Woven slide-fastener stringer

In a slide fastener having a stringer half formed with a woven ground-weave tape and a continuous monofilament coupling element woven into said tape during the weaving thereof and wherein said tape has a ground weave comprising ground warp yarns forming warp pockets receiving ground double wefts reaching to a longitudinal edge of the tape and formed by a continuous ground weft yarn, said coupling element comprising a multiplicity of coupling members spaced apart along said edge with each coupling member having a coupling head projecting beyond said edge and a pair of shanks having superposed projections in a slide fastener plane overlying a portion of said tape adjacent said edge with connecting parts bridging the shanks of successive coupling members, the improvement wherein in combination:

• said coupling element is secured to said tape on said portion by a plurality of connecting warp yarns;
• the shanks of each coupling member form a double weft inner woven with said connecting warp yarns;
• respective double wefts underlie each coupling member while interstitial ground double wefts lie between the coupling members;
• said connecting warp yarns are offset longitudinally from one another with a stagger of at least one pick;
• each of said connecting warp yarns overshoots some of said coupling members, passes below the interstitial double weft between overshot coupling members, and then engages below subsequent coupling members between the bottom shank thereof and the double wefts therebelow, and is then secured in the tape portion below the coupling element in a repeating pattern;
• and
• the interstital double wefts disposed between successive coupling members are drawn by at least one of the connecting warp yarns as a ground weft padding loop away from the ground weave at least past the median plane of the coupling to the upper level of said members so that each padding loop substantially fills the space between the pair of respective coupling members and from the connecting parts thereof to a head of another coupling member receivable between the coupling members of said pair.
