Embodiment Construction

[0022] The invention is described in greater detail below on the basis of the embodiments shown in the drawings. FIG. 1 shows an opening roll with a rotatably mounted cylindrical roll body and a toothed card clothing. An opening roller is basically known in connection with an open-end spinning device, designated by reference numeral 1 in FIG. 1 , which rotates in a not shown opening roller housing. The task of the opening roller 1 is to break down the fiber strands fed to it by the feed rollers into individual fibers. The individual fibers are then fed into the spinning mechanism (eg spinning rotor) by means of fiber-guiding channels.

[0023] During the spinning process, such opening rollers 1 are usually operated at a rotational speed of 6000 to 12000 revolutions per minute.

[0024] The opening roller 1 has a bearing shaft 2 at the end of which a so-called drive spindle 3 is fastened. A not shown tangential belt acts on the drive spindle 3 during the spinning operation. ...

Abstract

The invention relates to a coating method for the mounting ring (17) of a plucker roller (1) of synthetic fiber materials, which applies at least two layers on the mounting ring (17, 30) via chemical coating. The method comprises steps of: applying a first coating of a nonferrous metal as a base coating on the mounting ring (17, 30); and applying a coating based on a nickel-phosphorus alloy, which does not contain any hardener material as the other layer; then the coated mounting ring (17, 30) is then subjected to heat treatment at a temperature which is below the tempering temperature of the base material of the ring.

Description

technical field [0001] The invention relates to a method for coating an opening roller clothing ring according to the preamble of claim 1 and a clothing ring for an opening roller according to the preamble of claim 9 . Background technique [0002] Various embodiments of the opening rollers of open-end spinning devices are known. Such opening rollers are used to open the fiber sliver into individual fibers before feeding the fiber sliver from the spinning package into the spinning device of the open-end spinning device, which rotates at a high rotational speed. For this purpose, such opening rollers have a tearing structure at their periphery, which cards the supplied fiber strands and in the process opens the fiber strands into individual fibers. In addition, the opening rollers differ in the way their tearing tools, the so-called clothing rings, are constructed. [0003] DE 35 151 53 C2 discloses a clothing ring constructed as a so-called solid ring, in other words made ...
