Abstract
Abstract A fabric is produced in a stitch-through type machine such as a Malimo machine 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° 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 substate and design elements against relative displacement and to form thereby an integrated fabric structure. The apparatus for guiding the warp yarn design elements onto the flexible substrate in a twisted and aesthetically pleasing configuration at spaced intervals along the warp direction includes at least one shaft rotatable about its longitudinal axis to which is joined a guide bar having a number of spaced-apart warp yarn guides. The apparatus is adapted to be mounted on the machine for rotation of the shaft about its axis in synchronization with reciprocal linear movement of the shaft along said axis. In the present method of producing the fabric, a plurality of adjacent design elements are twisted at spaced time intervals by means of the herein disclosed apparatus at a location upstream from the point at which the substrate and design elements are joined by the knitting thread.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
126 words
In a fabric made on a stitch-through type machine such as a Malimo machine, including a flexible substrate at least two yarn design elements laid on the substrate in the warp direction, and knitting thread forming a multiplicity of warpwise loop chains which bind together into an integrated structure the substrate and the design elements and to secure the substrate and design elements against relative displacement, the improvement in combination therewith wherein one or more of said design elements in one position cross over on top of one or more adjacent design elements and, in a second position, cross back over said one or more adjacent design elements for providing an aesthetically pleasing appearance corresponding to a twisted configuration of said design elements at spaced intervals.
Claim 2
Dependent Claim
126 words
In a fabric made on a stitch-through type machine such as a Malimo machine, including a flexible substrate at least two yarn design elements laid on the substrate in the warp direction, and knitting thread forming a multiplicity of warpwise loop chains which bind together into an integrated structure the substrate and the design elements and to secure the substrate and design elements against relative displacement, the improvement in combination therewith wherein one or more of said design elements in one position cross over on top of one or more adjacent design elements and, in a second position, cross back over said one or more adjacent design elements for providing an aesthetically pleasing appearance corresponding to a twisted configuration of said design elements at spaced intervals.
