Definitions

  • the invention relates to a device for processing textile fibers according to the preamble of patent claim 1, a suitable for producing such a device carding and usable for producing these carding sawtooth wire sections.
  • FIG. 3 shows a schematic representation of the basic structure of a carding machine or carding machine.
  • the carding machine has a supply channel, generally designated 12, for supplying the fiber material consisting of disordered fibers to a pre-release section 20. With this Voretzlösesetation 20, the fiber material is presented to the drum 30 of the card.
  • This tambour is a roller, which is provided on its outer surface with a tick and / or sawtooth all-steel set.
  • the spool When operating the card, the spool is rotated about its roller axis. In this case, the fibers presented by the pre-resolution section are detected by the clothing and aligned in the direction of rotation of the roller.
  • flat bars 32 are arranged distributed in the circumferential direction over the lateral surface of the spool. These flat bars have a work surface facing an working position of the lateral surface of the main cylinder, which can also be formed in the form of a tick and / or sawtooth all-steel garnish.
  • the flat bars can be either fixed or moved in a direction opposite to the direction of rotation of the spool direction.
  • the nonwoven fabric is removed with a doffer roller 14 and fed to further processing.
  • the pre-resolution section on the one hand serves for a controlled feeding of the disordered fiber material to the spool and, on the other hand, for a uniform distribution of the fiber material over the entire axial length of the spool.
  • Fig. 4 shows a detailed illustration of this pre-resolving section 20.
  • a total of 3 lickerin rollers 22, 24 and 26 are provided which are rotatable about the roller axes 22a, 24a and 26a in the directions indicated by the arrows A.
  • Each of the licker-in rollers 22, 24 and 26 has a circular cylinder jacket-shaped processing surface, which can be equipped with a tick and / or sawtooth all-steel set.
  • Fig. 5 shows a section along a direction perpendicular to the roll axis 26a cutting plane
  • Fig. 5b is a plan view of the Festkardierelement 27. From Fig. 5a shows that the Festkardierelement 27 essentially of a support member 27a and fixed on this support member 27a sawtooth wire sections 27b exists.
  • these sawtooth wire sections 27b extend approximately tangentially to the lateral surface of the lickerin roller 26, which is likewise provided with a sawtooth all-steel fitting.
  • the fixed carding element has a multiplicity of sawtooth wire sections arranged side by side and fixed on the carrier element 27a.
  • the Festkardieriana have a width of about 32 to 52 mm and are made of cast iron, steel, aluminum, magnesium or synthetic material, wherein between the tips of the shegezierdrahtstsammlung 27 b and those of the set of lickerin a minimum distance in the order of 0 , 1 to 1.0 mm is complied with.
  • An inventive Kardierelement has at least one working surface and is characterized essentially in that this processing surface has a concave, approximated to a circular cylinder surface shape, said processing surface two or more each in a plane perpendicular to the cylinder axis cutting plane an obtuse angle of preferably 160 ° 170 °, in particular about 165 ° with each other enclosing polygon sections may have.
  • the carding element according to the invention comprises a rigid scraping segment, which forms the working surface and is fixed to a carrier element of the carding element.
  • the scraping segments of the carding element according to the invention have at least one sawtooth wire section with two an obtuse angle of preferably about 160 ° to 170 °, more preferably about 165 °, including each other Segments on, wherein the support member corresponding, an obtuse angle with each other enclosing bearing surfaces for the scraper segment comprises. It can be provided between these bearing surfaces a recess in the support member to attach it with a crease sawtooth wire sections can attached.
  • the carrier element may have a V, W or multi-W-shaped basic shape.
  • Kardieriana is a suitable for the production of sawtooth wire section is essentially characterized in that it is in one piece and two obtuse angle enclosing segments, wherein between these segments a kink exhibiting connection segment be provided without tooth design can.
  • FIG. 1 shows a device 100 according to the invention as part of a pre-resolution section of a card.
  • 1a shows a sectional view in a sectional plane running perpendicular to the axis of a lickerin roller
  • FIG. 1b shows a plan view of the carding element illustrated in FIG. 1a.
  • the apparatus comprises a lickerin roller 110, of which only a section of the circular cylinder jacket-shaped processing surface is shown and a carding element.
  • the carding element comprises a carrier element 120 and a plurality of juxtaposed sawtooth wire section 130. The arrangement of the sawtooth wire sections can be seen particularly clearly in the plan view of FIG. 1b.
  • the sawtooth wire sections 130 have two segments 132 and 134 at an obtuse angle, which are connected to one another via a connection segment 136.
  • the connecting segment 136 has a bend corresponding to the obtuse angle and is designed without saw teeth, so as to facilitate the formation of kinking.
  • the support member 120 comprises two bearing surfaces 122 and 124 for the segments 132 and 134. These bearing surfaces are each made flat and include a shape corresponding to the sawtooth wire sections corresponding to an obtuse angle. Between the bearing surfaces 122 and 124, a recess 126 for receiving the bent connecting segment 136 is provided. Overall, the carrier element 120 has a W-shaped basic shape. The recess 126 is delimited on the side facing away from the sawtooth wire section 130 by a web 137. On the side facing away from the sawtooth wire sections 130 of the web 137, a further downwardly opening recess is provided with a T-shaped cross section, which serves to receive a complementary thereto formed fastener
  • two Faserverstreichzonen 140 and 150 are formed between the set of lickerin 110 and the Festkardierelement.
  • FIG. 2 shows a detailed view of the sawtooth wire sections 130 according to FIG. 1.
  • FIG. 2a shows a side view of these sawtooth wire sections
  • FIG. 2b shows a sectional view along the sectional plane AA in FIG. 2a.
  • the extension of the segment 132 with the segment 134 includes an angle ⁇ of about 15 °. This means that the segments 132 and 134 enclose an angle ⁇ of about 165 ° with each other.
  • the angle ⁇ of 15 ° is used for licker-diameter of about 180 mm. For larger pre-overs diameters, a much smaller angle can be used. As can be seen particularly clearly in FIG.
  • each of the segments 132 and 134 has a number of saw teeth 138 arranged one behind the other, while the connecting segment 136 is designed without saw teeth.
  • the sawtooth wire section 130 has a foot section 130a and a leaf section 130b, wherein the saw teeth are formed within the blade portion 130b.
  • the foot portion 130a has a larger width than the blade portion 130b. Therefore, when a plurality of sawtooth wires of the kind shown in Fig. 2 are sealed, a fitting groove is formed between the blade portions 130b.
