Abstract:
When a coating material is rolled between rolls to generate a a coating film, and the coating film is transferred onto the coating object, at first, a residual coating material layer based on a residual coating material is formed on each of the surfaces of the rolls, and supply of the coating material and transfer of the coating film are carried out in a state where the residual coating material layer is retained on each of the surfaces of the rolls, thereby suppressing abrasions between the rolls and the coating material.
