ABSTRACT:
A slide-fastener support tape is formed with a Raschel knitting machine having a pair of needle bars. A relatively thin first warp yarn is chained with both of the needle bars to form a longitudinally extending double wale. A plurality of relatively thin second warp yarns are chained with only one of the needle bars into an array of longitudinally extending and transversely spaced single wales spaced by a gap from the double wale. A relatively thick warp yarn is blind lapped into this gap and is held thereon on one side by a weft yarn lapped by one of the needle bars between the double wale and the single wale at the edge of the array and on the other side by another weft yarn lapped by the other needle bar between the double wale and the edge single wale. In addition a plurality of weft yarns are laid into the single wales.
