Abstract
Abstract A veneer drying machine comprises coacting endless flexible conveyor belts between which the sheets of veneer are conveyed on a path that passes between superposed pairs of heating plates. The upper of the two heating plates is vertically movable to permit movement of the coacting conveyor belts therebetween. When the upper heating plate is lowered, the conveyor belts with the veneers between them are held stationary and veneers are then dried. An overhead hood withdraws steam emitted by the hot veneer.
