Problems solved by technology

[0033] That is to say, in order to produce the helical structure on the inlet region of the yarn navel, a relatively complex and overall particularly expensive tool is required
[0034] A further disadvantage in these yarn navels is that the helical structure flows out towards the edge of the yarn navel, which results in the yarn formation area in the groove of the rotor during spinning being different from the The distance between the helical structures of the true twist of the thread is constantly changing

Embodiment Construction

[0061] exist figure 1 The air spinning device shown schematically in , is designated as a whole by the reference number 1 . Such a spinning device has, as is known, a rotor housing 2 in which the rotor part of a rotor 3 rotates at a relatively high rotational speed.

[0062] The rotor 3 is supported with its rotor shaft 4 in the bearing wedge of a washer bearing 5 and is driven by a machine-length tangential drive belt 6 which is loaded by means of a pressure roller 7 . The axial fixation of the rotor shaft 4 takes place, for example, via a permanent-magnetic thrust bearing 18 .

[0063] The rotor housing 2 which is open towards the front can be closed during spinning by a pivotably mounted cover element 8 .

[0064] That is to say, a channel disk opens into the cover element, which channel disk bears against the rotor housing 2 with a lip seal 9 .

[0065] Furthermore, the rotor housing 2 is connected via a corresponding suction line 10 to a low pressure source 11 which ge...

Abstract

This invention relates to the yarn navel which belongs to one kind of airflow spinning device.It includes a coaxial structure which arranges in the entrance funnel, and a slot is apart from the funnel in a certain distance.The slot, which goes along the yarn's movement direction ,is located in the downstream of the coaxial structure. According to this invention,the coaxial arrangement structure (30) constitutes through the different diameter circular bulges or the slots (32).

Description

technical field [0001] The invention relates to a yarn navel for an open-end spinning device according to the preamble of claim 1 . Background technique [0002] Yarn navels for open-end spinning devices have long been known in the art and are known in various embodiments. [0003] A common problem in open-end spinning devices is that the true twist of the yarn introduced by the rotation of the spinning cup is unevenly incorporated into the yarn being formed. [0004] That is to say, the true twist of the yarn is firmly deposited on the yarn section that is then located between the yarn navel and the yarn draw-off mechanism of the rotor spinning device. [0005] In contrast to this, the true yarn twist is often introduced only particularly incompletely into the yarn section preceding the yarn navel. [0006] Since a particularly low yarn twist in the yarn section located between the rotor groove and the yarn navel has a particularly bad influence on...
