- the sawtooth punched parts 5 can also be arranged axially directly adjacent to one another.
- 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 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 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 Kammgarnitur 1 may be glued to the Kämmwalze 8 with the foot parts 6 of the comb segments.
- the combed clothing shown in Fig. 1 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 to be 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 different 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 °.
- 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.

The free passage D is not shown in Fig. 2, since it extends perpendicular to the plane of the drawing.
- 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.

It is also possible to configure the teeth 7 within the second comb segment region 3 in such a way that the combing action of the teeth 7 decreases counter to the direction of rotation 4. This is also possible if the second comb segment region 3 comprises only a single comb segment 8, that is, the combing effect within the comb segment 8 is achieved by a configuration of the teeth 7 changing in the direction of rotation 4.

- the teeth 7 are configured such that the tooth height Hl, the tooth pitch Tl, the tooth engagement angle El and the tip density Zl not shown are constant.
- the continuous transition from the parameters H1, T1, E1 and Z1 at an end of the first comb segment part 18 seen in the direction of rotation 4 to the end variables of the parameters H2, T2, E2 and Z2 at the end 20 takes place via a plurality of intermediate stages Hi, Ti, Ei and Zi, of which an intermediate stage in Fig.

- the meshing angle E has in Endriegel in about the same value as at the beginning of the worstge in the direction of rotation.
- the tooth engagement angle E can also be greater in the end lock, in particular 50% greater than the value at the beginning of the worsted in the direction of rotation.
- the peak density Z is reduced as shown in FIG. 10 in Endriegel to about 50% of the peak density at the end of the first comb segment region in the direction of rotation. Correspondingly, it can be seen from the diagrams in FIGS.
- the tooth height H and the tooth spacing T increase in the end bar at a circumferential angle of at least 76.5 ° after a reduction relative to their values in the end bar within the first comb segment area.
- 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 curves 23 of the parameters E, Z, H and T in FIGS. 7 to 10 further show that in the inventive worsted the parameters within the first comb segment are continuously changed along the clothing circumference angle, so that a continuous, harmonic transition of the Combination between the comb segments is guaranteed.
- the curve 21 of the known from the prior art Kammgarnitur a gradual or staircase-shaped course of the parameters by their sudden transitions between the comb segments.
- the worsted fabric according to the invention exhibits an increased combing effect in the first comb segment area compared to known comb fabrics.
- the increased combing action is based, in particular, on an increase of 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 fillets according to EP 1 083 250 B1 and EP 1 341 952 B 1.
- this increased combing effect is only possible by the subsequent, above-described reduction of the combing effect in the Endriegel, the smooth transition of the material to be combed from the
- Combing ensures 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 over 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.
