ABSTRACT:
A sheet feeder is disclosed having a cartridge mounted adjacent the stack of paper providing an exposed line of adhesive strip. The adhesive should be a temporary adhesive which when removed leaves no residue or damage on the sheet to which it was temporarily bonded. The cartridge is landed on the top sheet of paper adjacent the leading edge of the sheet, and the cartridge is then rotated away from the direction in which the sheet is to be fed while maintaining a minimum amount of pressure on the top of the stack. This effectively bonds the gummed strip on the cartridge to the edge of the top sheet of paper; and the motion away from the feeding direction lifts the top edge of the sheet from the edge of the sheet below, which now forms the top of the stack. The sheet below, also to be called the second sheet, remains in place because of the combination of downward pressure against the second sheet near its leading edge created by the cartridge, together with the beam strength of the paper which tends to cause the sheet to continue to lie flat. The cartridge can now be moved in the feeding direction, presenting the sheet of paper to an entry path to the copying machine.
