Abstract:Zusammenfassung The production of plywood from previously compressed veneer allows to save up to 25% of glue, to halve the roughness of veneer and plywood and to press the plywood at a 22% lower pressure. However, the thickness of plywood reduces from 8.3 mm for uncompressed veneer to 6.4–8.0 mm for compressed veneer, and the density increases from 793 kg/m3 to 807–1005 kg/m3 accordingly.
