Abstract

An apparatus and method are provided for applying liquid to a yarn running at high speed, and with a relatively low resistance being imparted to the yarn during the application. The apparatus includes a roller partially immersed in a liquid bath, and having a circumferential surface composed of alternating lands and grooves in the circumferential direction. Means are provided for rotating the roller and for guiding the running yarn tangentially across the top portion of the roller, and such that the yarn advances at a linear speed substantially greater than the peripheral speed of the roller. The yarn guiding means is adjustable to permit the extent of the contact between the yarn and the top of the roller to be varied.
