Load-bearing columns made from veneer

Researchers at the University of Kassel have developed a process in which ceiling elements and supporting pillars are made from coiled veneer wood.

Robots from ABB are used. Together with Oest Systems and the adhesive manufacturer Jowat, the University of Kassel has developed a sophisticated end effector with a pump system for applying the adhesive. It can simultaneously extrude, glue and automatically cut the beech veneer strip, which is delivered on 200-meter rolls. Two integrated compression springs in the end effector can be used to set a defined tensile force on the veneer strip. This ensures sufficient contact pressure for gluing in the winding process. Subsequent pressing using formwork or vacuum bags is no longer necessary.
