Abstract

The system includes a veneer lathe, a conveyor or apron (50) onto which the veneer from the lathe is initially directed, followed by a combination of an anvil roller (54) and a rotating clipper knife (62), which in turn is followed by a trash gate (72). The speed and rotation of the knife (62) is controlled such that the veneer material produced by operation of the lathe is first cut upon recognition of the start of random veneer and then again upon the recognition of the start of ribbon veneer. The trash gate (72) is controlled synchronously with the operation of the knife (62) such that the trash gate (72) is open up to the point in time where the veneer trash is cut from the remainder of the veneer material, at which point the trash gate (72) is closed.
