Abstract (en)

A procedure for locking the torsion of shafts in long spinning frames, said procedure comprising: - start-up of the spinning frame with the device (20) for locking torsion connected up; - the disconnecting of said devices (20) after a pre-set time long enough to cover the initial transient period; - re-connection of the device (20) for a long enough time before the spinning frame is stopped; - the device (20) is kept connected up while the spinning frame remains halted so as to ensure the proper working of said spinning frame when it is next started up again and so as to avoid phase displacement of the cylinders. The invention also concerns the device (20) for carrying out said procedure and for locking the torsion of the shafts in long spinning frames, said device (20) being characterized by including in cooperation and coordination: - transmission means (16) connected rigidly to a powered shaft (10) of the spinning frame. - drivable coupling means (21) connected to said transmission means (16) and cooperating temporarily with at least one other shaft (11) of the spinning frame, and - control means (22) able to operate said drivable coupling means (21) so as to suit the speed of said powered shaft (10).
