摘要

A lathe for peeling logs to produce veneer for making plywood or the like. The lathe includes sets of inner and outer dogs supporting each end of a log being peeled. A reciprocating-pressure bar or roller is included for engaging the peeled veneer adjacent to the knives. The lathe is operated by a programmed controller. The radius of each log being peeled is determined by the controller based on the position of the pressure bar or roller after round up of the log. When the radius of the log is greater than a preprogrammed value, the log core is released from the lathe after peeling to the diameter of the outer dogs. When the radius of the log is less than the preprogrammed value, the log core is released from the lathe after peeling to the diameter of the inner dogs. The controller automatically determines to which core diamter each log is to be peeled.
