Problems solved by technology

[0011] The component material should also be non-deformable for a long time, since otherwise there would be the risk of "running out" of the engagement holes with the engagement pins, which could result in a Changes in position between, which will have very adverse consequences for the associated fiber sliver opening device

Embodiment Construction

[0027] figure 1 A side view of an air spinning machine is shown in a side view, which is denoted overall by the reference numeral 1 , and which has a fiber sliver opening device 36 whose opening rollers are manufactured in accordance with the aluminum die-casting method The housing 17 is attached to the pivot cover 8 made of plastic with a precise fit.

[0028] As shown in the figure, such an air spinning device 1 each has a rotor body 2 in which a spinning rotor 3 rotates at high speed. In this embodiment the spinning rotor 3 is supported with its rotor shank 4 in a wedge-shaped member supporting the disk seat 5 and driven by a tangential belt 6 along the length of the machine and under force from a pinch roller 7 .

[0029] The rotor cup body 2, which is open to the front, is closed during the spinning operation by a rotatably mounted cover part, the so-called rotary cover 8, wherein the rotary cover 8 is machined or screwed in (not shown in detail). ) with a sealed channe...

Abstract

The invention relates to a sliver opening device for an open-end spinning device, which comprises an open-end roll housing. The open-end roll housing can be accurately positioned on a rotary cover of the open-end spinning device through a cooperating mechanism. An open-end roll is rapidly rotating in the open-end roll housing during a spinning process. The open-end roll is supported in a carrier of the rotary cover in a rotatable way through a bearing assembly. The open-end roll housing (17) has a shaft ring (410 projecting backwards in a zone of a central supporting through hole (34). The shaft ring is corresponding to a receiving hole (42) in the rotary cover made of plastic materials when the sliver opening device (36) is in an installation state. Therefore, a first cooperating mechanism (39) used for making the open-end roll housing (17) accurately positioned on the rotary cover (8) is provided.

Description

technical field [0001] The invention relates to a fiber sliver opening device for an air spinning machine. Background technique [0002] Fiber sliver opening devices for open-end spinning systems, in particular in connection with rotor spinning machines, have been known for a long time, some of which are well documented in numerous documents. [0003] These known fiber sliver opening devices which have been proven in various ways in practice have a rotatably mounted opening roller which rotates at high speed in the opening roller housing during spinning and Simultaneously, the incoming fiber sliver is carded into individual fibers, which are then fed to so-called spinning rotors. [0004] The opening roller is mounted in the bracket of the rotatably mounted cover part of the fiber sliver opening device via a bearing drive shaft, wherein the bearing drive shaft is mounted in a roller bearing arrangement and has a pulley on the end side. On the side opposite the pulley, the ...
