Abstract

Abstract 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).

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 131 words
I. Procedure for locking the torsion of shafts in long spinning frames, said procedure being characterized by in- . cluding the following phases: . - start-up of the frame with the device (20) for locking torsion connected up; the disconnecting of said device (20) for locking torsion after a pre-set long enough time (T I ); - re-connection of the device (20) for locking torsion for a long enough time (T 2 ) before the spinning frame is stop- . ped; . - the device (20) for locking torsion is kept connected up . - while the spinning frame is halted so as to ensure the pro- . per working of said frame when it is next started up once again and so as to avoid phase displacement of the cylinders.
Claim 2
Dependent Claim 38 words
. 2. Procedure as in Claim I, characterized by the fact. . that the disconnecting of the device (20) for locking torsion takes place after a time (T I ) long enough to cover the. initial transient period.
Claim 3
Dependent Claim 45 words
Procedure as in Claims I & 2, characterized by the. fact that the re-connection of the device (20) for locking. torsion lasts for a period (T 2 ) before the stopping of the. machine (T F ) long enough to cover the transient stopping period.
Claim 4
Dependent Claim 90 words
Device (20) to carry out said procedure and the locking of torsion of the shafts in long spinning frames, characterized by comprising in cooperation and coordination: .- transmission means (I6) connected riqidlg to a shaft (10). of the spinning frame, . .- drivable coupling means (2I) connected to said transmission means (I6) and cooperating temporarily with at least . one other shaft (II) of the spinning frame, and - control means (22) able to actuate said drivable coupling. means (21) so as to suit the speed of said shaft (10).
Claim 5
Dependent Claim 25 words
Device (20) for locking torsion as in Claim 4, characterized by the fact that said shaft (10) is the powered shaft of the spinning frame.
