Abstract: An apparatus and process are provided for the production of plywood. The apparatus is adapted to form plywood panels without prior patching of defects in the veneer sheets used to form the panel. The formed panel then is electro-optically scanned to identify and locate defects. The sensed defect data is stored in a control unit which in turn directs a defect removal apparatus and a patcher to appropriate locations for removing and patching the defects.
