ABSTRACT:
A metering apparatus 10 for continuously supplying a specified amount of fluid material F to a desired surface. The apparatus 10 includes a reservoir 14 for maintaining a supply of fluid material, a housing 16 having a central bore 22 therethrough, a receiving opening 24 for receiving fluid material from the reservoir 14 to central bore 22, and an exit opening 26 through which fluid material exits the housing 16. A rotatable screw member 28 is provided engaged through the housing 16 within said central bore 22, and a driver 37 engaged with the screw member for rotating the screw member within the bore at between approximately 1 rpm to 2,700 rpm, and preferably approximately 1,750 rpm, in order to continuously supply fluid to the exit opening 26. At this operating level, fluid material is provided from the exit opening 26 at a flow rate of between approximately 1 to 23 grams/min, and in a thickness of approximately 0.001 to 8 mils. The reservoir 14 includes a tank 50 for the fluid material, and a motor 68 for agitating the fluid during operation of the apparatus 10. The housing 16 is secured adjacent the tank 50 to provide the fluid material from the tank to the receiving opening 24.
