Definitions
- the invention is directed to a clothing for a textile machine comprising a plurality of needles or sawtooth punched parts arranged in rows next to one another, at a distance from one another, the needles or sawtooth punched parts being embossed and accordingly having a non-rectangular cross-sectional geometry, with the needles spaced apart from one another or sawtooth stamped parts, a free passage area is formed for the fibers to be combed.
- Such sets are used for different types of textile machines, e.g. Circular combs, fixed combs, cards etc. are used.
- the object of the invention is to design a set of the type mentioned at the outset in such a way that the cleaning action or combing action is improved.
- this object is achieved in that the free passage area expands in the direction of movement of the sliver.
- the free passage area has a trapezoidal basic shape
- the needles or the tips of the sawtooth stamped parts are shaped in such a way 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 such as shell parts and grains of sand, which can get stuck in conventional trimmings, to be held on only for a short time due to the widening cross section, in that they only abut at the beginning of the passage in the form of lines or dots. It is thus achieved that the clothing remains clean and constant work results are achieved and the fibers are easier to pull through the barrier, ie overall better combing results.
- the long fiber content in the combed decreases and the machine can be optimally adjusted so that the economic aspect improves. This also includes an increased service life due to less stress on the clothing. Ultimately, shell parts, nits and short fibers, which are not pulled off, are retained and jamming of the shell parts is avoided, so that overall a better combing result is achieved.
- the needles or tips are shaped in cross section in such a way that they have convexly convex side surfaces, a rounded front end face seen in the direction of the relative movement to the sliver and a relatively tapering rear end face.
- the needles can have the profile of a symmetrical or asymmetrical aircraft wing in cross section.
- Show: 1 is a partial side view of a row of needles of a set for a machine
- FIG. 7 is a side view of a sawtooth stamped part of a set
- Fig. 8 is a section along the line VHI-VIII in Fig. 7, and
- 9 and 10 are sectional views through a fixed comb with needles, the needles being designed in cross-section like a symmetrical or asymmetrical aircraft wing profile.
- Fig. 1 a series of needles 1 is shown, which are held between two cover plates 2 to form a pinstripe.
- the needles 1 are arranged between the cover plates 2 in parallel and at a distance from one another, a free passage area A remaining between each two needles 1, through which the sliver to be combed is moved in the direction of the arrow 3 shown above FIGS. 2 to 6.
- the needles 1 have an exactly trapezoidal cross-section such that the free passage area rich A between the needles 1 in the direction of movement (arrow 3) of the sliver opens continuously at an angle ⁇ .
- the needles also have a trapezoidal basic shape, but are rounded on the end faces and accordingly taper in the direction of movement (arrow 3) by an angle ⁇ .
- the cross section of the needles 1 is essentially triangular with a taper angle ⁇ of the needle, which is significantly larger than in the embodiment according to FIG. 3, the corners being rounded off with a radius R.
- FIG. 5 and 6 finally show embodiments with an approximately droplet-shaped configuration, where the front end side in the direction of movement (arrow 3) is designed to be strongly rounded and the opposite end side also has a pronounced rounding.
- the taper angle ⁇ is larger than in the embodiment according to FIG. 5.
- Fig. 7 shows a sawtooth punched part 4, a plurality of such sawtooth punched parts 4 being arranged next to one another in a set, for example on the round comb of a machine, such that the tips 5 of adjacent sawtooth punched parts 4 are at a distance from one another and accordingly a free passage A for the Intermeshing sliver is created, with a relative movement between the sliver and tips 5, so that there is a direction of movement corresponding to the arrow 3 in Fig. 8.
- the tips 5 of the sawtooth stamped parts 4 are, as can be seen from FIG. 8, embossed on one side in such a way that they have a bevel at an angle ⁇ on the embossed side and accordingly there is an overall asymmetrical trapezoidal basic shape.
- a section through a fixed comb 6 is shown in sections in FIG. 9 and in FIG. 10, the needles 1 being held between cover plates 2.
- the needles have a symmetrical wing profile in cross section, i.e. starting from a rounded front face 7, the needles are convexly curved outwards in cross section and end with a relatively pointed rear face 8. This ensures that the passage area A of the needles in the area of the free needle board and outside of the cover plates 2 in the direction of the relative movement between needles 1 and fiber sliver (arrow 3), apart from a short area, is continuously expanded at the beginning, flow conditions occurring during movement as on an aircraft wing, which improves the cleaning effect.
- FIG. 10 differs from that of FIG. 9 only in that the cross-sectional profile is asymmetrical, ie the needles have a largely flat or only slightly curved side flank and a convexly curved side flank.
