Abstract

A coating device has: a die head that is provided with a supply port into which a coating slurry is supplied, a manifold that stores the coating slurry, and a slit that dispenses the coating slurry; a supply pipe that is connected to the supply port of the die head; and a cover plate that is provided in the supply port or the supply pipe and that reduces the flow rate of the coating slurry at the center of a cross-section that is orthogonal to the direction in which the coating slurry in the supply port or the supply pipe flows into the die head.

First claim

What is claimed is:

1. A coating method that uses a coating device comprising at least:
a die head including a supply port into which a coating slurry is supplied,
a manifold that stores the coating slurry, a slit that dispenses the coating slurry that is stored in the manifold, and
a supply pipe having one end connected to the supply port and another end connected to a gate valve that switches between supplying and cutting off the coating slurry, said method comprising:
reducing, more in a center than at a periphery of a cross-section of the supply pipe that is orthogonal to a direction in which the coating slurry flows in the supply pipe, a flow rate of the coating slurry through the cross-section of the supply pipe;
maintaining a flow rate of the coating slurry in a vicinity of a wall surface of the supply pipe; and
supplying the coating slurry to the supply port.
