Abstract

The present disclosure relates to paper handling machines, and in particular to cut paper handling machines such as reprographic copiers and printer machines. In such machines, cut sheets of paper usually must be advanced through nips of sheet handling apparatus formed by pinch rollers. For effective operation of such a sheet handling apparatus, the dimensional specifications and tolerances for such sheet handling nips are designed for sheet or paper thicknesses within a predetermined range.

PAPER CROSS-TRACK SMOOTHING DEVICE (Cont'd)

The present disclosure relates to paper handling machines, and in particular to cut paper handling machines such as reprographic copiers and printer machines. In such machines, cut sheets of paper usually must be advanced through nips of sheet handling apparatus formed by pinch rollers. For effective operation of such a sheet handling apparatus, the dimensional specifications and tolerances for such sheet handling nips are designed for sheet or paper thicknesses within a predetermined range.

Unfortunately, however, some of the cut sheets of paper being handled usually contain significant corrugation which undesirably increases the effective apparent thickness of the sheet where such corrugation occurs. Such undesirable corrugation can run front-to-back in an in-track direction relative to movement of the sheet through a nip, or it can run in the cross-track direction. In either case, the corrugation effectively increases the apparent thickness of the sheet, and thus can result in paper or sheet jams within the sheet handling nips.Whereas in-track corru...
