Definitions

  • the invention relates to a thread delivery device, the especially for the positive delivery of threads to textile machines can be used.
  • the individual thread consumption points of a textile machine threads to be delivered may depend on the used material, the twist, the thread thickness and other characteristics very different properties have, which also appear on the thread delivery device to step.
  • Thread delivery devices are said to usually deliver several or all of the threads mentioned can without causing any difficulties. Problems can arise here with threads that dust, that have filaments protruding from the thread which are relative carry a lot of sizing with you or in any other way Traces or deposits on parts of the thread delivery device leave or cause. River deposits that are especially on the thread delivery wheel of a thread delivery device can lead to impairments of the thread run and the thread delivery and in extreme cases to tear the Thread.
  • a yarn delivery device is included a rotating and driven thread delivery wheel known that by a provided with several cone areas Thread storage drum is formed.
  • the diameter of the on the thread entry area lying thread turns decreases in the axial direction of the relatively long thread inlet area.
  • the incoming thread pushes the in the entry areas already lying turns in the axial direction, so that these migrate towards the storage area, whereby the thread tension in the individual turns can change.
  • the thread properties influence this process.
  • DE 3326099 C2 is a thread delivery device known that also a rotatably mounted, has a rotationally driven thread delivery wheel.
  • the thread delivery wheel has one by two adjoining Cones define a thread inlet area and one itself adjoining it, in one embodiment cylindrical Thread storage area.
  • the thread delivery wheel can be constructed in one or more parts. From the same Publication is also known, the thread inlet area and / or the thread storage area with recesses to provide only an interrupted edition of the To bring about thread in these areas.
  • the storage drum in each embodiment points to its lower, a disc-shaped end remote from the thread inlet area Flange that extends in the radial direction.
  • Thread delivery device with a thread delivery wheel known a tapered entrance area, one such as a cylindrical thread storage area and a thread outlet area has, which by a kind of Pulley-formed section is formed.
  • a conical Transition area in the Transition from the storage area to the pulley-like trained section there is a conical Transition area.
  • the thread storage area is one groove-shaped groove formed around the circumference, which separate the thread storage area from each other separate investment areas divided.
  • the thread delivery wheel has a relatively complicated Shape up.
  • Taiwanese utility model with the publication number 314077 is a thread delivery device with known a rotationally symmetrical thread delivery wheel that is integrally formed and a thread inlet area and a thread storage area and a thread outlet area having.
  • the thread entry area follows with convex Curvature an annular section of a torus, while the thread storage area is approximately cylindrical is. Following the thread storage area takes the diameter of the thread feed wheel gradually increases, so that a conical area with a cone angle of results in a few degrees.

  • the Ribs are held at the end of end plates.
  • the winding feed on the thread delivery wheel that passes through The incoming thread is caused on the narrow one Ribs in the thread entry area limited.
  • Threads and wraps different. differences exist in particular between smooth threads and threads with Filaments where single turns on filaments are adjacent turns and can clamp them. However, the usability of thread delivery devices is said to be out understandable reason not limited to certain threads his.
  • This task is done with a thread delivery device after Claim 1 solved.
  • the thread delivery wheel of the thread delivery device can be wear-resistant Have surface that on a less hard carrier, for example. A metal body is applied or it can consist entirely of the substances mentioned. there the thread delivery wheel is preferably formed in one piece, which enables inexpensive production.
  • the Thread delivery wheel is preferably in its thread inlet area, in its storage area and in its thread outlet area formed without through openings, so that it surrounds a closed interior.
  • the storage area is preferably a substantially closed sheet trained in the need, even smaller, of the thread support areas spaced openings provided could be. Lint or other deposits can build up then do not get stuck in openings covered by the thread and disrupt the thread flow.
  • the abrasion resistance prevents the formation of grooves or steps or others Wear marks that in the long run the proper Operation, especially the smooth feed of the Can interfere with the winding.
  • the thread delivery wheel with ceramic surface has it also proved to be advantageous, the thread inlet area and the thread outlet area as a closed surface preferably with a circular cross section at each point train.

  • the protruding edges can concave or sectionally concave and convex his.
  • Such a design prevents the deposits continuous river rings or larger river plug in Recesses, with the support of the thread wrap on individual edge areas of the thread section concentrated remains. This facilitates the axial displacement of the winding, so that this also with different threads or Yarns can be moved in a controlled manner. Even if the Support areas are somewhat worked off, are the conditions not fundamentally changed and the thread delivery device works reliably. This applies in particular to thread delivery wheels, whose surface is not made of a fabric Claim 1 exists. The geometry mentioned is for different Suitable threads (yarns). By the edition of the Winding in the storage area only in strip-shaped Support areas will in particular be the delivery of threads relieved with many filaments.
  • the ceramic or another of the above Hard materials existing or coated with this thread delivery wheel can be made in one piece, which enables the entire area covered by the thread train seamlessly. This allows the thread to move freely run and there is hardly any risk that he might be at a Groove remains hanging.
  • the thread advantageously touches the surface of the thread delivery wheel in the thread inlet area continuously and is guided so that the thread outlet area from the Thread is stripped. This is done by ordering the Thread outlet eyelet or a corresponding guide element reached, its arrangement at a radial distance Axis of rotation of the thread delivery wheel and below one of the bottom edge set the thread also in the transition from the storage area to the run-out area until the thread delivery wheel rests until it is itself finally separates from the wrap.
