Abstract:
A method of making a metal-free strap fastener for articles of clothing including brassieres, lingerie and corsetry, comprising the steps of:(a) molding onto a first elongated knit web of a thermoplastic yarn, a succession of eyelets to form a female-fastener strip;(b) enfolding said female-fastener strip in a second elongated web of a thermoplastic yarn so that edge portions of said second web overlie one face of said female-fastener strip alongside said succession of eyelets and another portion of said second web covers the other face of said female-fastener strip;(c) ultrasonically joining said edge portions to said female-fastener strip and said female-fastener strip to said other portion of said second web at longitudinally spaced-apart intervals along said female-fastener strip at which said eyelets are located to form a fastener band; and(d) ultrasonically severing successive lengths from said band, each of said lengths including at least one of said eyelets whereby said lengths can be affixed to a garment for engagement of a male fastener in the respective eyelet to secure the garment.
