Coating product manufacturing method and manufacturing apparatus

Provides a method of manufacturing a coated product capable of suppressing the occurrence of sagging or cracking in the outer corner of the coated product. The present manufacturing method includes a conveying step of conveying the laminate 5 having the decorative material 3 adhered to the surface 2a of the substrate， and protruding outward from the side surface 2b of the substrate of the decorative material during the conveyance of the laminate. A heating step of heating the bend margin 3a， and an adhesion step of bending the bend margin heated in the heating step during conveyance of the laminate in a non-heating state to adhere to the side surface of the substrate. In the heating step， the bending margin during heating is bent in a half-fold shape toward the side surface of the substrate， and in the bonding step， the bending clearance portion bent in a half-fold shape in the heating step is further bent to adhere to the side surface of the substrate. Provided is a coated product manufacturing method with which the occurrence of sagging or cracking at an outer-corner curved surface part of a coated product can be suppressed. The manufacturing method is provided with: a conveyance step of conveying a laminate (5) in which a cosmetic material (3) is bonded to a surface (2a) of a base material; a heating step of heating a folding margin (3a) of the cosmetic material protruding outward from a lateral surface (2b) of the base material during the conveyance of the laminate; and a bonding step of folding， in a non-heating state， the folding margin that has been heated in the heating step during the conveyance of the laminate and bonding the same to the lateral surface of the base material. In the heating step， the folding margin during heating is folded in a half-folded state toward the lateral surface of the base material. In the bonding step， the folding margin that has been folded in the half-folded state in the heating step is further folded and bonded to the lateral surface of the base material.
