  • Patent number: 8875745
    Abstract: A fabric for forming a fibrous paper web having an embossed surface is provided that includes at least longitudinal and transverse threads interwoven with one another in a weave repeat defining a machine side and a paper side. Some of the longitudinal threads form embossing threads having projecting paper side floats on the paper side of the fabric passing over more than one transverse thread. The fabric includes at least a first woven fabric layer forming the paper side on its outside and having longitudinal and transverse first threads interwoven with one another and a second woven fabric layer forming the machine side on its outside and having longitudinal and transverse second threads interwoven with one another. At least some of the longitudinal second threads form embossing threads, which penetrate the first woven fabric layer for forming the paper side floats and connect the two woven fabric layers.

  • Patent number: 8640741
    Abstract: A woven papermaker fabric having a first woven fabric layer made of first threads and having a second woven fabric layer made of second threads, the two woven fabric layers being connected by binder threads formed by structural second threads at binder points and having knuckles having peaks constituting a peak plane parallel to a paper side plane, and the first threads forming knuckles with concave inner bends, the points of which lying nearest to the paper side plane constituting an inner plane, wherein the tension of the first threads extending transversely to the binder threads is such that the peak plane is nearer to the paper side plane than the inner plane thereby causing lateral deflections of at least one of the first threads.
