ADJUSTABLE STRAP FASTENER FOR BRASSIERES AND THE LIKE AND METHOD OF MAKING SAME

摘要

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