Definitions
- the invention relates to a cover set for carding machines, with a plurality of teeth inserted into rows of teeth in a scraper belt, each with a tooth bridge and a first tooth limb projecting from one end of the tooth bridge with a first tooth tip and a second tooth limb projecting from the opposite end of the tooth bridge have a second tooth tip.
- DIN 64 108 describes the terms and sub-terms of scraper belts, from which the types of stitch emerge in particular. Diagonal stitching is used in particular for cover sets that are used on textile cards. This diagonal stitch is on page 2, section 2.2. the DIN 64108 explains.
- the 4-diagonal stitch or 6-diagonal stitch is mainly used for the diagonal stitch. In the case of 4 diagonal stitches, the second row of teeth is offset by 1/2 tip width compared to the first. The offset corresponds to the aisle width g l . In the case of the 6-point diagonal stitch, the second row of teeth is offset by 1/3 tip width in relation to the first. Also z. B. a combination of diagonal stitches, ie 4 and 6 alternately used alternately.
- European Patent Application No. 80 10 3579 (publication number 0041076) published on December 9, 1981 shows a trim set in which at least two teeth formed in succession in the carding direction by the scratch wires are laterally offset from the carding direction by a distance that is no more than the wire thickness of the scraper wire is such that the cover set has no free lanes.
- a cover set is described which prevents the formation of alleys by a suitable type of setting. Experience has shown that an increased separation of impurities takes place in the carding process, and an increased degree of parallelization can also be achieved.
- the invention seeks to remedy this.
- the invention as characterized in the claims, solves the problem of creating a cover set for carding machines, in which the offset of the teeth in the direction of fiber passage decreases, so that a funnel effect of the fitting is formed.
- Fig. 1 shows schematically a cross section through a scraper belt 20 with inserted teeth 24.
- the scraper belt is usually a laminated body made of different materials, eg. B. fabrics and plastics.
- the scraping tape 20, for example, is made up of three layers 21, 22, 23 which are glued together. Hooks made of wire, i.e. teeth 1, are inserted in the scraper belt.
- a respective tooth 24 has a tooth bridge 1, two tooth legs 25 and two tooth tips 2, 3. A distinction is made between the first tooth tip 2 and the second tooth tip 3.
- FIG. 3 shows a first embodiment of the lid set according to the invention in a representation according to DIN 64108.
- the view of the back of the scraper belt is shown, so the toothed webs 1 are visible.
- the Fig. Is the view of the front of the scraper belt.
- Deviating from the corresponding representation according to DIN 64 108 are for the sake of clarity only the tooth tips 2, 3 and not the tooth legs drawn.
- the direction of fiber travel is designated by F.
- the tooth tip located in the fiber passage direction F at the right end of a tooth bridge 1 is designated by the reference number 2 and the tooth tip located on the left relative thereto is designated by the reference number 3.
- the rows of teeth are generally designated by the reference number 4, as indicated in FIG. 3. 3 can be regarded as starting from a diagonal stitch.
- the tooth tips 2, 3 each determine straight lines which run at an oblique angle to the direction F of the fibers.
- tooth tips 2, 3 which follow one another in the fiber passage direction F determine a curve line.
- the tooth tips 2, 3 of successive rows of teeth 4 in the fiber passage direction F are offset from one another to a decreasing extent, such that the offset from row of teeth to row of teeth has a smaller dimension.
- the lane width determined by the offset is generally designated by g.
- the alley width g is indicated in particular as an example, which is determined by first tooth tips 2 arranged one behind the other in the fiber passage direction F according to the inventive concept. It can clearly be seen that this aisle width g becomes smaller from row to row.
- the curve line C can be in a coordinate system x; Draw y, where x runs in the direction of the machine width and y in the direction of the cover width of the cover set, whereby the zero point 0 coincides with the lower left corner of the cover.
- the slope of this curve line C is increasing. It can follow different mathematical relationships in the specified coordinate system.
- This curve line C follows the relationship according to one embodiment a need not be an integer. As a result, the alley width g becomes smaller and smaller with increasing y and tends towards zero. Obviously, values that give g ⁇ 0 are meaningless because the alley width g can only be a positive number.
- a further embodiment of the setting type according to FIGS. 3 and 4 is limited to the section of the curve line C used in each case.
- the lid width is a measure given by a finite number, i.e. y [cm].
- the utilized section of the curve line C can be a section with a small slope or also a section with a high slope of the curve line C.
- the leading edge of the cover, seen in the fiber passage direction F, is designated 0% and the trailing edge is 100% cover width, the center is designated 50%, as shown in FIG. 3.
- the section of the curve line C between 0% and 50% lid width obeys the relationship Ay ⁇ Ax.
- the tangent T placed on the curve line C has an inclination angle of 45 ° or a tangent of 1.
- the section of the curve line C between 50% and 100% lid width obeys the relationship Ay ⁇ Ax.
- first and subsequent tooth rows 4 are offset from one another in groups with respect to the first and second tooth tips of tooth rows 4 preceding in the fiber passage direction F to an extent decreasing in the fiber passage direction F.
- the design is based on the rib stitch, here for example a 5 rib stitch.
- Three groups are shown one behind the other in the fiber passage direction F, groups 5, 6 and 7.
- Group 5 has an aisle width g 1 ' corresponding to its offset
- group 6 an aisle width g 2 corresponding to its offset
- group 7 an aisle width g corresponding to its offset 3 on.
- the tooth tips 2 of the leading group 5 determine a straight line 8, that of the group 6 a straight line 9 and that of the group 7 a straight line 10.
- All toothed webs 1 have the same Length and only for the sake of clarity only the straight lines determined by the second tooth tips 2 on the right are drawn.
- the straight line 9 has a greater slope than the straight line 8, and the straight line 10 in turn has a greater slope than the straight line 9.
- the slope of the respective straight line 8, 9, 10 is based on the slope angle a, ⁇ 1 of the straight line 8: x °, ⁇ 2 of the straight line 9: (x + y) °, ⁇ 3 of the straight line 10: (x + 2y) °, ... etc.
- the following applies to the last group n in the fiber passage direction F: ⁇ n (x + ny) ° ⁇ 90 °.
- the alley width g thus moves asymptotically towards zero, or tg ⁇ n ⁇ .
- the embodiment according to FIG. 6 is similar to that according to FIG. 3 in that one can speak of a rib stitch, but the offset within a respective group 11, 12, 13 ... follows the embodiment or the embodiments according to FIGS. 1 and 2.
- the respective curve line C is drawn in FIG. 4.
- the individual groups 11, 12, 13 ... each contain the same mathematical regularity of the offset or the curve line C.
- the embodiment according to FIG. 7 differs from the embodiment according to FIG. 6 in that, similar to FIG. 5, the individual groups 14, 15, 16,... Do not have the same pattern, but rather the degree of decrease in the offset of the groups 14. 15, 16, ... is increasing in the fiber passage direction F.
- all curve lines C have the same mathematical regularity.
- the increase in the slope of the curve C 2 is greater than that of the curve C1
- the increase in the slope of the curve C 3 is greater than that of the curve C 2 , ...
- FIG. 8 An embodiment is shown in which only the offset of the first tooth tips 2 and thus the aisle widths g determined by them decrease in the fiber passage direction F. These first tooth tips 2 again determine a curve line C which has one of the above-mentioned regularities. The second tooth tips 3, however, define a diagonal line G. Thus, tooth bridges 1 of different lengths are present in this cover set.
- FIG. 8 can also be grouped similarly to the embodiments according to e.g. B. FIGS. 6 and 7.
- the shape and position of the fibers are changed gradually and to an increasing extent during parallelization, the fibers are thus treated more gently and congestion effects when the lid is being run in can be prevented.
