METHOD AND DEVICE FOR SIMULTANEOUSLY LAUNCHING MULTIPLE CONTINUOUSLY CONTINUOUS TEXTILE YARNS

摘要

THE INVENTION CONCERNS A METHOD AND A DEVICE FOR SIMULTANEOUSLY LAUNCHING MULTIPLE CONTINUOUSLY CONTINUOUS TEXTILE YARNS IN ORDER TO RENOVATE THEM IN SEPARATE WINDINGS ON THE SAME PIN OF A BOBINOIR: / P P - IN A FIRST PHASE, THREATS ARE ARRANGED ACCORDING TO SEPARATE PATHS DEFINED BY SEPARATE TRIANGULATION GUIDES SITUATED AHEAD OF THE SPINDLE AND A COMMON CONVERGENCE POINT LOCATED DOWNSTREAM; - IN A SECOND PHASE, KEEPED OUT OF THE SCOPE OF THE VA-AND- SYSTEM COMING TOGETHER, THEY ARE SEIZED SELECTIVELY BY A SELECTION DEVICE CONSISTING ESSENTIALLY OF A MOBILE-CONTINUOUS ELONGATED ELEMENT, OF THE BELT TYPE, PROVIDED WITH SELECTION GUIDES OF DIFFERENT LENGTHS GROWING REGULARLY SPACED ALONG THE BELT AND PROVIDED EACH FACING ITS WINDING ZONE. THE PIN; - IN A THIRD PHASE, THEY ARE MOVED UNTIL A MEANS OF HANGING ON THEIR SUPPORT, TO START THE WINDINGS. / P P APPLIES TO THE LAUNCHING OF THREADS, IN PARTICULAR IN ONE PROcessu S COMPLETELY AUTOMATIC CAVAGE. / P
