Definitions

  • the present invention relates to a textile machine for producing roving with at least one solidifying agent by means of which a roving having a protective rotation can be produced from a fiber structure fed to the solidifying agent, and with a winding device arranged downstream of the solidifying agent in a transport direction of the roving for winding up the solidifying agent prepared roving on a drivable by means of a sleeve drive sleeve.
  • a method for operating a corresponding textile machine is proposed.
  • Roving is produced from slivers pretreated (eg doubled) with the aid of stretching and serves as a template for the subsequent spinning process in which the individual fibers of the roving are spun into a fiber yarn, for example with the aid of a ring spinning machine.
  • a drafting system which is usually part of the corresponding textile machine, and then to provide it with a protective rotation.
  • the said strength is important to prevent ripping of the roving when winding on a sleeve or during the supply to the downstream spinning machine.
  • the given protective rotation must on the one hand be so strong that a cohesion of the individual fibers is ensured during the individual winding or unwinding operations as well as corresponding transport processes between the respective machine types. On the other hand, it must be ensured despite the protective rotation that the roving can be further processed in a spinning machine - the roving must therefore continue to be delayable.
  • flyers In order to produce a corresponding roving, so-called flyers are primarily used, but their delivery speed is limited due to centrifugal forces occurring. Therefore, there were already many suggestions to bypass the flyer or to replace it with an alternative machine type (see for example EP 0 375 242 A2 . DE 32 37 989 C2 ).
  • the solidification of the unconsolidated fiber structure described therein is effected by means of a solidifying agent, which causes no rotation, but a spiral wrapping of a sliver by one or more filament yarns, preferably monofilament filament yarns, which hold together the fiber structure and give it its strength.
  • the spirals of the individual filament yarns can be arranged in the same direction or in opposite directions. Preference is given to two filament yarns, which are arranged in opposite directions or cross over.
  • the roving produced in this way is thus essentially composed of a sliver of parallelized staple fibers and one or more fine-denier filament yarns spirally wound around the sliver.
  • the filament yarn may be applied to small diameter small coils.
  • the filament yarn is then pulled off the stationary bobbin and pulled through the bobbin axis along with the fiber strand, the filament yarn being wound around the fiber web and the number of turns drawn from the bobbin corresponding to the number of turns applied to the fiber web.
  • the binding point should be determined by a suitable thread guide.
  • Another method for producing roving describes the WO 2009/086646 A1 the method comprising the steps of: 1) providing a fiber strand in the form of two, preferably untwisted, fiber ribbons, 2) imparting S and Z turns over alternating regions of the two fiber ribbons, with regions of S and Z turns 3) merging the two provided with S and Z turns fiber slivers into a roving, wherein the two slivers automatically spin together due to their tendency to reverse.
  • the S and Z rotations can z. B. by means of two elements of the used solidifying agent, which hold the respective sliver clamping, at least one element, preferably both elements, the sliver by a relative movement on its surface transverse to the sliver longitudinal direction on both sides alternately impart opposing rotations. At the same time, the respective sliver is moved in sliver direction.
  • the S and Z rotations can also be generated by means of an aerodynamic, in particular pneumatic, process.
  • the alternating S and Z turns are also interrupted by changing areas without rotation.
  • the two slivers provided in the same way with S and Z turns are finally brought together in the so-called merging point.
  • the slivers begin to spin automatically, ie they wrap around each other. This so-called fraen maintains the S and Z turns in the individual slivers, so that a self-stabilizing two-component roving arises.
  • the regions without rotation in the first sliver should be arranged offset to the regions without rotation in the second sliver in the longitudinal direction, so that never two areas without rotation of the first and second sliver in the resulting roving adjacent to each other, as the Strength of the roving essential of the phase position the areas depends without rotation of the two slivers.
  • the rovings are therefore, as described above, always brought together with the aid of the solidifying agent so that their areas are out of phase without rotation.
  • the roving produced in this way finally has a higher strength compared to a non-twisted fiber composite, which is finally sufficient to wind the roving without misalignments on a spool and unwind from this again

  • said assembly comprises means by which the roving between the solidifying agent and the suction port during start-up of the roving can be brought into contact with the sleeve during ongoing roving production (i.e., with active, roving-producing solidifying agent).
  • mechanically or pneumatically operating devices can be used, which allow movement of the roving in the direction of the sleeve and thereby cause the necessary for the start of the winding operation contact between roving and sleeve (wherein the sleeve has a contact portion with a plurality of prongs may have, which fix the roving to the sleeve surface).
  • the said arrangement comprises means by which the roving can be severed while the roving is being produced such that the portion of the roving covered by the suction unit can be removed by means of the suction unit and the portion of the roving running between the consolidating agent and the sleeve can be wound onto the sleeve , As described in more detail below, this is a separate separation unit, which is moved into the barrel of the roving.

  • the separation unit may comprise a separation arm which is pivoted or otherwise moved into the run of the roving. It is crucial that the roving comes into contact with the separation arm or a separating element thereof. This creates a friction between roving and separation arm or separator, which causes a short-term or abrupt braking of the roving. If the roving has already been caught by the rotating sleeve, it is braked before being wound onto the sleeve.
  • the resulting tensile stress finally causes a severing or ripping of the roving in the region of the separating element, so that the suction unit side roving (ie, the roving section which extends into the interior of the suction unit after severing or tearing the roving) is sucked off the suction unit and the solidifying agent-side roving can be (further) wound on the sleeve, wherein the solidifying agent-side roving extends between the solidifying agent and the sleeve.

  • the starting process can also be carried out particularly reliably since the delivery speed of the solidifying agent does not have to be increased or only insignificantly increased after the starting process.
  • the circumferential speed of the sleeve is regulated such that the section of the roving running between the consolidating agent and the sleeve is at least partly sagging due to gravity. It is thus of advantage if the said section, in particular the section of the traversing unit which leads between the solidifying agent or the withdrawal unit (if present) and the sleeve or the roving, is only exposed to the tensile stress which is caused by the own weight of the corresponding roving section , This can be monitored for example by one or more sensors that monitor the slack of the roving in said area.
