Definitions

  • a wire mesh for a densifier of a spinning machine such as the disclosures EP 1 783 253 A2 and DE 103 25 385 A1 is known, has a fabric of intersecting filaments and is provided at least in a fiber transport region of the wire mesh with open spaces between the filaments to allow a suction air to act on a fiber bundle moved thereon.
  • the Siebriemchen is an elementary component of a compacting device in compact or compaction spinning machines. After passing through a conventional drafting system with a pair of output rollers, a stretched fiber bundle is taken from the wire mesh after leaving the pair of output rollers and transported by means of the driven Siebriemchens via a stationary suction slot. Vacuum acts on the fiber bundle through the suction slot and compacts it into a compact body. Projecting fibers are applied to the fiber bundle. Since the suction slot is usually inclined to the direction of movement of the wire mesh, a lateral relative movement of the fiber bundle is forced over the surface of the wire mesh. The fiber bundle curls up during this movement - it creates a false twist. In addition to the purely pneumatic compression thus an additional, mechanical compression is achieved.
  • the sieve strap prevents suction of fibers during compaction and guides the fibers over the suction slot.
  • the Siebriemchens drive, for example, by a top roller with rubber cover, which presses the Siebriemchen against the surface of the compression device or against a suction tube and thus converts the rotational movement of the pressure roller in a revolution of the Siebriemchens.
  • By pressing the Siebriemchens is subject to the stationary compression device wear on the bottom of the sieve, which determines the life of the sieve in most applications.
  • the fabric of the wire mesh made of filaments has a certain resistance to displacement, which is determined by the bending and tensile strength of the filament and the weave of the fabric. If the resistance to displacement of the wire mesh is insufficient, the fabric may shift due to the friction between the wire mesh and the compacting device which fluctuates across the width of the wire mesh, resulting in lateral drainage of the wire mesh or even wrinkling.
  • Object of the present invention is therefore to be able to achieve the best possible yarn quality with a wear-resistant Siebriemchen as possible.
  • An inventive wire mesh is provided for a compacting device of a spinning machine, in particular a compacting or compact spinning machine.
  • the wire mesh has a fabric of intersecting filaments, in particular of monofilaments.
  • the wire mesh is designed such that in a fiber transport region of the wire mesh a fiber bundle can be picked up by the wire mesh and transported together with the wire mesh to a delivery point of the fiber bundle.
  • the fiber transport region is seen transversely to the transport direction of the wire mesh, the region in which a fiber bundle, which is taken from the pair of output roller of the upstream drafting received on the Siebriemchen and discharged again at the discharge point, or in other words, the area that the fiber bundle by its relative movement transverse to the longitudinal direction of the Siebriemchens travels on the Siebriemchen.
  • the fiber transport area is thus not defined solely by the transport movement of the fiber bundle. Because the fiber bundle usually also performs a relative movement transversely to the direction of movement of the wire mesh, the fiber transport region is also defined in terms of its width.
  • the lateral boundary of the fiber transport region usually results from a suction slot, which is arranged in a suction tube below the wire mesh.
  • the Siebriemchen has open spaces between the filaments. According to an advantageous embodiment, it is perforated with a defined free area of at least 10%. This means that at least 10% of the Siebriemchens in the fiber transport area are permeable to air for acting below the Siebriemchens Saug Kunststoffstrom.
  • the remaining surface of the wire mesh consists of the filaments of the fabric and is not used to aspirate the fiber bundle moved on the wire mesh, but to restrain the fibers of the fiber bundle, so that they are not sucked into the suction.
  • the suction slot can be arranged either parallel to the direction of movement of the wire mesh or inclined thereto in the suction pipe.
  • the suction pipe also serves to guide the wire mesh as well as a mating surface for a driven roller which moves the wire mesh.
  • the Siebriemchen is usually endless. That is, the sieve strap forms a ring which is placed around the guide or the suction tube and constantly transports the incoming fiber bundle.
  • the bumps typically present in the intersections of the filaments of the fabric are in the practice of this invention the Siebriemchens leveled.
  • the Siebriemchens leveled.
  • a relative movement taking place, in particular, transversely to the direction of movement of the wire mesh can be carried out with less resistance. This can be a better yarn created and beyond the wear of Siebriemchens be reduced.
  • the flattened intersections of the filaments and rounded edges of the filaments and the open spaces are provided either only on the upper side of the wire mesh.
  • the yarn formation is advantageously influenced in particular.
  • both on the top and on the underside of the Siebriemchens leveled intersections of the filaments and rounded edges of the filaments and the open spaces are provided.
  • a particularly advantageous influence on the wear of the Siebriemchens to take It is particularly advantageous if the upper side and lower side of the wire mesh are differently leveled and / or rounded. As a result, the respective, different requirements of the two sides of the wire mesh can be addressed.
  • the Siebriemchen is exposed on the underside in particular a friction against the storage and deflection of Siebriemchens. A related relatively large wear is the result.
  • the top side of the wire mesh must be able to interact particularly well with the fibers moving and transported on it. So it may be advantageous that the underside of Siebriemchens less severely flattened crossing points than the top of Siebriemchens.
  • the edges of the filaments and / or the open spaces may also need to be on the underside of the wire mesh not or only slightly rounded, since there are no transverse movements, but only a support on the bearing or deflection of the wire mesh and thus a flat contact exists.
  • the leveled intersections of a new wire mesh effect a bearing ratio of more than 10%.
  • the fibers rest on more than 10% of the surface of the wire mesh or that the wire mesh rests on more than 10% of its surface on its underside, for example on the suction pipe.
  • the surface pressure is reduced, which has a positive effect on the wear of the wire mesh.
  • the support share at the top of the wire mesh is higher than at the bottom of the wire mesh or the support portion at the bottom of the wire mesh is smaller than at the top of the wire mesh, an improved surface with respect to the coefficient of friction is advantageously created. Adhesion-induced friction is reduced due to the smaller contact area.
  • the ratio of the sum of the areas of the leveled intersection points to the difference of the total area minus the free area is between 0.1 and 0.8.
  • the leveled intersection points form surfaces on which the fibers contact the wire mesh or the wire mesh interacts with the bearing and deflection guide points.
  • the sum of the areas of the entered crossing points is divided by the total area of the wire mesh or the fiber transport area, from which the free area of the wire mesh or the fiber transport area is subtracted. This quotient gives a value between 0.1 and 0.8. In a particularly advantageous embodiment, this value is approximately between when in contact with the intake manifold 0.2 and 0.3. Compared to the elastic fibers, it is advantageous if this value is greater than 0.3.
  • the wire mesh itself if the leveled intersections of the wire mesh Filaments and the rounded edges of the filaments and / or the free surfaces are provided both in the fiber transport region and in the edge regions of the wire mesh. There may be zones in which the surface of the filaments is not flattened at the intersections and other zones in which it is flattened. Also, the flattening on the top and on the bottom can be provided differently or completely omitted in some areas.
  • the complete Siebriemchen be provided only at the top or on the top and bottom with flattened filaments at the intersection.
  • there is also a flattening, which faces the adjacent filament of the fabric within the plane of the fabric this is harmless, but an effect on the movement, in particular the relative movement of the fiber bundle or the wear of the wire mesh is only slight ,
  • the surface of the wire mesh is at least in the fiber transport area by a machining, in particular by grinding, or leveled or calendered by means of a roller.
  • the originally provided with a round surface Filaments of the tissue are removed in the region of the crossing points, so that a flattened surface is formed.
  • the surface of the filaments is at least thermally leveled in the fiber transport region, in particular by means of an ultrasound sonotrode, then this causes by means of a heat action that the cross sections of the filaments are changed in particular in the region of the intersection points and the tissue thus has a flattened surface. Due to the thermal effect on the filaments not only the humps of the intersections are leveled, but also rounded at the same time.
  • the filaments used in the fabric are profiled.
  • filaments are used which have a non-round profile already during their production or a corresponding post-processing prior to the production of the fabric.
  • the profile is such that it has at least one flattened surface in the cross section of the filament.
  • the profiled filaments preferably have a flattened, in particular oval or elliptical or substantially rectangular cross section.
  • a flattened cross-section can be produced which, when used appropriately in the fabric of the wire mesh, leads to a flattened surface of the fabric and thus of the wire mesh.
  • Aspect ratios of about 1 to 2, for example about 80x150 microns are advantageous.
  • the filaments have a diameter between 30 .mu.m and 400 .mu.m. As a result, fine and coarse fiber bundles can be processed. In a particularly preferred embodiment the filaments have a diameter between 80 ⁇ m and 300 ⁇ m. These cross-sectional diameters provide the best compromise between good yarn production and a wear-resistant wire bond.
  • the fabric of the wire mesh is woven from filaments of different diameters. It is advantageous that different diameters of the filaments are used in warp and weft. As a result, the size and shape of the intersection points cause different areas of the leveled intersections. These can have a positive effect in particular on the transverse movement of the fiber bundle on the surface of the wire mesh.
  • the fabric is woven with a 1/1 canvas or twill weave. This means that the chain and the end change sides at each intersection.
  • twill weaves such as 1/2, may also be used, the 1/1 weave or twill weave has been found to be particularly advantageous for the fabric of the wire stitch in conjunction with the present invention.

  • a sufficiently strong suction force is generated on the fiber bundle, which it pressed against the wire mesh and on the other hand, but also still allows the relative movement of the fiber bundle.
  • the filaments are fused together at least in the fiber transport region at the intersection of the fabric and / or pressed and / or connected to each other by means of a positive connection.
  • the wire mesh is provided with a coating, in particular with a polymer, at least at the points of intersection of the filaments, a rounding of the flattened filaments and the mesh openings or open areas of the fabric takes place in a particularly advantageous manner.

  • the coating can be applied before and / or after the leveling of the intersections of the filaments.
  • the filaments are fused or glued together at the edge regions of the wire mesh in order to avoid fraying of the wire mesh.
