Abstract
Abstract A fabric having a layer of substantially spaced apart design elements which are laid on a cloth substrate, in the warp direction. along nonlinear paths is disclosed. The design elements are affixed to the substrate and other optional components of the fabric by knit-stitching with parallel rows of stitches forming a series of loop chains.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
101 words
A fabric made on a stitch-through type machine such as a Malimo machine comprising a flexible substrate, a plurality of substantially spaced apart design elements laid on the substrate along nonlinear paths in the warp direction, each design element including portions of substantial length extending non-parallel to the warp direction, and knitting thread forming a series of warpwise loop chains which bind together into an integral structure the substrate and the design elements and which pierce the substrate and pierce the individual design elements at a substantial number of random points to secure the substrate and design elements against relative displacement.
Claim 2
Dependent Claim
101 words
A fabric made on a stitch-through type machine such as a Malimo machine comprising a flexible substrate, a plurality of substantially spaced apart design elements laid on the substrate along nonlinear paths in the warp direction, each design element including portions of substantial length extending non-parallel to the warp direction, and knitting thread forming a series of warpwise loop chains which bind together into an integral structure the substrate and the design elements and which pierce the substrate and pierce the individual design elements at a substantial number of random points to secure the substrate and design elements against relative displacement.
Claim 3
Dependent Claim
26 words
The fabric of claim 1, wherein alternate loops in each chain are formed with a different thread, and each thread forms a series of loop chains.
Claim 4
Dependent Claim
15 words
The fabric of claim 2, wherein the knitting thread is applied as a tricot stitch.
Claim 5
Dependent Claim
13 words
The fabric of claim 1, wherein the flexible substrate is a knitted fabric.
Claim 6
Dependent Claim
13 words
The fabric of claim 1, wherein the flexible substrate is a woven fabric.
Claim 7
Dependent Claim
14 words
The fabric of claim 1, wherein the flexible substrate is an elastomeric foam sheet.
Claim 8
Dependent Claim
17 words
The fabric of claim 1, wherein the flexible substrate is at least one layer of textile elements.
Claim 9
Dependent Claim
13 words
The fabric of claim 7, wherein the layer of textile elements is filling.
Claim 10
Dependent Claim
17 words
The fabric of claim 2, wherein the flexible substrate is at least one layer of textile elements.
Claim 11
Dependent Claim
24 words
The fabric of claim 1, wherein the design elements include portions of substantial length extending diagonally, relative to the warp directions, along straight lines.
Claim 12
Dependent Claim
17 words
The fabric of claim 1, wherein the design elements include portions of substantial length curving substantially uniformly.
Claim 13
Dependent Claim
25 words
The fabric of claim 1, wherein the design elements are disposed in groups composed of at least two adjacent design elements following an identical pattern.
Claim 14
Dependent Claim
12 words
The fabric of claim 1, wherein adjacent design elements form different patterns.
Claim 15
Dependent Claim
21 words
The fabric of claim 1, wherein adjacent design elements form the same pattern but one is reversed relative to the other.
