High-capacity bobbin with a built-in ball control head and folding system

Abstract

High capacity spool with built-in balloon control head (1) and folding system consisting of a spool composed of a balloon control head (1), a central tube (2) and a base (3) and of a folding system adjusted to this spool in two stages, a first stage in which a support cone for the second stage is obtained. The result obtained on the spool is a format whose final appearance is that of the so-called bottle type, although this fold differs from the habitual bottle fold, appropriate for any kind of material. The high capacity spool with built in balloon control head (1) and folding system are of use in preventing the material to be spun or twisted from wearing down against any surface because of the balloon effect. The high capacity spool with built-in balloon control head (1) and folding system is applicable on continuous ring spinning frames, ring twisting frames and twister-lap formers.

Description

OBJECT OF THE INVENTION[0001] The object of the present invention is related to a high capacity bobbin or spool with built-in ball or balloon control head and to a folding system for said spool, both having application in continuous ring spinning frames, ring twisting frames and ring twister-lap formers.[0002] At present, continuous ring spinning frames, ring twisting frames and ring twister-lap formers are limited in their capacity to twist or spin at high speeds due to the balloon effect. This effect causes the thread to wear down by friction against one or several surfaces called balloon control ring, making the thread fray and thus creating the necessity to increase the size of the traveller and lower production speed to eliminate the wearing or deterioration of the fibres that make up said thread or yarn.[0003] The high capacity spool with built-in balloon control head and folding system for said spool has been developed in order to eliminate the inconveniences of continuous sp...

AI Technical Summary

Benefits of technology

[0002] At present, continuous ring spinning frames, ring twisting frames and ring twister-lap formers are limited in their capacity to twist or spin at high speeds due to the balloon effect. This effect causes the thread to wear down by friction against one or several surfaces called balloon control ring, making the thread fray and thus creating the necessity to increase the size of the traveller and lower production speed to eliminate the wearing or deterioration of the fibres that make up said thread or yarn.

[0010] In the second stage of the folding process, the spooling is carried out with a constant vertical movement or spooling distance C. When the lever is raised, movement distance C is increased with advance A distance, so that a vertical ascending movement distance of C+A is obtained. In vertical descending movement, the distance covered is C, so that the so-called bottle type appearance is achieved as a final effect of the sum of the two stages of folding, although the folding itself differs from the usual bottle fold, appropriate for any type of material since the control rings can be omitted as the thread follows the central tube of the spool so the main focus of friction is eliminated. This application also facilitates the elaboration of any type of thread with a traveller that has a lower mass in comparison to the ring balloon control system, which facilitates an increase in the production speed of the machine the spinning or twisting process is carried out on.

Problems solved by technology

At present, continuous ring spinning frames, ring twisting frames and ring twister-lap formers are limited in their capacity to twist or spin at high speeds due to the balloon effect.

This effect causes the thread to wear down by friction against one or several surfaces called balloon control ring, making the thread fray and thus creating the necessity to increase the size of the traveller and lower production speed to eliminate the wearing or deterioration of the fibres that make up said thread or yarn.
