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.
Claims15
An apparatus for the corrective position of a travelling web (18, 20) at right angles to the direction of travel (B'), comprising at least one tilting roll (1, 45, 46)
- over which the web (18, 20), to be correctively positioned transversely, is guided at an angle of contact (U),
- said at least one tilting roll having a rotating sleeve (2) and a sleeve pipe, said rotating sleeve (2) supported on said sleeve pipe by two rotary bearings,
- at two ends of the sleeve pipe, said sleeve pipe being (5, 5', 5", 35) non-rotatable relative to the axis of rotation (R) of the roll sleeve (2),
- said sleeve pipe (5, 5', 5", 35) being symmetrically articulated by pendulum-joint elements (7, 8), the pendulum-joint elements (7, 8) being stationarily disposed diametrically opposite to the at least one tilting roll (1) and at a radial distance from the axis of rotation (R), and are in common defining an oblique tilting axis (Q), which intersects the axis of rotation (R) in the center of gravity (W) of the at least one tilting roll, forming an acute angle (A), and which runs in a plane (X) that cooperates with a vertical plane (Y) situated at right angles to the direction of travel (B') to enclose an acute angle (B) thereby opening in the direction of travel (B').
