Definitions

  • the present invention relates to a spinning preparation machine having at least one solidifying agent for producing a protective rotation roving from a fiber dressing supplied to the solidifying agent, with a drafting device upstream of the consolidating agent in a running direction of the roving for stretching the fiber composite before entering it into the solidifying agent, with a Solidifying agent in the said direction downstream winding device for winding the roving on a sleeve, and arranged in the region of the winding device and movably mounted traversing element for guiding the roving during winding onto the sleeve, wherein the solidifying agent in a side view of the spinning preparation machine in the vertical direction between at least one input roller of the drafting system and arranged in the vertical direction below the traversing element is arranged.
  • 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 were used in the past, but their delivery speed due to occurring Centrifugal forces is limited. Therefore, there were already many suggestions to bypass the flyer or replace it with an alternative machine type.
  • 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 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 next to each other, since the strength of the roving depends significantly on the phase position of the areas 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 ultimately sufficient to wind the roving without Freundververs on a spool and unwind from this again.
  • the spinning preparation machines should still be easily accessible to perform particular repair and adjustment work or necessary troubleshooting after an unwanted stop the Vorgarnher too can.
  • EP375242 discloses a device for producing a roving according to the preamble of claim 1.
  • JPS5530798U and JPS5526053U reveal air spinning machines.
  • WO2005026421 and DE102012102695 disclosed a roving machine for making a roving.
