    摘要： A paper including one or more multi-tonal watermarks having full tonality (depth), and an improved watermarking tool for manufacturing such paper, is provided. The improved watermarking tool is selected from the group of: (a) an assembly that is made up of an electrotype element representing a halftone image of a watermark, and a wire-mesh for use in the manufacture of watermarked paper, wherein the electrotype element is affixed to the wire-mesh, and wherein the electrotype element and the wire-mesh are pressed or embossed, either separately or together in register, with the image of the watermark represented by the electrotype element; and (b) an enhanced wire-mesh made up of woven wires which may be arranged in a regular or substantially regular grid, wherein areas of the grid are filled with a polymeric material which forms regions of blocked drainage, wherein the wire-mesh including open areas as well as those areas filled with the polymeric material are pressed or embossed either separately or together with an image of a watermark.

    摘要： Disclosed are woven papermaking fabrics having a textured sheet contacting surface with machine and cross-machine direction topography. The machine direction (MD) topography may be imparted by substantially MD oriented protuberances comprising a warp strand supported by a shute strand. The cross-machine direction (CD) topography may be imparted by substantially CD oriented protuberances comprising a shute strand supported by a warp strand. The CD protuberances may extend continuously in the CD and intersect the MD oriented protuberances to form discrete pockets there between. The pockets may have a variety of shapes and size depending on the MD and CD oriented protuberance. In certain instances the pockets may be rectilinear and have a pocket depth greater than 1.0 mm and a pocket angle greater than 28 degrees.

    摘要： The present invention relates to papermaking fabrics useful in the manufacture of paper products, such as tissue paper. Particularly this invention relates to a woven papermaking fabric that includes a stabilized weave providing a textured contacting surface. The woven papermaking fabric includes a plurality of warp and shute filaments woven together to provide at least one protuberance on the web contacting side of the fabric that extends longitudinally over at least five shute filaments. The at least one protuberance is stabilized by including an offset shute float weave pattern configured such that a majority of the shute filaments forming the at least one protuberance are woven in an anti-nesting configuration.
