ABSTRACT:
An improved nip drive for sheet feeding apparatus having an oscillating vacuum feeder for feeding sheets seriatim along a travel path. The feeder oscillates between a first position adjacent to an entrance to the sheet travel path, where a sheet is tacked to the feeder, and a second position downstream thereof along the travel path. The improved nip drive is adjustably engageable with the feeder, at spaced locations transversely to such path, for advancing a sheet along the travel path while the feeder oscillates. The nip drive is effected by a flexible drive shaft operatively coupled to such nip drive.
