ABSTRACT:
A device for applying a coating to moving fibers is shown comprised of a cylindrical applicator rotating about its axis, a support frame for supporting the cylindrical applicator wherein said support frame contains a cylindrical opening running through the support frame for supporting the cylindrical applicator, a slot with an opening running from the slot to the cylindrical opening, an internal passageway in the support frame and a tubular connecting piece which fits partially in the internal passageway of the support frame for delivering the coating to the surface of the cylindrical applicator. It is critical that the diameter of the cylindrical applicator be only slightly less than the diameter of the cylindrical opening running through the support frame, thus restricting the amount of liquid coating that can be applied to the moving fiber. By placing the tubular connecting piece directly adjacent to the cylindrical applicator, no pool of coating is created. Thus, the amount of the fluid that is applied to the cylindrical applicator can be strictly controlled.
