Pocket arrangement in the support surface of a woven papermaking fabric

摘要

Woven support fabric (14) has warp and waft filaments (22:20) interwoven to provide a first grouping of coplanar top surface (20) and a second grouping of recessed sub top surface (26) crossovers forming spaced first and second cavities (30:32:34:36) in parallel lines with individual first and second cavities interconnected forming cavity pairs (40:42) spaced both longitudinally and vertically. Also claimed is ones of the first set of cavities arranged in the fabric direction interconnect with ones of the second set forming the cavity pairs where the second cavity sets appear on alternative sides of the first direction along which the first cavities are aligned.
