Abstract
Apparatus for applying liquid to a running yarn in a textile machine comprises a hollow body providing a manifold for the liquid and an elongate tube extending horizontally across the manifold. The tube is retained in a bore in the body by a yarn guide which is detachably secured to the body and the bore in the tube communicates with a groove yarn path provided by the yarn guide via a bore in the yarn guide of larger diameter than the bore in the tube. The constant supply of liquid to the yarn is provided by the controlled flow of liquid along the tube whose length is at least 100 times the diameter of the bore therein. A height adjustable weir in a liquid supply tank supplies liquid to the manifold at a predetermined pressure. The yarn path has a plurality of yarn contact points to ensure complete application of liquid by the yarn.
