Abstract
An adjustable brassiere metal-free back fastener is formed by molding eyelets and studs on ultrasonically or mechanically pierced fabric tapes composed of polyamide yarn which is partly enfolded in an outer tape ultrasonically welded to the inner tape. No stitching is required in the fabrication of the fastener and because the coupling members and the thermoplastic yarn can be of the same polyamide material, the product can be uniformly dyed.
Claims12
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.
A method of making a 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 synthetic resin coupling members to form a fastener strip;
- (b) enfolding said fastener strip in a second elongated knit web of a thermoplastic yarn so that edge portions of said second web overlie one face of said fastener strip alongside said succession of coupling members and another portion of said second web covers the other face of said fastener strip;
- (c) ultrasonically joining said edge portions to said fastener strip and said fastener strip to said other portion of said second web at longitudinally spaced-apart intervals along said fastener strip at which said coupling members 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 coupling members whereby said lengths can be affixed to a garment for engagement of a complementary coupling member in the respective coupling member of the fastener band to secure the garment.
