Abstract (en)
[origin: WO2010119214A1] According to the invention, at least one of the threads (F) is rotated by means of a spindle (3) and forms a balloon (6) around a can or a stationary cradle (7) containing an unwinding or winding system (12), (13), and wherein the thread (F) is guided over at least one of the sides of the balloon (6) by a radial channel (4 and/or 14) extending into an arm or a disc integrally rotated with the spindle (3). According to the invention: a balloon is formed (6) adopting a curvilinear path, without being wound onto a bunch; the thread is positively driven by two drive systems (1, 8) with controlled speeds (V1, V2), one upstream and the other one downstream from the balloon (6); outside the start and stop phases, the speed (V1 or V2) of at least one of the two thread (F) drive systems (1 or 8) is permanently adjusted to retain the diameter (D) of the balloon at a setpoint value or between two parameterized minimum/maximum values.
