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: An aligner (46) is positionable adjacent a sheet stacking bin (i.e. 14) to engage sheets fed to the bin and drive them to reference edge (32A). The aligner comprises a rotatable shaft (52) carrying resilient radial flaps. The flaps are of a size such that sheets fed to the bins are both edge and surface engaged by the flaps. Preferably, the slots between the flaps are arranged such that they are positioned in a helix round the shaft.
