Abstract
The disclosure embraces a method of and apparatus for applying a liquid material aftertreatment to texturized or bulked strand or yarn and particularly strand or yarn of glass fibers or filaments. The method and means of application of the liquid material aftertreatment to the texturized or bulked strand or yarn involves advancing the texturized strand or yarn over an applicator, applicator body or member wherein the applicator body is provided with an opening or orifice through which the liquid material is delivered onto the texturized or bulked strand or yarn and the liquid treated texturized or bulked strand or yarn wound into a package on a rotating body. One of said bodies is reciprocated with respect to the other for traversing the liquid treated texturized strand or yarn lengthwise of the package during winding of the package. Applicator bodies having different size orifices are interchangeable for treating strands or yarns of different volumes or yields in order to secure saturation of the texturized strand or yarn by the liquid material.
