Abstract
Abstract A composite fabric for use as clothing for the sheet forming section of a papermaking machine, which fabric comprises at least two fabric layers (1, 2) interconnected by binder threads (4, 5), and wherein part of the binder threads (4, 5) extend in the warp and weft directions and the threads form an elastic interlayer (3) and wherein each binder thread (4, 5) is interwoven with not more than one of the at least two fabric layers (1, 2).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
80 words
A composite fabric for use as clothing for the sheet forming section of a papermaking machine, said fabric comprising at least two fabric layers interconnected by binder threads and being characterized in that part of the binder threads extend in the warp direction and part of said threads extend in the weft direction and said threads form an elastic interlayer, and in that each binder thread is woven into not more than one of the at least two fabric layers.
Claim 2
Dependent Claim
80 words
A composite fabric for use as clothing for the sheet forming section of a papermaking machine, said fabric comprising at least two fabric layers interconnected by binder threads and being characterized in that part of the binder threads extend in the warp direction and part of said threads extend in the weft direction and said threads form an elastic interlayer, and in that each binder thread is woven into not more than one of the at least two fabric layers.
Claim 3
Dependent Claim
33 words
A composite fabric according to claim 1 further characterized in that the binder threads woven into an upper fabric layer are passed underneath all the binder threads woven into a lower fabric layer.
Claim 4
Dependent Claim
33 words
A composite fabric according to claim 1 further characterized in that the binder threads extending in the warp direction and the binder threads extending in the weft direction are interwoven with one another.
Claim 5
Dependent Claim
55 words
A composite fabric according to claim 3 further characterized in that the binder threads extending in the warp direction are woven partially into an upper fabric layer and partially into a lower fabric layer, while the binder threads extending in the weft direction are only interwoven with the binder threads extending in the warp direction.
Claim 6
Dependent Claim
55 words
A composite fabric according to claim 3 further characterized in that the binder threads extending in the weft direction are partially woven into an upper fabric layer and partially into a lower fabric lawyer, while the binder threads extending in the warp direction are only interwoven with the binder threads extending in the weft direction.
Claim 7
Dependent Claim
40 words
A composite fabric according to claim 1 further characterized in that the binder threads extending in the warp direction are woven into one fabric layer, and the binder threads extending in the weft direction are woven into another fabric layer.
Claim 8
Dependent Claim
33 words
A composite fabric according to claim 6 further characterized in that the binder threads woven into an upper fabric layer are passed underneath all the binder threads woven into a lower fabric layer.
Claim 9
Dependent Claim
33 words
A composite fabric according to claim 6 further characterized in that the binder threads extending in the warp direction and the binder threads extending in the weft direction are interwoven with one another.
Claim 10
Dependent Claim
40 words
A composite fabric according to claim 1 further characterized in that the binder threads are interwoven with a plurality of threads of said fabric layers, said threads of said fabric layers extending in one of the warp and weft directions.
