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 rather is disposed in side by side adjacent relationship to the core with the binder being twisted about the core and effect thread.

Loop chenille type yarn

A core yarn has a plurality of wrapper yarns wrapped under tension in both the clockwise and counterclockwise directions. The core is composed of staple fibers having substantially no twist so that the core has substantially zero tensile strength. The tensions on the wrapper yarns are balanced by each other and are so high as to compress the core and impart to the core a sinuous configuration along its length.

Helically wrapped yarn

Apparatus and method for making loop chenille type yarn

While being fed into a laterally confining region to be retained temporarily and be compressively crimped therein, laterally spaced textile strands are traversed laterally to and fro along the entrance to the region. The resulting uneven cross-sectional distribution of crimped strand accumulation in the region is conductive to separation of individual strands upon exiting from the region.
