ABSTRACT:
A stalled roll registration device that minimizes or prevents creasing of a sheet as it is fed through the device. The rolls that register the sheet are not perfectly cylindrical and have a larger radius toward the outside edges of the sheetpath. After the sheet is stalled and then started through the registration pair, the velocity difference caused by the noncylindrical rolls causes the edges of the sheet to be urged toward the edges of the sheetpath thereby minimizing the risk of wrinkling the sheet.
