Abstract: The disclosure relates to a sheet spreader for a sheet feeder apparatus comprising at least one pair of sheet clamps, a guideway extending along an entry to a sheet feeder, clamps mounted on the guideway for movement along the entry to the sheet feeder and a plurality of sheet loading stations located at fixed positions opposite the guideway. Each loading station has a sheet clipping system to receive and support a pair of corners of a sheet and for effecting transfer of the sheet corners from the clipping system to the pair of sheet clamps on the guideway when the clamps are located in a transfer position adjacent the loading station. The sheet clamps of each pair move independently of one other, first together in a transfer position at a respective loading station and then apart to spread the sheet received at a loading station for entry to the sheet feeder.
