  • Double layer papermaking forming fabric
    Patent number: 6413377
    Abstract: A double layer papermaking fabric having twice as many paper side cross machine direction yarns as machine side cross machine direction layer. A system of machine direction yarns is interwoven with both cross machine direction layers, with each machine direction yarn forming first and second knuckles on each side of the fabric. The paper side knuckles are woven with uniform spacing and each machine side cross machine direction yarn is passed under by two machine direction knuckles spaced by at least one intermediate machine direction yarn.

  • Papermaking fabric, process for producing high bulk products and the products produced thereby
    Patent number: 5853547
    Abstract: The present invention is an improved 7,3-broken twill, TAD fabric for use in the formation of a paper web. The present invention is also a process of using this fabric to produce a paper product having high bulk and absorbency. Finally, the present invention is the paper product produced in a TAD process using this fabric.

  • Multiplanar single layer forming fabric
    Patent number: 5806569
    Abstract: A papermaking forming fabric having a single layer of machine direction filaments interwoven with smaller and larger diameter cross direction filaments, the larger diameter filaments forming a wear surface on the machine side of the fabric.

  • Two-ply forming fabric with three or more times as many CMD yarns in the top ply than in the bottom ply
    Patent number: 5564475
    Abstract: A papermakers forming fabric having two layers of CMD yarns interwoven with a system of MD yarns to form a multilayer fabric. The paper support surface CMD yarn layer has at least three times as many CMD yarns as the machine contact surface CMD yarn layer. The higher count of upper layer CMD yarns provides an improved paper forming/carrying surface with improved drainage characteristics.

  • Two-ply papermakers forming fabric with zig-zagging MD yarns
    Patent number: 5025839
    Abstract: A two-ply forming fabric having an upper paper carrying/forming layer which comprises twice as many cross machine direction yarns as the lower, machine-side layer. A system of machine direction yarns interweaves in a selected repeat pattern such that a zigzag effect is produced on the underside of the fabric by the machine direction yarns to provide improved drainage. The higher count of upper layer CMD yarns selectively interwoven in a non-twill pattern with 80%-100% cover of MD yarns provides an improved paper forming/carrying surface.
