ABSTRACT:
A method of feeding porous sheets from a stack is provided in which one or more air outlet nozzles and one or more air inlet nozzles are positioned in a pick-up position proximate a first sheet of the stack, a flow of air from the outlet nozzle(s) sufficient to penetrate the first sheet is generated so that a cushion of air is generated between the first sheet and a second sheet of the stack so as to lift the first sheet from the second sheet, a flow of air into the inlet nozzle(s) is generated so that the lifted first sheet is drawn against a pick-up surface defined by the inlet nozzle, and the inlet and outlet nozzles are reciprocally displaced between the pick-up position and a feed position in which a feed mechanism engages the first sheet.
