Abstract
The present invention relates to an improved system and method for the production of heatset yarns, in particular for the production of heatset alternating S/Z cabled yarns. The invention also relates to the product obtained according to the method, namely an improved heatset twist plied yarn.
Claims17
A system for manufacturing heatset twist plied yarns, comprising:
- at least one twist plying device configured to twist plying at least two incoming yarns;
- at least one accumulation device configured to receive, accumulate and forward the twist plied yarns from the at least one twist plying device, the accumulation system configured to temporary accumulate the twist plied yarns;
- and
- at least one heatsetting device configured to receive and heatset the twist plied yarns of the at least one accumulation device to manufacture at least one heatset twist plied yarn;
- wherein at least one twist plying device is configured to operate uninterruptedly, the heatsetting device configured to operate intermittently and periods of operation of the heatsetting device being alternated with periods of stopping the heatsetting device, and whereby the accumulation device is configured to temporarily retain the accumulated twist plied yarns when stopping the heatsetting device.
2 more elements
A method for manufacturing the heatset twist plied yarns, comprising:
- twist plying one or more groups of two or more yarns to produce one or more twist plied yarns;
- receiving the one or more twist plied yarns by at least one accumulation device;
- accumulating the one or more received twist plied yarns by the at least one accumulation device wherein the accumulation device is configured to temporary accumulate of the twist plied yarns;
- passing the accumulated twist plied yarns from the at least one accumulation device to at least one heatsetting device;
- heatsetting the twist plied yarns in the at least one heatsetting device for the manufacture of at least one heatset twist plied yarn;
- wherein the step of twisting takes place continuously, while heatsetting occurs intermittently and periods of heatsetting are alternated with periods of stopping of the heatsetting, and wherein passing the accumulated twist plied yarns to the at least one heatsetting device is temporarily stopped when the heatsetting device is stopped.
3 more elements
Accumulation device for receiving, accumulating and transmitting incoming, preferably twist plied, yarns, comprising:
- a spool configured to receive yarns wound around it;
- a yarn supply through which the incoming yarns are guided;
- a yarn guide, which is connected to the yarn supply, which guides the yarns supplied by the yarn supply further to the spool, the yarn guide configured to rotate relative to the spool about the longitudinal axis of the spool;
- a yarn exit for exiting the yarn wound around the spool;
- a propagation system configured to move the yarn wound around the spool along the longitudinal axis of the spool in the direction of the yarn exit;
- and
- one or more detection systems configured to determine a degree of filling of the spool with the yarns wound around it.
