Definitions

  • the invention relates to a card clothing for a card with teeth inserted into a scraper belt, each consisting of two protruding tooth limbs which are connected to one another by a toothed web lying transversely to the direction of the fiber passage, with several teeth forming an ordered group of teeth arranged diagonally to the direction of fiber passage, the teeth of which are offset from one another are arranged so that the offset, ie the distance measured transversely to the direction of fiber travel, of the left and right tooth legs of two adjacent teeth in a diagonal group is always the same size and that diagonal groups of teeth in the direction of fiber travel partially overlap one another.
  • the object of the invention is to improve a lid set of the type mentioned in such a way that small alley widths are achieved even with a relatively large offset.
  • the offset is selected in size so that after an even number of rows of teeth, and thus after an odd number of offsets of a diagonal group of teeth, only the right or left leg of the first or last tooth of this straight Number aligned with the right or left leg of a last or first tooth of the even number of an adjacent diagonal group of teeth in the direction of fiber passage.
  • This diagonal stitch differs from the diagonal stitches known from DIN 64108 by the odd number of offsets. This ensures that the left leg of the teeth of a leading row of teeth, seen in the direction of fiber travel, are not under the right leg of one of the trailing rows of teeth. In this way, despite a relatively large offset, small lane widths can be produced with an even distribution of the teeth.
  • Each tooth of a cover set for a card consists of two tooth limbs 1, 2 projecting vertically from the carrier material 3, which are connected to one another on the back of the carrier material by a toothed bridge 4. These toothed webs are always transverse or perpendicular to the direction of fiber travel (F).
  • the tooth limbs 1, 2 of the teeth 5 of a diagonal group of teeth 6 are aligned in the direction F with the legs 1, 2 of an adjacent diagonal group of teeth, so that equally large streets g2 with a clear width g be achieved, the width of which depends on the size of the offset v, so that the offset directly determines the size of these streets and thus must be chosen very small in order to reach small streets.
  • the offset V in the direction F is always subdivided by a tooth leg 1, 2 of an adjacent diagonal group of teeth 6, so that a smaller, in particular half the width of the aisle g 1 is always achieved as the size of the offset v is.
  • This is achieved by always placing an even number of rows and thus an odd number of offsets within a diagonal group of teeth.
  • the left or right tooth limbs of the teeth of a leading row of teeth seen in the direction of fiber passage are not under the right or left tooth limbs of one of the trailing rows of teeth, so that narrow streets can be achieved despite a relatively large offset.
  • the lid assembly shown in Fig. 4 consists of two groups with different pitches, the group 8 preceding in the fiber passage direction has a smaller offset and thus a larger slope than the group 9 following in the fiber passage direction.
  • Group 9 has a smaller lane, since it was manufactured according to the inventive concept set out in main claim 1.
  • narrow streets are narrowed in groups. This has the effect that the coarser impurities are eliminated in the front groups due to the larger alleys and the fine impurities in trailing groups due to the smaller alleys.
