Definitions

  • the invention relates to a toothed set for a comb of a combing machine with a plurality of adjacent teeth, which form at least one transverse to the direction of the teeth oriented teeth row.
  • the invention has for its object to provide a tooth set for a comb that allows increased combing and combing quality.
  • the object is achieved in that the row of teeth - viewed transversely to the direction of work - has more than 35 teeth per centimeter.
  • a toothed set according to the invention provides a better combing result. It is particularly advantageous if the row of teeth has more than 40 teeth per centimeter, and in particular about 60 to 80 teeth per centimeter. Such a set of teeth is particularly well suited for combing fine fibers with a low micron value.
  • the tooth space extending in the working direction between two adjacent teeth has a depth which is at least 60 times the width of the interdental space transverse to the working direction. It has surprisingly been found that such a ratio between width and depth of the interdental space enables a particularly good combing result at high combing speeds. It is particularly advantageous if the depth of the interdental space is 70 to 250 times, in particular 100 to 200 times, the width.
  • the good combing result is caused by the fact that sufficient space for the fiber mass is created by a particularly large depth of the interdental space. Large fiber masses per unit of time can be processed particularly well when the toothed structure has interdental spaces with a depth that is at least 100 times the width of the interdental space.
  • - viewed transversely to the working direction - the width of the tooth and the width of the interdental space has a ratio of about one to one. Such a ratio improves the combing quality.
  • the tooth space extending in the working direction between two adjacent teeth has a length in the working direction, which is at least 5 times, in particular at least 15 times, the width of the interdental space transverse to the working direction.
  • a relatively large length of the interdental space is achieved by a correspondingly large length of the teeth.
  • a large length of the teeth in the working direction causes a high stability of the teeth relative to the working forces during the combing process. This high stability due to a large length of the interdental space is particularly important in the tooth sets according to the invention because of the high number of teeth of the row of teeth transversely to the working direction.
  • the teeth of the row of teeth are integrally formed.
  • the interdental spaces are formed on a semifinished product of the row of teeth from the solid.
  • Such a production of a toothed set is from the DE 10 2006 030 763 A1 known.
  • a production from the solid is particularly advantageous in the row of teeth according to the invention, since due to the individual dimensions of the teeth production by punching from a wire is not practical. Due to the one-piece design of the row of teeth, the high number of teeth per centimeter can be produced extremely efficiently.
  • the tooth spaces extending in the working direction between two adjacent teeth are formed by a laser.
  • a laser makes it very easy to make a row of teeth with more than 35 teeth per centimeter.
  • a laser allows a very precise burnout of the interdental spaces of a solid material.
  • the method also has a very good repeatability.
  • a method for producing a tooth set should also be provided under protection.
  • the tooth spaces extending in the working direction between two adjacent teeth are formed by a laser.
  • the production of the toothed set is very much simplified.
  • different sets of teeth with different numbers of teeth per centimeter on a laser machine can be produced without major conversion.
  • the toothed set consists of a wear-resistant steel.
  • the wear-resistant steel may be a hardened steel or a per se very hard and wear-resistant steel, for example a chromium-nickel steel. If the steel is hardened to achieve wear resistance, it is advantageous to harden the semifinished product prior to forming the interdental spaces.
  • the manufacturing method according to the invention, in which the interdental spaces are formed by a laser is particularly advantageous.
  • the toothed set may be advantageous to weld the toothed set by a laser with a base body.
  • the toothed set is preferably fastened with a laser welding to a base body for a comb of a combing machine.
  • the toothed set has a positioning surface, with which it bears against a positioning surface of the base body.
  • the positioning surface may have the shape of a projection or a groove. This makes it possible to achieve a defined positioning of the toothed set on the base body.
  • the tooth set according to the invention can be used particularly advantageously for a top comb of a combing machine. In one embodiment, it may also be advantageous to use the tooth set according to the invention for a circular comb.
  • FIG. 1 a tooth set 1 according to the invention for a fixed comb of a comb-machine is shown.
  • the operation of a Fixkammes in a combing machine is known per se and is for example in the DE 10 2006 030 763 A1 described.
  • the toothed set 1 contains a plurality of juxtaposed teeth 2, which form a row of teeth 3.
  • the working direction of the toothed set 1 is in FIG. 1 marked with the arrow A.
  • the row of teeth 3 is oriented perpendicular to the working direction. Between two adjacent teeth 2, a tooth space 4 is present, which extends in the working direction.
  • the tooth 2 Seen transverse to the working direction A, the tooth 2 has a width F and the interdental space 4 has a width B.
  • the widths F and B are respectively measured parallel to the extension of the row of teeth 3.
  • the width B and the width F are constant from the tip of the tooth to the root of the tooth. This is only an advantageous embodiment. It can also be provided that the width B or F varies. At a non-constant width of the tooth 2 and the Interdental space 4 in the context of the present invention in each case the average width prevail.
  • the interdental space 4 has a depth C from the tooth tip to the root of the tooth.
  • the depth C of the interdental space 4 corresponds to the height of the tooth 2.
  • the length of the interdental space 4 seen in the direction A is designated by the dimension D.
  • the length D of the interdental space 4 is measured in the region of the tooth root, since the length D at the tooth tip approaches zero.
  • the toothed set 1 viewed along the row of teeth 3, has approximately 60 to 80 teeth per centimeter.
  • the depth C of the interdental space 4 is approximately 70 to 250 times the width B of the interdental space 4.
  • a tooth set with these dimensions provides particularly good combing results in a very high speed combing machine.
  • the length D of the interdental space 4 is approximately 15 to 50 times the width B of the interdental space 4. Since the following is still the formation of the interdental space 4 in the manufacture of the toothed set 1, the length D is also based on the interdental space 4, although in fact for the stability of the tooth 2, of course, its length in the region of the tooth root is relevant. However, the length D of the interdental space 4 is identical to the length of the tooth 2.
  • width F of the tooth 2 and the width B of the interdental space 4 have a ratio of approximately one to one. This results in a good stability of the teeth at the same time sufficient space for receiving fiber material in the interdental space. 4
  • FIG. 2 a method for producing a toothed set 1 for a fixed comb is shown schematically.
  • the teeth which form the row of teeth 3 on the finished tooth set 1, are formed in one piece from a semifinished product 5.
  • a laser 6 is used.
  • the laser beam emerging from the laser 6 is directed onto the semifinished product 5 and forms the interdental spaces 4 extending in the working direction A by burning away the material of the semifinished product 5 there becomes.
  • the formation of the interdental spaces 4 by the laser 6 is particularly advantageous because even tooth spaces 4 can be formed with a very small width B, a very large depth C and a large length D precise and fast.
  • the transverse to the direction A seen outer contour of the teeth 2 is already finished before forming the interdental spaces 4.
  • FIG. 3 a tooth set 1 is shown, which has been prepared as described above.
  • the toothed set 1 has a positioning surface 7, with which it bears against a positioning surface 8 of a base body 9.
  • the main body 9 may be, for example, the main body of a fixed comb.
  • the base body 9 may consist of a different material than the toothed set 1.
  • This embodiment has the advantage that the amount of very high-quality and wear-resistant material of the toothed set 1 can be reduced.
  • the main body 9 is significantly less stressed and can be made of a simpler material.
  • the toothed set 1 is fixed to the base body 9 by laser welding.
  • the laser welding is indicated by the arrow E.
  • the connection of the toothed set 1 by means of a laser welding E has the advantage that the heat input into the toothed set 1 is very small, so that the material properties of the toothed set 1 are practically not impaired by the welding process.
  • the positioning surfaces 7 and 8 may be formed as tongue and groove, as in FIG. 4 is recognizable.
  • a positive connection between tooth set 1 and basic body 9 improves the positioning. Again, a permanent welding is ensured by a laser welding E.
  • the toothed set 1 is positively secured to the base body 9.
  • the positioning surfaces 7 and 8 engage in a form-fitting manner.
  • glands can be provided for backup. In a worn tooth set this can be easily replaced and a new set of teeth 1 are attached to the base body 9.
