ABSTRACT:
In a duplex type coating apparatus, a left-right pair of dies and are disposed on opposite sides of a carrying path of a web, the dies and are each made up of an upper member and a lower member, a tip part of the lower member projects further toward the carrying path than a tip part of the upper member, and coating liquid discharge passages are inclined in the direction of the carrying path of the web. As a result, because the same amount of coating liquid is discharged from each of the dies and coated onto each side of the web, it is possible to carry out coating at the same coating thickness and in the same position on both sides of the web.
