Definitions

  • the present invention relates to an all-steel clothing for clothed elements of openers, cleaners, carders, or carding machines.
  • All-steel clothings are used in various areas in the processing of textile fibers.
  • the present invention relates to a clothing wire for use on clothed elements such as plates, profile rods, or rollers in fiber-processing processes.
  • the clothing wire in the form of a sawtooth all-steel clothing is wound onto the roller in a helical shape with the clothing wires closely adjacent to one another, or in grooves.
  • the clothing wire is cut into wire segments corresponding to the dimensions of the plates or profile rods, and the clothing wires are mounted closely adjacent to one another on the surface of the plates or profile rods.
  • Common forms of sawtooth all-steel clothings are given in International Standard ISO 5234.
  • all-steel clothings are characterized, among other criteria, by their working angle ⁇ , their tooth pitch p, and the tooth depth h 6 , the overall height of the wire h 1 , and the blade width at the tip b 3 .
  • the working angle ⁇ is the angle between the front face and the vertical axis of the wire base; the front face, viewed in the direction of movement, represents the front tooth face. If the working angle is 0°, the front face is thus perpendicular to or vertical with respect to the wire base.
  • An object of the invention is to provide a clothing wire which allows prolonged maintenance intervals for the elements fitted with this clothing wire. Additional objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
  • a clothing wire for clothed elements for use in textile machines wherein the clothing wire is made up of a root and a blade having an overall wire height h 1 of 1.5 mm to 15 mm.
  • the overall height h 1 of the wire is preferably 2 mm to 12 mm, particularly preferably 7.5 mm.
  • the blade is provided with teeth having a tooth depth h 6 of 0.5 mm to 10 mm; the tooth depth h 6 is preferably 1 mm to 6 mm, particularly preferably 4.5 mm.
  • the clothing wire has a tooth pitch p of 1.5 mm to 15 mm; the tooth pitch p is preferably 2 mm to 12 mm, particularly preferably 10 mm (corresponding to 2.5 tips per inch).
  • the teeth are formed in such a way that, viewed in a first working direction, they have a first tip with a first working angle, and viewed in a second working direction, have a second tip with a second working angle, and the first tip is joined to the second tip via a concave tip face.
  • a concave formation is understood to mean a recess between the first tip and the second tip that is oriented in the direction of the root.
  • the recess may be designed, for example, as a semicircular indentation or as an essentially rectangular depression.
  • a clothing wire for clothed elements in the form of rollers advantageously has an overall height h 1 of 5 mm to 15 mm, a tooth depth h 6 of 3 mm to 10 mm, and a tooth pitch of 3 mm to 15 mm.
  • the clothing wire in a first working direction, and also in a second working direction opposite to the first working direction.
  • the clothing wire is helically wound onto a roller, this corresponds to the use of the same clothing wire in one or the other rotational directions of the roller.
  • the clothing wire may be further used in the second working direction simply by rotating the clothed elements on the clothings which are mounted on the elements.
  • the second tip is advantageously designed with a slightly smaller tooth depth compared to the first tip.
  • the lower tooth depth results from a smaller height of the tooth or a lower overall height of the clothing wire at the location of the second tip. That is, the remaining blade height from the tooth base to the blade is unchanged over the entire tooth base.
  • the first working angle and the second working angle are between ⁇ 10° and 30°.
  • the first and the second working angles, adapted to the intended use, may in fact be different. It is conceivable that a tougher clothing is necessary for a first working direction than for a second working direction. The so-called toughness of a clothing increases with an increasing working angle. Teeth having a large working angle engage more forcefully with the fiber material to be processed.
  • the first working angle and the second working angle are equal.
  • the clothing wire thus always has the same toughness, regardless of the working direction or the rotational direction of the roller.
  • the clothing wire has a tooth length of 2.5 mm to 7.5 mm, preferably 3 mm to 5 mm, particularly preferably 3.5 mm, from the first tip to the second tip.
  • the tooth length has a significant effect on whether unintended wear on the second tip results during use of the first tip.
  • the concave shape of the tip face which facilitates the fiber movement, also counteracts wearing down of the second tip during use of the first tip in a first working direction.
  • a tip face having a radius of 1.5 mm to 7 mm has been found to be advantageous.
  • the radius of the tip face is to be appropriately coordinated with the tooth length.
  • the blade width b 3 at the tips is appropriately adapted to the high load on the clothing wire.
  • the clothing wire has a blade width b 3 of 0.05 mm to 1.5 mm at the first and second tips; the blade width b 3 at the tips is preferably 0.7 mm to 0.9 mm, particularly preferably 0.8 mm.
  • a clothing wire for use in a clothed element in the form of a roller has a blade width b 3 of 0.1 mm to 1.5 mm at the first and second tips.
  • the tooth base radius is likewise to be selected according to the use of the clothing wire; a relatively large tooth base radius contributes to the avoidance of clogging of the tooth base with fibers, dirt, or fabric residues.
  • the tooth base radius for the first tip is 0.3 mm to 4.0 mm, preferably 2.0 mm to 3.0 mm.
  • the tooth base radius for the second tip is advantageously equal to the tooth base radius for the first tip.
  • the clothing wire may be designed with a normal, interlocking, or concatenated root to allow winding even onto a smooth roller or into grooves.
  • the clothing wire is particularly suited for clothed elements or rollers of textile machines, for example openers and cleaners or cotton cards or roller carding machines.
  • the clothing wire When the clothing wire is used on a roller, it is helically wound.
  • this roller has a symmetrical design, after the first tips of the clothing wire have worn down the roller may be rotated in order to make use of the second tips of the clothing wire.
  • the operating time that elapses before it is necessary to replace the clothing of a corresponding roller is doubled.
  • the same principle applies for use of the clothing wire on plates or profile rods.
  • FIG. 1 shows a schematic illustration of one embodiment of a clothing wire
  • FIG. 2 shows a schematic illustration of a cross section of a clothing wire.
  • FIG. 1 shows a schematic illustration of one embodiment of a clothing wire 1 having a root 2 and a blade 3 .
  • the root 2 and the blade 3 extend over the overall height h 1 of 7.5 mm.
  • the blade 3 is provided with teeth 4 which are situated in succession along the clothing wire 1 at specific intervals, the so-called tooth pitch p.
  • the teeth 4 have identical shapes, and are regularly arranged along the clothing wire 1 with a tooth pitch p of 10 mm.
  • the teeth 4 have a tooth depth h 6 of 4.5 mm, and on the side facing away from the root 2 end in a first tip 5 and a second tip 6 .
  • the tooth depth h 6 extends from the first tooth tip 5 to the tooth base 8 .
  • the first tip 5 is joined to the second tip 6 via a concave tip face 7 .
  • the concave tip face 7 is designed with a circular recess having a radius D of 3 mm.
  • the tooth 4 has a lower tooth depth than the tooth depth h 6 at the location of the first tooth tip 5 .
  • This difference in height between the second tooth tip 6 and the first tooth tip 5 results in a height difference E of 0.02 to 0.5 mm.
  • the height difference E results from a lower overall height of the clothing wire 1 at the location of the second tip 6 compared to the overall height h 6 at the first tip 6 of the tooth 4 .
  • the tooth base 8 is always the same distance from the root 2 .
  • the tooth 4 has a tooth length C of 3.5 mm, the tooth length C corresponding to the distance from the first tip 5 to the second tip 6 of the tooth 4 .
  • the so-called front face 9 which, viewed in the direction of movement, leads from the tooth tip 5 to the tooth base 8 , represents the front tooth face.
  • the working angle ⁇ is the angle between the front face 9 and the vertical axis of the wire base. Viewed in a first working direction X, the working angle ⁇ is illustrated to be 10°, and in a second working direction Y the working angle ⁇ is likewise illustrated to be 10°.
  • the front face 9 viewed in the first working direction X, with a tooth base radius G of 2 mm, is joined to the tooth base 8 . Viewed in the second working direction Y, a tooth base radius of likewise 2 mm is provided.
  • the exemplary embodiment shown thus represents a tooth 4 having a symmetrical shape, disregarding the height difference E between the second tip 6 and the first tip 5 .
  • FIG. 2 shows a schematic illustration of a cross section of a clothing wire 1 in various embodiments.
  • a clothing wire 1 having a root 2 and a blade 3 is illustrated in all embodiments.
  • the blade 3 starting from the root 2 , tapers to a blade width b 3 of 0.8 mm at the first tip 5 .
  • a clothing wire 1 in an embodiment having a normal flat root 2 is illustrated in the left diagram of FIG. 2 .
  • This embodiment of the clothing wire 1 corresponds to the standard design used in machines for fiber processing processes.
  • the middle diagram shows an embodiment of a clothing wire 1 having a concatenated root 2 , which is used in openers, for example.
  • the right diagram shows an embodiment of the clothing wire 1 having an interlocking root 2 , which is used in cleaners, for example.
