Definitions

  • the invention relates to a circular weaving machine for producing a circular fabric, comprising: a main axis, a reed for guiding a shuttle for weft ribbons, a storage holder for warp ribbons, a feed device for drawing in the warp ribbons from the storage holder, the feed device having a first feed roller and a associated drive, an arrangement of guiding and length compensation elements for the drawn-in by the drawing-in device warp ribbons, a withdrawal device for withdrawing the round fabric made from the weft ribbons and the warp ribbons at a withdrawal speed.

  • AT 364 903 proposes a solution in which the lever of the thread tension compensating device is loaded by two springs to regulate the warp thread tension, with one spring over the entire pivoting range of the lever, the other spring only is effective over part of this pivoting range.
  • a single transport roller is provided, which is driven at a peripheral speed that is greater than the required warp thread speed in the circular loom. The warp thread is guided around the transport roller over an angle of wrap of more than 90°.
  • the transport roller is covered on its circumference with a material that has a high coefficient of friction.
  • the tension of the warp thread With the tension of the warp thread, the frictional grip of the warp thread on the transport roller increases, so that the warp thread is transported at a higher circumferential speed than the fabric take-off speed. With a low tension, on the other hand, the transport roller slips, so that the warp thread is fed more slowly to a subsequent, non-driven guide roller. If the warp thread is fed in slowly, the tension of the warp thread in the dynamic weaving process gradually increases, so that the frictional connection between the warp thread and the transport roller increases again and the slippage decreases. In this way, the tension of the warp thread is already regulated before the thread tension compensation device, with which changes in tension due to shedding and weft insertion are compensated for.
  • a certain amount of compensation can be achieved with the leading transport roller system from AT 364 903, but the transport roller must be provided with a coating that has a high coefficient of friction.
