EUROBOIS 2024 knackt Messerekord EN EUROBOIS 2024
breaks trade fair record

With 29,363 visitors and 523 exhibitors, this year's EUROBOIS broke all records, according to the official statement from the trade fair organisation. Kallfass and their French sales partner V.B.I SARL Bleesz International were also pleased with the large number of visitors to the joint stand in Hall 5.

EUROBOIS in Lyon took place in February this year. From 3 to 6 February, the fair opened its doors to the wood industry's experts. From log cutting to sawn timber processing and interior woodworking, visitors were able to find out more at the stands of numerous exhibitors, including some international companies, which held a 31 % share. Fortunately, the statistics show an increase in visitor activity in all areas. Eurexpo quotes figures of +77.83 % in interior woodworking, +114.18 % in frame construction and +41.37 % in sawing and sorting.

France is important export market
Kallfass has also experienced the increased interest in sawing and sorting systems. For the mechanisation specialist and manufacturer of multiple cross-cut saws, sorting and stacking systems, the French market with its many family-operated sawmills is an important export market. In the last three years alone, nine extensive projects have been realised in France, including several sorting systems as well as complex cutting, stacking and packaging systems. Three further projects are in development. The French sawmill operators appreciate the high precision of the Kallfass systems and our ability to design an optimal mechanisation solution for the respective production situation.

In V.B.I Bleesz, which is celebrating its 20th anniversary this year, Kallfass has a competent partner at its side who knows the French market and its requirements. Among the numerous visitors to the EUROBOIS stand were many existing customers as well as some new business contacts. Hans Haist, Kallfass Managing Director, who is responsible for sales in France, will be travelling extensively over the next few weeks to turn discussions into real projects.

Sonderlösung: Beschickung von Trockenkammern mit Großpaketen EN Loading of drying chambers with large packages

Loading of drying chambers with large packages

Initial situation

It is best to load the channel dryers with large packages to reduce logistics costs for optimal utilisation. But automating these drying packs, which weigh up to 30 tonnes and are 6 m high, in often confined spaces is a challenge, and using forklift trucks causes increased repair and personnel costs.

Product solution: Automation on rails in a closed-loop system

The sawn timber is stacked into large packages on transport carts; the stack package is then pulled out of the hoist towards a shuttle and pushed onto it. The shuttle travels along a track channel with the drying pack and pushes the pack hydraulically onto the rails of the drying chamber. A buffer zone for empty transport carts ensures a closed-loop operation.

Kallfass was already able to inaugurate the structural work of the extended production hall in Klosterreichenbach, Germany with an internal celebration on 26 May 2023. The new offices in Wernigerode, Germany, will also be ready for occupancy shortly.

Kallfass Klosterreichenbach

10 May marked the anniversary of the structural expansion of the existing production hall in Klosterreichenbach. The shell of the L-shaped 600 m² extension has been completed and the access road to the new loading hall has already been paved.

The access road to the new loading hall is being paved.

Next up is the installation of a modern paint booth with integrated filter extraction and temperature control system. The spray cabin is divided into two cubicles, one behind the other, each 10 m long. Alternately, painting is done in one and drying in the other cabin. If necessary, the two cabins can be opened to form a large painting booth with a length of 20 m for painting particularly long machine parts. This flexible approach simplifies the production process enormously, because all the painting work that needs to be done is carried out in-house according to the customer's wishes.

The installation of a heating system will be another milestone. Here, sustainable heating with a water-fed heat pump is being considered and the statutory requirements are being checked. Together with the roof-mounted photovoltaic system already installed in 2014, the management is thus once again relying on renewable energies. The further interior construction of the hall with electricity and compressed air supply as well as the installation of filter and exhaust air lines are additional items on the to-do list.

If everything goes according to plan, the extension could be occupied as early as autumn this year. As a result, the production processes will be successively adapted and converted.

Modern workplaces in Wernigerode, Germany

In Wernigerode, the final move into the newly designed offices of the 160 m² annex is not far off. The construction of the interior is well advanced. Installation of the underfloor heating system and ceilings were completed, power lines have been installed, and walls facing the old building were removed, and new partition walls were installed and plastered. Next, the old building’s reception area needs to be redesigned so that old and new form a single unity. All employees from construction and administration had to move temporarily to the new premises to make room for the renovation work.

As soon as the new office furniture are delivered, the final move can take place, which is also planned in Wernigerode for autumn 2023. Only one and a half years after the start of construction, Kallfass employees will then have modern, ergonomic workplaces and spacious meeting rooms at their disposal.

Positiver Messeverlauf EN Positive results from the
trade fair

The Kallfass representatives at the LIGNA Trade Fair in Hanover, Germany were pleased to welcome a large number of visitors. The exhibition team was especially happy about the many sincere inquiries—from sawmill technology inquiries to cross-laminated timber projects.

After a four-year interruption, Kallfass was again looking forward to a very positive event at the LIGNA Trade Fair. “We met with many visitors. Above all, we welcomed customers and prospective clients from the German-speaking regions and other European countries at our stand. But also international representatives, such as from South Africa or Australia, were represented here," reported Kallfass CEO Hans Haist.

Specific inquiries

The Kallfass trade fair team was particularly pleased with many concrete inquiries from new and existing customers. “In particular, we noticed a strong interest in projects involving cross-laminated timber. But also our sawmill and planing automation systems were in demand," concluded Haist. In contrast to the years before, the first days were very busy. Towards the end of the week, things were quieter than usual, as other exhibitors at the Ligna reported.

At the Ligna, Kallfass presented three exhibits: its cross-laminated timber press, a robot for filling stick magazines and the tried-and-tested Tongloader®(see Holzkurier issue 18, p. 30). In addition to its remarkable vertical pressing force of 1 N/mm2, the CLT press scored high with its uniform pressure distribution across the entire board. To achieve this, Kallfass uses four cylinders per press row. The Tongloader® is used to cycle-in boards of different thicknesses and at the same maintaining a time high production speed in the sorting and planing units. The capacity is 240 cycles a minute. The Tongloader® can handle wet and dry goods. The patented robot handling system for stacking with strip placement was also very well received. “Filling the stick magazines with a robot increases performance and cycle speed”, explained Haist.

Kallfass at Ligna.23

Kallfass showed its CLT press at the Ligna - many inquiries were received for CTL projects.

The order books at Kallfass are well filled: In June, the installation of a box sorter at the Wolf sawmill in Germany will begin. The automation specialist also supplies this type of equipment to Eurolegnami in Italy, as well as to the Blanc sawmill in France. Also in June, Kallfass will install the entire automation factory for a planing mill, including a bundling system at Rettenmeier Baltic Timber in Latvia. The feed speeds of the afore-mentioned plant will reach up to 350 m/min.

Kallfass CLT Press, BSP Presse

Ausreichend Druck auf jedem Quadratmillimeter EN Adequate pressure on every square millimetre

With its CLT press, Kallfass meets the high demands that cross laminated timber producers make of flexible production. The panels are joined according to the zero joint principle. Process reliability is the top priority. There can be no compromising here if high panel quality and good approval values are to be achieved.

Kallfass, the automation professional from Klosterreichenbach/Germany, has already realised extensive mechanisation systems for CLT production in the past, including the KLH plant in Wiesenau, Austria and, also, various Stora Enso facilities in Ybbs and Bad St. Leonhard in Austria and Gruvön in Sweden. Kallfass incorporated the experience gained from this into the plant configuration at Stora Enso in Ždirec/Czech Republic last year. For the first time, an overall concept consisting of mechanisation and the company's own CLT press was offered, and another project with a CLT press is already in the implementation phase at best wood Schneider in Messkirch.

Pressing with maximum safety

Minimising interfaces is one of the central goals in every CLT plant. The step towards realisation of its own CLT press now offers Kallfass the opportunity to act as a main supplier for cross laminated timber production and optimally network production with a coordinated control concept. CLT process data and parameters can be recorded and archived on the master computer. For pressing, the press cake, which consists of single board layers glued crosswise and with a maximum height of 600 mm, is moved via a conveyor belt into the Kallfass CLT press. The CLT press consists of several press segments. The conveyor is reversible to enable return trips or emergency pressing in the event of a malfunction. This means that no valuable raw material is wasted and a degree of flexibility is achieved in production.

Kallfass CLT Press, BSP Presse

Flexible pressure

Pressing of single to multi-layer panels is realised with low maximum tolerance values of only 0.1 mm. This zero joint is achieved through a very high vertical pressing force of 1N/mm² in combination with uniform pressure distribution across the entire panel surface. Four cylinders are employed in each press row to ensure that the pressure is applied to every square millimetre. The pressure build-up is automatically controlled and adapted to the respective panel size, taking into account the elastic behaviour of wood. Furthermore, only those units and press punches required for the panel size are actuated. A speedier pressure build-up is achieved by pre-positioning the press plungers. Kallfass can supply its press with additional transverse pressure if wooden lamellas are to be pressed.

One press for numerous formats

The CLT press from Kallfass presses panel lengths from 8,000 to 16,000 mm and widths from 2,000 mm to 3,600 mm in a single pass. Individual panels can, at the customer's request, be automatically pushed off at the dry joint after the pressing process and separated again before being transferred to sanding machines or portal processing systems for further processing. When maintenance work is due, the press rams can be mechanically locked in the upper end positions to protect operating personnel. A continuous platform above the press facilitates accessing of hydraulic and electric systems.

30 years Kallfass Wernigerode

30 Jahre KALLFASS Wernigerode EN 30 years of KALLFASS Wernigerode

Management and around 60 employees from Klosterreichenbach and Wernigerode met on 21 October 2022 to celebrate the 30th anniversary of the Kallfass plant in Saxony-Anhalt.

In 1992, two years after German reunification, Senior Partner Ernst Kallfass secured the strategic growth of his company by establishing a second plant in Wernigerode. The choice of Wernigerode in Saxony-Anhalt at this time was in part a reflection of the sentiments associated with reunification. East and west would also be united in Kallfass. The early years were extremely difficult, but 30 years later, the plant in Wernigerode is an important mainstay of Kallfass as an enterprise, continually undergoing constructional changes to adapt to new requirements.´

Following repeated expansion of the production area in Wernigerode in the past, the office and administrative building will now be enlarged by 160 m² to accommodate the growing number of staff. Management decided to go the whole hog in the anniversary year and commenced with the necessary building measures. New parking spaces were created in April, as the old car park had to make way for the new office extension. Construction of the actual extension then commenced in June, and 50 % of construction measures were completed in time for the anniversary celebration. Expansion of the production facility in Klosterreichenbach is simultaneously making great strides.

The celebration to mark the anniversary provided an opportunity to bring employees from both Wernigerode and Klosterreichenbach up to date with regard to construction progress at both sites and inform them of the future direction of corporate goals. It also saw long-tenured employees being honoured for their many years of loyal service.

The considerable distance between the locations means that employees from Wernigerode and Klosterreichenbach seldom have the opportunity to meet personally, with project meetings being generally held online and by telephone. Joint events such as the anniversary celebration offer a welcome change from this. Plant Manager Enrico Goldhahn's team simply brought the Oktoberfest to Saxony-Anhalt to mark the anniversary, and a Bavarian buffet and freshly tapped beer encouraged a convivial exchange between colleagues from both east and west.

DER NORDSCHWARZWALD UND SEINE WELTMARKTFÜHRER EN The northern Black Forest and its global market leader

In addition to being a major tourist attraction, the Black Forest is also a centre of development in the area of wood processing, with numerous global market leaders and mechanical engineers in the region involved in this sector. Forum Weisstanne reports on this in its anniversary magazine.

Forum Weisstanne, an association run by volunteers that seeks to improve the market situation of the Black Forest SILVER FIR, issued the Faszination Weißtanne magazine, a publication dedicated to the allure of the silver fir, in September to mark the occasion of its 25th anniversary. Over 40 reports address construction, architecture and marketing associated with regional timber. One contribution is dedicated to the Northern Black Forest and its global leaders in wood technology and engineering, including firms such as Linck, Kallfass, Homag and Schmalz.

The following is an excerpt from the article:

The Northern Black Forest – global leader in woodworking and wood processing engineering

The Northern Black Forest is a densely wooded area rich in timber that is frequently popularised as an attractive tourism destination or, indeed, a booming forestry and timber region.
And all this is true! But it is not the entire story, as the Northern Black Forest is also a region that produces many inventors. Most Germans are familiar with the Fischer plug, and many of them also know that these fixing elements were invented and are produced in the Black Forest. However, beyond the Black Forest, not many people know that the Northern Black Forest is centre of invention and development in woodworking and wood processing machinery.

The most widely known inventor in this respect is probably Max Himmelheber. Born in 1904 in Karlsruhe, Max grew up in a carpentry and joinery shop where he saw at first hand how large quantities of wood chips largely went unused. He began to tinker about with this material at an early age and, later as an electrical engineer, he examined options for using waste wood material. Max ultimately invented the chipboard in the 1930s, a development that we would today call a “turning point in the utilisation of wood”. Max Himmelheber then founded a company in Baiersbronn and established chipboard factories all over the world, issuing production licences to around 80 firms.
However, this was only the beginning of the machinery boom for woodworking and wood processing in the Black Forest. Numerous machine manufacturers are active today in this sector.

Kallfass GmbH – Maschinen plus Automation, Klosterreichenbach, District of Freudenstadt

KALLFASS has been developing and producing machinery and systems for sawmills and the global timber processing industry in Klosterreichenbach, Germany since 1949. Kallfass solutions are customised and range from charging of small process units to the mechanising of complete production lines for sawing, planing, glueing, pressing and sorting of timber.

As a family-run business in its third generation, KALLFASS employs around 120 people at its main facility in Klosterreichenbach, Northern Black Forest, and another production location in Wernigerode (Saxony-Anhalt). The development, design, production, assembly and programming of plants are all realised completely in the company.

Wood harbours enormous potential for further development, thanks to the numerous options available for its use. KALLFASS helps its sawmill customers to implement innovative product ideas and achieve special production requirements in practice and develops tailored fully automated process and plant technology. KALLFASS has readied a wealth of new developments for series production.

This success has also been demonstrated by the KALLFASS multiple circular cross-cut saw. Designed in 1965, its precision and flexibility in wood cutting has today made it the global leader among multiple circular cross-cut saws in this sector, and it is integrated in cutting systems and sorting and planing plants. The tried and trusted KALLFASS box sorter is a further success story. Timber in a variety of dimensions can be stored in the interim in large space-saving boxes for further use. This means that packages with the same dimensions and quality can be created later from different boards from the same log.

Karriere und Elternzeit bei Kallfass

Betreuungsmodell Elternteilzeit EN Parental part-time work care model

The early years of a child's development are one of the most significant periods and are an important time in order to build an intensive bond. Part-time parental leave is a great alternative to full-time work. It allows mothers and fathers to be able to strike a balance between family and career. Fewer hours can be worked and working hours can be arranged differently. Contrary to “regular” part-time work, the employee is also entitled to the original contractually agreed upon working hours again after the parental part-time work has expired. Furthermore, there is special protection from termination of employment whilst this part-time parental leave is in place.

The legislator has provided for a total duration of 36 months for parental part-time work. Of these 36 months, at least 12 months must be before the child’s third birthday. The extent and duration of part-time work can be determined individually. Although, there is still an entitlement to parental allowance; however, the remuneration for the part-time work is considered.

Karriere und Elternzeit bei Kallfass

What are the conditions for parental part-time work?

In order for this care model to be effective, the workplace must be suitable for part-time work and the employment relationship must last longer than six months without interruptions. The weekly number of hours is between 15 and 32 hours for part-time workers. The type and extent of part-time work must be synchronized with the management. Early arrangements help to pave the way, especially with regard to avoiding potential problems. Moreover, it is important that part-time work is applied for in writing in a timely manner. The deadlines are 7 weeks if the child is younger than 3 years and 13 weeks if the child is between 3 and 8 years old.

At KALLFASS, this care model has already been implemented several times and even employees in managerial positions have been able to take advantage of parental part-time work. The be-all and end-all is good planning and adherence to the agreements. This will ensure a smooth parental leave.

Kallfass Gebäude Klosterreichenbach und Wernigerode

Kallfass investiert in die Zukunft EN Kallfass invests in the future

Short production routes in Klosterreichenbach and more office space in Wernigerode are the goals of these construction measures.

When the demand for orders increases so dramatically that production reaches its limits in terms of capacity and the electrical department urgently needs more space to accommodate the increase in personnel, the only viable solution is to build and expand the existing production and office premises. Last year, the machine manufacturer Kallfass decided to go all out and invest and build in both locations.

The production area in Klosterreichenbach will be increased by approximately 600 m². An L-shaped extension to the existing production premises facilitates the improved integration of individual production stages in a direct time sequence. Routes are shortened and the entire production facility made more efficient as a result. Building commenced on 10 May. Planned completion is the end of this / start of next year.

Excavators begin digging out the foundations in Klosterreichenbach.

New offices in Wernigerode

New offices are urgently needed at the plant in Wernigerode, Saxony-Anhalt. The production area was continually increased in recent years, but the offices have not been changed since 1992, even though the workforce has tripled in this period. Enlarging of the administrative premises by around 160m² to a total of 480m² is planned. The first implementation stage will see the creation of new parking spaces, as the extension will be erected on the original car park. Work on this stage has already commenced. Enrico Goldhahn, Plant Manager in Wernigerode, looks forward to completion of this extension by the beginning of 2023.

Both extensions represent an important step in accommodating the growing demand in future.
