Embodiment Construction

[0016] On an air spinning machine, the device according to the invention comprises a housing 1 as an essential component, in which an opening roller 2 rotates in the direction of rotation A in a known manner. The circumference of the opening roller 2 is equipped with a toothed or needle clothing and is surrounded by the peripheral wall 4 of the casing 1 . The fiber material 5 fed as a sliver in the feeding direction B enters the housing 1 at a sliver feeding point 6 in which the fiber material 5 is carded into individual fibers 7 . The individual fibers 7 are discharged from the housing 1 at a fiber feed point 8 via a fiber feed channel 9 in the discharge direction C into a spinning rotor (not shown). Both the spinning rotor and the fiber output point 8 are connected to a negative pressure source not shown in the figure.

[0017] The fiber material 5 first passes through an input bell mouth not shown in the input direction B to reach a feed roller 10 rotating in the direction...

Abstract

A device on an air spinning machine consists of an opening roller revolving in a housing. In a circumferential wall of the housing surrounding the opening roller, between a sliver input point and a fiber output point, a trash removal opening is provided, which is opened to the outside atmosphere. Along the conveying direction behind the impurity removal port, an air supply port communicating with the outside atmosphere is also arranged before the position of the fiber output point. The air supply opening forms the inlet of an air supply channel, the cross section of which is infinitely adjustable by means of a rotary valve between a closed position and a maximum open position. The rotary valve has a through-channel which, at least in the most open position, forms a substantially non-deflecting part of the supply air channel.

Description

technical field [0001] The invention relates to a device on an air spinning machine having an opening roller revolving in a housing within a peripheral wall surrounding the opening roller at a fiber sliver input point and a There are at least two orifices connected to the outside atmosphere between the fiber output points connected to a negative pressure source, of which the first orifice in the fiber conveying direction is an impurity removal port that allows air supply, and the second is in the fiber conveying direction The orifice is a simple air supply opening which forms the inlet of a supply air channel whose cross-section can be infinitely adjusted between a closed position and a maximum open position by means of a rotary valve. Background technique [0002] DE 196 18 414 A1 represents the prior art for such devices. By means of the air supply port at the above-mentioned position of the known device, the air volume is effectively reduced, and thus the air flow veloci...
