  • Patent number: 4776373
    Abstract: A fabric for the sheet forming section of a papermaking machine comprising two layers of transverse threads and longitudinal threads interwoven with both layers of transverse threads. Both the paper side and the running side have a transverse structure, and the number of transverse threads in the upper layer is twice as high as that in the lower layer. The longitudinal threads interweave twice in each repeat with the upper layer and with the lower layer. Interweaving with the upper layer is effected one time with a transverse thread laying directly above a transverse wire of the lower layer and the other time with a transverse thread disposed between and above two transverse threads of the lower layer.
