Definitions

  • the invention relates to a Kammgarnitur for a rotatable about an axis of rotation Kämmwalze a textile machine, in particular a combing machine and in particular for a circular comb.
  • Combers are known from the CH 673 290 A5 EP1, 533, 404A , and the DE 10 2007 010 405 A1 , Such combing machines have a cyclical sequence of their working cycle.
  • a tongs apparatus With a tongs apparatus, a tuft of a combing wadding is combed out by a combing field of a circumferential circular comb fitted with combing strips. Subsequently, unhismmek Kämmwatte is refilled and the pliers apparatus moves to trigger cylinder. As a result, the combed tuft is placed on the previously combed Kämmwatte, connected to this and peeled off.
  • a top comb ensures that unkorn fibers and impurities that are not placed on the combed cotton wool are combed out or held back. Thereafter, the replenished Kämmwatte is combed out, thus a new Kämmzyklus, which is also called Kammspiel begins.
  • a circular comb includes one Worktop, which is arranged perpendicular to a rotation axis of the circular comb on a combing roller.
  • the combed clothing has a plurality of comb segments arranged one behind the other in the direction of rotation of the combing roller.
  • each comb segment has a plurality of axially juxtaposed sawtooth stamped parts with a foot part and extending from the foot part teeth, wherein the configuration of the teeth of the comb set changes in the direction of rotation in order to influence a combing effect achieved thereby.
  • Such combs are from the DE 43 26 205 C1 and from the EP 1 083 250 B1 known, wherein a worsted next to an engagement comb segment comprises a plurality of follower comb segments, each of which produces a higher combing effect than the previous following comb segment or the engagement comb segment.
  • the EP 1 341 952 B1 further shows a comb set for a combing roll, wherein the configuration of teeth of the worsted against the direction of rotation changes such that the combing effect increases.
  • the combing result is improved, but on the other hand, yarn defects of the further processed fiber material can not be ruled out.
  • a combed clothing is known, which at least partially pinstripes, which are attached to a support member.
  • a comb assembly comprises at least a first and a second comb segment region, wherein a configuration of teeth within the first comb segment region changes such that a combing action of the teeth against a rotational direction increases and the teeth within the second comb segment region are configured such that the combing effect within the second comb segment region is smaller than at the end of the first comb segment region opposite to the direction of rotation.
  • At least one of the configuration measures of increasing the tooth height, increasing a free passage between two adjacent teeth in the direction of the rotation axis, increasing a tooth spacing between two adjacent teeth in the rotational direction, reducing a meshing angle and reducing a peak density is provided to those compared to the end of first comb segment region to achieve reduced combing effect within the second comb segment region.
  • the combing action of the teeth within the second comb segment region is selectively adjustable.
  • a change of a configuration of the teeth takes place at a predetermined location.
  • the second comb segment region can also comprise a plurality of comb segments.
  • a comb segment according to claim 6 may have different combing effects of the teeth in different comb segment areas.
  • toothless intermediate discs according to claim 13 enables a targeted adjustment of the free passage between axially adjacent teeth and also the number of teeth provided in the axial direction.
  • the two comb segment regions 2, 3 are arranged one behind the other in a direction of rotation 4 of a combing roller, not shown, and by in the direction of a rotation axis 4a of the combing unit 1 of a circular comb of a textile combing machine
  • the lined sawtooth punches 5 are axially, spaced from one another positionable. These washers are optional.
  • the steelge leopardstanzmaschine 5 can also be arranged axially adjacent to each other immediately.
  • the sawtooth stamped parts can also have shoulder embossments in the axial direction, so that the sawtooth stamped parts, despite an adjoining arrangement, have intermediate distances in the axial direction.
  • the first comb segment region 2 comprises four comb segments 8; However, it is also conceivable that the first comb segment region 2 has more or less than four comb segments 8, but at least one comb segment 8.
  • the second comb segment region 3, as shown in FIG Fig. 1 exactly one comb segment 8; However, it is also conceivable that the second comb segment region 3 comprises a plurality of comb segments 8.
  • the comb segment 8 is also referred to as a bolt, wherein the bolt of the second comb segment region 3 is referred to as the end bolt, since it is arranged in the direction of rotation 4 at the end 9 of the combed clothing 1.
  • the intervention of the circular comb takes place in the material to be combed.
  • the comb segment 8 arranged at the beginning 10 is therefore also referred to as an engagement comb segment.
  • the intervention of the circular comb in a Kämmwatte and the subsequent rotation of the circular comb in the direction of rotation 4 represent the combing.
  • the direction of rotation 4 is therefore also referred to as Kämmraum and the effect caused thereby on the Kämmwatte as Kämmrial.
  • the first comb segment region 2 has a configuration of the teeth 7 such that the combing action of the teeth 7 increases counter to the direction of rotation 4.
  • the increase in the combing effect of the teeth 7 is achieved by configuration measures, which will be explained below.
  • the teeth 7 are within the second comb segment region 3 configured such that the combing effect within the second comb segment region 3 is on average less than at one seen in the direction of rotation 4 end 11 of the first comb segment region 2.

It is also possible that a change in the configuration of the teeth takes place at a different location within at least one of the two comb segment regions 2, 3.
  • the worsted fabric 1 is fastened with the foot parts 6 of the comb segments 8 on the combing roll.
  • each foot part 6, a connecting element 13, which cooperates in each case with a complementary thereto formed connecting element of the combing roller.
  • the connecting elements 13 may be formed as bores, in particular as through-holes, but also as grooves, in particular as dovetail-shaped grooves.
  • the Kammgarnitur 1 may be glued to the Kämmwalze 8 with the foot parts 6 of the comb segments.
  • Fig. 1 illustrated worsted with the five comb segments 8 extends over a clothing circumference angle of 111 °, since this, in particular for the combing of cotton, has proved advantageous.
  • this clothing circumference angle allows to improve the manufacturing accuracy of the comb segments 8, each having an identical segment circumferential angle W, so that the foot portions 6 of the comb segments 8 are identical.
  • the comb segments can also have differently sized foot parts with different segment circumferential angles W. It is also conceivable Kämmgarituren with clothing circumferential angles of 78 °, 87 °, 90 °, 98 ° and 112 °.
  • For combing virgin wool or blends with synthetic fibers These are used or other clothing circumferential angle depending on a machine type. In this case, a clothing circumferential angle in a range of 145 ° -220 ° has been found to be particularly advantageous.
  • foot portions of comb segments may differ within a comb segment area.
  • a tooth height H is defined between a notional upper edge 14 of a foot region 6 and an outer envelope 15 of the tooth tips 16 of the teeth 7.

  • a free passage D is the free surface between two teeth 7 and two stakege leopardstanz tone 5, which are arranged axially adjacent within a comb segment 8 in the direction of the axis of rotation 4a of the combing roller. The free passage D is in Fig. 2 not shown, since it extends perpendicular to drawing plane.
  • a specific peak number Z also peak density Z, characterizes a portion of a cylindrical surface of the circular comb, which engages in the Kämmwatte, on the entire cylinder surface area, which is predetermined by the envelope 15.
  • the peak density Z thus results both from the tooth spacing T measured in the circumferential direction and an axial tooth spacing measured along the rotation axis 4a, which results from an expansion of the sawtooth punching part 5 in the axial direction, as well as from a thickness an intermediate disc which can be arranged between two sawing parts 5.
  • the peak density Z is therefore a surface-related quantity.
  • At least one of the configuration measures such as a reduction in the tooth height H, reduction of the free passage D between two adjacent teeth 7 in the direction of the rotation axis 4a, reduction of the tooth spacing T between two adjacent in the direction of rotation 4

  • the tooth height H and the tooth spacing T after a reduction compared to their values in the Endriegel within the first Kammsegment Symposium can be taken that the tooth height H and the tooth spacing T after a reduction compared to their values in the Endriegel within the first Kammsegment Symposiums an increase in the values in Endriegel at a circumferential angle at least 76.5 °.
  • the tooth height H in the end bar assumes the initial value of the tooth height H at the beginning of the worsted, after the value at the beginning of the end bar has been reduced by about 30% compared to the initial value.
  • the value of the tooth height H in the end bar can also be above or below the initial value.
  • the tooth spacing T is approximately doubled in the end bar in relation to a value at the end of the first comb segment area, counter to the direction of rotation, where a smallest value of the tooth spacing within the comb set is present.
  • the free passage D is not increased to reduce the meshing effect of the teeth within the end bar. D remains constant along the worsted pattern for the diagrams shown. It is also possible to make the free passage D variable along the Kammgarnitur by a large value for the free passage D is selected, for example, at the first bar at the beginning of the worsted. Contrary to the direction of rotation 4, the free passage D is then continuously reduced, wherein the free passage in the region of the end bar can also rise again.
  • the worsted fabric according to the invention exhibits an increased combing effect in the first comb segment area over known comb fabrics.
  • the increased combing action is based, in particular, on an increase in the tooth engagement angle E by about 20% to 50% and on an increase in the peak density Z of about 10% to 30% in comparison to the Kammgarnituren according to EP 1 083 250 B1 and the EP 1 341 952 B1 ,
  • this increased combing effect is made possible only by the subsequent reduction of the combing action in the end bar described above, which ensures a smooth transition of the material to be combed from the combing process to the subsequent soldering process. An unchanged high combing effect on the end bar would lead to errors in the soldering process and thus to faulty yarn.
  • the reduction of the combing action at the end bar of the worsted of the invention allows higher maximum values of the combing action within the first comb segment area compared to the prior art, so that the integral combing effect of the combed garniture according to the invention despite the reduced combing action on the end bar with the integral combing effects known from the prior art Kammgarnituren is comparable, but significantly higher speeds of the circular comb of, for example, more than 500 combing cycles per minute are possible. With appropriate design of the worsted of the invention, an integral combing effect can be achieved, which is greater than that of the known from the prior Kammgarnitur.
