DEFINITION

Classification: 271/135

(under subclass 133) Device wherein the means acts on the lowermost sheet and moves that lowermost sheet in its own plane to pre-feed or to individualize that lowermost sheet prior to the action of the reciprocating feed member in fully separating the sheet from the stack.

(1) Note. Included herein a device wherein a pusher having steps simultaneously engages a plurality of sheets to push those sheets in repeated increments along the feed direction until the lowermost sheet is fully ejected, as well as a device in which the lowermost sheet is partially moved in a direction other than the feed direction so that it will be subsequently engaged by the reciprocating feed member.
