US11285634B2	Veneer sheet conveying apparatus and method of controlling the same When a veneer conveyed out by a discharging conveyor is a product veneer, a sorting apparatus is rotationally driven to pierce the product veneer with needle-like bodies by a guide member and a push-up member (a rolling bearing).
