Definitions

  • the invention relates to a round comb for a combing machine with a circular-arc carrier, which is rotatably mounted on a shaft and on which are mounted over a portion of its circumference on a body tooth sets.
  • Such round combs are known from the prior art, wherein the clothing is formed from a plurality of sawtooth strips.
  • a circular comb in which on a circular cylindrical support body, a base body is fixed, on the outer surface of sawtooth Ganzstahlgarnituren are attached.
  • the Sge leopardgarnituren be individually and side by side in the respective area mounted on the body, or glued to this. This is a very expensive and expensive process and requires the highest precision both in the production of the individual sets as well as when mounting on the body.
  • the present invention seeks to propose a round comb, in which a simple assembly of Kammgarnituren and their simplified production is ensured.
  • the base body and the toothed fittings are integral and - seen in the direction of rotation of the circular comb - consists of at least two successive clothing elements.
  • the toothed set is completely machined out of the material of the clothing element, whereby a very accurate production of the tooth tips, or the set is made possible.
  • the subsequent installation on the circular comb carrier is greatly simplified by the use of such manufactured clothing elements.
  • the dismantling of a clothing element is also simplified if it has to be replaced with another one.
  • the surface treatment of the individual teeth of the clothing can be simplified by the use of such a clothing element.
  • the rows of teeth of the toothed sets run at an angle (a, b) to the direction of rotation.
  • the choice of the inclined position of the toothed set can be chosen in a simple manner.
  • one or more clothing elements can be provided with slanted rows of teeth. It is conceivable to design consecutive clothing elements with obliquely arranged rows of teeth, the inclination of which runs in the opposite direction in each case.
  • - seen in the direction of rotation - at least one of the clothing elements has a different length than the other clothing elements. It can be provided that - seen counter to the direction of rotation - increases the length of the successive clothing elements.
  • the clothing elements are fastened on the circular comb carrier via a connecting means.
  • the connecting means may be an adhesive, with which the clothing elements are mounted on the circular comb carrier. This type of attachment will be chosen when replacement of the clothing elements is not often provided. Depending on the type of adhesive but also the dismantling and subsequent assembly can also be performed easily.
  • the connecting means is at least one mechanical means, for example, each protruding on both longitudinal sides of the respective clothing element in a recess of the circular comb carrier and the clothing element.
  • the clothing elements on the opposite side of the rows of teeth are provided with extensions, which form a positive connection with correspondingly formed recesses (or openings) in the circular-arc carrier. So that the clothing elements are fixed in their radial position, it is proposed that fastening elements are provided which the extensions fix in the recesses.
  • a fastening method is proposed, wherein the clothing elements on the opposite side of the rows of teeth have at least one extending in its longitudinal direction groove, in which a form-fit engages a sliding block, which is fixable via fastening means with the circular comb carrier.
  • Advantageous for exact fixation is when the groove is dovetailed.
  • the circular comb body is provided with flanges over the area of the clothing elements, in each case adjacent to its two outer ends, wherein the side of the flange which bears axially on the relevant end of the clothing element in the radial direction of the circular comb forms a positive fit Forming connection with the correspondingly shaped end of the clothing element.
  • the individual clothing elements from one side - contrary to the direction of rotation of the circular comb z. B. to thread against an end stop. Subsequently, the clothing elements can be fixed in their position with respect to the direction of rotation of the circular comb via one or more fastening means.
  • the base body and the toothed set are formed in one piece.
  • the adjacent clothing elements can be provided with different geometries of the toothed fittings in the assembled state.
  • the term "different geometries" can be understood as the formation of the tooth shape and its angle of attack, as well as the tooth density and the distance between the rows of teeth, for example. However, there are other possibilities of discrimination possible, which are not all listed here.
  • a round comb 1 of known type is shown, wherein on a circular comb shaft 2 via fastening means, not shown in detail, a circular comb carrier 3 is fixed against rotation.
  • the circular comb carrier 3 can be formed in one or more pieces.
  • a base body 4 is fixed, which extends over part of its circumference.
  • different trained rows of tooth sets 5a - 5d are fixed, in each case the distance between the tooth tips of subsequent clothing segments, for example, is chosen smaller.
  • the toothed sets 5a to 5d form a combing segment 8 as a whole.
  • the toothed sets are either glued to the base body 4 or fastened by means of corresponding receptacles, as has already been described in the introduction to the prior art.
  • Fig. 2 shows a partial view of a combing segment 10 according Fig. 1
  • the combing segment 10 is composed, as claimed according to the invention, of a plurality of clothing elements 6a-6e fastened one behind the other on a round-beam carrier 3.
  • the main body GK is integrally formed with the respective toothed set ZG and - divided into several elements according to the number of different tooth sets. These elements are hereinafter referred to as clothing elements.
