IN YARN PRODUCTION, APRON CLADDING MECHANISM AND METHOD TO THE ROLLERS COATED WITH ELASTIC MATERIAL AND FOUND IN THE DRAFTING AND GUIDING ZONE, HAVING SHIFT STRUCTURE AND PRE-TENSIONING MECHANISM

摘要

The purpose of the invention is to reduce the abrasive impact of the fibre or the yarn on the rollers coated with elastic material, which are used for drafting and guiding purposes in yarn production techniques, and thus keep the operating conditions and yarn quality parameters constant. The fibre on the top rollers coated with elastic material especially in the mechanical ring compact yarn production among the yarn production techniques, is an apron cladding method, over the top roller and the bearing guide arms connected to a bearing body found on the bearing unit placed on the pressure arm, in a way that it would cover these together. The method includes the operation steps of stretching the aprons by application of tension via a tension component and, while the fibre drafting operation continues, the bearing unit carrying the aprons being shifted in the horizontal plane in certain intervals.
