ABSTRACT:
A system for detecting offsize defects and for segregating the veneer sheets containing the defects from the non-defective sheets. Scanners are positioned along the in-feed conveyor leading to the clipper. As offsize defects are identified, a computer determines which of the sheets to be cut will contain the defects. These sheets are segregated as by diverting them to a pull chain conveyor following the cutting of the sheets from the continuous sheeting. Dye is sprayed on the area of the defects as detected by the scanners to aid in further handling of the defective sheets when removed from the pull chain.
