Pocket arrangement in the support surface of a woven papermaking fabric

摘要

A woven fabric for use on papermaking machines having first and second sets of filaments interwoven with each other to provide a first grouping of coplanar top surface crossovers and a second grouping of recessed sub top surface crossovers. The first grouping of top surface crossovers are in spaced relation to define a plurality of at least first and second cavities. The first ones of the cavities are arranged along substantially parallel lines in the cross machine direction and the machine direction. The second ones of the cavities are spaced from the first ones of the cavities and are arranged along substantially parallel lines which extend in both the cross machine direction and the machine direction. Individual ones of the first cavities are arranged adjacent of and are interconnected with individual ones of the second cavities. The interconnected first and second cavities form cavity pairs.
