From 26 - 30 May 2025, the entire woodworking community will gather in Hanover, Germany. More than 1,200 exhibitors from all over the world will be represented, occupying approx. 112,000 m² of exhibition space. As an automation professional and system manufacturer, Kallfass will be showcasing its products on its 126 m² booth.

Kallfass at the Ligna trade fair: Hall 25 / Booth D66

Plenty to see at the exhibition stand

On display will be a multiple cross-cut saw for unedged goods with four saw aggregats; three of which can be individually positioned.

Whether boards, panels, squared timber or round bars, the Kallfass multiple cross-cut saw cuts raw or planed workpieces—individually or in layers—to the required lengths with millimetre precision, even with a mitre cut if required. The saw works with a high cutting accuracy of only ±1 mm tolerance. The saw aggregats, which can be individually positioned, are automatically aligned to the new cutting pattern in the shortest possible time. The multiple cross-cut saw is a Kallfass classic.

In a live demonstration at the trade fair booth, Kallfass will show how a robot can handle wooden sticks fully automatically.

When stacking wood packs with automatic stick placement, several stick magazines must be constantly loaded with stacking sticks. When using double magazines, even with two different stick dimensions. This very time-consuming filling of the magazines can be carried out by a robot, at a constant output and high cycle rate. If required, a second robot even cycles the sticks into the buffer conveyor beforehand. A high-performance solution for state-of-the-art, fully automated production of sawn timber.

50 years of Kallfass at LIGNA

The first LIGNA trade fair was held in Hanover, Germany, in 1975 and Kallfass was an exhibitor right from the start. Hannover Messe used the 50th anniversary of the trade fair as an opportunity to launch a series of interviews entitled “LIGNA Story”. Companies that are also celebrating a LIGNA anniversary this year were surveyed. Company owner Ernst Kallfass answers questions in the Kallfass Story.

To the LIGNA interview

At LIGNA, Kallfass will also be introducing its new regional representative in the Netherlands. With Herwin Horstman from ESTUFA B.V., Kallfass has gained a competent sales partner who knows the wood processing market in Holland very well and can support local companies in their native language.

From a small workshop to global player

In 2024 Kallfass celebrates 75 years of success in mechanical and plant engineering. During this time, the family-run company–now in its third generation– has completed well over 1,000 complex projects for the woodworking industry. The long-established Black Forest company has made a name for itself worldwide, particularly as a mechanisation specialist and solution partner.

Founded in 1949 by Ernst and Frida Kallfass as a small workshop in Klosterreichenbach, Germany, the company initially carried out repair work for the local timber industry. However, the resourceful company founder soon developed his own machines, such as the groove and dovetailing machine or the firewood press. The machine programme took a pioneering direction in 1965 with the development of the multiple cross-cut saw for the efficient cutting of fixed lengths. After continuous further development, thanks to its precision and flexibility, it is now one of the market-leading multiple cross-cut saws in the wood cutting sector and is integrated in cutting systems as well as in sorting or planing mills. Kallfass was also one of the pioneers in the stacking of sawn timber. Ernst Kallfass' stacking system was the first ever on the market.

The founder's son, Ernst Kallfass Junior, joined his parents' company in 1975 at the age of 24. Nine years later, he was handed the company’s reins and acting as Managing Director. He developed box and level sorting systems and combined them with cut-to-length and stacking systems to create a production line. This was the start of complex sawmill projects that opened up a new customer base. The complex systems required more production capacity and so in 1992, after the fall of the Berlin Wall, he founded a second plant in Wernigerode, in the German state of Saxony-Anhalt.

In Klosterreichenbach, the opportunity arose at the beginning of 2019 to acquire the building of a former machine factory in the neighbourhood. Ernst Kallfass did not hesitate for long and seized the opportunity. Since then, Kallfass Plant 3 has been used as an interim storage facility for test installations and, to a limited extent, for production.

Currently, around 120 employees work in all three plants. The plant technology is developed, planned, designed, manufactured, painted and installed on entirely in-house. While remaining market-focused and product-focused, Kallfass has successively expanded its product range over the years. Today the company offers systems and complete mechanisations with integrated safety and control concepts for the production of construction, packaging and garden timber as well as glued wood products.

Specialised in complex mechanisation

Kallfass is known in the industry as a machine supplier who pragmatically harmonises the customer's requirements with the available space and develops the best technical solution for the situation. The company’s aim is to maximise production output and to achieve the highest possible degree of automation.

Some process solutions for automation were so unique that they were patented. In addition to the patent for the first layer-by-layer processing of sawn timber back in the mid-1980s, Kallfass also received patent protection for its robot handling in 2019. When stacking timber packs with automatic stick placement, the magazines used for this no longer have to be filled manually, but can be constantly filled with wooden sticks by a robot.

The transport system for large parcels is another example of an innovative logistics solution. Packages of wood weighing up to 30 tonnes and 6 m high are transported into the drying chambers on rails using transport trolleys. Subsequently, they taken out again for further processing, without the need for a forklift truck. An extremely cost-saving circulation system.

However, it is not only special partial solutions in automation that distinguish the machine manufacturer, but also its expertise in the design of complete production lines for sorting, cutting to length, packaging, planing and gluing, into which it integrates equipment from other suppliers in an interface-optimised manner, such as quality scanners and labellers. At the customer's request, the product data can even be processed directly from the customer's ERP system. This is what Kallfass means by “Solutions from a single source”.

Kallfass also developed its own systems for glulam production, including a CLT press, which was also launched in 2019. The term CLT stands for Cross-Laminated Timber, one of the most important building elements in modern timber construction. The Kallfass press continuously presses individual, cross-glued panels into multi-layer panels with lengths of up to 16 m. With its own CLT press, Kallfass has also succeeded in rounding off its product portfolio in this area. Kallfass can offer complete mechanisation, from picking up the sawn timber packages to accepting the finished cross laminated timber elements.

Well positioned for the future

Six years ago, Ernst Kallfass set his company up for the future. He appointed his son Volker Kallfass and his long-time companion Hans Haist as additional Managing Directors and gradually withdrew from the operational business in order to concentrate on the strategic direction of the company. This also includes structural expansion measures, such as increasing the production hall in Klosterreichenbach, which was completed end of 2023, and the office expansion at the Wernigerode plant.

Over the years, the plants in Klosterreichenbach and Wernigerode have been adapted several times to meet changing requirements. In 2022, the decision was made to expand the production area at the Klosterreichenbach site by another 750 m² in order to better dovetail individual production steps in a direct, chronological sequence. Shorter distances are the result and with them a more efficient production process. A state-of-the-art paint booth also ensures greater efficiency and flexibility. It was designed as two cabins, one behind the other, each 10 m long. If necessary, the cabins can be opened to paint particularly long machine parts.

In Wernigerode, on the other hand, the focus was on more administrative space in order to cope with the growing number of employees in the electrical design and software development departments. Thanks to the 160 m² extension, modern office space totalling 480 m² has been available since the end of 2023.

With these expansion measures, Kallfass is well positioned for the future.

A reason to celebrate

At the beginning of June, Kallfass will celebrate the successful completion of its remodelling measures and, above all, its 75-year success story with the entire team of employees and invited guests at the Kallfass plant in Klosterreichenbach. The production hall will be transformed into a party mile. A music band, various food trucks and a cocktail bar provide the perfect setting for an exuberant evening event.

The following day, Saturday June 8, there will be an Open House at Röter Straße 44. Anyone interested can take this opportunity to get an idea of the production scope of the globally active machine manufacturer and see the new production hall from the inside. Those who wish can join guided tours and those who are still looking for an apprenticeship will be informed about possible apprenticeships at Kallfass at the apprentice info point. It is not necessary to register for the Open House. Admission starts at 11 a.m. and catering will of course be provided. A children's carousel is available for younger guests.

Over the years, Kallfass has undergone a transformation from a small workshop to a modern medium-sized company. With a great deal of hard work, development creativity and market knowledge, the company now plays on the international stage and, thanks to its wide range of activities, offers work and prospects to a wide variety of professions. The order situation remains good and production is fully utilised. For this reason, software developers, programmers, designers and technicians are being sought in both Wernigerode and Klosterreichenbach to help shape the future of Kallfass.

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.

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.

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.

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.
