Coating device, and coating method using said device

Abstract

A coating device is provided which has a bar which coats a coating liquid on a strip-shaped body conveyed in a given direction, and a dam-shaped member disposed at an upstream side of the bar so as to face the bar. Also provided is a coating method which, in the coating device, supplies the coating liquid from between the dam-shaped member and the bar so as to carry out coating. A flow rate of the coating liquid passing through a gap between the strip-shaped body and the dam-shaped member is set to be 3 m/min or more. A flow rate of the coating liquid passing through a gap between the bar and the dam-shaped member is set to be 5 mm/sec or more.

1 . A coating method which coats a coating liquid onto a strip-shaped body conveyed in a given direction, by using a coating device having a bar which coats the coating liquid and a dam-shaped member which is disposed at an upstream side of the bar so as to face the bar, said coating method comprising:
 carrying out coating with a flow rate of the coating liquid passing through a gap between the strip-shaped body and the dam-shaped member being set to be 3 m/min or more.   
     
     
         2 . The coating method of  claim 1 , further comprising the step of carrying out coating with a flow rate of the coating liquid passing through a gap between the bar and the dam-shaped member being set to be 5 mm/sec or more.
