Definitions

  • the invention relates to a sliver condenser on a textile machine, in particular on a drafting device of a flyer, according to the preamble of claim 1.
  • a sliver condenser on a textile machine in particular on a drafting device of a flyer, according to the preamble of claim 1.
  • Such a device has become known from FR-A-2597119.
  • the flyer drafting systems are fed with fiber bundles or fiber tapes in a parallel orientation, in which they are stretched.
  • These drafting units which have at least one pre-drafting zone and one main drafting zone and therefore three pairs of rollers, produce a fiber sliver on the pair of exit or discharge rollers, the width of which is greater than the height.
  • the twists in the sliver result from the wing revolutions and plant themselves back to the pair of outlet rollers, where the so-called spinning triangle forms.
  • the throat width of conventional condensers which are arranged in the space between the exit roller pair and the aprons of the main draft zone, is determined by optimization in such a way that the lateral narrowing of the sliver becomes as small as possible without creating congestion in the edge areas of the sliver. This is because the width of the sliver emerging from the pair of exit rollers determines the width and indirectly the length of the spinning triangle, which is a sensitive area with regard to sliver or sliver breakage. Due to the importance of a narrow fiber bandwidth, condensing zones are used in some drafting systems. This requires an additional pair of rollers, which now becomes the pair of exit rollers.
  • Fig. 1 shows a four-roll drafting device 4 with a sliver 5, which passes through the pair of rollers 6-7, 8-9, which is equipped with straps 10,11, 12-13 and the exit roller pair 14-15 and that as a fuse or Roving 16 is inserted into a flyer wing 17.
  • the area of the spinning triangle is designated by the reference symbol 18.
  • a pre-draft zone 19, a main draft zone 20 and a condensing zone 21 are formed by the pairs of rollers.
  • the upper rollers 6, 8, 12, 14 are each designed as double rollers and connected to a common, not shown, foldable drafting arm.
  • the lower rollers 7, 9, 13, 15 are connected to one another over the entire length of the machine.
  • the running direction of the sliver 5 or the sliver 16 is indicated by the arrow 22.
  • the condenser 23 according to the invention is preferably arranged in the condensing zone 21 near the pair of outlet rollers 14, 15.
  • FIG. 2 shows a sliver condenser 30, which is usually arranged in the space 24 between the pair of rollers 12, 13 and the straps 10, 11.
  • Two side walls 31, 32 converge in the direction of arrow 22.
  • the smallest distance between the walls 31, 32 is the fillet 33, which in this case is also the light width 34.
  • the light width is understood to mean the greatest lateral extension of a light projection in the direction of arrow 22.
  • the condenser 23 according to the invention likewise has side walls 40, 41, which likewise converge in the running direction of the sliver 5 and form a fillet 42, which is drawn on the same scale for comparison with the condenser 30.
  • the fillet 33 and the fillet 42 are therefore measured at right angles to the running direction of the sliver 5.
  • a channel 43 is arranged at an angle to the direction of travel of the sliver 5 in the running direction of the sliver 5.
  • the wall 40 is rectilinear - a curved or concave wall would also be possible - so that it also forms a side wall of the channel 43.
  • the fillet 42 remains the same size (drawn the same size as the fillet 33), since the other side wall 44 of the channel 43 runs parallel to the wall 40.
  • the light width 45 which is also measured at right angles to the running direction of the sliver 5, is not equal to the throat width 42 in this case, but smaller.
  • the diameter of the fuse 16 corresponds approximately to the light width 45 in the dimensions shown.
  • FIG. 4 shows a sliver condenser in duplicate in position in the condensing zone 21, the condensers 23 and 23.1 being designed in mirror image with respect to the oblique course of the channel 43 and being connected to one another by means of a one-piece holding bracket 53. From FIG. 1, where the holding bracket 53 has been left out for the sake of clarity, and FIG. 5 it can be seen that the regions 54, 55 facing the pair of rollers 14, 15 are adapted to the radii of the rollers 14, 15, so that the sliver condenser is so close can be placed on the pair of rollers 14, 15 as possible. Between the concave regions 54, 55 there is a surface 56 arranged at right angles to the fiber plane, which is at least as high as the thickness of the fiber band 5.
  • the holding bracket 53 has two curved pieces 59, 60 which slide on the cylinders 57, 58, so that the height of the double condenser 23, 53, 23.1 is secured and the two slivers 5 can move the double condenser laterally according to the traversing movement.
  • the bracket should be made of thin steel wire and the condensers 23, 23.1 should be made of plastic. Because of the manufacture and assembly, a one-piece bracket 53 is advantageous.
  • a bevel 61 can be advantageous.
  • the chosen one The fillet width 42 and the height of the surface 56 depend on the circumference of the sliver 5.
