Abstract
A regulator (4) works with a thread or yarn supply which is intended to provide a draw-out length of the thread or the yarn which is dependent on the one hand on the size of the supply and on the other hand on an assumed or adjusted thread tension in the draw-out thread or the draw-out yarn. A load cell (7) is arranged so as to sense the actual thread tension in the drawn-out thread and to supply to the regulator (4) information (i1) for changing the size of the thread stock when the actual thread tension deviates from the assumed or previously adjusted thread tension (the desired value). The load cell can also function as a pick monitor.
Claims9
Arrangement for a regulator (4) which works with a thread or yarn supply (4a, 4b, 4c and 4d) which is intended to provide a draw-out length (L) of the thread which is dependent on the one hand on the size of the supply and on the other hand on an assumed thread or yarn tension (that is to say a desired value) in the draw-out thread (6a), characterized by one or both of the following alternatives:
- a) a load cell (7) is arranged so as to sense the actual thread tension in the drawn-out thread (6a) and to supply to the regulator (4) information (i1) for changing the size of the thread stock when the actual thread tension deviates from the assumed or adjusted thread tension, that is to say the desired tension value,
- b) the load cell is arranged so as to supply pick-monitoring information by means of which the load cell indicates that there is a fault or discontinuity on the thread or the yarn and/or that the gripping function is not operating etc.
Arrangement according to any one of the preceding patent claims, characterized in that the load cell (7) is arranged at the exit of the regulator for thread or yarn delivery.
Arrangement according to any one of the preceding patent claims, characterized in that each load cell is connected to the control unit (15) of the machine, which senses the information signal (i1) of the load cell and supplies a control signal (i2) depending on the sensing to the supply-adjusting means of the regulator.
