Abstract (en)
[origin: US6431539B2] The invention concerns a method for unstacking sheets stacked in a feeder, comprising a step which consists in bringing a vacuum cup close to the surface of the sheet at the top of the stack; a step which consists in contacting the vacuum cup with the surface of said top sheet and a step in bringing the vacuum cup away after seizing the top sheet. The invention is characterized in that the vacuum cup is applied in an off-center zone of the top sheet, and said vacuum cup is inclined, when it starts to move away, so as to cause the top sheet to be deformed thereby producing a separation prior to complete separation of the top sheet.
