    摘要： A device for conveying and positioning sheets, comprising posi­tioning means (35) for positioning one of the longitudinal sides of the sheets on the ideal transport line (A) for said longitudinal side, the positioning means (35) being adapted to occupy an operative or an inoperative position, and actuating means for moving the positioning means (35), the positioning means (35) comprising a first conveying device (74) and a second conveying device (73) each comprising two conveying members (82, 84; 81, 83) at least one of which is formed by a roller, which two conveying members (82, 84; 81, 83) can form a transport nip extending parallel to the ideal transport line (A), the transport nip of the first conveying device (74) extending on the ideal transport line (A) and the second conveying device (73) being situated at some distance from the first conveying device (74) in the zone of the sheet conveying path, and drive means are provided by which the roller (or rollers) of each conveying device (73, 74) can be so driven that each conveying device (73, 74) in its operative posi­tion exerts on the sheets a force which is directed towards the other conveying device (74, 73).
    The effect of this is that one of the longitudinal sides of a sheet is positioned on the ideal transport line (A) for said longitu­dinal side irrespective of whether the sheet is fed diverging to either side from the ideal transport line (A), the lateral abutment being formed by the transport nip of the first conveying device (74).
