Abstract
A sheet handling apparatus includes a sheet transport path, a pinch and drive mechanism disposed at an entry side of the transport path for conveying the sheets in a transport direction X along the transport path, at least one liftable pinch and drive mechanism disposed at the transport path downstream of said entry side pinch and drive mechanism, a sheet alignment mechanism disposed further downstream at the transport path and arranged to impart a movement in a direction Z normal to the transport direction X to at least a part of a sheet that passes through, and a controller arranged to receive a sheet length signal and to control said at least one liftable pinch and drive mechanism in accordance with the sheet length.

A sheet handling apparatus comprising:
- a sheet transport path;
- a pinch and drive mechanism disposed at an entry side of the transport path for conveying the sheets in a transport direction X along the transport path;
- at least one liftable pinch and drive mechanism disposed at the transport path downstream of said entry side pinch and drive mechanism;
- a sheet alignment mechanism disposed further downstream at the transport path and arranged to impart a movement in a direction Z normal to the transport direction X to at least a part of a sheet that passes through;
- and
- a controller arranged to receive a sheet length signal and to control said at least one liftable pinch and drive mechanism in accordance with the sheet length, characterized in that the controller is arranged to disable the sheet alignment mechanism when the sheet length is larger than a predetermined threshold.
