Definitions

  • the invention relates to a set for processing in the form of a sliver supplied fibers can be used and rotated around a rotation axis with at least two circumferential directions of a circular cylinder circumferential surface encircling the axis of rotation successively arranged clothing segments, of which the a rotation of the round comb first engaging in the sliver Engaging segment produces less combing effect than at least one of the Sliver thereafter running through subsequent segments, with at least one of the subsequent segments has a greater length in the circumferential direction than the engagement segment with such a set equipped round comb and such a round comb comber.
  • Equipped with trimmings of the type described above Round combs are used in the processing or finishing of Fibers in combing machines for the separation of short fibers and Nits and shell parts from the already carded raw fiber material used.
  • the combing process turns the stack, i.e. the fiber length of the raw fiber material is standardized.
  • the combing machine is usually between the Card and the track arranged.
  • one is preferably already carded Fibers existing with a fiber sliver a sliver of already combed fibers soldered by held by a pair of pliers and run through by the tines of the circular comb
  • the whole process of engaging the comb teeth in the fiber beard about combing and soldering until intervention of the round comb into a new fiber bit is called "comb play”.
  • Conventional circular combs are essentially cylindrical Carrier body, with the comb over one Part of the cylinder circumference extends.
  • the Combing machine turns the round comb around the cylinder axis and is arranged with respect to the pliers so that the tines of the Comb can pass through the fiber beard held by the pliers, but the support body when turning the circular comb further soldering the combed fiber beard does not hinder.
  • the circular comb is constructed in such a way that on the cylindrical support body, the support body in radial Direction expanding body is attached to which the actual circular comb set is fixed.
  • the object of the invention to provide a set of the type described in the introduction, when used even at high working speeds of 400 combs per minute or more enough time to ensure a satisfactory combing result for soldering the combed fiber beard with an already existing combed fiber Sliver can be provided.
  • This invention is based on the knowledge that a gentle and low damage Intervention of the round comb set in the fiber beard presented already then can be ensured if the engagement segment is only a very small Angle extends in the circumferential direction of the circular comb, so that ensuring a damage-free engagement of the circular comb set by the comparative short engagement segment a large clothing length for the more effective Garnish segments can be provided without doing so increase the total length of the clothing in the circumferential direction.
  • using a set that can overall in the circumferential direction of the circular comb Angles of less than 110 °, preferably less than 100 ° especially preferably extends about 90 ° without damaging the processing fibers achieved a satisfactory combing result become. This means that even at high processing speeds of 400 comb games per minute or more provided enough time for the soldering process can be.
  • the circular comb according to the invention can under Avoiding excessive fiber damage a particularly good combing result with a particularly short clothing length be achieved if the set is at least two, preferably has at least three successive segments, each of which produces a higher combing effect and / or a larger one Has length than the previous following segment or Engaging segment.
  • One is at an angle of less as a 110 °, particularly preferably about 90 °, extending set a satisfactory combing result without damage to fibers possible when the clothing engages in the sliver, when the ratio of the length of the engaging segment to that of the last following segment in the range from 1: 2 to 1: 4 lies.
  • the distance between the tooth tips is of the engaging segment in an elongated arrangement, i.e. before adjustment of the corresponding sawtooth wire to the circular cylinder surface the base body preferably about 4 to 5 mm, particularly preferably about 4.47 mm.
  • Embodiments of the invention with changing intervals between the tooth tips of the individual clothing segments or a variable tooth pitch can be compared to Engagement segment higher combing effect of the following segments also as a result be achieved that the width of the between the sawtooth wire strips of the engagement segment formed lanes in a direction parallel to the axis of rotation is less than the width of the trim alleys at least one of the following segments, preferably all of the following segments.
  • This increase in the combing effect of the following segments can be achieved, for example, in that the foot width of the Sawtooth wire strips of the following segments with the same Blade width compared to that of the engaging segment Sawtooth wire strips is increased.
  • Embodiment of the invention is the foot width of the the sawtooth wire strip forming the engagement segment, for example 0.8 mm, while the following segments a foot width of 0.65, 0.6 or 0.5 mm with the same blade width exhibit.
  • Another additional or alternative way to Increasing the combing effect of the following segments compared to that of the engaging segment is the saw teeth to provide the interventional part with a smaller chest angle, than those of at least one of the following segments, preferably all subsequent segments.
  • the chest angle is the sawtooth wire strips forming the engagement segment in the stretched state, i.e. before mounting on the base body of the round comb, preferably about 30 °, during the Breast angle of the sawtooth wire strips forming the following segments in the stretched state about 35 °, 40 ° and also with the last following segment is still 40 °.
  • the chest angle of all subsequent segments as well as the breast angle of the engagement segment are 30 °.
  • the chest angle of the last subsequent segment up to 55 °, with the Chest angle of the other following segments should be increased accordingly can.
  • the tooth height of the saw teeth of the engagement segment is larger than that of the saw teeth at least one of the following segments, preferably all of them follow segments.
  • sets according to the invention has a round comb made with it an approximately circular cylindrical support body, one over extending part of the circumference of the cylinder and the support body in the radial direction expanding body as well a set attached to the base body, the Set of at least two consecutively arranged in the circumferential direction Set segments with different from each other Combing effects, of which at least one of the following the engaging segment is followed by sliver segments has a greater length in the circumferential direction than that Engaging segment.
  • the circular comb shown in Fig. 1 essentially comprises circular cylindrical support body 10, one in the circumferential direction over part of the circumferential surface of the circular cylindrical shell Carrier body 10 extending and this in the radial direction expanding body 20 and a sawtooth all-steel set labeled 30, which is attached to an outer surface of the base body 20.
  • the from the set 30, the base body 20 and the support body The overall arrangement formed is around the cylinder axis 12 of the carrier body 10 rotatable, as indicated by the arrow 14.
  • the set 30 consists of a total of 4 in the circumferential direction clothing segments 32, 34, 36 arranged one behind the other and 38, of which the hereinafter referred to as the engagement segment Set segment 32 with a rotation in the through arrow 14 direction first in a to be combed Fiber beard engages while the clothing segments 34, 36 and 38 (hereinafter referred to as follow segments) the fiber beard go through in that order.
  • Each of the clothing segments 32, 34, 36 and 38 consists of a plurality of side by side in the direction of the cylinder axis 12 arranged sawtooth wire strips. It stretches the engaging segment 32 in the circumferential direction of the carrier body 10 or the base body 20 over an angle ⁇ of approximately 13 °, the first following segment 34 thereafter over an angle ⁇ of about 15.5 °, the second following segment 36 following the first following segment 34 over an angle ⁇ of approximately 23.5 ° and the third follow segment 38 following the second follow segment 34 over an angle ⁇ of about 38 °, so that the entire set 30 in the circumferential direction over an angle of extends about 90 °. As already shown in FIG.
