ABSTRACT:
An apparatus for the corrective positioning of a travelling web at right angles to the direction of travel comprises a tilting roll over which the web to be positioned is guided. At both ends of the roll, provision is made for rotary bearings, the respective opposite bearing member of which is articulated to a pendulum joint element. These two pendulum joints define an oblique tilting axis, which intersects the axis of rotation in the center of gravity of the roll and runs in a plane which cooperates with a vertical plane situated at right angles to the direction of travel to enclose an acute angle.
