Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The invention is described below with reference to one exemplary embodiment, and is explained in greater detail by use of the drawings.

[0018] FIG. 1 shows a schematic illustration of one embodiment of a clothing wire; and

[0019] FIG. 2 shows a schematic illustration of a cross section of a clothing wire.

DETAILED DESCRIPTION

[0020] Reference will now be made to embodiments of the invention, one or more examples of which are shown in the drawings. Each embodiment is provided by way of explanation of the invention, and not as a limitation of the invention. For example features illustrated or described as part of one embodiment can be combined with another embodiment to yield still another embodiment. It is intended that the present invention include these and other modifications and variations to the embodiments described herein.

[0021] FIG. 1 shows a schematic illustration of one embodiment of a clothing wire 1 having a root 2 and a blade 3. In this embodiment, the root 2 and the blade 3 extend over the overall height h.sub.1 of 7.5 mm. The blade 3 is provided with teeth 4 which are situated in succession along the clothing wire 1 at specific intervals, the so-called tooth pitch p. The teeth 4 have identical shapes, and are regularly arranged along the clothing wire 1 with a tooth pitch p of 10 mm.

[0022] The teeth 4 have a tooth depth h.sub.6 of 4.5 mm, and on the side facing away from the root 2 end in a first tip 5 and a second tip 6. The tooth depth h.sub.6 extends from the first tooth tip 5 to the tooth base 8. The first tip 5 is joined to the second tip 6 via a concave tip face 7. In the exemplary embodiment shown according to FIG. 1, the concave tip face 7 is designed with a circular recess having a radius D of 3 mm. At the location of the second tip 6, the tooth 4 has a lower tooth depth than the tooth depth h.sub.6 at the location of the first tooth tip 5. This difference in height between the second tooth tip 6 and the first tooth tip 5 results in a height difference E of 0.02 to 0.5 mm. The height difference E results from a lower overall height of the clothing wire 1 at the location of the second tip 6 compared to the overall height h.sub.6 at the first tip 6 of the tooth 4. The tooth base 8 is always the same distance from the root 2.

[0023] The tooth 4 has a tooth length C of 3.5 mm, the tooth length C corresponding to the distance from the first tip 5 to the second tip 6 of the tooth 4. The so-called front face 9, which, viewed in the direction of movement, leads from the tooth tip 5 to the tooth base 8, represents the front tooth face. The working angle is the angle between the front face 9 and the vertical axis of the wire base. Viewed in a first working direction X, the working angle is illustrated to be 10, and in a second working direction Y the working angle is likewise illustrated to be 10. The front face 9, viewed in the first working direction X, with a tooth base radius G of 2 mm, is joined to the tooth base 8. Viewed in the second working direction Y, a tooth base radius of likewise 2 mm is provided. The exemplary embodiment shown thus represents a tooth 4 having a symmetrical shape, disregarding the height difference E between the second tip 6 and the first tip 5.

[0024] FIG. 2 shows a schematic illustration of a cross section of a clothing wire 1 in various embodiments. A clothing wire 1 having a root 2 and a blade 3 is illustrated in all embodiments. The blade 3, starting from the root 2, tapers to a blade width b.sub.3 of 0.8 mm at the first tip 5.

[0025] A clothing wire 1 in an embodiment having a normal flat root 2 is illustrated in the left diagram of FIG. 2. This embodiment of the clothing wire 1 corresponds to the standard design used in machines for fiber processing processes. The middle diagram shows an embodiment of a clothing wire 1 having a concatenated root 2, which is used in openers, for example. The right diagram shows an embodiment of the clothing wire 1 having an interlocking root 2, which is used in cleaners, for example.

[0026] Modifications and variations can be made to the embodiments illustrated or described herein without departing from the scope and spirit of the invention as set forth in the appended claims.
