(Effects of the Invention) The gravure coating apparatus of the present invention includes two coating roll apparatuses, which are composed of a gravure roll, a coating liquid pan, and a doctor blade, arranged in series in the sheet traveling direction at appropriate intervals,
Between one coating roll device and the other coating roll device,
Since it is provided with an impression cylinder roll that is moved by the reciprocating device and selectively presses either one of the gravure rolls, the pressing roll device is not required to be reciprocally moved as a whole. When the impression cylinder roll is moved by the reciprocating device by passing the sheet between the cylinder roll and the gravure roll, the impression cylinder roll holds the sheet in motion, and the gravure roll of one coating roll device or the gravure roll of the other coating roll device is held. It is possible to transfer and apply the coating liquid onto the sheet by pressing either one of the rolls. Therefore, the coating conditions can be changed and the maintenance can be performed without stopping the sheet that is continuously running, and the operation rate is improved by eliminating the operation stop due to the type change and the maintenance work.
