摘要

Device (1) for correcting the lateral position of a printed sheet (2) in a web-fed printing machine comprises a correcting roller (6) arranged downstream of a drier (4) and pivoting so that its moves on a circular path (49) having a larger radius (R) than the length of the correcting roller. The correcting roller is pivoted by a pivoting lever arrangement having a first pivoting lever (18) hinged to a first shaft journal (10) of the correcting roller and a second pivoting lever (26) hinged to a second shaft journal (12) of the correcting roller. Preferred Features: The first pivoting lever is connected to the first shaft journal via a first hinge (16) and to a fixed part (22) via a second hinge (20). The second pivoting lever is connected to the second shaft journal via a third hinge (24) and to the fixed part via a fourth hinge (28).
