Abstract
A slide fastener is disclosed including mounting tapes each having a warpless area or a void area formed in them near their adjacent edges. Coupling elements are secured onto the edges of the mounting tapes and plugs of material interconnecting the legs of each coupling element extend through the void area or warpless area of the mounting tapes. Interconnecting straps are also formed in the warpless areas linking each adjacent pair of the coupling elements.
Claims9
A slide fastener comprising
- a pair of mounting tapes having adjacent side edges;
- a warpless area formed in each mounting tape proximate the adjacent side edge thereof;
- a plurality of coupling elements mounted on the adjacent side edges of each of the mounting tapes;
- and
- interconnecting straps connecting each of the coupling elements with each of the adjacent coupling elements, the interconnecting straps being formed of the material from which the coupling elements are formed being filled into the warpless areas of the respective mounting tapes.

A slide fastener stringer comprising
- a mounting tape with a side edge;
- a warpless area formed in the mounting tape proximate the side edge thereof;
- a plurality of coupling elements mounted on the side edge of the mounting tape;
- and
- interconnecting straps connecting each of the coupling elements with each of the adjacent coupling elements, the interconnecting straps being formed of the material from the coupling elements being filled into the warpless area of the mounting tape.

A slide fastener comprising;
- a pair of mounting tapes having adjacent side edges;
- a series of voids formed in the mounting tapes and arranged in a longitudinally aligned row proximate the side edge of each of the mounting tapes;
- a plurality of coupling elements mounted on the adjacent side edges of each of the mounting tapes, each of the coupling elements having a pair of legs extending over opposite sides of the mounting tape;
- and
- at least a pair of interconnecting plugs formed in each coupling element extending between the legs of the coupling elements through an adjacent pair of longitudinally aligned voids.
