Provided is a coating method capable of causing a coating material to easily adhere to pointed ends of center members.　This coating method is a method for coating, with the coating material, the center members of subjects to be coated. This coating method includes a pointed end coating step in which a rotary shaft (C) of a coating tank (25) is inclined with respect to the vertical direction, the rotation direction of a rotary disk (38A) is configured to be opposite to the rotation direction of a drum (28A), the rotary disk (38A) and the drum (28A) are rotated in such a manner that the rotation speed of the rotary disk (38A) is higher than the rotation speed of the drum (28A) so as to thereby cause, on a center member group (CG) formed from the plurality of center members, a first circulating flow movement in the form of a vortex flow around the axis of the coating tank (25) and a second circulating flow movement in the form of a vertical spiral flow that is lifted forward in the rotation direction and that subsequently falls due to its own weight, and the coating material is added to a merging portion of these flow movements so as to coat at least the pointed ends of the center members.

The present application provides a method for manufacturing a laminate, which can stably manufacture a laminate including a coating layer having a desired thickness. A method for manufacturing a laminate according to one embodiment includes: a coating step of coating a coating agent on a substrate being conveyed using a coating roll to form a coating layer on the substrate, the coating agent being coated on the substrate based on a ratio of a rotation speed of the coating roll to a conveyance speed of the substrate, i.e., a coating draw ratio; a thickness acquisition step of acquiring a thickness of the coating layer; a calculation step of calculating a difference between the thickness of the coating layer and a prescribed thickness; and a change step of changing the coating draw ratio in the coating step based on the difference between the thickness of the coating layer and the prescribed thickness, the coating step, the thickness acquisition step, the calculation step, and the change step being repeatedly performed while automatically implementing the coating step, the thickness acquisition step, the calculation step, and the change step.
