Abstract
A painting method and a painting apparatus for a band material that prevent a printing defect during a long-time operation by preventing agglomeration and adhesion of a thixotropic paint in a paint pan is disclosed. The liquid paint is discharged to the paint pan as a jet flow from a level lower than a liquid surface of a paint basin toward a bottom of the paint pan, thereby creating a bottom flow along the bottom of the paint pan and an upward vortex from the bottom along a side wall of the paint pan. The liquid paint overflows in an amount corresponding to a supplied amount to the paint pan from a front upper edge of the paint pan in a flowing direction of the bottom flow, thereby flowing the liquid paint continuously in the paint pan toward the front upper edge.
