Definitions

  • the invention relates to a cross-over peelable cross-wound bobbin and a method for their Het ein, in which at least one thread is wound with a variable during the winding pitch angle.
  • Cross-wound bobbins are supply bobbins, which can serve as a template for weaving or knitting machines in further processing. In contrast to disc coils they have a self-supporting cross-wound and have no end-side walls. A thread is wound helically with a relatively large pitch angle, so that the threads cross several times and the individual thread layers stabilize each other.
  • the rotational speed of the thread balloon forming at a constant withdrawal speed of the thread varies depending on the coil diameter and the direction of movement of the separation point of the thread from the cross-wound package.
  • the fluctuations in the rotational speed lead at certain diameters to a continuous folding of the thread balloon between a single and double balloon or between a double and triple balloon.
  • the folding of the thread balloon causes sudden changes in the thread tension and can thereby cause thread breaks.
  • the withdrawal speed is limited by these voltage spikes.
  • To reduce the thread tension fluctuations is from the WO 02/060800 A1 known to vary the pitch angle as a function of the laying direction.
  • the invention is based on the object to further improve the flow behavior of a cross-wound bobbin and at the same time to achieve an increase in the package density, or to increase the thread length stored in the cross-wound with the same outer dimensions.
  • EP 13 06 356 A1 is a winding of filament yarns to cheeses known in which the winding takes place with large pitch angles, wherein the pitch angles over the diameter of the cross-wound bobbin have different sizes.
  • the invention has for its object to further improve the flow behavior of a cross-wound bobbin and to achieve an increase in the package density, or to increase the thread length stored in the cross-wound with the same outer dimensions.
  • the rotational speed of the thread balloon and thus the thread tension is much higher than for large diameters. Therefore, variations in the orbital speed of the yarn balloon lead to yarn breaks particularly quickly and should therefore be as small as possible.
  • the smaller the pitch angle the smaller the fluctuation of the rotational speed from position to position. A smaller pitch angle thus leads to a better drainage behavior.
  • the package density increases. The extreme case is parallel turns.
  • the rotational speed of the yarn balloon is practically constant and the package density is maximum.
  • a uniform and relatively small pitch angle over the entire diameter range of the cross-wound bobbin has the disadvantage that the stability of the finished bobbin during handling is no longer guaranteed.
  • a sufficiently large pitch angle, in particular in the outer diameter range is required. Therefore, for an optimum coil construction, a rising from the inside outward pitch angle is particularly advantageous.
  • Equally advantageous for an optimal package construction is to introduce thread layers with parallel turns at certain intervals. These contribute to increasing the coil density, without they would have the disadvantage of a pure parallel winding, because the layers with parallel turns are enclosed by layers with a larger pitch angle, so that a snagging of the threads is effectively prevented.
  • the cheese wrapper It is advantageous to manufacture the cheese wrapper on a single-pass machine. By contrast, it is irrelevant whether it is wound, for example, from a yarn, a thread, a filament or even a double thread.
  • the definition of the pitch angle ⁇ is in FIG. 2 shown.
  • the vectors of the delivery speed v z and the traversing speed v v are plotted and show the relationship to the pitch angle ⁇ .
  • the pitch angle ⁇ can be influenced by changing the traversing speed v v .
  • the traversing yarn guide 5 is moved with the stroke H 1 in and against the laying direction V back and forth. With every movement along the stretch H 1 , a thread layer is created.
  • the thread 4 of the outermost, completely finished thread layer is denoted by 6.
  • the thread layer 6 extends from the reversal point 7 on the one coil side 8 to the second reversal point 9 on the other coil side 10.
  • the totality of all thread layers forms the cross-wound package 11 with the diameter D 1 and the width B.
  • the stroke H 1 is, except for one low Hubatmung, kept substantially constant, so that the width B of the resulting cross-winding 11 corresponds approximately to the stroke H 1 .
  • FIGS. 3 and 4 show the situation when overhead deduction of a cross-wound bobbin 1.
  • the thread 4 detaches from the cross-wound bobbin 11 at a separation point 12 and is withdrawn through the trigger eye 13 at a constant speed in the direction A.
  • the cross-wound bobbin 1 and the trigger eye 13 are fixed in space.
  • the thread 4 rotates in the direction W to the cross-wound roll 11 and the free thread piece between the detachment point 12 and trigger eye 13 forms the thread balloon 14, while the separation point 12 moves in the direction P along the cross-winding 11.
  • With decreasing diameter D 2 of the cross-winding 11 increases Angular velocity of the thread balloon 14 at.
  • the angular velocity influences the shape of the thread balloon 14. It determines if there is a sliding trigger, a single, double or triple balloon. Furthermore, it is known that the angular velocity depends on the direction of movement P of the detachment point 12.
  • FIG. 3 the situation is shown in which the separation point 12 moves in the direction P from the trigger eye 13 facing the head side 15 of the cross-winding 11 to the base 16.
  • FIG. 4 shows a view of the cross-wound bobbin 1, in which the separation point 12 moves toward P 'on the head side 15.
  • the withdrawn here thread layer 6 ' is the one thread layer be that directly below the in FIG. 3 pulled thread layer 6 was.
  • the diameter D 2 of the funnelwickei 11 is the same size, and thus the resultant of the diameter D 2 angular velocity would be equal.
  • the angular velocity of the thread balloon 14 in the in FIG. 3 displayed moment higher than in the situation after FIG. 4 , This is due to the fact that the thread balloon 14 by the movement of the separation point 12 in FIG. 3 increased.
  • the stabilizing influence of the bobbin tube 2 becomes clear.
  • the diameter D 3 of the cross-winding 11 is still relatively small and the supporting effect of the bobbin 2 is still relatively large.
  • D 1 as in FIG. 1 shown highly required that the cross-wound package 11 stabilizes itself.
  • the pitch angle ⁇ is a decisive measure. If the pitch angle a is too low, turns lying on the coil sides 8, 10 can slip off and form unwanted loose thread loops, the so-called strikers.
  • the supporting effect of the bobbin tube 2 can be advantageously exploited if one holds the pitch angle ⁇ small at the small diameter D 3 and thus increases the thread length stored in a thread layer. Only with a larger diameter D 1 and the pitch angle ⁇ is increased. As a result, the coil density or the wound thread length can be increased without sacrificing stability.
  • FIG. 6 shows a representation of a thread layer with parallel turns 17 on a cross-wound bobbin 1.
  • Parallel windings 17 can be particularly advantageous as protective windings for separating different series of yarn layers with reduced and shifted traversing stroke H 2 after FIG. 5 be used.
  • parallel windings 17 allow storing the maximum thread length in a thread layer and thus also increase the package density. To avoid beaters, the parallel windings 17 should only begin at a distance a from the coil side 8 or already end at a distance b in front of the coil side 10.
  • the pitch angle ⁇ is almost zero, thereby changing the angular velocity of the yarn balloon 14 when deducted depending on the direction of movement P of the separation point practically not.
  • the layer arrangement can advantageously be controlled in such a way that, in the case of overhead removal of the finished cross-wound bobbin 1, the detachment point 12 follows FIG. 3 moves when a thread layer with parallel turns 17 is withdrawn. The increase in the angular velocity of the thread balloon 14 can be further reduced.
