Abstract
The invention relates to a rotary plate of a spinning machine, in particular a section or a carding engine, for depositing a sliver in a canister, with a base body (2) and a band channel (3) arranged in the base body (2). In accordance with the invention, it is proposed that, when the rotary plate (1) is used as intended, the side of the rotary plate turned towards the rotary plate (1) features, at least partially, a coating (6) with a spatial configuration made of spherical, irregular elevations (11).
Claims
1. Rotary plate of a spinning machine, in particular a section or a carding engine, for depositing a sliver in a canister, with a base body (2) and a band channel (3) arranged in the base body (2), characterized in that, upon the intended use of the rotary plate (1), the side of the rotary plate (1) turned towards the canister features, at least partially, a coating (6) with a spatial configuration made of spherical, irregular elevations (11).

Description
[0031] Further advantages of the invention are described in the following embodiments. The following is shown:
[0032] FIG. 1 a schematic structure of a rotary plate,
[0033] FIG. 2a a cross-section of a coating with spherical, irregular elevations,
[0034] FIG. 2b a cross-section of a coating with a smaller number of spherical, irregular elevations and
[0035] FIG. 3 a cut-out of an edge area of a rotary plate with a cover and a coating.
[0036] FIG. 1 shows a schematic structure of a rotary plate 1. Thereby, the rotary plate 1 consists of a base body 2 and a band channel 3 arranged in the base body 2. A sliver (not shown here) is guided through the band channel 3 and leaves the rotary plate 1 downwards through an opening 4 of the band channel 3 and of the base body 2. A cover 5 is fastened to the base body 2 on the underside of the rotary plate 1 and also features the opening 4. This underside is the side that is turned towards a canister when the rotary plate 1 is used as intended. A coating 6, which is described in more detail in FIG. 2, is applied to the lower surface or the underside of the cover 5.
[0037] FIG. 2a shows a cross-section of the coating 6 with spherical, irregular elevations 11. The coating 6 is applied to a substrate material 7. Thereby, the substrate material 7 can be part of the cover 5 or part of the base body 2. The coating 6 features three individual layers, namely a base layer 8, a structure layer 9 and a cover layer 10. The base layer 8 adheres to the substrate material 7, and serves, for example, as a carrier layer for the structure layer 9 or compensates for the unevenness of the substrate material 7. The structure layer 9 with the spherical, irregular elevations 11 is applied to the base layer 8. As can be seen, the elevations 11 feature different sizes. The cover layer 10 closes the coating 6 to the outside.
[0038] FIG. 2b shows a similar cross-section of the coating 6 as shown in FIG. 2a. Therefore, the same components as those in FIG. 2a are not addressed here. However, the elevations 11 are arranged less tightly on the base layer 8; that is, the number of elevations 11 per surface area is less than that in FIG. 2a. In each case, two elevations 11 can feature a spacing, which can be in the range of several orders of magnitude of an average elevation 11. If an average elevation 11 features an extension in the range of, for example, 5 μm, the spacing between two elevations 11 can amount to, for example, 50 μm. However, it is also conceivable for the spacing between two elevations 11 to feature only a fraction of the extent of an elevation 11. Thus, for example, it is also possible that the spacing between two elevations 11 amounts to only 1-2 μm or even less.
[0039] FIG. 3 shows a cut-out of an edge area of the rotary plate 1 with the cover 5. A groove 12 is arranged in an edge area of the base body 2 of the rotary plate 1. The cover 5 is attached to the base body 2 by the sides of the cover 5 being rolled into the groove 12. The coating 6, which is shown only as indicated on the basis of its small extension in comparison to the rotary plate 1, is arranged on the cover 5. However, the coating 6 does not reach the area in which the cover 5 is rolled. Thus, this is a section in which no coating 6 is arranged.
[0040] This invention is not limited to the illustrated and described embodiments. Variations within the scope of the claims, just as the combination of characteristics, are possible, even if they are illustrated and described in different embodiments.
