  • Patent number: 10022743
    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.

  • Patent number: 9724726
    Abstract: A high-quality coating film with a uniform thickness is produced without crush of coating particles even in a case where a wet coating material that does not require a step of drying the coating material is used, while maintaining high productivity. By providing a surface layer with an optimized hardness on the surface of a roll used for supply of a mixture coating material, a high-quality coating film with a uniform thickness can be produced, even in a case where a wet coating material that does not require a step of drying the coating material is used, while maintaining high productivity.

  • Patent number: 9694382
    Abstract: A manufacturing apparatus of a coating film product rolls a mixture coating material by a first roll and transfers the mixture coating material to a coated object in motion to thereby manufacture the coating film product. An arithmetic average roughness Ra on a roll surface of the first roll is higher than a value 0.05 times of a particle size “d10” in which an integrated distribution of particle sizes of particles included in the mixture coating material is 10% and lower than a value 20 times a particle size “d90” in which an integrated distribution is 90%.

  • Publication number: 20150238994
    Abstract: A manufacturing apparatus of a coating film product, which rolls a mixture coating material containing a solvent by using a roll and transfers the mixture coating material to a moving coated object to thereby manufacture the coating film product, in which plural rolls are provided, a surface contact angle between a first roll which transfers the mixture coating material to an adjacent second roll and the solvent is larger than a surface contact angle between a roll surface of the second roll and the solvent concerning the first roll and the second roll in the plural rolls, and the surface contact angle between the roll surface of the second roll and the solvent is larger than a surface contact angle between a coated-object surface of the coated object and the solvent concerning the second roll in the plural roll and the coated object.
