Abstract
Abstract A fabric for a paper machine including warp and weft threads in an atlas binding providing for improved longitudinal and transverse stability. The uppermost points of the warp and weft threads in the direction towards a paper-supporting surface on the fabric are located in substantially a single plane so as to obtain more uniform marking properties for the fabric and to concurrently avoid material deposits thereon.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
93 words
In combination with a paper making machine having a wet paper processing end section, a water-permeable screen located in said machine wet end section and facilitating the wet batching or passage of said wet paper through that section of the machine, said screen being constituted of plastic monofilament warp and weft threads woven into at least a five-shed binding having uniformly distributed binding points, said binding points being spaced and not touching each other, and said screen having the weft counts thereof higher than four-fifths of the current number of the warp threads.
Claim 2
Dependent Claim
