Definitions

  • the present invention relates to the field of fiber treatment by combing and relates to a circular brush for a straight combing machine.
  • the short fibers are separated from the long fibers by a circular comb and by a fixed comb.
  • the circular brush penetrates into the barrettes of the circular comb in order to extract the blister therefrom and bring it to the doffer.
  • the circular brush has a higher speed of rotation than that of the circular comb, in order to achieve effective cleaning of the latter.
  • the tufts of the circular brush are pushed back and, after a certain period of operation, these tufts remain in the folded back position so that the effectiveness of the circular brush is almost zero, the tufts no longer penetrating between the barrettes of the circular comb and no longer taking out the brush.
  • the present invention aims to overcome these drawbacks.
  • Figures 1 and 3 of the accompanying drawings show a set of circular comb 1, circular brush 2, doffer 3 or comb and comb 4 detacher of the sleeve of a straight combing machine.
  • the circular brush 2 of a straight combing machine is characterized in that its tufts 5 are located in housings 6 inclined in the direction of its direction of rotation and in that, during rotation, it cooperates with a device 7 for cleaning and straightening the tufts 5.
  • the tufts 5 are located in the housings 6 which are arranged in the body of the circular brush 2.
  • the housings 6 are advantageously inclined with respect to the radius of an angle of between 5 ° and 30 ° in the direction of the direction of rotation (figure 2).
  • the bush which is brought by the circular comb 1 which rotates in the direction of the arrow 8, is taken up by the circular brush 2 which rotates in the direction of the arrow 9 and has a faster circumferential speed than that of the circular comb 1.
  • the doffer or comb 3 which rotates in the direction of the arrow 10 and at a circumferential speed slower than the circular brush 2, picks up the sleeve of the latter and is discharged during rotation by the detacher comb 4, animated by an oscillating movement in the direction of the double arrow 11, this comb 4 causing it to fall into the comb tray of the comber (not shown).
  • the device 7 for cleaning and straightening tufts 5 is advantageously constituted, as shown in Figure 1, by a hammer 12 with one or more heads which rotates, according to arrow 13, so as to mesh with the tufts 5 of the circular brush 2, that is to say in the same tangential direction .
  • the hammer 12 taps on the tufts 5 which pass in front of it and straightens them so that they are again straight and of attack for the next cleaning round of the circular comb 1.
  • the hammer 12 also contributes to maintaining the cleanliness of the circular brush 2 by a cleaning effect of the tufts 5 constituting it.
  • Figures 3 and 4 of the accompanying drawings show an alternative embodiment of the invention, in which the device 7 for cleaning and straightening the tufts 5 is constituted by a compressed air jet installation comprising a duct 14 for supplying compressed air and blowing nozzles 15 directed towards the tufts 5, the conduit 14 being driven back and forth parallel to the axis of the circular brush 2 along arrow 16 ( Figure 4).
  • This embodiment allows straightening and cleaning by cleaning the tufts 5 during the rotation of the brush 2, so that the latter is continuously attacked for the next cleaning round of the comb 1 and is maintained in a state perfect cleanliness.
