CONSTITUTION:The lower mold 5' of a press is fixed, while the upper mold 5 of the press is made movable upward and downward. The under surface of the upper mold 5 of the press has been finished in tiers, which consist of a set of small inclined planes 9 and a punching die 10 is provided in the central portion. The width of the lower mold 5' of the press is set equal to that of the strip 1, while the depth of the walls 14, 14' of groove provided below the side walls 15, 15' is set to such an extent that both the ends of the strip are not detached from the lower mold even if the width of the strip fluctuates.
