Abstract: Sheet feed and aligning apparatus receives sheets fed in skewed orientation from a stack (18). A roller pair (46) initially advances the sheets without altering the skew angle, to further roller pairs (48, 56). As these pairs advance the sheet, sensors (68 and a further one, not shown) positioned along a line at an angle to the direction of sheet feed, sense its leading edge. In accordance with the timing of this sensing, drive means (42,46) for the further roller pairs are independently controlled to correct the skew.

Abstract: Documents fed serially from a document reproduction machine 10 are fed by a vacuum belt feed system 21 to sheet accumulation and stapling system 22. When at the registration position in system 22, the leading edge of each sheet has passed output bin 14, and the trailing portion is supported either by platform 16 or sheet sets thereon. After a set is accumulated in system 22, it is stapled and then ejected back into bin 14.
