Vorrichtung zum Verschwenken einer Walze für eine laufende Bahn

摘要

The invention relates to a device (5) for pivoting a roller (4) for a moving web (15). Said device comprises a shaft (6) which traverses the roller (4) and has gears (7, 8) provided at the ends thereof (9, 12). A servo-actuator (10) engages on the gear (7) and turns the shaft (6) and displaces the end (9) thereof. The gear (9) on the opposite end (12) of the roller (6) changes the rotating movement of the shaft (6) into an opposing propulsion movement of the opposite end (12) with the result that the shaft (6) is pivoted by the single servo-actuator (10) about its central point (13). The roller (4) is rotatably mounted on the shaft (6) and is pivoted therewith.
