Problems solved by technology

This open-end rotor spinning device in cooperation with a composite magnetic gas bearing is characterized by very low frictional losses due to its plane-parallel bearing surfaces and the rotation without radial forces of the spinning rotor mounted on it , but they are extremely complex and thus expensive to manufacture
In practice, such open-end rotor spinning devices have not yet proven themselves

Embodiment Construction

[0081] figure 1 A side view showing half of the open-end rotor spinning machine 1, in particular a station equipped with an open-end rotor spinning device. Such an open-end rotor spinning machine 1, as is known from the prior art, has a large number of such identical stations 2, which are arranged side by side in a row.

[0082] In particular, such a station 2 is equipped with an open-end rotor spinning device 3 and a winding unit 4 . This means that, during operation, the fiber sliver 6 prepared by the fiber sliver opening unit 30 and fed, for example, to the spinning drum 5, is spun into the yarn 7 in the open-end rotor spinning device 3, which is It is then wound into a cross-wound bobbin 8 on the winding unit 4 .

[0083] like figure 1 As shown, the winding unit 4 is equipped for this with a creel 9 for rotatably holding an empty bobbin or cross-wound bobbin 8, a bobbin drive roller 11 for driving the cross-wound bobbin 8 by frictional contact and a yarn traverse unit ...

Abstract

The invention relates to an open-end rotor spinning device (3) with a spinning rotor (19) which can be driven by a separate electric drive (21) and whose rotor body (17) is The rotor housing (10) circulates inside, and the rotor housing is closed by a cover (22) during the spinning process and communicated with a negative pressure source (23) via an air pressure line (29). According to the invention, at least one pneumatic line (29) arranged between the rotor housing (10) and the negative pressure source (23) is located in the separate electric drive (21) of the spinning rotor (19). ) region, whereby the spinning vacuum caused by the vacuum source (23) produces cooling of the individual drive (21) of the spinning rotor (19) through the suction air flow in the pneumatic line (29).

Description

technical field [0001] The invention relates to a free-end rotor spinning device, which has a spinning rotor that can be driven by a separate motor, the rotor body of which circulates in a rotor housing, and the rotor housing is closed by a cover during spinning and Connected to a negative pressure source via a pneumatic line. Background technique [0002] As is known from the prior art, during operation of an open-end rotor spinning machine, a certain negative air pressure is required in the open-end rotor spinning device in order to be able to perform a correct spinning job, which is called in professional circles Negative pressure for spinning. This means that in open-end rotor spinning devices a so-called spinning underpressure must be provided in the region of the rotor housing in order to be able to supply the individual fibers, respectively carded out of the feed fibers by so-called opening rollers, with the air flow and via the guide The fiber channel is fed into t...
