Claim:
A fabric belt for a machine for producing a web of fibrous material, comprising: a first fabric layer including a web contact side and formed by interweaving a plurality of warps with a plurality of wefts; and a second fabric layer positioned below said first fabric layer and formed by interweaving a plurality of warps with a plurality of wefts, a ratio of a number of said plurality of warps of said first fabric layer to a number of said plurality of warps of said second fabric layer being one of greater than and equal to 1.5, said first fabric layer and said second fabric layer being connected to each other via a plurality of binder threads, said plurality of wefts of said first fabric layer and said plurality of wefts of said second fabric layer forming a plurality of wefts of the fabric belt, at least a part of said plurality of wefts of the fabric belt being a plurality of binder wefts which form a connection between said first fabric layer and said second fabric layer and which form said plurality of binder threads, a part of said plurality of wefts of said first fabric layer being a plurality of first wefts, another part of said plurality of wefts of said first fabric layer being said plurality of binder wefts, all of said plurality of warps of said first fabric layer being a plurality of first warps, said first fabric layer being formed by an interweaving of said plurality of first warps with said plurality of first wefts and with said plurality of binder wefts, all of said plurality of wefts of said second fabric layer being a plurality of second wefts, all of said plurality of warps of said second fabric layer being a plurality of second warps, said second fabric layer being formed by interweaving said plurality of second warps with said plurality of second wefts, said first fabric layer being connected to said second fabric layer in that said plurality of binder wefts are interwoven with said plurality of second warps, a cross-sectional surface of said plurality of second wefts being in a range of 0.018 mm 2 to 0.284 mm 2 .
