Definitions

  • the present invention relates to the field of the textile industry, in particular the rectilinear combers and relates to a combing process and a combing machine for carrying out this method.
  • the combing cycle of modern rectilinear combers which are derived from models dating back to the middle of the 19 th century, is well known and can be broken down into two phases, the first of which is called combing of the fiber heads and the second of combing the tails of fibers.
  • the combing phase of the fiber heads occurs when the clamp is closed, while the combing phase of the fiber tails occurs at the time of tearing, when the clamp is open.
  • the combing phase of the fiber heads is carried out by a segment of needles or teeth arranged on a part of the periphery of a rotary cylinder, commonly called a circular comb, whereas the combing phase of the fiber tails is carried out by a comb commonly called fixed or straight comb.
  • the circular comb whose axis of rotation is fixed relative to the frame of the machine, performs a complete revolution per machine cycle.
  • This circular comb is a cylinder, a part of the periphery of which is provided with a segment filled with needles or teeth with increasing density relative to the direction of rotation of the cylinder and which will be used to clean the fiber heads exceeding of the pliers during the combing phase of the heads.
  • the speed of the circular comb is successively accelerated and then slowed down during a complete cycle of the machine.
  • the other part of the periphery of the cylinder is not provided with needles but is smooth and recessed because the presence of needles on this part of the cylinder is not necessary at the time of pulling and the fact that space must be provided for the mechanical elements in motion during the tearing operation.
  • the needles of the circular comb can be mounted only on a part only of the surface of the cylinder which carries them ( FR-A-2 114 192 ) and, on the other hand, there is a risk of collision between the circular comb and the lower clamp jaw, which is part of mechanical movements, during the tearing operation ( EP-A-0 936 292 ).
  • the segment is usually filled with needles of increasing density ( FR-A-1 209 191 ), so as to ensure progressive combing of the fiber heads.
  • the first needle bars are filled with needles of large dimensions and widely spaced while the last needles are trimmed needles thinner and tight.
  • the circular comb needle segment is cleaned by a cylindrical brush ( FR-A-2,651,512 ) which is itself broken by a doffer cylinder, which is in turn discharged by a beating comb.
  • the rotational speed of the cylindrical brush whose direction of rotation is opposite to that of the circular comb, is greater than that of the circular comb.
  • the impurities preferentially accumulate between the first needles or teeth brought into contact with the textile material and then between needles or teeth the finest and the tightest. This results in a gradual degradation of the cleanliness of the combed ribbons.
