摘要
Manufacturing of a sipe blade (B) at a low cost and in a short time, and shortening of a manufacturing period and reduction in cost of a tire vulcanizing mold (M) are achieved. A metal wire material (1) is subjected to rolling and molding processing, and subsequently is subjected to heat treatment to form an intermediate material (1A-1D). The intermediate material (1A-1D) is cut off and a hole (18) is formed therein, and the sipe blade (B) is thereby manufactured. IMAGE IMAGE
