Abstract:
A sheet coating apparatus for coating a coating liquid on a surface of a sheet traveling along a predetermined transfer path, comprising:a storage tank containing a pool of the coating liquid; a coating roller, which is in contact with the sheet and which is rotatably installed on the transfer path, for coating the coating liquid supplied from the storage tank on the surface of the sheet; a coated amount regulating mechanism which is pressed against a surface of the coating roller and which regulates an amount of the coating liquid coated on the sheet by squeegeeing the coating liquid sticking on the surface of the coating roller, wherein the coated amount regulating mechanism includes a compression roller; and a pressing mechanism which adjusts the squeegeeing efficiency of the coating liquid by adjusting a pressing force of the compression roller relative to the coating roller, wherein the pressing mechanism includes at least one spring for elastically biasing the compression roller in a direction in which the compression roller is pressed against the coating roller, and at least one screw for tightening or loosening the spring in a direction in which an elastic force is applied.
