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. The chain includes knife tips with angularly disposed serrations which engage the surface of the log from which veneer is being cut. As the log is rotated about its longitudinal axis, the friction between the log and knife tip serrations imparts longitudinal movement of the chain with respect to the log. The chain thereby moves around the chain bar so as to cut a layer of veneer from the log. No separate power source is required for rotating the chain.
