摘要： In the gravure coating apparatus, while a bead portion of a coating liquid is formed between a roll surface of a gravure roll to which the coating liquid is excessively supplied and a web that runs continuously, the web is pressed on the gravure roll by using a backup roll, whereby a desired amount of the coating liquid is applied to the web, a liquid supply device having an inclined surface that is inclined downward toward the roll surface and a gap too narrow for the coating liquid to flow down between the roll surface and the inclined surface is provided at a position near the bead portion on the upstream side in the direction of rotation of the gravure roll so that the coating liquid flows down on the inclined surface and is supplied to the gravure roll. A liquid return of an excess coating liquid that is not used for coating in the bead portion is less liable to occur, so that a streak trouble on a coating surface formed on the web can be prevented from occurring.
