Definitions

  • the invention is directed to a clothing for a textile machine comprehensively a plurality of in rows next to each other, spaced apart Arranged needles or sawtooth punched parts, the needles or Sawtooth stamped parts are embossed and accordingly a non-rectangular Have cross-sectional geometry, being between the spaced apart Needles or sawtooth stamped parts have a free passage area is formed for the fibers to be combed (GB-A-1 187 273).
  • Such sets are used for different types of textile machines, e.g. Circular combs, fixed combs, cards etc. are used. It is in already known in this context, by embossing, i.e. by Cold forming, at least the needles or the tips of sawtooth stampings partially deformed so that the originally round or rectangular Change cross-sectional configuration.
  • the object of the invention is a set of the type mentioned in such a way that the cleaning effect or combing effect is improved.
  • This object is achieved in that the free Passage area seen in the direction of movement of the sliver steadily extended.
  • the free Passage area has a trapezoidal basic shape
  • the Needles or the tips of the sawtooth stampings are so shaped that they have a triangular or trapezoidal basic shape in cross section.
  • triangle corners or trapezoid corners are favorably rounded.
  • the configuration according to the invention makes it possible for impurities like shell parts and grains of sand that are found in conventional Sets can only fix through the widening cross section be held briefly by just at the beginning of the passage point or line.
  • the needles or tips are shaped in cross section so that they are convexly convex outwards Have side surfaces, seen a rounded front end face in the direction of relative movement to the sliver and a relative tapered rear face.
  • the needles can have a profile in cross section Have symmetrical or asymmetrical aircraft wing.
  • Fig. 1 a series of needles 1 is shown, which between two Cover plates 2 are held with the formation of a pinstripe.
  • the needles 1 are parallel and spaced between the cover plates 2 arranged from each other, a free one between each two needles Passage area A remains through which the sliver to be combed in Direction of the arrow 3 shown above FIGS. 2 to 6 moves through becomes.
  • the needles 1 have an exactly trapezoidal shape Cross section such that the free passage area A between the needles 1 in the direction of movement (arrow 3) of the sliver opens continuously with an angle ⁇ .
  • the needles also have one trapezoidal basic shape, but are rounded on the front sides and accordingly taper in the direction of movement (arrow 3) by one Angle ⁇ .
  • the cross section of the needles 1 essentially triangular with a taper angle ⁇ of the needle, which is significantly larger than in the embodiment of FIG. 3, the Corners with a radius R are rounded.
  • Fig. 7 shows a sawtooth punched part 4, where in a set, e.g. on the Round comb of a machine, a plurality of such saw tooth punch parts 4 is arranged side by side such that the tips 5 are side by side Sawtooth punched parts 4 are at a distance from one another and accordingly a free passage A for the sliver to be combed is created, with a relative movement between the sliver and Tips 5 arises so that there is a direction of movement corresponding to the Arrow 3 in Fig. 8 results.
  • the tips 5 of the sawtooth punched parts 4 are, as can be seen from FIG. 8, one-sided embossed in such a way that it has a bevel on the embossed side have an angle ⁇ and, accordingly, a total of one asymmetrical trapezoidal basic shape results.
  • the needles have a cross section a symmetrical wing profile, i.e. starting from one rounded front end 7, the needles are convex in cross section arched outwards and end with a relatively pointed rear end 8. This ensures that the passage area A of the needles in Area of the free needle board and outside of the cover plates 2 in Direction of relative movement between needles 1 and sliver (arrow 3) apart from a short area at the beginning, constantly expanding, with the movement creates flow conditions like on an airplane wing, which improves the cleaning effect.
  • Fig. 10 differs from that Fig. 9 only in that the cross-sectional profile is asymmetrical, i.e. the needles have a largely flat or only slightly curved side flank and a convexly curved side flank.
