Problems solved by technology

[0004] Top sheath rollers and fiber guide aprons available hitherto are exposed due to high mechanical loads and, depending on the material processed, are exposed to softeners, cotton wax, fiber residues or even dye residues from multicolored fibers objects, thus ultimately leading to high wear, short service life, highly fluctuating friction conditions, and damage to the material being processed, e.g. in the form of broken threads or entanglements

Embodiment Construction

[0033] figure 1 A top sheath roller 1 is shown in section, such as is typically used in spinning machine drafting arrangements. The upper sheathing roller has a substantially cylindrical core 5 comprising plastic. The skin layer 10 is arranged on the core 5 . In the illustrated embodiment, the skin layer 10 is arranged to cover the entire area. The structure of the entire area makes it possible to have a simple coating process. However, partial coating structures of the sheath layer are also possible, for example at locations on the upper sheathing roller which are subjected to specific mechanical loads.

[0034] figure 2 The fiber guiding apron 1' is shown in section. In the present case the section shown is elliptical, but it can also take other forms, depending on how the fiber guiding apron is guided in the drafting configuration. The fiber guiding apron 1' has a core 5 comprising plastic, on which a sheath layer 10 is arranged to cover the entire area.

Abstract

The invention relates to an upper roller cover and fiber guide belt with nanometer granules, in particular to an upper roller cover or fiber guide belt (1, 1')for a spinning device, in particular fora ring-shaped spinning machine, which has a core (5) containing plastics. A cover layer (10, 11, 12) is at least in part arranged on the core (5) and comprises one or multiple layer of nanometer oxideceramics, nanometer nitride ceramics, nanometer carbide ceramics, nanometer boride ceramics, carbon, sulphur, metal, metal alloy or their mixture. The thickness of the cover layer (10, 11, 12) is below 100 nm. The invention also discloses a method for producing the upper roller cover and fiber guide belt.

Description

technical field [0001] The invention relates to a top roller covering and a fiber guide apron, provided with a nanoparticle-containing coating or comprising a nanoparticle-containing material, and to a method for their production. Background technique [0002] The top sheath roller and the fiber guiding apron are parts of the drafting structure which in turn forms an important part of many spinning machines (for example ring spinning machines). By drafting, on the one hand, the cross-section of the sliver is reduced and, on the other hand, the fibers are oriented, parallelized and subsequently solidified. [0003] The top sheath roller and the fiber guide apron are formed in particular from plastic. Constructions made of metal are also possible for the fiber-guiding aprons. Plastics are understood to mean macromolecular organic materials, which are produced by chemical transformation of already highly molecularized natural substances such as cellulose or natural rubber, or...
