ABSTRACT:
A veneer clipper of rotary type is disclosed wherein a cutting knife carried by an intermittently rotatable knife carrage roll cuts through a veneer sheet moving past an anvil roll. The clipper has a plurality rotatable back-up rolls which are movable reciprocally toward and away from the carriage roll. In their operative position, the back-up rolls are pressed against the circumferential surface of the carriage roll for bracing the same to counteract the reactional pressure exerted by the anvil roll during veneer cutting. There is provided means for driving reciprocally the back-up rolls in conjunction with the intermittent rotation of the knife carriage in such a way that the back-up rolls may be kept in pressing contact with the knife carriage roll at least while the veneer sheet is being cut by the knife and then moved away from the surface after each such cut.
