Abstract

A device (5) for swinging a roll (4) for a moving web (15) consists of a shaft (6) extending through the roll (4), with provision made for gearings (7, 8) on the ends of said shaft. A servo-drive (10) engages the gearing (7), putting the shaft (6) into rotation and displacing its end (9). Gearing (8) on the counter end (12) of the roll (4) translates the rotary motion of the shaft (6) into a motion of thrust of the counter end (12) in the opposite sense, so that shaft (6) is swiveled by the single servo-drive (10) around its central point (13). Roll (4) is rotatably supported on shaft (6) and is jointly swiveled with the latter (FIG. 1).
