A method of making a slide fastener unit comprising weaving a thermoplastic monofilament through the flank portions of each of two Y-tapes, the monofilament of each tape being looped back and forth through the flanks so that the vertical sections between the flanks of one tape are in staggered or alternating relation to those of the other tape, whereafter these vertical sections are folded, embossed in the middle sections, pre-curved on the side sections and molded to fix the shape with the two tapes in fastened position. A novel folding, embossing, pre-curving, molding and ironing apparatus is also disclosed for the continuous manufacture of the slide fastener separately or in conjunction with a conventional weaving loom. |
