Abstract
A sprayer of an elongated shape receives a desired liquid from an outside urce and spray-applies the liquid onto a fiber in response to motivating force provided by pressurized gas. The unsprayed, virgin fiber enters the sprayer through an inlet hole, is sprayed on with the liquid as it travels the width of the sprayer and exits the sprayer as a sprayed fiber through an exit hole. The pressure of the motivating gas can be varied to provide the optimum jettisoning force for a selected liquid, taking into consideration the viscosity, volatility and other pertinent characteristics of the liquid.
