Sheet coating apparatus

A sheet coating apparatus for coating a coating liquid on both a top surface and a bottom surface of a sheet traveling along a predetermined transfer path, comprising:

• first and second storage tanks in which the coating liquid is contained;
• first and second coating rollers, which are in contact with the sheet and which are rotatably installed on the transfer path, for coating the coating liquid supplied from the first and second storage tanks respectively on the top and bottom surfaces of the sheet;
• and
• first and second coated amount regulating mechanisms securely pressed against surfaces of the first and second coating rollers, respectively, for regulating the amount of the coating liquid coated on the sheet by squeegeeing the coating liquid adhering to the surfaces of the first and second coating rollers,
• wherein the first storage tank, the first coating roller and the first coated amount regulating mechanism are installed above the transfer path and the second storage tank, the second coating roller and the second coated amount regulating mechanism are installed below the transfer path to simultaneously coat both the top and bottom surfaces of the sheet.
