Problems solved by technology

However, the disadvantage of such opening roller shells is that their production costs are relatively high, especially the electroless nickel plating of the opening roller shells makes it feel disadvantageous in terms of production costs

Embodiment Construction

[0021] figure 1 An open-end spinning device, generally designated by the reference numeral 1 , is shown in side view, on which an opening roller housing 17 produced by the method according to the invention is used.

[0022] As shown in the figure, such an open-end spinning device 1 has a rotor housing 2 in which a spinning cup 3 rotates at high speed. In this case, the spinning cup 3 is supported with its rotor shaft 4 in the wedge support of the bearing disc seat 5 and is acted upon by a tangential drive belt 6 in the longitudinal direction of the machine, which is adjusted by a pressure roller 7 .

[0023] The rotor cup housing 2 , which is open to the front, is closed during operation by a rotatably mounted cover 8 , in which a channel plate (not shown in detail) with a seal 9 is machined. The rotor housing 2 is also connected via a corresponding vacuum line 10 to a vacuum source 11 which generates the spinning pressure (spinnunterdruck) required in the rotor housing 2 dur...

Abstract

The method involves using a light metallic material for manufacturing the opening roller housing (17), where the opening roller housing has a circular opening roller receiver (31). Openings are arranged in the circumferential wall of the opening roller receiver. The opening roller housing is so impinged with a sand blast medium in a finishing process that the surfaces (33,35) of the opening roller receiver (31) is micro compressed and supports a roughness which ensures that no adhesion forces occur in area of the surfaces (33,35) during the operation of the opening roller housing (17), thereby ensuring ordered conveying of the opened single fiber in the opening roller receiver (31).

Description

technical field [0001] The invention relates to a method for producing an opening roller housing of an open-end spinning device having the features of the preamble of claim 1 and to an opening roller housing produced according to this method. Background technique [0002] Opening roller housings for open-end spinning devices have long been known and are clearly documented in numerous patent applications. [0003] DE 197 09 213 A1 discloses, for example, a fiber sliver opening mechanism for an open-end spinning device with a mainly rectangular opening roller housing made of light metal material and having a circular opening roller cavity. Furthermore, the opening roller housing has a front wall and a rear wall which form special ventilation guide surfaces. In addition, two openings are machined in the peripheral wall of the opening roller chamber, the larger first opening is used to feed the fiber sliver and separate out the foreign particles, and the spinning air required f...
