Abstract: An applicator for use in applying chemical treatments to textile fibers is described which does not require the presence of a reservoir of the chemical treatment in close proximity to where the textile fibers are treated. The applicator has a rotating cylindrical roll which rotates continuously during application and is in rotatable horizontal attachment with a support means. The rotating cylindrical roll contacts the filaments at one portion one roll while at another portion on the roll a delivery means having a slot and cavity to which there is provided the chemical treatment is in fluid contact with the rotating applicator roll. The chemical treatment flows from the cavity through the slot and onto the rotating applicator roll to contact the textile filaments at another location on the roll. The chemical treatment is supplied to the cavity of the delivery means by a fluid control means which provides a continuous and controlled amount of the chemical treatment to the delivery means.

Abstract: Textile filaments are treated with chemical solutions during their manufacture and a longevous apparatus is provided to accomplish this treatment. The apparatus is a cylindrical sleeve engaged with a rotating engaging means for a substantial portion of the sleeve length and the sleeve and means are disposed to be contacted with the chemical solution contained by a receptacle. The peripheral surface of the sleeve is disposed in relation to the receptacle so that the sleeve comes in contact with the moving textile filaments. The sleeve can be a graphite, metallic or metallic coated noncorroding material. The sleeve can have a thickness ranging from a foil to a thickness which allows the sleeve to be coated with a metallic coating. The rotatable engaging means can be a noncorroding material such as stainless steel, a thermosetting polymer, graphite or rubber.

Abstract: A traversing device composed of a central shaft or axle with a wire for traversing of the strand arranged in a generally oval shape surrounding the shaft. The wire in the oval shape is supported such that the plane of the oval is traverse of the shaft at an acute angle and the wires of the oval are generally at an equal distance from the shaft at all points.
