  • Patent number: 4691370
    Abstract: A bulk material bag includes an inner bag united with a cover bag. One tape of a closed slide fastener overlaps the interior of an inner bag rear top extension and is secured thereto. The top extension, together with the attached closed slide fastener and a rear top cover bag flap is folded over the front face of the cover bag and the second tape of the slide fastener is secured to the front face of the cover bag and the flap is secured to the front face of the cover bag and covers and protects the slide fastener until the initial opening of the bulk material bag.

  • Patent number: 4426066
    Abstract: An invisible slide fastener includes thermoplastic slide fastener elements secured to folded-back portions of the mounting tapes. The slide fastener elements are molded onto the tapes so that integral fastening extensions of the fastener elements extend through an open mesh area of each tape. The slide fastener elements include an interlock structure which is particularly resistant to movement between the opposite rows of slide fastener elements.

  • Patent number: 4348245
    Abstract: Successive portions of a continuous polymer filament are plasticized such as by localized heating with ultrasonic or thermal energy, and the plasticized portions are molded in one or more cavities to form articles such as slide fastener elements. Additionally there is disclosed the attachment of a thermoplastic slide fastener coupling element to the edge of a tape by surrounding the leg portions with walls of cavities in a pair of ultrasonic members and applying ultrasonic energy through energy directing projections located centrally within the cavities to the pair of legs to fuse the legs to the edge of the tape.

  • Patent number: 4324033
    Abstract: Slide fastening elements mounted on longitudinal connecting and supporting means woven in the edge of a supporting tape with pluralities of loops of weft thread segments passing around the connecting and supporting means between the fastening elements, are removed by cutting the connecting and supporting means on opposite sides of each fastening element of a group of the fastening elements to be removed, and pivoting the group of fastening elements and severed ends of the connecting and supporting means about an axis extending parallel the tape and spaced from the tape and the connecting and supporting means to pull the group of fastening elements and severed ends of the connecting means from the weft thread loops.

  • Patent number: 4259272
    Abstract: Successive portions of a continuous polymer filament are plasticized such as by localized heating with ultrasonic or thermal energy, and the plasticized (plastified) portions are molded in one or more cavities to form articles such as slide fastener elements. Additionally there is disclosed the attachment of a thermoplastic slide fastener coupling element to the edge of a tape by surrounding the leg portions with walls of cavities in a pair of ultrasonic members and applying ultrasonic energy through energy directing projections located centrally within the cavities to the pair of legs to fuse the legs to the edge of the tape.

  • Patent number: 4091532
    Abstract: In gapping a stringer of a slide fastener, a plurality of interlocking elements in a portion to be gapped are gripped, such as by a comb, while the tape is clamped or held, and then relative movement is produced between the gripped fastening elements and the held tape either by moving the gripped elements or the held tape with a pivoted motion to pull the gripped elements seriatim from the tape.

  • Patent number: 3999256
    Abstract: A fastening device used in shoe and related closures has a V-shaped resilient wire attached to the opened closure flaps which may be drawn together by sliding a second wire member which is wrapped about it along the diverging portions. The two wire members are both hingedly received within a manipulating member and are retained in place by deforming parts of the manipulating member.
