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 interplay of the teeth of the drum and the teeth of the lid dissolves, cleans and parallelises the fiber material and forms it into a fleece, which is then compressed into a card sliver.
  • DE-OS 2 145 459 discloses scraper fittings, the connection between the toothed wire strip and its carrier, which is connected to the flat bar, being formed by means of welds or adhesives. This welding or gluing means a longer expenditure of time and associated, considerable manufacturing costs.
  • the invention seeks to remedy this. Which he Finding, as it is 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 non-displaceably on a carrier.
  • reference number 15 denotes a wire strip of the so-called all-steel card clothing.
  • each cover 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 is an inclined recess mung 4 available, which is intended for receiving a leg 9 of the bracket 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.
  • the section of the block 17 which closes the opening 3 at the bottom is divided into two parallel longitudinal bars 18 and 21 which run in the longitudinal direction of the block 17.
  • the block 17 is pushed onto the carrier 20 as the last link during assembly.
  • the longitudinal bar 18 acting as a locking part (see FIG. 3) is then plastically deformed upward in an arcuate manner such that the deformed longitudinal bar 18 engages in the slot-shaped opening 16 at the end of the carrier 20. 1 shows this position of the block 17 at the end of the carrier 20 with the wire strips 15 lined up thereon.
  • wire strips 15, viewed in the longitudinal direction of the rod 20, are prestressed against one another and the block 17 is applied to the wire strips 15 in this mutually prestressed position and is locked such that the complete package of wire strips 15 remains under tension.
  • the carrier 20 has the slit-shaped opening 16 and the block 17 acting as a locking member at both ends.
  • one end of the elongate carrier is provided in one piece with an end block, for example has a T-shaped end, in which case only the opposite end of the carrier 20 is provided with a block 17.
  • FIG. 4 shows a diagram and in section of the wire strips 15 lined up on the carrier 20, that is to say the scraper fitting, which is connected to the cover 10 of the carding machine.
  • the connection is formed by a clamp 11, which engages with a leg 9 in the oblique slots 4, both the wire strip 15 and the block 17. It can be seen that neither a weld seam nor any adhesives according to the prior art are necessary in order to connect this scraper fitting to the cover 10.
  • FIGS. 5 and 6 A further exemplary embodiment is shown in FIGS. 5 and 6.
  • the wire strips 15 of this embodiment are not double-footed wire strips, but the embodiment which only has the row of teeth 5 and the foot 7.
  • the row of teeth 5 does not extend to the two ends of the wire strip in such a way that a toothless foot section 19 remains at both ends.
  • the carrier 24 is here a profile piece, which has a web 12, from the longitudinal edges of which a longitudinal leg 13, 14 extending perpendicularly to each projects downwards. On the side facing away from the longitudinal legs 13, 14, the web 12 has clamping and guide strips 22, 25 pointing from the longitudinal edge towards its center.
  • the individual wire strips 15 with the toothless foot sections 19 are pushed into the space 12 and strips 22 and 25 and are prestressed against one another again in the longitudinal direction of the carrier 24.
  • the end sections 23 of the strips 22, 25 are clamped against the toothless foot sections 19 of the wire strips 15 located there, so that the pretension of the lined-up wire strips 15 is maintained again.
