Definitions

  • the present invention relates to an all-steel garnish for use on drums in carding machines. Steel wire cloths are used in various areas of textile fiber processing.
  • the present invention relates to a garniture wire for use on rolls in fiber processing processes, in particular to drums of carding machines.
  • the clothing wire in the form of a sawtooth all-steel garniture is helical and tightly abutted or wound in grooves on the roller. Usual forms of the sawtooth all-steel fittings are given in the international standard ISO 5234 (2004).
  • All-steel sets are characterized according to the norm inter alia by their back angle ⁇ , their pitch p and the tooth depth h 6 , the total height of the wire h 1 and the blade width at the top b 3 .
  • the back angle ⁇ is the angle between the back surface and the wire base, wherein the back surface is the rear tooth surface viewed in the direction of movement. Is the back angle 90 ° so that the back surface is vertical, respectively vertical, to the wire base.
  • a clothing wire for use on drums in cards wherein the clothing wire of a foot and a sheet with a Total height of the wire h 1 is 1.5 mm to 5.0 mm.
  • the total height of the wire h 1 is 1.8 mm to 3.0 mm, particularly preferably 2.0 mm.
  • the blade is provided with teeth with a tooth depth h 6 of 0.35 mm to 1.0 mm, preferably the tooth depth h 6 is 0.4 mm to 0.6 mm, particularly preferably 0.45 mm.
  • the clothing wire has a tooth pitch p of 1.5 mm to 3.0 mm, preferably the tooth pitch p is 1.6 mm to 2.0 mm, particularly preferably 1.67 mm (corresponding to 15 tips per inch).
  • the teeth have a tip surface, a back surface with a back angle, and a tooth surface. The back angle is 40 ° to 20 °, preferably 20 ° to 30 °, more preferably 23 °.
  • Each tooth has a first tip and a second tip, and the tip surface has at least one protrusion.
  • the fiber transfer Due to this geometry of the teeth with two tips, a tip surface and a back surface sloping down to a tooth base with a small back angle, the fiber transfer, the transfer of the fibers to a subsequent roller, is favored.
  • the two tips per tooth also have an advantageous effect on the fiber transfer and result in a considerable reduction in fiber damage.
  • the top surface with the intended elevation causes the fibers to be held on the surface of the clothing. Nevertheless, a pad forms in the Garniturfuss favored by the back surface, which also causes a reduction in fiber damage.
  • the first tip is connected to the tooth base via a first concave, respectively semicircular, surface segment.
  • the concave first surface segment between the tooth base and the first tip advantageously has a tooth root radius of 0.1 mm to 0.7 mm, preferably the tooth root radius is 0.1 mm to 0.3 mm.
  • the first tip is connected to the second tip via a second concave, respectively semicircular, surface segment, which advantageously has a radius of 0.05 mm to 0.5 mm, preferably, the radius is 0.08 mm to 0.3 mm.
  • the tip surface as a whole is not made to be a flat surface but has a tip surface radius of 0.2 mm to 0.5 mm.
  • This tip surface which is made with the tip surface radius, begins a few hundredths of a millimeter after the actual second tip and merges into the elevation. This has the advantage that forms a pronounced second peak.
  • the entire top surface is thus composed of several tip surface sections.
  • a first tip surface portion between the second tip and the tip surface radius-provided tip surface is formed as a flat surface having a length of 0.03 mm to 0.15 mm and a tip surface angle of 6 ° to 10 °.
  • the tip surface angle is the angle between the tip surface and the wire base.
  • a second tip surface portion following the first tip surface portion is made concave and provided with the tip surface radius.
  • a third tip surface portion following the second tip surface portion is formed by the protrusion.
  • the survey advantageously has a radius of 0.1 mm to 0.3 mm.
  • elevation is meant that the tip surface approaching, starting at the second tip, with increasing distance from the second tip of the wire base, but away at the location of formed by the elevation third tip surface portion of the wire base again.
  • the elevation relative to the second peak has a height difference of 0.02 mm to 0.5 mm. The second peak surmounted the survey to this height difference, which also contributes to an improvement in the possibilities of regrinding the Garniturdrahtes.
  • the third elevation surface portion formed as an elevation is followed by the back surface.
  • the third tip surface portion is followed by a further tip surface portion, which is formed as a further elevation.
  • the height difference of this further survey to the second peak is greater than or equal to the height difference of the first survey to the second peak.
  • the clothing wire has a blade width at the second tip of 0.05 mm to 0.3 mm, and a foot width of 0.3 mm to 1.0 mm.
  • the clothing wire can be made with a normal, locked or interchangeable foot to allow it to be mounted on a smooth roller or in grooves.
  • the clothing wire is particularly suitable for garnished rolls of cards, such as the drums. When using the clothing wire on a drum this is wound up spirally.
  • FIG. 1 shows a schematic representation of a view and FIG. 2 a cross section of an embodiment of a clothing wire 1 with a foot 2 and a sheet 3.
  • the foot 2 and the sheet 3 extend over the total height h 1 of 2.0 mm.
  • the sheet 3 is provided with teeth 4, which are arranged behind one another along the clothing wire 1 at a certain distance, the so-called tooth pitch p.
  • the teeth 4 are regular and identical in shape along the Garniturdrahtes 1 with a pitch p of 15 peaks per inch arranged.
  • the leaf 3 constructed on the foot 2 tapers from the foot 2 to a leaf width b 3 of 0.06 mm at the second tip 6.
  • the foot 2 has a foot width b 1 of 0.5 mm at the side opposite the second tip.
  • the teeth 4 have a tooth depth h 6 of 0.45 mm and end on the side facing away from the foot 2 in a second tip 6.
  • the tooth depth h 6 extends from the second tooth tip 6 to the tooth base 10th
  • Each tooth 4 has a first tip 5 and a second tip 6.
  • the first tip 5 forms the front side of the tooth 4, the so-called breast surface.
  • the tip surface 7 includes a projection 9 with a subsequent back surface 8.
  • the back surface 8 extends with a back angle ⁇ of 23 ° inclined to the tooth base 10th
  • FIG. 3 shows an enlarged schematic representation of a single tooth 4 of the clothing wire 1 after FIG. 1 From the tooth root 10 to the second tip 6, the breast surface of the tooth 4 is shown, wherein this is formed to the first tip 5.
  • the tooth base 10 is connected to the first tip 5 via a first concave surface segment which has a tooth root radius G of 0.15 mm.
  • the first tip 5 is connected to the second tip 6 via a second concave surface element which has a radius H of 0.1 mm.
  • the second tip 6 is in turn connected to the following tooth base by a tip surface 7 and a subsequent back surface 8.
  • the tip surface 7 is composed of a plurality of tip surface portions 11, 12, 9 together.
  • the first tip surface portion 11 is formed from the second tip by a flat surface.
  • the second tip surface portion 12 following the first tip surface portion 11 is formed as a concave surface having a radius D of 0.3 mm.
  • the third tip surface portion is formed by the elevation 9.
  • the elevation 9 has a radius E of 0.15 mm and at its highest point has a height difference C of 0.08 mm to the second peak 6.
