Patent DE-4122365-A1 (DE)
IPC: B27L5/06
Filed: 1991-07-05
Abstract: It has been found that, in solid wood laminate panels which are glued in layers and are manufactured from boards cut without removal of shavings, edge waviness may possibly occur in the outer area in the face of extreme climatic stress. This problem is removed according to the invention owing to the fact that boards which have not been produced by cutting, specifically the residual boards obtained during the cutting production of boards from squared timber or conventional boards produced by saw cuts, are used for a centre layer of the laminate panel.
