Abstract
A method and a device for controlling a winder, where the winding torque (T.sub.w), during winding, is controlled as a function of the desired tractive force in the material to be wound. During winding, repeatedly is calculated which value a quantity (V.sub.l), influencing the winding torque (T.sub.w), has to adopt in order to obtain a desired tractive force (F.sub.w), and an adjustment of the said quantity (V.sub.1) is carried out, the calculated value being used as an objective value. Preferably, the calculation is done by an algorithm, expressing the said quantity as a function of the desired tractive force (F.sub.w), as a function of one or more fixed parameters which are characteristic for winding up material or for the winder, and as a function of one or more variable parameters, being measured or calculated during winding. The device also relates to a winder comprising a winding body (1), (2) for winding a material, a drive device (3,9),(4,10) for driving this winding body (1), (2) an a control device.
