Abstract (en)
[origin: EP0351672A1] The bearing pressure exerted onto the roller (1) during the winding of a bobbin (2) is controlled by means of a control device in which the roller (1) is mounted on a balance arm (6). The deviation of the balance arm (6) from its desired position is determined by a sensor (13) and converted in a controller (14) into a correcting movement of an adjusting device (17). The adjusting device (17) is a spindle drive having a spindle nut (18) and a spindle (20), the motor (21) of which is controlled by the controller (14). By means of the control device, which is designed as an automatic control sytem, the bearing pressure can be maintained very exactly during the entire winding operataion irrespective of the specific weight of the bobbin (2). <IMAGE>
