Coating feeder system

A coating feeder system comprising, in close vicinity to an under portion of an outer peripheral surface of a gravure roll, a coating container or vessel defining a reservoir for storing a coating under a pressurized condition, a stirring and feeding roll rotatably mounted within said reservoir for stirring the coating within said reservoir a coating feed passage which permits feeding of the coating through a central axial hole and a large number of radial holes in said stirring and feeding roll into the reservoir, a pumping mechanism and a very small pressure chamber defined in the downstream from said reservoir in the rotational direction of said gravure roll and keeping the coating carried out of said reservoir under a pressurized condition for depositing the coating further axially uniformly on said gravure roll.

A coating feeder system comprising, in close vicinity to an under portion of an outer peripheral surface of a gravure roll having a small diameter of 20 to 40 mm and adapted to provide the application of a coating on a lower surface as a continuous traveling web at a place in which an upper surface of the web is free, a coating container or vessel defining a reservoir for storing under a pressurized condition, a stirring mechanism for stirring the coating within said reservoir and a very small pressure chamber defined in the downstream from said reservoir in the rotational direction of said gravure roll and keeping the coating carried out of said reservoir under a pressurized condition for depositing the coating further axially uniformly on said gravure roll.
