Abstract
Sheet-feeding apparatus in which documents having distinguishable sides are momentarily halted by transversely spaced rollers to examine the sheets for proper orientation. A high-speed gating roller directs properly oriented sheets along the normal feed path. Upon detecting an improperly oriented sheet, the gating roller is driven in a reverse direction to drive the sheet into an inversion pocket where it is inverted before being returned to the normal path. The feed members along the inversion path are driven at a greater speed than sheets along the normal path to return the inverted sheet to it proper position in the document stream.
