Definitions

  • This invention relates to pinned components, e.g. for treating textiles and other fibers and is particularly applicable to pinned textile carding, combing and opening equipment and to pinned opening rollers for open-end spinning machines and to pinned combing elements for half lap combining machines and rollers or segments of rollers for carding apparatus, and to a method of treating the pinned components to improve their performance.
  • pinned components often have an essentially cylindrical or part-cylindrical metallic body presenting a surface covered with pin points.
  • These pin points are formed by mounting or setting suitably hardened or tempered steel pins known in the trade as textile pins, within drilled apertures in the body. The pins are often held in place with the aid of a polymer adhesive.
  • the surface for receiving the pins has to be machined and drilled, it is liable to be marked by burrs and other irregularities, and these can cause snagging of the textile material being treated by the component. Also, cured or part cured adhesive can remain on the surface, especially around the pin roots. Any or all of these faults can cause fibrous material to adhere to the surface. Even if the surface is free of burrs and other irregularities and is therefore substantially smooth, it can tend to attract textile material due to suction forces being set up as a result of rapid rotation of the component.
  • the present invention seeks to overcome these disadvantages.
  • a pinned component having a metallic body portion from a surface of which textile pins project, and wherein the pinned surface is of a smooth but textured nature.
  • a smooth but textured surface we mean, for example, one which is similar in nature to the skin of an orange.
  • the body of the component is formed of aluminium, or an aluminium alloy, and the pins are made of steel.
  • the pins may form a force fit in apertures in the body but preferably, they are secured in the body in the manner described in our U.K. Patent Specification No. 1298561.
  • this operation is carried out after the surface has been pinned, thereby ensuring that burrs and/or excess adhesive used for securing the pins in place is/are removed from the surface and around the base of the pins.
  • spherical glass beads having a diameter of between 45 and 85 microns are used for the shot blasting process. It had been found that these do not affect the surface of the pins, and can in fact smooth the surface of the pins, whereas the softer material of the body is texturised.
  • the textured surface is provided by a chemical etching process, using any one of the number of commercially available chemical etchants. If the pins are formed of stainless steel, then the pinned component can be etched subsequent to pinning, otherwise the process would be performed prior to pinning.
  • the pinned component would normally be mechanically or chemically treated after the fixing of the pins in position, it is believed that improved results can be obtained if just the drilled surface of the body of the components from which the pins will project is treated, prior to insertion of the pins.
  • textured pinned components are expecially suited to textile processing, treating or finishing, it will be appreciated that the components can be used for other purposes.
  • pinned components have a textured surface on the body from which the pins project can be used for fibrillating and other slitting or shredding operations, e.g. in the tabacco industry.
