Abstract
An extrusion type coating apparatus for applying a coating film to a support has a bent doctor edge made of cemented carbide having a very large hardness. The bent doctor edge has a very large obtuse angle and the resulting doctor edge allows the coating film to be applied smoothly to the support. Since the doctor edge is made of cemented carbide having a very high hardness, the doctor edge is not unduly worn by abrasives contained in the coating film thereby improving the wear-resistance of the apparatus.
