Abstract
Apparatus and method for making loop chenille type yarns and yarns produced thereby are disclosed. An elongated spindle having a tapered needle surface at one end thereof is provided. The spindle has a passage therein in communication with the needle surface for feeding a core thread to the needle surface. Effect thread is overfed to the needle location where a nose piece member cooperating with the needle aids in wrapping the effect thread about the needle to form loops. The binder yarn is fed to the needle and twisted about the core and effect threads. In a preferred embodiment, means are provided for reciprocating the nose piece relative to the needle between effect thread loop forming and effect thread non-loop forming dispositions. In this manner, "thick" and "thin" novelty yarns are provided in which the thick sections of the yarn comprise looped effect threads whereas the loops are not provided in the thin yarn sections. Means may also be provided for twisting the effect thread about the binder and core threads. Further, by utilization of a novel lateral feed of the effect thread with respect to the needle surface, the effect thread is not twisted about the core thread, but …
