Title: Sheet skew removing device
Inventor: KONRAD J BELL
IPC: B65H27/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent a sheet from being damaged and an aligning edge guide member from being worn and damaged excessively in a sheet skew removing and aligning device. SOLUTION: This sheet skew removing and aligning device 150 is provided with an aligning edge guide member which forms a surface in parallel to a processing direction, a skew removing roll 100 with at least one flexible rib, which drives a sheet horizontally to the processing direction in order to conduct exact arrangement and alignment of the sheet by pressing the sheet against the aligning edge guide member 102. The skew removing roll 100 with a flexible rib involves a flexible rib 120 in a series of non-axial direction, and grooves 127 which are disposed alternately with adjacent ribs.  When the sheet 101 which is driven by the rib is brought into contact with the aligning edge guide member 102 and receives resistance, the respective ribs can deflect so as to decrease the driving force of the skew removing roll 100 applied to the sheet 101, thus it is possible to prevent the aligning edge guide member 102 from being worn and damaged excessively as well as the sheet 101 from being worn and damaged.
