FLEXIBLE SORTING SOLUTION FOR WOLF
German sawmill Wilhelm Wolf recently invested in a new, flexible sorting system from Kallfass
The previous sorting system at the Wilhelm Wolf sawmill in Waidhaus, Germany, was performance-limiting and too labour- intensive. That is why junior manager Christian Wolf decided to invest in a new, flexible sorting system from Kallfass. In retrospect, it was the right decision for him – for several reasons, as he reported. With a cutting capacity of around 25,000m3 per year, the Wolf sawmill is a classic small to medium-sized enterprise. The company’s history dates back to 1870 and, today, Christian Wolf runs the firm in co-operation with his mother, Gabriele Wolf, and represents the fifth generation of the family-run company.
When using a gang saw and a small profiling system, and a downstream circular edger saw, the production of solid structural timber (KVH), glued-laminated timber lamellas, packaging squared timber, side products or raw goods from sawn timber (rough planer) is relatively easy. The classification and stacking of the diverse assortments were previously carried out using a simple length sorting system. In this case, employees subsequently stacked the sawn timber manually.
“It was too labour-intensive and we find it very difficult to recruit staff,” said Mr Wolf.

“In addition, this sorting has significantly limited our performance,” he added. “In order to become faster and more flexible, a new solution was needed.
