  • Patent number: 4192160
    Abstract: A fabric is produced in a stitch-through type machine such as a Malimo maching using the apparatus and method of the invention which has at least two warp yarn design elements laid on a flexible substrate (e.g., a layer of textile filling elements) along rectilinear or non-rectilinear paths and on which a plurality of adjacent design elements are twisted (e.g., symmetrically at 180.degree. per twist) in an aesthetically pleasing configuration at spaced intervals along the warp direction. The design elements are bound to the substrate by knitting thread which forms a multiplicity of warpwise loop chains (e.g., a half-tricot stitch) to secure the substrate and design elements against relative displacement and to form thereby an integrated fabric structure.
