<p>A device whereby sheets can be discharged one by one from the bottom of a stack of sheets from a holder provided with a carrier (1) and lateral supports (2, 5). The carrier (1) of the holder is sagged permanently transversely of the direction of sheet transport. In the vicinity of the deepest part the carrier (1) is provided with at least one aperture (10) beneath at least one edge zone of a side edge of a stack of sheets to be received, in which aperture (10) a partial vacuum can be created so that the bottom sheet is sucked against the carrier. Means are also provided to blow air against the side edge of the stack, as considered with respect to the direction of sheet transport, in order to create a layer of air at least between the bottom sheet and the stack thereabove, said means being so disposed that the air flow is blown out over the deepest part of the carrier (1). The friction between the sheet to be discharged and the stack thereabove is thus reduced. At the instant that the layer of air forms between the bottom sheet and the stack thereabove the sheet is discharged by a transport means (16).</p> |
