Definitions

  • the invention relates to a cross-wound bobbin according to the preamble of claim 1 and a method for the production thereof according to the preamble of claim 4.
  • Cross wound coils can be made with a true winding, with precision winding or with stepped precision winding.
  • cross-wound bobbin also includes the bobbin that builds up during winding of the cross-wound bobbin.
  • a step precision winding is a combination of winding and precision winding that exploits the advantages of both types of winding and avoids the disadvantages. It is a precision winding in steps made, for example, in which a maximum allowable crossing angle is set, which is smaller within a stage at a constant winding ratio. If the crossing angle reaches a smallest permissible level, the crossing angle is abruptly returned to the initial value. The turns ratio jumps to a smaller value. This results in a cheese with an approximately constant crossing angle, wherein the turns ratio has been reduced in stages.
  • a known problem in the production of cheeses of all three types of winding is the increased density at the flanks of the cheeses. Since the thread at the reversal point can not be stored acute-angled, but always in a radius is created, it comes at the edges of the cheese to a density increase, which causes a "bulging" of the edges. These because of the higher density “hard” edges are for optimum packing density and for a subsequent dyeing process of the cheese from disadvantage.
  • Another way to improve the density distribution of the coil is the targeted reduction of the laying width.
  • the DE 100 21 963 A1 describes the so-called breathing when winding threads in "wild winding".
  • the length of the traverse stroke is changed periodically, wherein at the beginning of the respiratory cycle, the thread is deposited at a turning point at the outer edge of the cheese. So that after completion of the respiratory cycle, the thread is not stored at the circumference of the coil in the same place, the speed and the traverse stroke of the traversing yarn guide is controlled so that the thread is after completion of the respiratory cycle at a reversal point offset to the reversal point at the beginning of the respiratory cycle.
  • the generic DE 43 10 905 A1 describes a thread laying for producing a cross-wound bobbin, in which the laying width in each case after passing through the thread by two reversal points, ie after a double stroke of traversing movement, is changed by new turning points are determined.
  • the accumulation of density at the edge of the cross-wound bobbin can be reduced and the density distribution evened far into the interior of the bobbin, so that with optimal setting the cheeses can be produced with a substantially homogeneous density distribution.
  • the precision or the step precision winding is often preferred in the manufacture of cheeses instead of the "wild winding".
  • By optimizing the selection of the turns ratios it is possible to influence the thread placement purposefully in this type of winding.
  • the excellent visual appearance of the yarn layers and the technological properties of such a cheese can be kept the same over the entire coil travel in very narrow limits, which is not possible with a "wild winding".
  • the invention has for its object to improve the construction of cheeses with precision winding or step precision winding.
  • the advantageous density distribution is not reduced. Rather, it was surprisingly found that due to the Windungsart precision winding or step precision winding and additionally by undisturbed production of the yarn layers both the absolute density of the cheese increases and improves their homogeneity.
  • the characteristic visual impression and the advantageous technological properties of the precision winding such as, for example, excellent running properties, good optics and high packing density, are unrestricted.
  • the new thread sections in the resulting gaps a particularly high density and homogeneity of the cheese can be achieved.
  • a swivel thread guide allows a favorable distribution of the masses to be moved and high traversing speeds with precise control of the thread laying.
  • the cheese 2 is driven by a rotating in the direction of arrow 4 friction roller 3.
  • the cross-wound bobbin 2 is held in a pivotable creel 5 and rests on the friction roller 3.
  • the thread 6 is supplied in the direction of arrow 7.
  • the thread 6 passes through the axis of the cheese 2 reciprocating yarn guide 8 and is wound onto the cheese 2.
  • the drive of the yarn guide 8 by means of the traversing device 9.
  • the friction roller 3 is driven via the shaft 10 by means of the motor 11.
  • the traversing device 9 is connected via the operative connection 12 to the motor 13. Both the engine 11 and the engine 13 are controlled by the microprocessor 14.
  • the microprocessor 14 includes a program for controlling the laying distance of the thread 6 in dependence on the actual diameter of the cheese 2.
  • the current diameter of the cheese 2 is calculated from the accumulated on the cheese 2 thread length.
  • the thread length is determined by means of the sensor 15, which detects the revolutions of the friction roller 3.
  • the sensor 16 is used to detect the rotational speed of the cheese 2, which is like the sensor 15 connected to the microprocessor 14.
  • the measuring head 17 detects the diameter of the running thread 6 and is also connected to the microprocessor 14.
  • FIG. 2 shows a winding unit with a pivotable thread guide.
  • Whose winding device 18 supports the cross-wound bobbin 20 by means of the coil frame 19.
  • the driven cross-wound bobbin 20 lies with its surface on a pressure roller 21 and takes this unpowered pressure roller 21 by means of friction with.
  • the drive of the cross-wound bobbin 20 via a variable speed drive means 22.
  • the traversing device 24 is provided for traversing the thread 23 during the winding process.
  • the traversing device 24 comprises a finger-like, pivotable yarn guide 25, which, by a electromechanical drive applied to the thread 23, as in FIG. 2 indicated, traversed between the two end faces of the cheese 20.
  • the thread 23 slides during its laying by the yarn guide 25 on a guide rule 26.
  • the control of the winding device 18 and the traversing device 24 by means of a microprocessor 27 via the lines 28 and 29.
  • Such a traversing device, as in FIG. 2 is shown, for example, in the DE 198 58 548 A1 or parallel to it US Pat. 6,311,919 described in detail.
  • FIG. 3 In FIG. 3 is shown a Garnlage a Rezisionsbewicklung without edge laying. Since the thread offset in the direction of the coil axis, that is, the distance between two adjacent, parallel threads is significantly greater than the diameter of the threads, it is called an "open" Rezisionsbewicklung. For better recognizability of the yarn layer 32 produced in open Rezisionsbewicklung is in FIG. 3 only this situation was shown separately and has been dispensed with the representation of the remaining cross-wound bobbin. This kind of representation becomes for the same reason also with the FIGS. 4 to 12 applied.
  • FIG. 5 provides a Garnlage 34 in open recuperzisionsbewicklung and FIG. 6 a Garnlage 35 in closed recuperzisionsbewicklung, where each conventional edge laying was made.
  • FIG. 11 shows a highly simplified representation of some exemplary yarn layers in the edge region on the bobbin surface of a cross-wound bobbin.
  • the width of the laying or traverse stroke over the coil width B SP of the in the representation of FIG. 11 left flank 39 of the cheese to the right flank 40.
  • the reversal points 41, 42 and the storage points of the thread of the lower yarn layer 38 are changed for the overlying yarn layer 43.
  • the yarn layer 43 has the reversal points 44 and 45 and has a smaller width B red than the underlying yarn layer 38.
  • the yarn layer 46 again has the same width, namely the coil width B SP , as the yarn layer 38.
  • the yarn layer 46 is followed by the yarn layer 47 whose width B red is reduced again.
  • the width B red of the yarn layer 47 is slightly greater than the width B red of the yarn layer 43.
  • a yarn layer 48 with the package width B SP is again placed on the yarn layer 47, etc. While every second yarn layer has the package width B SP , the width is B red varies the respectively intermediate yarn layers.
  • FIG. 12 shows three closed yarn layers, of which the wound on the lowest closed yarn layer yarn layers each have a smaller width B red .
  • the yarn layer on the in the representation of the FIG. 12 top yarn layer is wound may again have the coil width B SP . However, this additional yarn layer is not shown, so that the gradation of the three yarn layers produced by the Hubverminderung remains visible.
  • FIG. 13 shows from the multitude of rhombuses, as shown for example in the illustration of FIG. 7 can be seen, a single rhombus 49, in each case only the thread sections 50 of the thread 6, 23 are shown, which form the rhombus 49.
  • the thread sections 51 become as in FIG FIG. 14 shown misplaced.
  • the thread sections 51 have the laying distance v to the nearest thread sections 50 and run parallel to these.
  • further thread sections 51a are laid in parallel and at the laying distance v to the respective previously deposited thread sections 51, 51a.
  • the thread 6,23 is in the thread sections 50, 51 and 51a and in the rest FIGS. 13 to 18 shown as a line, which is the position of the center line of the thread 6, 23 can be seen.
  • the line thickness does not represent the true-to-scale diameter of the thread 6, 23.
  • the laying distance v is, taking into account the diameter of the thread 6, 23 chosen so that an "open" Rezisionsbewicklung and that the distance between the respective parallel thread sections 50 by the laying distance v is integer divisible. If in addition to the thread sections 50, 51 more thread sections 51a so are stored, that the next thread section 51a would be stored on or beyond the thread section 50 addition, the rhombus 49 is closed. There is a closed yarn layer in open recuperzisionsbewicklung.
  • FIG. 15 and FIG. 16 An alternative formation of yarn layers is in FIG. 15 and FIG. 16 shown.
  • the Indian FIG. 15 shown laying distance v between the thread sections 50 and the nearest thread section 52a and each between the subsequently stored thread sections 52a is taking into account the diameter of the thread 6, 23 chosen so that an "open" Retriel. If the last filed thread section 52 only so little spaced from the nearest thread section 50, namely with the distance v m that the next thread section 52a would be stored on or beyond the thread section 50 addition, there is a backward stroke.
  • the thread sections 52b are each returned to a laying distance v filed to each other. If a thread section 52b is only so slightly spaced from the thread section 50 that the next thread section 52b would be deposited on or beyond the thread section 50, a backward stroke takes place again. Subsequent to the backward stroke further thread sections, not shown here for reasons of simplification, are deposited until the last deposited thread sections are only spaced apart from the thread section 50 by the distance v m . Thus, the rhombus 49 is closed again and now a change in the laying width of the traversing movement is made on the return stroke. There are yarn layers in open recuperzisionsbewicklung on which then the next yarn layers can be stored.

If the thread section 53 only so little spaced from the thread section 50, namely with the distance v m that the next thread section 53 a would be stored on or beyond the thread section 50 out, there is a backward stroke. Subsequent to the backward stroke, the thread sections 53b are each deposited centrally between the thread sections 53a. Is the last filed thread section 53b only so little spaced from the thread section 50 that the next
