Until now, a relative high degree of culling occurs as a result of wrinkling and fissuring in sensitive types of wood when veneer is dried. According to the new method for drying veneer, wrinkling and fissuring is substantially prevented thereby minimizing culls. The drying device makes it possible to substantially automate the implementation of the inventive method. The veneer is fed through the dryer in such a way that the direction of the grain of the veneer is slanted in relation to the direction of conveyance. The feed device in the drying device is embodied in such a way that the veneer is placed in the envisaged slanted position as it is fed to the dryer. Reversal of the slanted position is performed by the removal device. The veneer is dried.
Le séchage de plaques de bois de placage entraîne traditionnellement pour les essences de bois fragiles un rebut relativement abondant dû aux plis et aux fissures. Le nouveau procédé de séchage de plaques de bois de placage selon la présente invention permet d'éviter dans une large mesure la formation de plis et de fissures et, partant, de limiter le rebut. Le dispositif de séchage associé permet la mise en oeuvre largement automatique dudit procédé. Les plaques de bois sont transportées à travers le séchoir de manière telle que le sens des fibres des plaques de bois se trouve en biais par rapport au sens de transport. Dans ledit dispositif de séchage, le dispositif d'alimentation est ainsi conçu que les plaques de bois sont amenées à la position en biais prévue lors de leur introduction dans le séchoir. Le dispositif d'évacuation ramène le sens des fibres dans une position parallèle au sens de transport puis le placage est séché.
