Abstract: The web-motion controller comprises a guide frame (4) with two guide rollers (2.1, 2.2). The lateral deviation of the web 91) downstream of the second guide roller (2,.2) is monitored by a position sensor (8), whose output signal is converted into control commands for a servomotor (7) turning the guide frame (4). In the guide frame (4), between the guide rollers (2.1, 2.2) a braking roller (11) is provided which is wrapped and entrained by the web and has a braking device (12). A force-measuring drum (14) finding out the web traction after the braking roller (11) in the travel direction of the web serves for producing measured-value signals, which control the braking device (12) via a control unit (13) with a selected value setting (19).
