A system for connecting successive bobbins, in which the yarns of the different bobbins on the creel are connected to each other and are thus presented as one long yarn to the subsequent process. The system includes a plurality of devices for transporting and positioning a bobbin with yarn for provision in a creel. The system also includes a creel system that further includes a plurality of receiving positions, each of the receiving positions adapted to receive one of the devices. The devices are provided with one or more engaging elements, and the receiving positions are provided with one or more engaging mechanisms for connecting to the engaging elements.

Creel system

An improved system for fabricating alternating S/Z cabled yarn, for alternating S/Z twisted yarn and for (whether or not alternately) applying a torsion to a yarn, in which critical air flow conditions are obtained at least at the outlet of the torsion chamber of the devices. A method for fabricating alternating S/Z cabled yarn, for alternating S/Z twisted yarn and for (whether or not alternately) applying a torsion to a yarn under critical air flow conditions at least at the outlet of the torsion chamber used in the method, and a product according to these methods.

Jet and method

The current invention concerns an improved system and method for the manufacturing of alternating S/Z cabled yarn) or connected alternating S/Z twist plied yarns, in which tension decrease or increase is avoided by variable longitudinal contraction when twist plying or overtwisting yarns. This longitudinal contraction Is very difficult to predict and leads to tension in the yarns, which can affect the quality. This tension can also be reproduced in the installations. This invention tries to improve this by providing a tension compensator () that (partially) compensates the tensions and forces between different, subsequent forces for processing yarns.
