<P>PROBLEM TO BE SOLVED: To provide a method of producing coating rod capable of eliminating a scratch and coating irregularities on the web. <P>SOLUTION: The method includes the steps of: preparing a rod material; arranging paired rolling dies each having a plurality of convex shapes formed on an outer perimeter surface, having a chamfer part, a parallel part, and a relief part from an approaching side toward an exiting side of the rod material, and having a relief angle formed by a surface forming the relief part and a surface of the parallel part of 0.01-0.45° so that the parallel parts face each other; inserting the rod material from the chamfer part side in a space interposed between the paired rolling dies; and forwarding the rod material to a relief part side by the paired rolling dies pressuring the rod material therebetween while rotating and performing a rolling process on a surface of the rod material. <P>COPYRIGHT: (C)2013,JPO&INPIT |
