ABSTRACT:
A device for conveying and positioning sheets, comprising positioning apparatus for positioning one of the longitudinal sides of the sheets on the ideal transport line for said longitudinal side, the positioning apparatus being adapted to occupy an operative or an inoperative position, and actuating apparatus for moving the positioning apparatus, the positioning apparatus comprising a first conveying device and a second conveying device, each comprising two conveying members, at least one of which is formed by a roller, which two conveying members can form a transport nip extending parallel to the ideal transport line, the transport nip of the first conveying device extending along the ideal transport line and the second conveying device being situated at some distance from the first conveying device in the zone of the sheet conveying path, and drive apparatus are provided by which the roller (or rollers) of each conveying device can be so driven that each conveying device in its operative position exerts on the sheets a force which is directed towards the other conveying device. The effect of this is that one of the longitudinal sides of a sheet is positioned on the ideal transport line for the longitudinal side irrespective of whether the sheet is fed diverging to either side from the ideal transport line, the lateral abutment being formed by the transport nip of the first conveying device.
