pneumatic

Most of the ring spinning machines are stretched Equipped with spring-loaded double upper pins. To that To be able to load and relieve the output malt pair centrally, is in a known construction (DE-DS 33 15 305) In addition, a pneumatic load for this most heavily loaded pair of rollers vargRsehen. From a machine-long Compressed air lines are to the individual 8 load elements on the support and loading arms compressed air hoses guided.

The compressed air hoses are unprofessional endangered in the drafting system, although they are laid in contact with the support and loading arms. Leaks can also at the connection points of the compressed air hoses the machine-length compressed air line or to the loading elements or in the loading elements themselves appear.

A leak means one irregularity in the spinning process in the case of two spinning positions, since the pair of output rollers is used for the intended stretching of the material passing through required contact pressure is missing. In addition, the leakage naturally results in a permanent loss of compressed air Folrie. It is therefore important to quickly ascertain the existence of a leak in the pneumatic system of a ring spinning machine recognize.

This is achieved by means of the dea Protection claim specified features. The pneumatic load on the output delivery rollers is a static condition. In the operating state there is therefore normally no air flow. In the event of a leak on one

At the points described, a shallow air flow is created in the central compressed air line of the ring spinning machine, which is passed through a valve body at the inlet of the compressed air line in the ring spinning machine. the

Schuiache air flow is sufficient to lift a valve body lying in the valve body, whereby it in a Visible cap for the operating personnel. Ulenn after the leakage has been eliminated, there is no longer any air flow, the slide sinks down due to gravity

the valve body back.

In the drawing is a Leckacjii display, which is inserted into the central compressed air line of the ring spinning machine tiiird, shown in the sectional view. A valve body 1 uelet for the already mentioned compressed air line connection bores 2 and 3 which open into a storage space 4. A Dappelnipel 5 is screwed into this storage space, onto which a sight cap G is put on with the aid of a union nut 7. The Dappelnipel 5 encloses one in the valve

2Q valve body 1 inserted slide body B, which is raised into the position shown in the presence of an air flow üjird. The arrows mark the direction of air flow.
