Abstract
A permeable industrial fabric is assembled from a plurality of separate tiles into at least two plies, and in which the two plies are held together by jointing structures made integrally with the tiles. In these fabrics, within each tile the jointing structures are incorporated at primary selected locations according a symmetrical pattern, and the apertures in the tiles which provide the required fabric permeability are incorporated at secondary and tertiary selected locations according two more patterns, at least one of which is asymmetrical. This combination of symmetry and asymmetry allows for some control over the permeability of the assembled fabric.
