Abstract

PURPOSE: A coating blade designed to extrude a coating material into a uniform film over the whole width, comprising a first well, a narrowed channel, and a second well having a slit outlet.

The material A is then passed through the channel 30 and widened in the second well 20, then extruded through the slit outlet 21 uniformly in the width directin to coat the member 60.
