Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
A composite fabric for use as clothing for the sheet forming section of a papermaking machine comprising at least two fabric layers formed by transverse and longitudinal threads and interconnected in that at least part of the transversely extending and, in addition, at least part of the longitudinally extending threads are woven into the upper and into the lower fabric layer, thereby limiting relative movement between the upper and lower fabric layers.
Claim 2
Dependent Claim
72 words
A composite fabric for use as clothing for the sheet forming section of a papermaking machine comprising at least two fabric layers formed by transverse and longitudinal threads and interconnected in that at least part of the transversely extending and, in addition, at least part of the longitudinally extending threads are woven into the upper and into the lower fabric layer, thereby limiting relative movement between the upper and lower fabric layers.
Claim 3
Dependent Claim
44 words
A composite fabric according to claim 1 further characterized in that a portion of the interconnecting threads, between points where the interconnecting threads pass from the upper fabric layer to the lower fabric layer, extend substantially normal to the plane of the composite fabric.
Claim 4
Dependent Claim
17 words
A composite fabric according to claim 2 further characterized in that the interconnecting threads are structural threads.
Claim 5
Dependent Claim
18 words
A composite fabric according to claim 2 further characterized in that the interconnecting threads are interwoven binder threads.
Claim 6
Dependent Claim
17 words
A composite fabric according to claim 1 further characterized in that the interconnecting threads are structural threads.
Claim 7
Dependent Claim
18 words
A composite fabric according to claim 1 further characterized in that the interconnecting threads are interwoven binder threads.
