DUOZINK cycle center for modern wood processing
Demands in the wood industry are constantly increasing: Manufacturers of GLT, KVH, or cross-laminated timber require systems that deliver high cycle rates, flexible dimensions, and consistent, high-quality results. HOWIAL’s DUOZINK finger-jointing systems exactly meet these requirements, combining state-of-the-art technology with decades of experience. This enables you to create a production process that is both economical and future-proof.
A DUOZINK cycle center is used for production capacities ranging from 900 to 2,250 running meters per hour. DUOZINK finger-jointing systems feature advanced finger-jointing technology that divides the necessary process steps—milling, glue application, and pressing—into separate stations.
DUOZINK finger-jointing system – Versatility for all dimensions

Whether it’s construction timber, laminated wood, or load-bearing wood-based materials—the DUOZINK is highly versatile. Depending on the model, wood widths from 60 to 320 mm and thicknesses from 20 to 180 mm can be processed. This means the systems cover virtually all relevant cross-sections required in modern wood processing.
This cycle center is characterized by its very compact installation space. Both vertical and horizontal finger-joint connections are possible, too. In addition, both 1K and 2K glues can be used. For companies that prioritize versatility and adaptability, DUOZINK is the ideal solution.
The following cross-sections can be finger jointed:
Board length on the input side: 800 – 6,000 mm
Board length on the output side: 2.000 – 50,000 mm
Board thickness: 20 – 180 mm
Board widths: 60 – 320 mm
Pressing force: 150 – 300 kN, hydraulic
Running meters capacitiy: 900 - 2.250 m/h
Maximum productivity while the DUOZINK finger-jointing machine is in operation
Productivity is a decisive factor in every production facility. With a cycle rate of 12 to 18 joints per minute, the DUOZINK cycle centers guarantee high availability and reliable throughput. Thanks to pressing forces of up to 300 kN, stable and durable joints are created that perform well in both load-bearing structures and visible applications. This allows you to increase the efficiency of your entire production chain.
DUOZINK finger-jointing systems – Precision down to the last detail
A high-quality finger-jointing system is characterized by precise joints. DUOZINK cycle centers utilize state-of-the-art milling technology, precise gluing, and uniform pressing. The result: clean, offset-free finger joints without tear-outs or compromises in quality.
