Definitions

  • the invention relates to a scraper fitting for the cover of a carding machine, with a plurality of wire strips lying against one another, each having a row of teeth and a foot.
  • the working parts of the carding machines are the rapidly rotating drum and the lids moving along part of the circumference of the drum. These covers are moved in the direction of rotation of the drum, their speed being many times smaller than the peripheral speed of the drum.
  • the drum is wrapped with a toothed metal wire.
  • the lids are either provided with hooks stuck through a carrier or have a plurality of serrated wire strips, similar to those of the drum.
  • the interaction between the teeth of the drum and the teeth of the coverings dissolves, cleans and parallelises the fiber material and forms it into a fleece, which is then compressed into a card sliver.
  • GB-A-616 185 discloses a scraper fitting for covers of a carding machine, which has a multiplicity of wire strips lying against one another, each of which has a row of teeth and a foot.
  • the wire strips are lined up laterally on an elongated support and biased against one another.
  • the wire strips are held immovably by means of locking members acting on the two outermost of the lined-up wire strips while maintaining the pretension on the carrier.
  • the wire strips are clamped onto the carrier by a wedge which penetrates the carrier lengthways.
  • US-A-4 221 023 shows a scraper fitting with profile-shaped clips, which clamp the wire strips on the one hand on an elongated plastic carrier and, on the other hand, these together with the wire strips on the cover by means of specially shaped webs.
  • two longitudinal grooves are formed in the plastic carrier for receiving an adhesive connecting the wire strips to the plastic carriers.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a scraper fitting for the lid of a carding machine, in which the wire strips are held clamped immovably on a carrier in a simple manner and with a small amount of material.
  • reference number 15 denotes a wire strip of the so-called all-steel card clothing.
  • each lid of a carding machine is provided with a large number of such wire strips 15.
  • the wire strip 15 shown here is a so-called profile with a double foot.
  • the wire strip 15 is provided with a row of teeth 5. This row of teeth 5 extends along a spacer 8.
  • a web 6 runs below the spacer 8 and ends at the foot 7 below. At both ends of the web 6 there is an inclined recess 4 which is intended to receive a leg 9 of the clamp 11 connecting the scraper fitting to the cover 10 (see FIG. 4).
  • a rectangular opening 1 is formed in the web 6 of the wire strip 15.
  • a plurality of wire strips 15 are lined up on a carrier 20, which carrier 20 extends through the respective opening 1.
  • the carrier 20 is a rectangular profile, the opening 1 obviously being designed in accordance with the profile.
  • the carrier 20 can have different cross-sectional shapes, for example it can have an oval cross-sectional shape, a rounded cross-sectional shape, a U-shaped, I-shaped, etc. cross-sectional shape.
  • a slot-shaped opening 16 is formed at the end region of the carrier 20.
  • a locking member 17 in the form of a block is pushed onto the carrier 20. This block is also provided with inclined recesses 4 and an opening 3.
  • wire strips 15, viewed in the longitudinal direction of the rod 20, are prestressed against one another and the block 17 is applied and locked in this mutually prestressed position of the wire strips 15 in such a way that the complete package of wire strips 15 remains under tension.
