Abstract
Abstract A multilayer textile article for the production of laminated materials has layers each consisting of a two-directional cloth, the layers being joined together by a third thread extending in a direction inclined to the direction in which the threads of the layers extend. According to the invention the third thread forms a continuous stitching (C), the stitching extending helically from one end of the layers to the other.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
128 words
A three-dimensional multilayer textile article comprising: a plurality of superposed elementary layers each of which layers comprises a plurality of first threads extending in a first direction and a plurality of second threads extending in a second direction, said first and said second directions being non-parallel, and said layers being superposed and collectively having a three-dimensional shape in the article, the three-dimensional shape defining first and second end portions of the layers and corresponding to a body of revolution; and a third thread joining said layers together, said third thread extending in said layers in a third direction that is non-parallel to each of said first and said second directions, and helically across said superposed layers from said first end portion thereof to said second end portion thereof.
Claim 2
Dependent Claim
128 words
A three-dimensional multilayer textile article comprising: a plurality of superposed elementary layers each of which layers comprises a plurality of first threads extending in a first direction and a plurality of second threads extending in a second direction, said first and said second directions being non-parallel, and said layers being superposed and collectively having a three-dimensional shape in the article, the three-dimensional shape defining first and second end portions of the layers and corresponding to a body of revolution; and a third thread joining said layers together, said third thread extending in said layers in a third direction that is non-parallel to each of said first and said second directions, and helically across said superposed layers from said first end portion thereof to said second end portion thereof.
Claim 3
Dependent Claim
37 words
A three-dimensional multilayer textile article as claimed in claim 1, wherein the pitch of said third thread extending helically is uniform from said first end portion of said superposed layers to said second set end portion thereof.
Claim 4
Dependent Claim
35 words
A three-dimensional multilayer textile article as claimed in claim 1, wherein the pitch of said third thread extending helically varies from said first end portion of said superposed layers to said second end portion thereof.
