Definitions

  • the invention relates to a scraper fitting intended for connection to the flat bars of a card, which has a plurality of teeth-containing wire strips connected to a carrier part.
  • the cards serve to open, comb, and clean fibers.
  • the revolving flat cards have a rotatable card cylinder for this purpose, the jacket of which is provided with a scratch fitting. This interacts with a large number of flat bars which are also moved with respect to it and also provided with a scratch fitting.
  • Known flat bars have a carrier which carries the scraper fitting. For this purpose either wires inserted into a flexible strip or sections arranged on a rigid support, strips of a toothed metal wire, are used.
  • strip-shaped supports with a recess running in the longitudinal direction thereof are used according to the prior art, in which recess the strips of the metal wire are used next to one another.
  • the connection of the metal wire to the bottom of the off Acceptance takes place by means of adhesive, or if the carrier is made of plastic, for example, the metal wires are pressed into it when it is cast.
  • the carrier is then connected to the rod, for example by means of adhesive or by means of clamp-shaped components.
  • the recess obviously does not extend to the longitudinal edge of the strip-shaped carrier, there are empty spaces between adjacent lids in which no carding takes place. If the scratch wires are pressed into the plastic carrier or if there is adhesive between the respective scratch wire and the bottom of the recess, the orientation of the scratch wires relative to the carrier is severely impaired and poor because in both cases when the scratch wires are inserted, they are placed on a flexible surface.
  • the aim of the invention is to eliminate the disadvantages mentioned.
  • the carrier is a rolled iron profile, that the width of the iron profile is equal to the length of the wire strip, and that each wire strip is welded at its ends to the longitudinal edge areas of the iron profile.
  • a plurality of wire strips are connected to respective longitudinal regions by means of a welding bead running at the ends thereof.
  • the section of the wire strip located between the welding points can lie directly on the carrier part.
  • the carrier part can in turn be a section of an iron profile with a bow-shaped cross-sectional shape, which has a base section and two leg sections projecting therefrom, each by means of an arc cut can be formed with the base portion and the arc portions.
  • the support part can be connected to a further, rolled iron profile with a bow-shaped cross-sectional shape, which has a base section and two leg sections protruding therefrom, each of which is connected to the base section by means of an arc section, the support part being connected to the base section, and its longitudinal edges in each case align with the outside of the leg sections.
  • the carrier part and thus the scraper fitting arranged thereon are designed in an arcuate manner such that the same distance prevails between all tooth tips of the carding cylinder and all tooth tips of the flat bars.
  • FIG. 1 shows a carrier part 20 in the form of a rolled, flat iron profile piece.
  • the sawtooth wire 6 is placed on this carrier part 20 such that it lies directly on the carrier part 20.
  • the sawtooth wire 6 is welded to the inner edges of the carrier part 20 by means of a weld 7, 8 at both extreme ends.
  • the sawtooth wire 6 is dimensioned in this way, ie it has a length such that its two end faces 9, 10 are aligned with the ends of the carrier part 20.
  • a large number of sawtooth wires 6 are arranged in a packet-like manner on the carrier part 20 during manufacture. All sawtooth wires 6 are then connected to the ends of the carrier part 20 by means of a welding bead 7, 8 in each case. If necessary, the outside of the welding beads 7, 8 can still be ground, milled, such that the longitudinal sides 13, 14 of the carrier part 20 describe a plane in which the end faces 9, 10 of the carrier part 20 and the outer surfaces of the welding beads 7, 8 lie.
  • the carrier part 20 and the sawtooth wires 6 connected to it, the so-called scratching fitting can be connected in various ways to the actual flat bars of the card. For example, on the Embodiments disclosed later in this description pointed.
  • FIG. 2 A further exemplary embodiment is shown in FIG. 2. This differs from the exemplary embodiment shown in FIG. 1 in that the carrier part 21 extends in an arcuate manner and thus the sawtooth wire 6 placed on the concave side of the carrier 20 also extends in an arcuate manner. Again, the end faces 9, 10 of the sawtooth wire 6 are aligned with the long sides 13, 14 of the carrier part. Here too, the sawtooth wires 6 are connected to the carrier part 21 by means of welding beads 7, 8. The card's flat bars interact with the card cylinder, as mentioned at the beginning.
  • the carrier part 22 is the base section of a bow-shaped iron profile piece, to each base section of which an arc section 2, 3 connects, which merges into a leg section 4, 5.
  • the connection of the bow-shaped carrier formed from the sections just mentioned to the respective flat bar is carried out in such a way that the ends of the leg sections 4, 5 are bent into recesses in the respective flat bar in such a way that the carrier is clamped onto the respective flat bar well known forms not part of the present invention and is therefore not described in detail.
  • the respective sawtooth wire 6 is placed on the carrier part 22 describing the base section in such a way that it abuts directly on the carrier part 22. At both extreme ends, the respective sawtooth wire 6 is connected to the respective arc section 2, 3 by means of a weld 7, 8.
  • a weld 7, 8 For this purpose, it must again be noted that there are sawtooth wires 6 arranged in groups, each of which is connected to the arc sections 2, 3 by a welding bead 7, 8.
  • the welding material of the welding bead 7, 8 is arranged in such a way that it is aligned on the outside with the end faces 9, 10 of the sawtooth wire 6, or all of the sawtooth wires 6, and also with the outside surfaces 11, 12 of the leg sections 4, 5.
  • the embodiment shown in FIG. 4 corresponds to the course of the carrier part 23 and the sawtooth wire 6 according to that of FIG. 2 with the same technical advantages.
  • the bow-shaped support is composed of the support part 23, which is the base section of the bracket, to which arc sections 2 and 3 adjoin, which merge into the leg sections 4 and 5.
  • the welding beads 7, 8, which are arranged next to the end faces 9 and 10 of the sawtooth wire 6, are arranged further indented in comparison with the exemplary embodiment in FIG. 3 such that the sawtooth wire 6 protrudes somewhat over the welding beads 7, 8 on both end faces 9, 10, but, seen in the cross section shown, does not align over the outer faces 11, 12 of the leg sections 4 and 5.
  • the sawtooth wire 6 (or the packs of sawtooth wires) is on a carrier. part 20 welded in the form of a flat iron profile.
  • the welding points or welding beads 7, 8 are again (see FIG. 1) at the end faces 9, 10 of the respective sawtooth wire 6 or the longitudinal sides 13, 14 of the carrier part 20.
  • the carrier part 20 is welded 15, 16 to an iron profile piece welded with a bow-shaped cross-sectional shape.
  • the carrier part 20 lies flat on the base section 24 of the bracket.
  • At the base section 24 there are two curved sections 2, 3 which, as in the exemplary embodiment in FIG. 3, merge into leg sections 4, 5.
  • the arrangement is again chosen such that the outer surfaces 11, 12 of the leg sections 4, 5 . aligned with the end faces 9, 10 of the sawtooth wire 6. An increased formation of the scraper fitting, in particular of the carrier thereof, is thus achieved.
  • Fig. 6 shows an embodiment with an arcuate support 21 in the form of a rolled iron profile.
  • the respective sawtooth wires 6 are welded to the carrier part 21 by means of welding beads 7, 8 in the area of their end faces 9, 10.
  • This arrangement corresponds to that shown in FIG. 2.
  • the carrier part 21 is welded to the base section 25 of an iron profile piece with a bow-shaped cross-sectional shape by means of welds 17, 18.
  • the arc sections 2, 3 connect again, which into the leg sections 4, 5 pass over. It can be seen again that the long sides 13, 14 of the carrier part 21 are aligned with the outer surfaces 11, 12 of the leg sections 4, 5.
