Definitions

  • the invention relates to a cover for a card, with a plurality of scratch wires inserted in a pattern in a scraper belt, in which the teeth formed by the scratch wires are arranged in rows in the carding direction and the successive teeth of the tooth rows are offset laterally to the carding direction with an aisle width.
  • cards are used to expose fibers individually and to arrange them into a fleece, and in particular to clean the fiber material in the cotton mill.
  • Such cards generally have a card cylinder which interacts with a cover for processing the fibers.
  • the outer surface of the Kerdenzyiinders and the rods of the cover are provided with teeth, upright wires, pins or needles.
  • Lid sets in rigid, semi-rigid or flexible designs are set in satin, rib or diagonal stitch.
  • these types of setting as seen in the carding direction, there are evenly distributed alleys between the individual teeth, which can have different widths depending on the fineness of the clothing.
  • the carding effect is very strongly influenced by the width of the aisle, especially when processing cotton.
  • With wide streets nits can slip much better between the respective teeth of the cover sets than is the case with narrow streets. This results in an effort to make these streets as narrow as possible.
  • it is not possible to use the types of setting according to the prior art to produce narrow streets as desired because this results in an unfavorable distribution of the teeth of the scratching set, or it is not possible to set too few teeth per unit area. This also has a negative effect on the carding effect.
  • a cover set for a card has become known, in which the teeth are arranged alternately in the carding direction in alternately following left-diagonal stitch and right-diagonal stitch groups.
  • the successive teeth of the rows of teeth are arranged offset to the side of the carding direction with a predetermined lane width, each group having the same lane width.
  • there are immediately successive groups i.e. a respective right-hand diagonal stitch group relative to a respective left-hand diagonal stitch group, or a respective left-hand diagonal stitch group relative to a respective right-hand diagonal stitch group as a whole, offset with respect to one another with an aisle width that is half of the specified aisle width is. This will probably reduce the clear aisle width of the entire lid set, but there will be no lifting of the clear aisle width.
  • DE-A-2 052 898 discloses a cover set in which the tooth limbs arranged one behind the other in the carding direction are at a distance from one another which is at least as large as twice the width of the aisle.
  • the teeth form chains running diagonally to the carding direction, two adjacent chains being arranged so that they are offset from one another in such a way that the teeth of the chains alternate in this order.
  • the purpose of this arrangement is a loosening of the lane boundary in the carding direction, which should lead to a relatively strongly changing lane width, so that firmer fiber flakes or shell pieces can escape into the wider areas of the lane widths.
  • the aim is also not to remove the clear aisle width.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a cover for a card, in which there are no clear aisle widths even with low and high tooth density
  • FIG. 1 shows a satin stitch according to DIN 64108.
  • the teeth of a row R are distributed such that a lane width g 1 is one third of the web width e.
  • the carding direction is indicated by the arrow K, which direction is the same for all the figures shown.
  • 2 shows a rib stitch according to DIN 64108, the teeth of a row R being distributed such that the web width e is equal to the tooth spacing a, as in the left one Side of FIG. 2, a lane width g 1 is present.
  • 3 shows the diagonal stitch according to DIN 64108.
  • the teeth of a row are distributed so that the web width e is equal to the tooth spacing a.
  • the teeth of the next row R ' are offset by one third of the web width from the previous row R. From the left side of FIG. 3 it can be seen again that an aisle width 91 is present.
  • the aisle width 91 is larger than the wire thickness.
  • This slip is prevented according to the invention in that the alley width g 1 is not more than the wire gauge.
  • a cover set with a plurality of groups of rows of teeth is seen in the carding direction K in FIG. 4.
  • 4 shows two successive groups, the group preceding in the carding direction being designated with the reference number 1 and the immediately following group with the reference number 2. Both groups have the same pattern, here a diagonal stitch.
  • the last row of teeth of the preceding group 1 is denoted by R "and the first row of teeth of the following group 2 is denoted by R '".
  • the teeth of the first row R '"of the following group 2 are seen in the carding direction K relative to the teeth of the last row R" of the preceding group by a distance G ". This distance G" in FIG.
  • FIG. 5 shows a cover set which corresponds to the embodiment according to FIG. 4, but three groups 11, 12, 13 of the same pattern are drawn, each group having seven rows R of teeth.
  • the teeth of the respective first row R "" of a group 12 or 13 following in the carding direction is in relation to any row of teeth of a preceding group 11 or 12, here e.g. the row of teeth R "is displaced by a distance which corresponds at most to the respective wire thickness of the scraper wire.
  • the teeth of the first row of teeth R" "are one distance in relation to the immediately preceding, last row of teeth R '" of the respective preceding group shifted or offset, which is greater than the respective wire thickness. This prevents the scratch carrier from tearing at the point between two successive groups of staggered arrangement.
