ABSTRACT OF THE DISCLOSURE As it is intermittently supplied, a blank wire having a generally Y-shape cross section is cut into slices of a predetermined thickness by a cutting punch, which is fixed to the frame, and a coacting cutting die, which is reciprocatingly movable in the cutting direction. Then a bulge is formed on the head portion of the cut coupling element by a bulge forming die, which is connected with the forward end in stroke direction of the cutting die, and a coacting bulge forming punch, which is movable upwardly and down- wardly. The cutting punch is equipped with preventing means on the upper side of the end of a blade for preventing the cut coupling element from jumping up from the blade, so that a bulge can be formed on the head portion reliably, without giving any damage to peripheral equipments.
