<p>A device by means of which sheets can be discharged one by one from the bottom of a stack from a holder, provided with a carrier and lateral supports. The carrier (1) has a downwardly bent shape transversely of the direction of conveyance of the sheets so that on its carrying side the carrier has a deepened part. In the vicinity of the deepened part, beneath at least one edge zone of a side of a stack of sheets to be accommodated in the holder, the carrier is formed with at least one aperture (10) in which a partial vacuum can be produced so that the bottom sheet is sucked against the carrier. The deepened part of the carrier (1) extending transversely of the direction of conveyance is provided with at least one elevated part (30) on the carrying side. Means are also provided to blow air against the side - as considered with respect to the direction of conveyance of the sheets - of the stack in order to produce a layer of air at least between the bottom sheet and the stack there above, said means being so disposed that the air stream is blown out in the vicinity of the deepened part of the carrier (1). The friction between the sheet which is to be discharged and the stack there above is thus reduced. At the instant that the air layer has formed between the bottom sheet and the stack there above the sheet is discharged through the agency of a transport means (16). <IMAGE></p> |
