Definitions

  • the present invention relates to an all-steel clothing for rolls of openers, cleaners, carding or carding.
  • the present invention relates to a combination of two wire harnesses for use on garnished rolls in fiber processing processes.
  • the clothing wires are helical in the form of sawtooth all-steel fittings and are wound tightly against each other on the rollers. Usual forms of sawtooth all-steel fittings are given in international standard ISO5234.
  • Metallic wires according to the standard characterized by their working angle ⁇ , ⁇ her back angle at existing peak area I ⁇ its top face angle, its tooth pitch p and the tooth depth h 6, the overall height of the wire h 1, and the foot width B1.
  • the working angle ⁇ is the angle between the breast surface and the vertical axis to the wire base, wherein the breast surface has a slope with the back surface at a positive breast angle and a slope against the back surface of the tooth at a negative breast angle.
  • the tip surface angle ⁇ is the angle between the tip surface of the tooth and the wire base, the tip surface having a slope to the dorsal surface at a positive tip surface angle and a slope against the dorsal surface of the tooth at a negative tip surface angle.
  • EP 1 576 215 discloses an all-steel set, which should have good adoption properties by the selected tooth geometry and prevent clogging of the set.
  • the teeth have a tip surface, which makes them dull against impurities, which prevents the impingement of foreign parts. Due to a positive working angle, the clothing still has an aggressive nature. The disadvantage is that the fibers are drawn into the clothing due to the positive working angle.
  • the all-steel clothing consists of a first clothing wire having teeth with a negative working angle and a tip surface angle of -15 ° to + 15 ° and a second clothing wire having teeth with a positive working angle.
  • the first clothing wire and the second clothing wire are wound in an alternating sequence side by side on the roller and result in their combination the all-steel clothing.
  • the teeth of the first clothing wire have the function of holding the fibers on the surface of the all-steel clothing and of preventing the fibers from penetrating deep into the all-steel clothing. This is essentially determined by the negative working angle, thereby supporting the intended peak area.
  • the main function of the teeth of the second clothing wire is to take along the fibers, which is essentially determined by the positive working angle.
  • the second clothing wire projects beyond the tips of the teeth of the first clothing wire.
  • the second clothing wire determines the aggressiveness of the all-steel clothing through its positive working angle teeth. This can be increased by the fact that the tooth tips of the second clothing wire project beyond the tooth tips of the first clothing wire, respectively their tip surfaces.
  • the total height of the first clothing wire is smaller by 5 to 50% than the total height of the second clothing wire.
  • the total height of the first clothing wire is preferably 3 to 8 mm.
  • an overall height of the first wire of 4.5 mm has been found to be particularly suitable.
  • For the processing of long staple fibers an overall height of the first wire of 7.5 mm is to be preferred.
  • the tooth pitch of the first clothing wire is greater than the tooth pitch of the second clothing wire.
  • the lengths of the tip areas are co-determined in the first clothing wire.
  • the length of the tip surface is at least 25% of the tooth pitch to achieve the effect of a fiber guide.
  • the length of the tip surface is 50% of the tooth pitch.
  • the length of a peak area increases with increasing pitch. Tooth pitches of 2 to 10 mm have proven particularly suitable for the first clothing wire.
  • the tooth pitch of the second Garniturdrahtes the number of mainly responsible for the fiber transfer peaks increased. This contributes to an increased fiber take-up and allows a high throughput of the corresponding roller.
  • the tip surface angle of the first clothing wire is -5 ° to + 5 °. In a particularly preferred embodiment, the tip surface angle is 0 °, which is equivalent to a tip surface applied parallel to the wire base.
  • the back angles of the first and second clothing wires are the same size. Back angles of 30 to 50 °, in particular 40 °, have proven to be suitable.
  • the distance between the individual tooth tips is determined in the longitudinal direction of the clothing wires by the tooth pitch and in the transverse direction by the foot width of the clothing wire. It has proved to be advantageous if the foot width of the first clothing wire corresponds to the foot width of the second clothing wire.
  • the preferred foot width is 0.5 to 1.5 mm, more preferably 1.0 mm.
  • the all-steel clothing is particularly suitable for licker-in of cotton carding or wool carding.
  • the all-steel clothing is provided on the licker-in roller such that the first clothing wire and the second clothing wire are spirally wound adjacent to each other and alternately.
  • only every third clothing wire can correspond to a first clothing wire on the roller, so that a first clothing wire follows in each case on two adjacent second clothing wires.
  • the first and second clothing wires can be made with normal, locked or interlinked feet to allow mounting on a smooth roller.
  • FIG. 1 shows a schematic representation of an embodiment of a first clothing wire 20 in a view and a cross section at the point XX. It is a sawtooth wire with the teeth 21 with a total height h 1 1 of 4.5 mm and a tooth depth h 6 1 of 2.5 mm.
  • the teeth 21 of the clothing wire 20 are shaped such that a tip surface 24 is formed.
  • the tip surface 24 is designed to incline to the back surface 23 of the tooth 21, creating a positive tip surface angle ⁇ 1.
  • the breast surface 22 of the tooth 21 tilts against its back surface 23, forming a negative working angle ⁇ 1.
  • the teeth 21 of the first clothing wire 20 have a negative working angle ⁇ 1 of 5 ° and a back angle ⁇ 1 of 40 °.
  • the foot width b1 of the first clothing wire 20 is 1.0 mm.
  • the tooth pitch p1 is 4.2 mm.
  • the teeth 21 have a tip surface 24 with a length I1 of 1.3 mm.
  • the tip surface 24 is slightly inclined with a positive tip surface angle ⁇ 1 of + 5 °.
  • Characteristic of the first clothing wire 20 are the negative working angle ⁇ 1 and the tooth shape with a formed tip surface 24, which is guided in its length I1 over at least 25% of the tooth pitch p1.
  • FIG. 2 shows a schematic representation of an embodiment of a second clothing wire 30 in a view and a cross section at the point YY.
  • This is a sawtooth wire with a breast surface 32 and a back surface 33.
  • the breast surface 32 of the tooth 31 tilts with the back surface 33, forming a positive working angle ⁇ 2.
  • the teeth 31 are made in a pointed shape without a tip surface.
  • the sawtooth wire with the teeth 31 has a total height h 1 2 of 5.0 mm and a tooth depth h 6 2 of 2.7 mm.
  • the teeth 31 of the second clothing wire 30 have a positive working angle ⁇ 2 of 10 ° and a back angle ⁇ 2 of 40 °.
  • the foot width b2 of the second clothing wire 30 is 1.0 mm and the pitch p2 is 2.6 mm. Characteristic of the second clothing wire 30 are the pointed tooth shape and the positive working angle ⁇ 2. The teeth 31 may be provided at their top with a side cut.
  • FIG. 3 shows a schematic representation of an embodiment of an all-steel clothing 10 with a first clothing wire 20 with the teeth 21 and a second clothing wire 30 with the teeth 31 in a longitudinal view.
  • the different total height h 1 1 and h 1 2 of the clothing wires 20, 30 can be seen.
  • the teeth 31 of the second clothing wire 30 project beyond the teeth 21 of the first clothing wire 20.
  • FIGS. 4a-4c show a schematic representation of a cross section of an all-steel garnish at the point ZZ of FIG. 3 in different embodiments.
  • a first clothing wire 20 having a foot width b1 and a second clothing wire 30 having a foot width b2 are shown lying side by side.
  • an all-steel garnish in one embodiment is shown with a normal flat foot.
  • This embodiment of the all-steel garniture corresponds to the design used as standard in machines for fiber processing processes.
  • FIG. 4b shows an embodiment of an all-steel clothing with a linked foot, which is used, for example, in openers.
  • Figure 4c shows an embodiment of the all-steel clothing with a locked foot, which is used for example in cleaners.
