  • WO03087446A2 and DE1927049A1 show gear wires with tooth tips that are arranged at a uniform distance, but in which the tooth depths between successive tooth tips are alternated or of different depths.
  • the clothing wire according to the invention has a foot section which is designed to be arranged with its underside, which is arranged at one end of the clothing wire in its vertical direction, on the surface of a clothing carrier of a carding machine.
  • a clothing carrier of a carding machine such as a card or a carding machine is, for example, a roller, a flat bar of a revolving flat or a fixed cover element.
  • the clothing wire is naturally wound up in a spiral manner, while on cover elements it can also be arranged in a stretched manner.
  • the longitudinal direction of the clothing wire is the direction in which the stretched clothing wire extends in principle endlessly.
  • the teeth extend perpendicularly from this longitudinal direction and perpendicularly to the underside of the foot section, which lies in one plane when the clothing wire is stretched, in a so-called height direction away from the foot section.
  • the third, vertical spatial direction is referred to as the width direction.
  • the foot section can also serve, for example, with lateral outer surfaces pointing in the width direction, to support adjacent turns of the same wire.
  • rectangular or linked foot sections can be advantageous.
  • the foot section can be wider in the width direction than the blade section so that the necessary channels for the fibers are present between the teeth in the width direction.
  • the foot section has a foot height in the height direction.
  • the clothing wire according to the invention has a blade section, on which the end of the clothing wire opposite the underside is formed in the height direction.

  • the blade section has a blade height in the height direction.
  • the sum of the blade height and the foot height can be the total height of the clothing wire.
  • the delimitation of the blade section from the foot section can be as follows: In the case of a non-linked, rectangular foot section, the foot section ends at the top at the point at which the extension of the clothing wire in the width direction begins to become smaller. In the case of a linked foot section, the foot section can end at the top in a flat surface that is parallel to the underside of the foot section.
  • the upper limit of the foot section must be determined in accordance with the functions of the foot section outlined above.
  • the blade section can be designed to widen towards the bottom, whereby the widening towards the bottom can be rather small and linear near the tooth tips, while the widening to the maximum width can be faster near the foot section.
  • the foot section can begin at the point where the blade section has reached a maximum width.
  • the blade height of the clothing wire according to the invention is greater than the foot height. This allows, on the one hand, deeply punched tooth spaces to be formed in the blade section, which provide a large volume for accommodating a large number of fibers. On the other hand, a foot area is created which is well suited for winding onto a roller in a spiral manner.
  • the blade section of the wire clothing according to the invention has a plurality of identical tooth bodies following one another in the longitudinal direction.
