Abstract
Apparatus is disclosed for automatically stacking pieces of limp material including an endless conveyor having a forward traveling upper reach. The conveyor has a series of flights spaced at intervals therealong with spaces between the flights. Each flight is constructed for carrying one of the pieces thereon with the piece so positioned on the flight as to have a trailing end overhanging the trailing end of the flight. The apparatus further includes a platen or table at a stacking station along the length of the upper reach of the conveyor and below the upper reach for stacking pieces thereon one upon another and for holding the stack. A gripper mechanism is engageable with an upwardly facing surface of the piece for gripping the piece to stop it from moving forward. Thereafter, as the flight travels forward it moves out from under the piece and the piece is deposited at the station for accumulation of piece one on top of another on the table.
