Sheet feeder has a double suction pair arrangement for separation of the leading edges of sheets in a stack, which ensures the sheets are handed over and positioned correctly on a transport device

摘要

Sheet feeder for cyclic transport of sheets has a sheet forward edge separator with two adjacent double suction pairs. Each double suction pair comprises two double suction units (9, 9). The movement cycle of the double suction units of the double suction pairs has a phase difference (15) at least in the region of the sheet hand over position to the transport unit (3). The phase difference can be adjusted so that it is positive or negative. The invention also relates to a corresponding method.
