CHAINE DE FERMETURE A CURSEUR SEPARABLE ET PROCEDE POUR SA FABRICATION |
摘要 |
A separable slide fastener chain comprises a pair of oppositely disposed stringers of continuous length each having a support tape and a fastener element formed from a plastic monofilament into a continuous structure secured by sewn seams to a longitudinal inner edge of the respective tape. The fastener element is fused together over a predetermined length of the two coupled stringers at predetermined intervals. A composite pin-forming structure is located centrally of the fused length of the fastener element and cut out to produce a multi-form aperture having a pair of bay portions extending transversely of the fastener chain and oppositely disposed in point-symmetry relation and a pair of elongated canal portions extending longitudinally closely along the sewn seams. The composite structure is subdivisible across the bay portions into two identical pairs of slider-lock pin members and inserting pin members. |
