Abstract

A gear train (1) pivoted (11) around its drive gear (3) rotates a drive roller (13) with increasing pressure until the top sheet of paper (15) is moved. The corner buckler (19) is moved around a pivot (25) under the paper tray to drive the buckler into the paper stack. A bottom roller (27) permits the drive roller to rotate when the tray is empty. To reduce the angular variation of the gear train, its pivot point may be lowered by positioning it to the side of the tray. The assembly adjusts automatically to correct feeding variations.
