Abstract: A veneer lathe log peeling apparatus and method of producing wood veneer are disclosed employing a powered back-up roll for adding torque to and preventing deflection of log cores of small diameter. The powered roll and an idler roll are positioned in contact with the side of the log in spaced relationship so that the resultant force vector of the cutting forces produced by the lathe knife and the nose bar is directed between the idler roll and the powered roll. The angular and radial positions of the idler roll and the power roll relative to each other and with respect to the axis of rotation of the log are independently adjusted by an automatic control means, in response to decreases in the diameter of the log being peeled.

Abstract: An improved chuck assembly for use in a veneer peeling lathe has retractable chuck pairs comprised of inner and outer rotatable chucks. At least one of the smaller inner chucks has a plurality of relatively chisel-like teeth extending outwardly from the base in a star pattern. At least one of the larger outer chucks has a plurality of thin chisel-like teeth extending outwardly from the circumferential edge of a body member. An improved means for removably attaching the large chuck to its spindle is provided.
