Definitions

  • the invention relates to a round comb of a combing machine with a round comb roller, which carries a comb set with one or more comb segments, which form an outer enveloping circle.
  • a round comb of a combing machine with a round comb roller, which carries a comb set with one or more comb segments, which form an outer enveloping circle.
  • the fiber beard projecting from a pliers unit and held in place by means of pliers lips is combed out by means of a circular comb arranged underneath the pliers.
  • the pliers unit which performs a reciprocating movement, is in a rear and closed position when combing out.
  • Combing is carried out with a comb segment, which is attached to a partial section of the circumference of a comb roller.
  • the radius, which the comb segment defines through its enveloping circle, is larger than the radius of the comb roller. Since the comb segment is located only on a partial section of the circumference of the circular comb roller, the pliers lip of a lower pliers plate or the upper pliers plate can be swung into this envelope circle of the comb segment when swiveling forward when a combing interval has ended. If the pliers are in their front position, they are open and transfer the combed fiber beard to a pair of tear-off rollers, whereby soldering is carried out with the fiber beard which has already been torn off.
  • a comb unit also sticks into the fiber beard to be torn off and supports the separation of undesired components, e.g. nits, shell parts or the like. from the fiber beard to be torn off.
  • the cotton wool connected to the fiber beard to be torn off and located in the forceps unit is retained via the nip point of a feed roller or other aids.
  • a short distance ensures that the fiber beard which is subsequently to be torn off can be gripped and combed out to a relatively short distance by the combing segments.
  • the best case would be achieved if the enveloping circle of the combing segments touched directly and without distance to the pliers lip of the top pliers plate.
  • this leads to damage and partly to the destruction of the pliers lip of the upper pliers plate.
  • the object of the invention is therefore to design or fasten the combing segment or segments in such a way that optimal combing out of the fiber beard is ensured, damage to the pliers assembly being excluded.
  • At least one comb segment consists of non-metallic, flexible material in the case of several comb segments. This makes it possible Tanging the flexible combing segments with the pliers lip of the top pliers plate without damaging the pliers lip. It can only happen that the combing segment made of non-metallic, flexible material is worn out, which, however, is relatively easy to replace as a wearing part.
  • the enveloping circle of the combing segment made of plastic is chosen to be larger than the enveloping circle of the metallic combing segment.
  • the combing segment made of plastic In order to increase the combing-out effect, it is proposed to arrange the combing segment made of plastic after the combing segment made of metallic material. To make it easier to replace the combing segment made of plastic, it is proposed to attach it to the circular comb roller or to a base body mounted on the circular comb roller by means of an adhesive connection or a double-sided adhesive strip.
  • the non-metallic and flexible combing segment As an alternative to the combing segment made of plastic, it is also proposed to design the non-metallic and flexible combing segment as a bead.
  • the bead is designed to be flexible in itself and can be connected from a correspondingly shaped cross section to the circular comb roller or to the base body mounted on the circular comb roller.
  • the connection can also be provided as an adhesive connection.
  • the bead has the property that when the circular comb rotates, the centrifugal forces that occur cause the bead to deform radially outward. This is one exact adjustment to the position of the pliers lip of the upper pliers plate possible. At the same time, a deflection of the flexible bead is guaranteed when it hits the pliers lip of the upper pliers plate. This prevents excessive wear and tear on the bead or the textile material on the bead.
  • the nits and other impurities still present in the fiber beard are to be combed out by the bead or the textile fabric.
  • FIG. 1 shows a round comb roller 1 with a comb set 4.
  • the comb set 4 consists of a base body 2, which is fastened on the round comb roller 1.
  • the comb segments 3a, 3b and 3c and a bead 7 are fastened on the base body 2.
  • the comb segments 3a to 3c are made of metallic material, e.g. made of steel, whereby viewed against the direction of rotation of the circular comb, the individual comb segments can have different or increasing needling.
  • the outer tips of the comb segments 3a-3c describe an envelope radius R1. At the comb segments 3a, 3b and 3c there is a bead 7, the envelope radius R2 of which can correspond to the envelope radius R1 when the circular comb roller is at a standstill.
  • the envelope radius R2 can increase and thus adapt to the position of the pliers lip 16 of the upper pliers plate 10, i.e. the distance between the bead and pliers lip 16 can be reduced to zero.
  • the bead 7 here consists of a closed or open kidney-shaped or elliptical textile material which is fastened to the base body 2 via an adhesive connection or other connection.
  • the textile fabric of the bead 7 is constructed in such a way that the protruding e.g.
  • fibers or filament loops consisting of filament can engage in the fiber beard 14 in a combing effect. It is also conceivable to e.g. train in loop form.
  • the handle of the textile fabric must have a corresponding roughness so that a combing effect or combing out e.g. can be made by nits or similar components.
  • FIG. 2 essentially corresponds to that in FIG. 1 except for the use of different comb segments.
  • a comb segment 4 made of plastic is arranged in the example according to FIG. 2 following two metallic comb segments 3a and 3b.
  • the needling of the comb segments 3a, 3b and 5 can be designed to rise towards the rear, as seen against the direction of rotation of the circular comb 1.
  • the envelope radius R2 of the tips of the comb segment 5 is larger than the envelope radius R2 of the two metallic comb segments 3a and 3b. This also makes it possible to reduce the distance between the enveloping circle with the enveloping circle radius R2 of the plastic segment to the pliers lip 16 of the upper pliers plate 10 to a minimum to a distance of zero.
  • FIG. 3 shows only a partial section on an enlarged scale from FIG. 1.
  • FIG. 4 corresponds to the construction of the exemplary embodiment according to FIG. 1 except for the choice of the different comb segments.
  • 3 different comb segments are arranged one behind the other on the base body 2.
  • the first combing segment is formed from a metallic combing segment 3a, which is followed by a combing segment 5 made of plastic.
  • the radius R2 of the enveloping circle of the combing segment 5 is larger than the radius R1 of the enveloping circle of the combing segment 3a.
  • the enveloping circle radius R3 of the enveloping circle of the hollow profile 12 with textile fabric 13 can be greater than or equal to the enveloping circle radius R2.
  • the hollow profile can also be connected to the base body 2 via an adhesive connection.
  • the hollow profile 12 is made of plastic or one Made of rubber material.
  • a spoiler 6 follows the base body 2, as already described in the previous examples. The combing-out process is carried out as described below:
  • a cotton wool 15 is pulled off a cotton roll (not shown) and fed to the forceps mouth 8 of a forceps to and fro via a feed cylinder 11. If the pliers are in a rear position with respect to the tear-off cylinders (not shown), the pliers jaw 8 closes and the two pliers plates 9 and 10 clamp the cotton wool 15.
  • the protruding part of the cotton wool 15 is generally referred to as a fiber beard. Due to the corresponding shape of the pliers lip 16, the fiber beard 14 points in the direction of the axis of rotation of the circular comb roller 1.
  • the fiber beard 14 As soon as the fiber beard 14 meets the comb set 4, it is raised and pulled through between the needling of the comb segments.
  • the short fibers located in the fiber beard and not clamped, as well as the impurities in the fiber beard, such as nits or the like, are combed out. These combed components, also called noils, are given off by the comb set to a cleaning roller arranged below the circular comb and not shown in detail.
  • the pinched part of the fiber beard 14 located in the pliers mouth cannot be grasped by the comb set 4, so that during the subsequent tear-off process an additional fixed comb which can be fed into the fiber beard from above and which pierces the fiber beard is necessary.
