ABSTRACT:
A device whereby sheets can be discharged one by one from the bottom of a stack of sheets provided in a holder having a base support and side supports wherein in the transverse direction of sheet transport the base support surface has a downward bent shape so that the support surface has a deepened part on its supporting side such that in the proximity of the deepened part, beneath at least an edge zone of one side of a stack of sheets to be accommodated, the support surface is provided with at least one opening in which a vacuum can be created so that the bottom sheet is sucked against the support and air is blown against the side of the stack as considered with respect to the direction of sheet transport, in order to create an air layer at least between the bottom sheet and the stack thereabove, the airflow being ejected in the proximity of the deepened part of the support surface.
