Claims19
An apparatus for installing a slide fastener to material, the slide fastener having a pair of carrier tapes and opposed interengaged fastening elements with each one of the elements being secured to its respective one of the adjacent edges of the pair of carriage tapes, said apparatus comprising
- a support block means,
- a first pair of laterally spaced pins disposed at one end of said block means,
- a second pair of laterally spaced pins disposed at the opposed end of said block means and spaced at a longitudinal distance less than the length of the slide fastener from said first pair of pins,
- each pin of said first or second pair being laterally spaced relative to the other pin of its respective pair at a distance greater than the overall width of the interengaged elements of the slide fastener, and
- said first and second pairs of pins adapted for piercing certain opposed and spaced end portions of the adjacent edges of the carrier tapes of the slide fastener so as to effect securing of the slide fastener to said first and second pairs of pins while at the same time to effect substantially flat nesting engagement of the secured slide fastener on said block means prior to attachment of the material to the slide fastener.
A method of installing a slide fastener to material, the slide fastener having a pair of carrier tapes with adjacent edges and opposed interengaged elements each each one of the elements being secured to its respective adjacent edge of the carrier tapes, the method utilizing a slide fastener support block means, first and second pairs of spaced pins for engaging the slide fastener, the first and second pairs of pins disposed at opposite ends of said block means and spaced at a longitudinal distance from each other, said method comprising the steps of
- feeding a slide fastener having a length greater than the longitudinal distance between said first and second pairs of pins,
- centering the fed length of slide fastener relative to the first and second pairs of pins such that the opposed interengaged filaments of the slide fastener are interposed between and spaced from the first and second pairs of pins,
- piercing certain opposed and spaced end portions of the adjacent edges of the carrier tapes of the fed and centered slide fastener with the first and second pairs of pins so as to effect securing of the slide fastener to the first and second pairs of pins while at the same time to effect substantially flat nesting engagement of the secured slide fastener on said block means prior to securing of the material to the slide fastener, and
- securing the slide fastener to the material.
