ABSTRACT:
A method and apparatus minimize the amount of waste veneer cut by a rotating veneer lathe after a peel break by coordinating the contour of the previous peel spiral with the motion including the path, speed, and position of the knife as it reengages the surface of the rotating log from which the veneer is cut. Upon a command to resume peeling, the knife moves from a standby location toward the surface of the block at a first peel rate and reengages the block at a second peel rate. The approach path toward and entry location on the surface of the rotating block defined by the first and second peel rates promote the cutting of continuous veneer of a desired thickness at the largest possible block radius.
