Problems solved by technology

Formation of two stiffer terminal projections, giving the bobbin an M-shaped profile; this uneven winding creates significant disadvantages for the use and further processing of the spun yarn wound on said uneven bobbin
[0031] This winding effect is not permissible for certain uses of the spun yarn; therefore in some cases it is necessary to unwind the bobbins produced in the open-end spinning machine and additional operating time is required and cost for more uniform rewinding

Embodiment Construction

[0040] Figs. 2A and 2B show the yarn guide bar 22, which has a pitch corresponding to the pitch of the spinning unit 2 in Figs. 1A and 1B from the yarn guide 21. The moving equipment assembly of the yarn guide device is formed in such a way that the structure and materials are directly selected with the greatest savings in weight to ensure high rigidity and movement accuracy with the lowest possible weight. For example, the rod and the yarn guide are made of composite materials and Ceramic material. Therefore, the accuracy of the movement and the slender length of the structure require that the guides 40 are arranged along the front of the machine, for example, one for every two spinning units, and only one of them is shown in the drawing to simplify the drawing. These guides 40 are provided with a low-friction and wear-resistant surface or surface layer in contact with the guide rod 22. The yarn guide bar 22 is alternately moved so that the yarn guide 21 is translated in front of...

Abstract

A yarn guide device for collecting spun yarns on a bobbin, in particular for open-end spinning machines, which consists of a common yarn guide rod carrying a plurality of yarn guide elements for the spinning sections, said yarn guide The rod carries out an alternating movement in front of the bobbin, which is formed by the alternating forward and backward movement of a linear motor driven by the control unit of the spinning machine, wherein the alternating movement of the linear motor is consistent with The instantaneous speed and deflection amplitude of the stroke end of the yarn guide rod are related to the axial coordinate.

Description

Technical field [0001] The invention relates to collecting spun yarn produced or processed by a loom to be wound on a bobbin. Background technique [0002] In the industrial production of spun yarns, these spun yarns are usually collected on an idling bobbin carried by a bobbin carrying arm, which rests on a rotating drive roller and collects the spun yarn from the conveying element to wind it on On itself. The bobbin is thus formed by pulling and winding the spun yarn on its surface, so that it is pulled to rotate by the lower drum on which the bobbin is being formed. This method enables the spun yarn to be wound at a substantially constant linear speed, regardless of the increasing size of the bobbin, and only depending on the rotation speed of the drive drum. Since the cluster winding unit is provided with a yarn guide device that distributes the spun yarn on the outer surface of the bobbin through forward and backward axial movement, the spun yarn is spirally wound onto the r...
