Abstract
Apparatus for feeding boards (10) sequentially in one direction from the base of the stack through a feed gate (11) at the base of a front stack retaining wall (12) comprising a transverse series of perforated reciprocating conveying straps (14) mounted on driven pulleys (15) and interposed between a transverse series of lifting bars (13) with a drive mechanism for lowering and raising the lifting bars (13) sequentially and in synchronization with forwards and rearwards movement respectively of the conveying straps (14). A suction box (17) causes the lowermost board to be held in frictional driving contact with the upper surfaces of conveying straps (14) as the board is conveyed forwards into the nip of a pair of feed rolls (40) of, for example, corrugated board handling machinery.
