Title:
COATING APPARATUS AND COATING-FILM FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/068190
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a coating apparatus and a coating-film forming method in which, when a coating material having a high viscosity is applied to the circumferential surface of a cylindrical base material and air is blown to flatten the coating film, the processing time is reduced to improve the productivity, and the occurrence of coating unevenness and coating streaks is reduced to improve the quality of the formed coating film. In order to achieve this purpose, the present invention provides a coating apparatus comprising at least one of: a coating means for applying a coating material on the circumferential surface of a cylindrical base material; a rotary driving means for rotating the cylindrical base material about the axis of the cylinder; an airflow jetting means for jetting an airflow to a part of the circumferential surface of the cylindrical base material; and a moving means for making the airflow jetting means movable so that the airflow is jetted to the circumferential surface to which the coating material is applied, wherein a plurality of the airflow jetting means are provided, and the airflow is jetted to the overall area of the circumferential surface, to which the coating material is applied, by the plurality of airflow jetting means, the moving means, and the driving means.
