Definitions

  • the invention relates to a cylindrical cheese and a method for forming the winding body of a cylindrical cheese with a thread guide according to the preamble of claims 1 and 7.
  • Yarn produced on rotor spinning machines differs from the ring spun yarn in the structure of the package and in the flow behavior.
  • the rotor yarn is less hairy than the ring spun yarn and is therefore easier to unwind (easier lift off), but has a greater tendency to curl than the ring spun yarn, so that the wound yarn is pushed outwards in the edge region of the cheese from the overlying yarn layers.
  • This can form beyond the normal spool stroke of, for example, 150 mm, grown up to a width of 170 to 180 mm cross-wound bobbin. In such a case, a desired coil structure with flat faces no longer comes off.
  • Such phenomena occur with yarns of natural fibers such as cotton, especially coarse yarns, and are the more pronounced the coarser the yarn is.
  • the decreasing crossing angle with increasing cross-wound bobbin diameter limits the maximum allowable Diameter in the production of precision spools from staple fiber yarns, especially since staple fiber yarns can not be wound with arbitrarily small crossing angles in order to avoid the defects occurring at the edges. For this reason, as described for example in the generic DE 100 15 933 A1, crossing angles of less than 28 ° should be avoided in rotor spinning. As a result, the precision winding, in particular when winding staple fiber yarns, only very limited useful.
  • step precision winding an approximately uniform crossing angle over the coil travel is sought. Also, with the step precision winding, the above-described density problems or problems with the stability of the coil edge in practice only slightly reduced, but not resolved.
  • the compressive strength of the bobbin in the predetermined friction zone is slightly increased.
  • the cause for forming a drive zone with higher specific pressure of the resting on the drive roller coil by changing the crosshairs angle is given only by the different coil circumferential lengths in conical cheeses.
  • New machine techniques especially in weaving, such as air jet looms, place increased demands on the running properties of the yarn.
  • the requirements can not or insufficiently meet with the known coil designs.
  • the invention has for its object to provide a comparison with known cylindrical cheeses improved cylindrical cheese and a method for their preparation on rotor spinning machines, especially when producing coarse yarns to create.
  • the object is achieved by a method according to claim 1 and a cylindrical cross-wound bobbin according to claim 7.
  • the invention is based on the recognition that, compared to the crossing angle in the middle part of larger crossing angles in the edge region of the cheese, the crossing angle in the remaining wider middle part clearly compared to usual Crossing angles can be reduced without having to take the disadvantages occurring in a reduction of the crossing angle over the entire winding width disadvantages.
  • the reduction of the crossing angle can be driven considerably far without leading to an inadmissible hardening of the cross-wound bobbin.
  • the invention leads to an improved sequence of the thread of the cylindrical cheese.
  • the thread run is quieter, counteracts looping and Garnverhakungen and thus allows higher yarn withdrawal speeds.
  • the coil structure, in particular at the end faces of the cylindrical cross-wound bobbin, is improved.
  • the run length of the yarn at the same bobbin diameter is significantly increased compared to a conventional cylindrical cheese of the same winding type.
  • crossing angle ⁇ advantageously increases steadily from the crossing angle ⁇ M of the central zone to the crossing angle ⁇ R of the edge zone.
  • the edge zones can be dimensioned such that they occupy no more than 15% of the total winding width B WG .
  • a respectively made with increasing coil diameter reduction of the coil contact pressure according to claim 5 and a reduction of the thread tension according to claim 6 ensures the suppression of an undesirably high Garnpressung according to the invention crossing angles ⁇ , which are smaller than 28 ° are.
  • the coil contact pressure is known to be composed of the weight of the coil and the weight of the coil frame and the force resulting from the torque applied by, for example, a torque transducer. The coil contact pressure can be reduced so that not only the coil weight is compensated, but beyond discharge occurs.
  • a reciprocating thread guide for example a belt thread guide
  • the method according to the invention for producing a cylindrical cross-wound bobbin according to the invention can be carried out without additional structural complexity and without replacement Of thread guide elements by the corresponding device or programming the controller in a simple manner.
  • the invention makes it possible to wind even coarse yarns with relatively low crossing angles. For example, the processing of cotton yarn with Nm 20 at a crossing angle ⁇ of 25 ° with the associated good flow properties and long run lengths still possible. Improved drainage characteristics reduce downtime by reducing the number of thread breaks during further processing of the bobbins. With the run length becoming larger as a result of the reduction in the crossing angle, it is possible to wind up a yarn quantity increased by about 15% to 25% compared to a conventional cylindrical cheese with the same bobbin diameter on a cylindrical cheese according to the invention. this leads to a significant reduction in the number of cheeses in a lot. This not only reduces downtime for the bobbin change at the spinning stations, but also the transport costs and the transport volume during bobbin transport are reduced. The cost of handling the cheeses in subsequent yarn processing processes can be reduced.
  • the invention improves productivity and makes it possible to reduce costs and thus to increase overall economy in yarn production and processing.
  • FIG. 1 shows a winding device 1 at a spinning station of a rotor spinning machine producing a cylindrical cross-wound bobbin.
  • the winding device 1 has a roller 2, which drives the cylindrical cheese 3 by means of friction.
  • the roller 2 rotates in the direction of arrow 4.
  • Die Cheese 3 is supported by a pivotable creel 5 and rests on the roller 2.

  • the yarn guide 11 is part of a traversing device 13 which is connected via an operative connection 14 with the motor 15 and driven by this.
  • the roller 2 is driven via the shaft 16 by a motor 17.
  • Both the motor 15 and the motor 17 are controlled by a microprocessor 18, wherein the crossing angle ⁇ of the cylindrical cheese 3, depending on the position of the yarn guide 11, is controllable during the respective Spulenhubes.
  • the cylindrical cross-wound bobbin 3 shown in FIG. 2 shows a wound body 12 wound onto the bobbin tube 19.
  • the bobbin 12 has a cross-winding with the crossing angle ⁇ R in the edge zones 20, 21 and a cross-winding with the crossing angle ⁇ M in the middle zone 22 on.
  • ⁇ R in the exemplary embodiment of FIG. 2 is 35 ° and ⁇ M is 25 °.
  • the width of the zone 22 and the edge zones 20, 21 are each marked by a dashed line.
  • the cylindrical bobbin 12 is shown in a simplified schematic diagram, the respective course of the laid thread 6 is only partially indicated, but can be different degrees of crossing ⁇ detect.
  • the width B WG of the cheese 3 from the left spool edge 23 to the right spool edge 24 is in the embodiment 150 mm.
  • the width B WG corresponds to a stroke of the yarn guide 11.
  • Figure 3 is the actual Forming the crossing angle ⁇ of the cheese 3 or the thread pattern on the lateral surfaces closer than the representation of Figure 2.
  • Figure 3 shows the as Curve 31 over the winding width B WG of the cheese 3 illustrated course of the size of the crossing angle ⁇ , the values of the stroke of the yarn guide 11 in the representation of the cylindrical cheese 3 of Figure 2 from left to right (Hub of the thread guide 11 during the forward movement) represent.
  • the width of the middle zone 22, in which the crossing angle ⁇ is at the value of ⁇ M 25 °, occupies the major part of the winding width B WG .
  • the course of the size of the crossing angle ⁇ during the stroke of the yarn guide 11 in the return movement to the left is indicated by dashed lines in Figure 3.
