Abstract
A coating material applicator is provided which applies a coating material to fibers, more specifically filaments, in a uniform manner. The applicator, which has no moving parts, directs the coating material in a tortuous path from a supply inlet to a filament-coating bar which applies the coating material to the filaments passing thereby. The tortuous path preferably has at least one inverted U-shaped portion which helps separate air trapped in the coating material. The applicator preferably has at least three chambers with the coating material passing down through the first chamber, up through the second, and down through the third from which it exits to the coating bar. Fibrous material can be located in the first chamber, and also in the second, if desired, to help separate and collect the air from the coating material. A vent also can be located in the first chamber and in the second, too, particularly if that chamber also has fibrous material therein, to vent the air periodically.
