Abstract

PURPOSE:To elevate the productivity, by flat-pushing a metallic stem and simultaneously forming an escape groove of a seaming material by a press. CONSTITUTION:On the lower surface of an upper mold 5a and the upper surface of a lower mold 5b, wedge-like projecting lines 6a, 6b are formed in checkerboard pattern on the respective surfaces, and between then, a metallic stem 7, wedge-shaped and groove-like flat-push notches 8a, 8b are molded, and by a flat- push effect in this case, warp of the metallic stem 7 is removed, and it is made a parallel plane. In this case, when press working is performed, simultaneously escape grooves 9a, 9b consisting of the groove-like flat-push notches 8a, 8a', 8b and 8b' continuously molded vertically and horizontally in checkerboard pattern are formed on both the upper and lower surfaces of the metallic stem 7. In this way, the parallel plane and the escape groove are formed at the same time by only performing the press working.
