Abstract

PURPOSE: To sharply shape the coner parts of the convexity of a product, by inserting a face film between male and female dies, and pressing an elastic tip into a concavity formed by shaping the face film to a desired uneven pattern to fuse and bond the face film and the elastic tip in one body.
CONSTITUTION: A compressing member 6 of a lower die 3 is lowered, a desired amount of an unvulcanized urethane tip 8 is filled into a portion surrounded with projecting walls 4 and a cylinder wall 5, and a face film 10 is inserted between an upper die 1 and the lower die 3. The upper and lower dies are moved relatively to form the face film to an uneven pattern. The corner edge parts of the convexity 11 of the face film 10 is shaped sharply by the top ends of the projecting walls 4. The compressing member 6 positioning at the side of the cylinder wall 5 in the lower die is lifted and carried to the lower end position of the convexity 11 of the face film 10, while the elastic tip 8 is heated, compressed and melted. Consequently, the tip 8 and the shaped face film 10 are assembled in one body.
