ABSTRACT:
Apparatus for feeding boards in a single direction sequentially from the bottom (or top) of a stack through a feed gate, comprising three parallel rows of frictional contact conveying wheels (24) each row driven by a separate electric motor (21, 22, 23). The boards (12) are fed sequentially onto an output conveyor (1) without nip rolls. An electronic control system (27) accelerates the three rows of wheels (24) simultaneously to line speed and progressively decelerates each row of wheels when the trailing edge of each board has advanced and before the next succeeding board has descended. The conveying wheels (24) project through apertures in a suction box (16) which holds the boards in contact with the conveying wheels during conveyance. The boards are fed without crush accurately and in perfect register without slipping and with minimum power requirements.
