Definitions

  • the invention relates to a combing device according to the preamble of patent claim 1.
  • the combing machine serves to refine yarns made from textile fibers. It is usually arranged between the card and the track during yarn production.
  • the main tasks of the comber consist in the excretion of short fibers from the card sliver produced by the card, ie in the improvement of the stack of raw fiber material, as well as in the improvement of the parallelization of the individual fibers supplied in the form of the card sliver of the carding nonwoven fabric.
  • a further cleaning of the fiber fleece is achieved in the combing machine by excreting nits and shell parts.
  • the top comb conventional combing machines is usually formed of a support element in the form of a metal strip and soldered comb teeth in the form of flat needles.
  • a strong contamination of the fixed comb is to be observed, which makes frequent cleaning necessary .
  • To eliminate this deficiency will be in the DE 195 31 605 a development of conventional fixed combs proposed in which the comb teeth of the top comb as well as the comb teeth of the circular comb in the form of sawtooth wire sections, each with at least one saw tooth, which has substantially parallel to the combing tooth flanks and a perpendicular thereto extending tooth face, are formed.
  • the sawtooth wire sections used for the production of the fixed comb, as well as the sawtooth wire sections used to make the circular comb may each consist of a foot and an adjoining sheet having at least one sawtooth, the dimensions of the foot being greater in a direction substantially perpendicular to the combing direction are as the dimensions of the sheet in this direction, so as to provide for the passage of the fibers through the respective combing elements during the combing process enabling the combs.
  • a wire-shaped starting material is first subjected to a cold rolling process, so as to produce a wire profile forming the root area and the blade area of the sawtooth wire sections.
  • the saw teeth are removed by a punching process from the profile wire.
  • sawtooth wire sections are cut with a required for the production of a Fixkamms or a circular comb length.
  • the sawtooth wire sections are then combined into bundles and mounted on a suitable support member.
  • the saw teeth a Curing process such as a laser or flame hardening process.
  • the object of the invention is to provide a combing device for combing machines that is particularly easy to produce, with which a high-quality combing belt or a high-quality comber belt can be produced at a high machine running time and operating speed, as well as a method for producing such combing devices provide.
  • the fastening region designed for fastening the combing element to the combing machine can also be embodied in one piece with the comb teeth.
  • combing devices according to the invention when using combing devices according to the invention in the form of circular combs for a combing machine, but also when using combing devices according to the invention in the form of Fixkarmmen for a comber, it has proven to be particularly useful for obtaining a particularly good combing when the combing at least two, preferably three or more in Combing one behind the other arranged comb teeth has.
  • combing devices according to the invention in the form of fixed combs the tips of the comb teeth arranged next to one another in the direction perpendicular to the combing direction are expediently arranged approximately on a straight line running perpendicular to the combing direction.
  • the tips of the combing in succession arranged comb teeth are preferably arranged when using combing devices according to the invention in the form of circular ridges approximately on a circular arc, the center of which falls on the space-fixed axis circumscribed by the circular ridge.
  • combing elements of combing devices according to the invention can be at least partially made of high-alloy steel, in particular stainless chromium-nickel steel, whose cold-forming properties would no longer be sufficient for producing profiled wires.
  • a combing element suitable for the production thereof is essentially characterized in that it has at least two, preferably three or more (possibly 20, 30 or more) arranged side by side in the direction perpendicular to the combing direction and integrally executed comb teeth.
  • An invention according to the invention obtained using combing combs fixed comb is essentially characterized in that it two, three or more has integrally executed comb teeth whose tooth tips are arranged on a straight line extending approximately perpendicular to the Kämmraum.
  • a circular comb produced using combing elements according to the invention comprises two, three or more comb teeth arranged side by side in a direction perpendicular to the combing direction and integrally executed, as well as two, three or more comb teeth arranged one behind the other in the combing direction and integrally formed.
  • Two, three or more combing elements according to the invention can be arranged side by side in a direction perpendicular to the combing direction both for the production of inventive combs and for producing circular combs according to the invention, wherein two, three or more combing elements according to the invention in the combing direction behind each other in particular for the production of circular combs according to the invention can be arranged.
  • a method for producing a combing element according to the invention for a combing device according to the invention is characterized essentially in that starting from an example approximately cuboid raw material block, in particular made of high-alloy steel, such as chromium-nickel steel, in a first processing step, the individual comb teeth in the perpendicular to Then, in a second processing step, the shape of the comb teeth is removed from the raw material block in a view perpendicular to the combing direction, wherein a connection region connecting the comb teeth in the direction perpendicular to the combing direction is used. the fastening area of the raw material block serving to fasten the combing element to the combing machine is maintained.
  • a further acceleration of production methods according to the invention is possible if the raw material block in the second processing step is machined from two directions which are opposite one another and in each case perpendicular to the direction of combing.
  • the sole figure of the drawing illustrates schematically a method for producing inventive combing elements, which are suitable for the production of inventive fixed combs.
  • a block of raw material for example, stainless high-alloy steel such as chromium-nickel steel is used as the starting material for the manufacturing process.
  • the width b of this raw material block can be up to 300 mm
  • the height h of the raw material can be 5 to 15 cm, in particular about 10 cm.
  • the depth t of the raw material block may be 1 to 10 mm, in particular 3 to 5 mm.
  • a first processing step by spark erosion using a multi-erosion head 20 the comb teeth in a direction perpendicular to the direction of combing direction P separating slits 12 separated from the raw material block 10.
  • three slots 12 are simultaneously produced with the aid of the multi-erosion head 20.
  • four or more slots 12 or 2 or fewer slots 12 may be made simultaneously.
  • profiles 50 are simultaneously removed from the raw material block 10 in a direction perpendicular to the combing direction by means of erosion heads 30 and 40 from two opposite and respectively perpendicular directions to the combing direction. These profiles may have a connecting the comb teeth with each other fastening region 54 below the slots 12 and sawtooth-shaped comb teeth 52.
  • comb teeth 52 of any shape, in particular any breast shape, and optionally profiled teeth or tooth flanks can be produced.
  • the flanks of the tooth-shaped prongs 52 may, for example, converge in sections in the direction of the tooth tips symmetrically with respect to a plane perpendicular to the direction P.
  • the invention is not limited to the embodiment explained with reference to the drawing. Rather, it is also connected to the production of Rundkammgarnitur intended by means of inventive method. In this case, multi-erosion heads can also be used in the second processing step to produce the tooth profiles. Next is intended to the production of comb teeth with any tine shapes.
