Problems solved by technology

[0016] In this case, the production of these elements made of plastic material and steel is problematic, since the plastic material injected at high pressure either severely deforms the inner parts made of steel or presses them strongly against the on the support core, making it virtually impossible to remove the support core without damaging the inner surface of the tube insert
Therefore, for open-end open-end spinning devices, especially for fiber guide tubes, the above-mentioned elements or known manufacturing methods have not been successful in practice

Embodiment Construction

[0037] It is known that the open-end spinning device 1 shown in FIG. 1 has a rotor housing 2 in which a spinning rotor 3 rotates at high speed. In this case, the spinning rotor 3 is supported by its rotor shaft in the interspace of the support disc support 5 and is loaded along the length of the machine by a tangential belt 6 regulated by pressure rollers 7 . The rotor housing 2 , which is itself open towards the front, is closed during operation by a pivotally mounted cover 8 having a tube plate comprising a seal 9 . The rotor housing 2 is also connected via a corresponding suction pipe 10 to a vacuum source 11 which generates the necessary spinning vacuum in the rotor housing 2 .

[0038] A preferably replaceable tube plate extension, a so-called tube plate adapter 12 , is arranged in a receiving opening of the tube plate 37 , which is not shown in greater detail. The tube sheet adapter 12 has a threaded extraction nozzle 13 and a mouth region of a fiber guide tube 14 accor...

Abstract

The invention relates to a fiber-guiding duct for an open-ended spinning device in order to pneumatically connect a sliver-dissolving device in an uninterrupted manner to a spinning rotor that revolves in a vacuum-impinged rotor housing at a great rotational speed. Said fiber-guiding duct is composed of at least one wear-resistant, tubular duct insert. According to the invention, an oversized duct insert (18A or 18B) is cast into an injection-molded or diecast component (12, 43), said duct insert (18A or 18B) obtaining its final dimensions only during the casting process by pressing the duct insert (18A or 18B) against at least one associated interior supporting slide.

Description

technical field [0001] The invention relates to a fiber guide tube for an open-end spinning device having the features of the preamble of claim 1 and to a method for producing a fiber guide tube of this type (claim 2 ). Background technique [0002] Fiber guide tubes are already known in various embodiments together with open-end spinning machines, for example open-end spinning machines, and are described in detail in numerous documents. In this case, single-part fiber guide pipes are known, as well as two-part fiber guide pipes, for example consisting of a fiber guide pipe inlet element fixed in the connection hole of the opening roller housing and bonded to the tube sheet ( duct plate) fiber guide tube outlet element in the adapter. [0003] Two-part fiber guide tubes of this type are described, for example, in DE 197 12 881 A1 or DE 195 11 084 A1. [0004] In this case, the design of the fiber guide tube via which the individual fibers are conveyed from the opening roll...
