摘要：
A taper shaped steel rod-like member allows a cold press molding apparatus to reduce burrs generated in tooling without the use of lubrication while also extending tool live. The method and process is characterized by holding the preshaped processed material on a backside tool, while press-contacting the processed material to a free rotation roll rotating toward the tip element on the processed material, and shaping a taper shape by plastic-reshaping of the processed material.
