborates Jonathan Bleesz from VBI. The finished packages, which are mainly 600 mm high, are sent to the Fromm strapping unit. Kallfass supplied a squared timber milling machine for this purpose. As mentioned at the beginning, the Kallfass plant sorts main and side products. However, space for another side product sorting unit was already taken into consideration in the conceptual design.

Lemaire is convinced that investing in the new sawmill was the right step: "We have already been able to win four large customers who previously imported sawn timber. Now we can generate added value domestically".

Ausbau des Sortierwerks EN Expansion of the sorting system

The family-run Bois Du Dauphine is located in the Alpine region between Grenoble and Chambéry, France. Founded in 1983, the company was originally a forestry operation. In the meantime, a timber industry has developed in Le Cheylas, France: B.D.D. operates a sawmill, and the neighbouring sister company A.E.B. produces pellets, heat, and electricity. In keeping with the saying, “stagnation is regression”, those people responsible have devised a sensible investment strategy for 2022 to 2024. The objectives are clearly defined:

Increase in cutting capacity by approx. 25 %
Improving the yield by 3 % based on more accurate defect detection, precise cuts, and sorting in several boxes when the length is distributed from 2.5 to 6 m in 50 cm increments
Additional increase in yield to be achieved by doubling the number of side products
Increasing the capacity in the pellet plant and stabilising power generation in the winter season

New sorting system in operation

In September of 2022, B.D.D. was able to complete one of these investment steps: Kallfass, Baiersbronn, Germany, installed and expanded the sorting system, including the wood package and strapping system.

First, Microtec installed at B.D.D. a Goldeneye scanner to replace an existing one. When using the downstream trimmer saw, which was subsequently installed by Kallfass, undesirable wood features can be effectively removed. Thereafter, the sorting takes place: In the past, B.D.D. separated all sawn timber (main and side products) using 25 sorting boxes. In order to expand the system, Kallfass added 50 more inclined boxes. According to Kallfass, the charging system can output 160 pieces per minute. The board cross-sections range from 12 x 60 mm to 100 x 250 mm, whilst the lengths vary from 2.4 to 6 m.

The boxes are emptied downwards onto a long buffer chain conveyor. After the boards have been separated, they pass in layers through a multiple cross-cut saw with seven saw aggregates.

Flexible stacking

Subsequently, the boards are transferred to the stacking unit, where 16 layers per minute can be produced. B.D.D. opted for the Kallfass stick placement system, which comprises seven adjustable double magazines. This design allows thin sticks (14 x 25 mm)—that were previously intended to be disposed of—or thicker kiln sticks (25 x 50 mm) to be used.

“Now, this system allows us to produce different packages”, explains Bertrand Jurdic, Technical Manager at B.D.D. The package sizes range in width, height and length from 1,000 x 450 x 900 mm to 1,200 x 1,400 x 6,000 mm.

The finished packages enter a swivelling package discharge system, which changes from the transverse to the longitudinal direction. The strapping station, made by Fromm System GmbH, is supported by a layer of squared timber. In addition, Kallfass will supply an extended aligning roller conveyor, thus increasing the buffer area.

Little downtime

Kallfass completed the modification effort in the summer, requiring about three and a half months. “We only required three weeks of downtime for the saw line during this time, in order to connect the new sorting system to the existing plant from 2010”, Jurdic explained. Kallfass delivered the steel and mechanical parts for the project using 13 lorries. B.D.D. decided to use a wooden construction method for the new hall.

The entire preliminary discussions, consultation, development, and handling of the project were organised by Hans Haist, Managing Director of Kallfass when he interacted with Jonathan Bleesz of VBI (Kallfass' representative in France). “When we expanded the sorting system, we were able to achieve an important step in our expansion plans”, says Jurdic.

Palettenbretter exakt
stapeln und paketieren EN Precision stacking and packing of pallet boards

CBD Bois currently cuts around 100,000 solid cubic metres per annum at its main facility in Craponne-sur-Arzon on two saw lines (for large and small-diameter logs respectively) and at their ETS RAZ mill. The latter is located around 15 km away in Dore-l'Église and was acquired in 2016. CBD Bois mainly processes fir and Douglas fir, with logs being obtained within a radius of approximately 100 km. Construction timber is cut in Craponne-sur-Arzon on the large-diameter log line using a block band saw and band resaw. A used Kallfass stacking system is employed behind this. “We’re so satisfied with this system from Kallfass that we decided to also engage them to address stacking of pallet products behind the small-diameter log line”, says Plant Manager Magali Castillon. As cutting has increased enormously since 2018 and stacking was previously a manual process performed by four employees, CBD Bois saw that action needed to be taken. The new cutting, stacking and packing line from Kallfass has been in operation since January 2021. Kallfass handled the project through VBI, its French representative in Barr, France.

New customers gained through a high level of accuracy

“We can now operate this part of the line with only one employee”, notes an evidently pleased Magali Castillon. “We’ve also gained new customers, as our pallet products are now cut and stacked with millimetre precision. This is an important quality feature. We can also process as much as 30 % more timber with this line”.

The Kallfass system is designed for infeed lengths of 2.2 to maximum 4 m. The width can be set between 70 and 300 mm, and the maximum thickness is 100 mm. “The smallest cross section that the system can process is 60 by 15 mm”, explains Jonathan Bleesz from VBI. Main and side products are drawn transversely to the left behind the small diameter line, with the main products landing on the upper buffer deck and side products on the lower. “The timbers are then fed to the stacking system, depending on the filling quantity, as each deck can accommodate sawn timber for around one to two packages”, explains Kallfass Director Hans Haist. An employee also has the opportunity to examine the workpieces after separation. Any poor products can then be ejected, if necessary, in this area. These are then conveyed to the woodchipper via a vibrating conveyor.

Following the creation of layers, the timber is conveyed through the multiple cross-cut saw. This is equipped with four saw aggregates, namely one zero saw and three variable saws. This means that up to three boards can be created, depending on the infeed length. The cut lengths are then transferred to the packing and stacking system which can create 14 layers a minute. An employee currently lays the stacking sticks manually, but Kallfass has already made preparations for retrofitting an automatic stick placement system. Chains stabilise the position from above during transferring. The completed packages have a length of 0.8 to 4 m and a width of 1 to 1.2 m. The Kallfass system can also create sandwich packages, primarily to facilitate handling of short stacks. The first and last layers consist of continuous boards in this context, with short pieces placed in between. The completed packages are conveyed via a hoisting unit for strapping with squared timber.

“We’re more than satisfied with the way Kallfass and VBI have handled this, particularly with regard to the service involved”, concludes Magali Castillon.

Produktion verdoppelt EN Production has been doubled

Claude Schnepf, Managing Director of SCS, employs 70 personnel, 40 of which are working directly at the sawmill in the Alsatian commune of Steinbourg/FR. SCS generates an annual turnover of € 22 million. Schnepf’s goal is to reach € 30 million per annum, which is why he decided to double the capacity of his existing plant. Construction of the plant and conversion of the premises cost around € 10 million.

Scierie et Caisserie de Steinbourg (SCS) is one of the largest beech wood sawmills in France. It began life as a sawline consisting of a log bandsaw from the French manufacturer Rennepont, a Techrnan mechanization system and a trimmer. There was no automated sorting system. The beech wood is dried and dampened (steamed) using twelve fresh air/exhaust air dryers from Mühlböck, and there are plans to add a further five. The original line produced 50,000 m³ p.a. of high-quality beech timber for furniture manufacture, squared timber and wood for pallet production. 80 % of products are exported to China, Asia, the Levant region, Spain, Italy and Germany. A number of reasons led Claude Schnepf to choose Kallfass as a partner for this major project.

The two most important were the geographical proximity (the Kallfass plant is only about 100km away) and linguistic commonality. “Kallfass played a leading role in the planning and realisation of my new sawline, and our cooperation worked perfectly”, stressed Claude Schnepf.

The project was completed at an impressive speed. The planning phase started in autumn 2016, with the new line commencing operation in the summer of 2018.

Doubling capacity

The new line consists of a Primultini log bandsaw, with the mechanization, sorting and stacking systems being supplied by Kallfass. The trimmer was provided by EWD, with a multi-blade circular saw being supplied by Primultini.

The part of the plant provided by Kallfass commences downstream of the EWD trimmer. The trimmed timber is conveyed through the contactless measurement system by a cross conveyor. The dimension measurement system from Kallfass measures the thickness and width using a laser/encoder and length with a safety light barrier. Quality is assessed with the aid of chalk markings and luminescence sensors. The beech timber is then classified in thirteen levels. The customer can individualise sorting as required.

Simplified variation options

When a box is filled, it is forwarded automatically to the packet assembly station, with stacking selectively possible using wooden or aluminium battens. The batten magazine is equipped with an automatic stick placement system. The completed packets can be collected by a forklift truck through a packet discharge on the outer wall.

“We configured the entire Kallfass plant with great care to avoid any damage to the high-quality timber involved”, explains Hans Haist, CEO of Kallfass.

Everything for pallets

Timber that does not meet quality criteria for furniture manufacture (e.g. squared timber with red heartwood) is cut to the desired length on a separate line using the Kallfass CNC crosscutting saw. The CNC crosscutting saw has four chop saws, enabling cutting of square timber with millimetre accuracy. Crosscut lengths ranging from 800 to maximum 3200 mm can be achieved. The capped square timbers are automatically forwarded downstream to the multi-blade circular saw for separation.

Training for employees

The second complete sawline has enabled SCS to double its capacity. Full exploitation of the machinery is only possible with training of additional personnel. Four employees working in two-shift operation are currently responsible for two band saws.

At least one additional machine is planned. Four employees are also working on the trimmer, with another worker currently undergoing training. “This completely new increase in production capacity is of little use to me without competent machine operators. We’re trying to give our current workers effective instruction while training new personnel to assist us”, adds Claude Schnepf.

Enhanced performance and superior quality

Kallfass has now delivered the fourth system to Dubot. Shown in the picture: Guillaume Cedan and Florian Baudron from Dubot with Kallfass Managing Director Hans Haist and representative Jonathan Bleesz (from left)
