Definitions

  • the invention relates to a sawtooth wire for producing a sawtooth all-steel set as they are used for various purposes in the textile processing process such as for a combing machine, in particular for a wool comb, with a Foot section and a preferably adjoining it via a foot shoulder Leaf section, wherein the leaf section through from the edge facing away from the foot section of the blade section has outgoing incisions formed saw teeth, one under Use of such sawtooth wires manufactured sawtooth all-steel set and a Combing machine, card, tearing machine manufactured using such a set, Pre-dissolving machine and in particular a wool chamber.
  • Combing machines are used in the processing of textile fibers for cleaning and parallelization of the fibers used.
  • the fiber material of the combing machine can be in the form of a If necessary, already carded beard must be presented. This fiber beard is encircled by a Pass through the combing machine set, from the not yet combed sliver separated and connected or soldered to already combed fibers.
  • the invention is based on the object to provide a sawtooth wire with a better cleaning effect
  • Sets can be produced as well as corresponding sets and combing machines specify.
  • This invention is based on the knowledge that the poor cleaning effect Known combing machines is primarily due to the fact that between the individual Saw tooth wires formed are so wide that fine lining particles and small nits can no longer be combed out.
  • Sawtooth wires manufactured sets in which the set feet side by side arranged sawtooth wires lie directly against each other, the width is the clothing lanes in the area of the clothing base adjacent to the foot less than 0.25 mm, so that even very fine impurities can be combed out, whereby A further improvement in the cleaning effect is achieved if the difference between the foot width and the sheet width at the foot is 0.15 mm or less, so that the Width of the clothing alleys in the clothing base adjacent to the foot is a maximum of 0.15 mm is.
  • the ratio the foot width to the sheet width at the foot is less than 2, preferably less than 1.75.
  • a further improvement in the cleaning effect using the inventive Sawtooth wires produced sets can be achieved if the difference between the Blade width at the foot and blade width at the tip less than 0.2 mm, preferably less than 0.15 mm, particularly preferably less than 0.1 mm, because then also in the range the tooth tips of the sawtooth all-steel set is another for combing out fine impurities enough narrow alley width is obtained.
  • Sawtooth wires are usually used to manufacture a set with the help of guide elements, such as guide rollers or rollers, resting on the foot shoulders mounted a clothing rack.
  • guide elements such as guide rollers or rollers
  • the foot width is at most 0.7 mm, preferably at most 0.35 mm, particularly preferably at most 0.3 mm, while the blade width at the tip is at most 0.2 mm, preferably at most 0.15 mm, particularly is preferably at most 0.1 mm.
  • the total height of the wire is expediently more than 4 mm, preferably about 5.5 mm, while the foot height is less is less than 2 mm, preferably less than 1.5 mm, particularly preferably about 1.2 mm and / or the incision depth is about 4 mm.
  • a sawtooth wire according to the invention also has manufactured set of a plurality of saw tooth wires arranged side by side on, the foot flanks of these sawtooth wires arranged side by side abut each other directly.
  • One made using such trimmings Combing machine comprises an approximately circular-cylindrical and rotatably mounted about the cylinder axis Base body with a plurality of arranged one behind the other in the circumferential direction Set elements, each set element a set carrier and a plurality of sawtooth wires arranged side by side thereon.
  • the use of separate on a base body mountable trim elements has the advantage that different Comb elements producing combing effects are installed independently of one another and can be exchanged.
  • a clothing element arranged in the circumferential direction behind a clothing element is a larger one Combing effect (progressive combing effect) brings about as a previous clothing element.
  • a further protection of the fiber material can be achieved if before in the circumferential direction or direction of rotation of the base body of the first clothing element, a deflection element is arranged with which the fiber beard with respect to a cylinder axis of the base body Rotation of the base body about the cylinder axis can be deflected radially outward.
  • sawtooth wires and sets according to the invention consists essentially of a foot portion 20 and a sheet section 30.
  • the foot section 20 becomes the sheet section 30 facing away from a substantially flat lower boundary surface 24, of which two foot flanks 26 and 28 enclose a right angle go out and extend towards the sheet portion 30.
  • Base section is achieved that the sawtooth wire shown in Fig. 1a on a clothing carrier can be mounted with a smooth support surface, next to each other on the support surface arranged sawtooth wires are arranged so that the flank surfaces of the foot sections abut each other, as shown in Fig. 2a.
  • This guide groove extends over more than half of the total foot height, the groove depth is less than half the foot width.
  • the foot section merges via a foot shoulder 22 into the sheet section 30, which is provided with a number of teeth 32.
  • the teeth 32 are formed by tooth incisions extending from the edge of the blade section 30 facing away from the foot section 20 in the direction of the foot section 20.
  • the width of the foot shoulder 22, ie the difference between the foot width b 1 and the sheet width b 2 at the foot, is approximately 0.15 mm.
  • the foot flank 28 is coplanar with the flank of the blade 30 adjoining it. Accordingly, the width of the clothing line between two adjacent sawtooth wires is in the region of the alley base adjacent to the foot in the one shown in FIG. 2a Set about 0.15 mm.
  • the sheet width b 2 of the peak is about 0.08 mm, while the base width b 1, is 35 mm, so that the width of the clothing streets in the area of the tooth tips is about 0.27 mm.
  • the individual saw teeth of the saw tooth wire shown are designed in the form of so-called arch teeth, the chest angle ⁇ being approximately 45 ° and the back angle ⁇ being approximately 60 °.
  • the radius of curvature of the tooth face R is approximately 3.5 mm.
  • the total height h 1 of the wire is approximately 5.5 mm, the base height h 2 approximately 1.2 mm and the tooth incision depth h 6 approximately 4 mm.
  • the sawtooth wire shown in FIG. 1b differs only from that on the basis of that 1a and 3 sawtooth wires that the foot flank 26 is seamless, i. merges into the adjacent leaf flank without the foot shoulder, so that the width of the clothing lanes in the set shown in Fig. 2b starting from the tooth tips in Direction towards the foot sections of the sawtooth wires steadily reduced to 0.
  • the third embodiment of the invention shown in FIG. 4 differs essentially only from the first embodiment of the invention explained with reference to FIGS. 4a and 3 in that the foot flank 26 is realized smoothly, ie without a corresponding groove being made therein.
