ABSTRACT:
A sheet handling system comprising a sheet registration system having sheet registration nips and a receiving system for a sheet including a capturing point for engaging said sheet. Auxiliary nips are positioned between the sheet registration nips and the receiving station. The auxiliary nips are moveable between an open and closed position. A controller receives a signal indicative of the length of the sheet and sends a signal to the auxiliary nips to be in a sheet engaging position when the length of the sheet is less than the distance between the sheet feeding nips and the capturing point of the receiving station and be in an open position if the length of the sheet is greater than the distance between the sheet registration nips and the capturing point of the receiving station. In another embodiment, the auxiliary nips are maintained in their open position until the trailing edge of a sheet is about to leave the sheet registration nips, at which point the auxiliary nips are closed.
