Device for keeping clean the regions os textile machines in contact with feed threads particularly for hosiery knitting machines or the like

Abstract

A device for keeping clean the regions of textile machines that are in contact with feed threads, particularly for hosiery knitting machines or the like, comprising a housing that delimits a space around a region where the thread makes contact with a supporting and / or guiding and / or braking element arranged along the path followed by the thread from the spool to a thread guide of the machine, where dust is generated and / or accumulates, and an aspirator device which is connected to such space.

Description

[0001] The present invention relates to a device for keeping clean the regions of textile machines in contact with feed threads, particularly for hosiery knitting machines or the like. BACKGROUND OF THE INVENTION [0002] As is known, in hosiery knitting machines the friction of the threads against the supporting and / or guiding and / or braking elements arranged along the path of the threads from the corresponding spool to the thread guides that feed them to the needles of the machine generates dust, which can harm the components of the machine. [0003] Furthermore, accumulation of dust at the various passages through which the threads pass constitutes a considerable problem since, by partially blocking such passages, it can produce an abnormal braking of the threads, even downstream of the elements designed to control and adjust the tension of the threads, with unwanted modifications of the article produced with such threads. In other cases, the thread may even break, stopping the machi...

AI Technical Summary

Benefits of technology

[0008] The aim of the present invention is to solve the problems described above by providing a device that keeps clean the regions of textile machines that are in contact with feed threads, particularly for hosiery knitting machines or the like, avoiding the scattering into the surrounding environment of the dust generated by the friction of the threads against the elements that guide, support and brake them.

[0009] Within this aim, an object of the invention is to provide a device that effectively avoids pollution of the working environment on the part of the dust generated by the friction of the threads against the elements that guide, support and brake them along their path from the spool to the various thread guides of the machine.

[0010] Another object of the invention is to provide a device that is structurally simple and can be installed on current textile machines, particularly on hosiery knitting machines or the like.

Problems solved by technology

As is known, in hosiery knitting machines the friction of the threads against the supporting and / or guiding and / or braking elements arranged along the path of the threads from the corresponding spool to the thread guides that feed them to the needles of the machine generates dust, which can harm the components of the machine.

Furthermore, accumulation of dust at the various passages through which the threads pass constitutes a considerable problem since, by partially blocking such passages, it can produce an abnormal braking of the threads, even downstream of the elements designed to control and adjust the tension of the threads, with unwanted modifications of the article produced with such threads.

In other cases, the thread may even break, stopping the machine and causing production losses.

However, this solution has the problem that it scatters the dust in the vicinity of the machine, causing problems as regards the healthfulness of the working environment and because the removed dust tends to settle on other parts of the machine.

Furthermore, the air jets, which for reasons related to savings on compressed air cannot be continuous but can only be intermittent, do not ensure the gradual elimination of accumulations of dust, which is no longer removed when it agglomerates into large masses.

Sometimes the air jets can also interfere with the regular advancement of the threads.
