Abstract
A coating method for coating a coating liquid on a base by supplying the coating liquid between a rotating bar and the base, wherein the coating is executed while a film, having a thickness equal to or less than twice the coating thickness of the coating liquid to be coated on the base, is positioned between the bar and the base so as to cover the bar, thereby forming an uncoated area.
Claims15
A coating method for coating a coating liquid on a transported coating medium to be coated by supplying the coating liquid between a rotating bar and the coating medium,
- wherein the method comprises executing the coating while a film, having a thickness equal to or less than twice the coating thickness of the coating liquid to be coated on the coating medium, is positioned between the bar and the coating medium so as to cover the bar, thereby forming an uncoated area, and
- wherein the coating liquid has a viscosity of 8 cp or less and a surface tension of 30 dyne/cm or less.
A coating apparatus for coating a coating liquid on a transported coating medium to be coated by supplying the coating liquid, the coating apparatus comprising:
- a pass roller that guides the transported coating medium;
- a coating member provided with a rotating bar that is brought in contact with the transported coating medium and serves as a coating nozzle when coating the coating liquid;
- and
- a film that hangs over a part of the rotating bar to form an uncoated are
- wherein the film has a thickness equal to or less than twice the coating thickness of the coating liquid to be coated on the coating medium, and
- wherein the coating liquid has a viscosity of 8 cp or less and a surface tension of 30 dyne/cm or less.
