Definitions

  • the invention relates to a device for loop spinning or twisting, which comprises a substantially vertical spindle and a balloon limiter arranged coaxially with the spindle for feeding the yarn to a sleeve mounted on the rotating spindle.
  • the device mentioned above is one of the variants of a device for loop spinning or twisting according to the patent specification EP 0 883 703 B1.
  • the balloon limiter which has the shape of a one-piece tube and has a lower end widening, is rotatably supported here and is operated in the same sense as the spindle. In operation, the fed yarn is forced by the centrifugal force to travel along its inner surface, from which it then passes directly to the sleeve attached to the rotating spindle by the action of the winding pull.
  • the yarn is also forced to rotate around the longitudinal axis of the spindle, so that when it transitions from the inner surface of the balloon limiter to the sleeve, it forms a rotating open loop immediately below the lower end of the balloon limiter rotates, which end is also referred to as the outlet end, this loop controlling the tension of the yarn, similar to the rotor of a ring spinning device or a twisting device.
  • this loop controlling the tension of the yarn, similar to the rotor of a ring spinning device or a twisting device.
  • its rotation should be braked.
  • Quality yarns can be produced at high speed on such a device.
  • increased friction between the rotating open loop and the boundary wall must be expected, which can also lead to mutual damage.
  • this fact can mean a limitation that has not been completely overcome, not even with the use of a boundary wall with a sliding surface, which results from the area of the first Contact with the yarn in the direction of its lower end from the longitudinal axis of the spindle (EP 0 933 454). It has also been found that any contact of the reversible arc of the rotating open loop with the boundary wall increases the tension of the yarn unfavorably.
  • the object of the invention is to design the device described above so that it enables the production of quality yarn with high processing speed without the above-mentioned restrictions.
  • the balloon limiter consists of an upper part which is driven in the same direction of rotation as the spindle, and a non-rotatable lower part which connects to it in a contactless manner, the lower part having a guide surface for the yarn, which on its inner side begins and ends on its lower face.
  • the working speed can be increased even further, as a result of the fact that the radial load on the rotatable upper part of the balloon limiter is smaller in comparison with the earlier one-piece balloon limiter, in such a way that the centrifugal force component, which is achieved by means of the rotating open loop in the one-piece rotatable balloon limiter has acted on the outlet end with full weight, and endeavored to deflect this outlet end from the longitudinal axis, is now, at least partially, absorbed by the non-rotatable lower part of the balloon limiter.

  • FIG. 2 shows a partial section from FIG. 1
  • FIG. 3 shows a partial view of another example of the device according to the invention.
  • Fig. 1 only one of the devices for loop spinning or twisting is shown. On a corresponding machine, a larger number of such devices can be provided as work locations on one or both of their longitudinal sides.
  • This device contains a drafting device for the sliver or roving, or a feed device for a multiple thread system, depending on whether it is a device for loop spinning or a device for loop twisting. From the point of view of the invention, these devices each contain a feed device 1 for the fiber material 2 intended for spinning or twisting. Below the feed device 1, which is shown in FIG.

  • the delivery device can be used ⁇ which is arranged for this purpose, for example, so that the lower exit roller takes the place of the yarn guide and this so completely replaced.
  • the spindle 4 is designed as a rotor of an electric motor 10 arranged on a spindle bank 11.
  • the spindle bench 11 extends over all work locations of the machine and, in order to form a new yarn winding 6, it is provided with a conventional program-controlled drive (not shown) for its increasing and decreasing movement in the direction of the double arrow 12.
  • the. Spindle of course, also in a known manner, can also be rotatably arranged in a similar spindle bank, its rotational movement being derived from a tangential belt which likewise extends over all work locations of the machine (not shown).
  • the balloon limiter 7 consists of an upper part 13 . and from a lower part 1_4 that connects to it without contact.
  • the upper part has, for example, the shape of a bell or bottle, this having a coherent surface 15 . for contact with the yarn P and is flared in the direction of the outlet end 16.

  • the guide surface 22 is alternatively bent in the direction of the longitudinal axis 9 of the balloon limiter 7, or the spindle 4, its smallest diameter A - measured in the plane perpendicular to the longitudinal axis 9 of the balloon limiter 7, or the spindle 4 - being smaller than the largest diameter B of the inner surface 15 of the upper part of the balloon limiter 7.

  • the centrifugal force acting on the rotating open loop Ps also expediently supports the transition of the yarn P via the guide surface 22 of the non-rotatable lower part 14 of the balloon limiter 7.
