ABSTRACT:
An apparatus for coating a pattern of spaced discrete patches on a web of material includes an extrusion die and a metering pump which supplies coating fluid to the extrusion die from a fluid reservoir. A valve directs fluid to either the extrusion die or the fluid reservoir and a piston provides a controlled excess of flow of fluid to the extrusion die. A controller, including a digital preset counter, controls the length of the coated portions of the web, the distance between the coated portions of the web, and the timing of the valve with respect to the operation of the piston.
