ABSTRACT:
A continuously moving lathe knife is provided which can be retrofit to an existing lathe carriage. The knife assembly includes a chain bar secured to the knife carriage with a pair of sprockets at either end of the chain bar. An endless loop chain extends around the sprockets. A power source rotates one of the sprockets so as to rotate the chain around the sprockets. The movement of the chain is guided by a channel in the chain bar. Each link of the chain includes a knife tip for cutting a layer of veneer from a wooden log which is rotated about its longitudinal axis as the chain is rotated in a plane parallel to the log surface.
