ABSTRACT:
The method is related to intermittent coating capable of distinctly defining a boundary between a coated region and an uncoated region on a web, to thereby intermittently form a coated film on the web with increased accuracy and efficiency. A coating liquid feed pump is arranged so as to alternately communicate with a circulation line and a pocket of an extrusion type coater through a directional control valve, resulting in coating liquid being intermittently fed to the pocket and then forced out of a slit, so that coated regions and uncoated regions may be alternately formed on a conductive sheet material. During interruption of communication between the pocket and the feed pump, the pocket is permitted to communicate via a discharge pipe and a shut-off valve with a sub-tank to reduce a pressure of coating liquid in the pocket, to thereby prevent undesired feeding of coating liquid to the uncoated region beyond an end position of the coated region.
