  • Patent number: 5235518
    Abstract: A veneer composer transfers veneer pieces intermittently on a conveyor, detects the transfer of each veneer piece, cuts the veneer piece into an available width based on a detected signal, joins the veneer pieces end to end to form a composed veneer plate of long length, and cuts the composed veneer plate into a predetermined full size. The conveyor is connected to servo motors and a digital control circuit. The digital control circuit controls operation such that when the conveyor is restarted after an operation of cutting a veneer piece, a buffer acceleration time (Ta) approximately from 40 ms to 200 ms is set for the conveyer, and that when the conveyer is decelerated for setting the veneer piece to a predetermined cutting position, a buffer decelereration time (Td) approximately from 80 ms to 200 ms is set for the conveyor.
