AltholzKnapp – Specialist for historic oak

Knapp – Historische Baustoffe GmbH has been one of the leading suppliers in the reclaimed wood sector for over 40 years. The company primarily processes historic oak beams into sawn timber, flooring boards, furniture panels and custom carpentry products, consistently focusing on sustainable reuse.

The SERRA KE90 as the heart of production

In daily production, Knapp has been using a stationary SERRA KE90 block band saw since 2011. It has proven particularly effective for the precise cutting of old, hard oak beams. The machine handles cross-sections up to 90 cm and offers cutting lengths of around 6.7 m – ideal for massive historic beams. The high cutting quality is especially noteworthy, even when processing extremely hard material.

Why Knapp relies on the KE90 block band saw

• High precision: The wide-band technology and the design of the KE90 ensure consistently clean cuts for diameters up to 90 cm.
• Robust construction: A fully hot-dip galvanized base frame guarantees long service life despite harsh conditions in reclaimed wood processing.
• User-friendly operation: Stepless electric feed, electric height adjustment and a clearly arranged control station make daily work easier.
• High reliability: Knapp praises the robustness of the machine, which operates reliably over the long term despite the hardness and density of the material.

“The SERRA KE90 has become indispensable for us. It is the core of our mechanical processing and therefore the basis for offering such a wide product range made from reclaimed wood. Custom cuts in almost any material are simply not an issue. From ceiling beams and rafters to polygonal columns, sawn veneers and sawn timber from historic oak beams – we manufacture all of this in any desired dimensions. In short: no one here can imagine working ‘without SERRA’ anymore,” reports Benjamin Staude.

The SERRA KE90 is a central component of AltholzKnapp’s production. It enables precise, robust and flexible processing of historic oak beams and thus makes a significant contribution to the high quality and diversity for which Knapp is known.
