A holder for receiving sheets and discharging sheets therefrom one-by-one from the bottom of a stack of sheets is provided including a carrier having a rear portion, an intermediate portion and a front portion, providing a carrying surface for the sheets, the carrier being bent at the intermediate portion thereof, transverse to the direction of conveyance of the sheets, so as to create a deepened section between the rear portion and the front portion. Lateral supports extend from lateral edges of the carrier, with at least one elevated part provided in the deepened section at the intermediate portion extending transverse to the direction of conveyance on the carrying surface of the carrier. At least one aperture is provided in the carrier near at least one of the lateral supports in the vicinity of the deepened section of the carrier and the elevated part, beneath at least one edge area at a side of the stack of sheets accommodated in the holder, such that a partial vacuum can be produced, by way of the aperture using a vacuum device. A device for introducing and blowing air across the deepened section of the carrier against the side of the stack of sheets creates an air layer between the bottom sheet in the stack of sheets and the remaining sheets in the stack. A transport mechanism discharges the bottom sheet.
A holder for receiving sheets and discharging sheets therefrom one-by-one from the bottom of a stack of sheets which comprises a carrier having a rear portion, an intermediate portion and a front portion, together providing a carrier surface for said sheets, said carrier being bent at said intermediate portion thereof, transverse to a direction of conveyance of said sheets, so as to create a deepened section between said rear portion and said front portion, lateral supports extending from lateral edges of said carrier, at least one elevated part in said deepened section at said intermediate portion extending transverse to said direction of conveyance on said carrier surface of said carrier, at least one aperture provided in said carrier surface near at least one of said lateral supports juxtapositioned to said deepened section of said carrier and said elevated part, beneath at least one edge area at a side of said stack of sheets accommodated in said holder, such that a partial vacuum can be produced by way of said at least one aperture beneath said sheets using a vacuum means, means for introducing and blowing air across said deepened section of said carrier against at least one side of said stack of sheets whereby an air layer is created between at least the bottom sheet in said stack of sheets and the remaining sheets in said stack so as to substantially separate said bottom sheet from said remaining sheets in said stack of sheets and a transport means for discharging said bottom sheet.
