Abstract
A blank wire of a generally Y-shape cross section is supplied intermittently at a predetermined pitch, during which the blank wire is successively cut transversely into slices of a predetermined thickness. A bulge is formed at a time for a head portion of each of the successive coupling elements and the resulting individual coupling element is collected. Subsequently to the forming of the individual bulge, opposite leg portions of the individual coupling element are pre-clenched to such an extent as to prevent any crack from occurring in a possible surface-treated section of the coupling element when the opposite leg portions are clenched for attaching the coupling element to a slide fastener tape.
