Abstract
An apparatus for registering a sheet along a transport path, including a plurality of spaced apart sheet feeding nip sets of plural sheet feeding nips in the sheet transport path, the plural sheet feeding nips of the sheet feeding nip sets comprise plural drive wheels and plural mating idlers, steerable drive mechanism for changing the drive wheel to idler alignment to thereby transport the sheet along the paper path while imparting a lateral motion to the sheet as it is transported along the paper path.
Claims10
An apparatus for laterally positioning a sheet along a transport path, comprising:
- a plurality of spaced apart sheet feeding nip sets in said sheet transport path, each one of the sheet feeding nip sets comprise drive wheels and mating idlers,
- a steerable drive mechanism for changing the mating idlers drive wheels alignment to thereby transport the sheet along the paper path while imparting a lateral motion to the sheet as the sheet is transported along the paper path;
- and
- an entrance sheet feeding nip and an exit sheet feeding nip, said entrance sheet feeding nip and said exit sheet feeding nip having both drive wheels and mating idlers aligned parallel relative to each other.
(canceled)
A method of laterally positioning a sheet, consisting of:
- feeding said sheet into a first pinch nip having a first orientation;
- successively feeding said sheet into successive pinch nips having a second orientation in which the idlers of each successive nip are aligned to one another and are aligned differently than the idlers of the first pinch nip;
- feeding said sheet to a final pinch nip having said first orientation.
