- 17 - INTERMITTENT COATING APPARATUS AND METHOD ABSTRACT OF THE DISCLOSURE Coating apparatus comprises a coating head (12) for positioning over a substrate (18) to be coated. The coating head (12) includes a reservoir (20) for holding an amount of slurry (22) to be applied to the substrate (18). The reservoir (20) is provided with a slurry discharge opening (38) for discharging slurry onto the substrate (18). A closure member (24) is provided for selectively opening and closing the slurry discharge opening (38). The apparatus further includes means for intermittently raising and lowering the coating head (12) relative to the substrate (18) in synchronism with the opening and closing of the slurry discharge opening (38). In a particular embodiment, the raising and lowering means comprises a cam-driven rocking frame (14) on which the coating head (12) is mounted. A coating method in which the coating head (12) is raised upon closing of the slurry discharge opening (38) is also provided.
