APPAREIL ET METHODE POUR PRODUCTION DE FILS FANTAISIES TEL LE FIL-CHENILLE

摘要

A device for the production of fancy or fluffy yarns, such as chenille, has a frame along the length of which a plurality of individual forming units are spacedly mounted, each unit including a spindle and forming arrangement for delivering warp threads bound by encircling weft threads to a roller arrangement which also receives binder threads from a creel on the frame and which has an associated rotary knife that severs the weft threads with the warp and binder threads, having the cut weft threads thereon, being taken up on a pair of takeup spindles of a ring-spinning frame. A main drive means is provided for each unit and is drivingly connected through separate transmission means with the spindle and forming arrangement, the associated roller arrangement and the associated pair of takeup spindles with each drive transmission means being adjustable for coordinated operation of such components. A separate drive means is provided for each knife which is adjustable relative to its associated roller arrangement. The twisted threads are conveyed from the spindle and forming arrangement to the roller arrangement by a feed roller assembly which is driven by the drive means for the spindle arrangement. A selectively actuatable control means for the feed roller assembly controls the feeding of the threads in the method of forming loop, seed and other fancy yarns.
