A winder for winding a band of fabric or knitting or the like on a roller, particularly for circular knitting machines, comprising a frame which supports a takeup roller and a traction roller, which is supported by the frame and can be actuated with a rotary motion about its own axis with respect to the frame, the traction roller making contact with the takeup roller, with the interposition of the band wound around the takeup roller, the traction roller being arranged so that its axis is above the axis of the takeup roller and can move toward or away from the axis of the takeup roller as the winding diameter of the band on the takeup roller varies, the winder comprising elements for the actuation of the traction roller with a rotary motion about its own axis with a substantially constant actuation torque. |
