ABSTRACT:
A veneer processing apparatus squeezes water out of a crude veneer when the veneer is inserted into the apparatus in such an orientation that fibers thereof extending substantially parallel to an intended direction of veneer insertion, and forms short splits in the veneer when the veneer is oriented such that the fibers extend substantially perpendicular to that direction. A pair of rolls each being provided with teeth thereon are so located as to cause their teeth to become aligned with each other at a predetermined position for veneer insertion. Each teeth is indented to have alternating projections and recesses. In the position for veneer insertion, the projections of the teeth on one roll are substantially interlocked with the recesses of the teeth on the other roll or are spaced from the projections of the teeth on the latter roll by an amount which is smaller than the thickness of the veneer. The recesses are filled with sponge or like elastic material. The rolls may each be replaced with an assembly of annular roll elements coaxially mounted on a rotary shaft, or an endless belt which is passed over rollers.
