Element row for a slide fastener and method and apparatus for producing the element row of synthetic resin monofilaments and to form the element row.

摘要

The present invention provides A ROW OF ELEMENTS FOR SLIDING CLAMP, OBTAINED BY STAMPING monofilament WORKED WITH SYNTHETIC RESIN, and wherein the coupling heads are formed in configurations PECULIAR INSULATION IN ORDER TO ALLOW THE ELEMENTS are engageable SO RELIABLE each other, ALTHOUGH SMALL SPACES ARE AMONG THE TOP PARTS AND LOWER LEGS AND LASTING ELEMENT SEA AND HAVE A SUFFICIENT coupling function, and provides a method and an apparatus for producing the item. EACH coupling head (2) of a continuous element row (ER) MOLDED BY STAMPING, HAVE PARTS OF SECTION PLANE (2A), EACH OF WHICH EXTENDS FROM CENTRAL PORTIONS OF SOME EXTREMES OF THE PARTIES TO TOP LEGS AND BOTTOM (3), IN MUTUAL STEERING widths increasing in longitudinal direction of the elements and coupling portions (2b) REMAIN IN SANDWICH BETWEEN THE TWO PARTS OF SECTION FLAT (2A), eXTENDING ALONG EDGES opposite eND OF THE PARTIES TO SECTION PLANE (2A), fINER THAN PARTS OF SECTION PLANE (2A) and having portions tip end projecting toward opposite sides CLOCKWISE LONGITUDINAL element row (ER ) and finding the engaging portion (2B) CONNECTED rELIABLY a small space between Hose Couplers (2) AND PARTS OF UPPER LEGS AND LOWER (3) OF THE aDJACENT ELEMENTS OF A ROW OF ELEMENTS MATCHING IN HE TIME coupling element rows COUPLING MATCHING (ER) IN A STATE THAT MAKES THE PARTIES (3) OF THE UPPER LEGS AND LOWER element row are set to tape fastener almost intimate contact with each other. ACCORDINGLY, NO SEPARATION IS GENERATED A coupling or similar effect.
