ABSTRACT:
A spiral-link fabric for use in a papermaking machine or the like. The spiral-link fabric may include a plurality of spiral coils arranged in a predetermined manner such that adjacent ones of side-by-side spiral coils are interdigitated with each other so as to form a channel and interconnected by a pintle extending through the channel. At least some of the plurality of spiral coils have a coil width of approximately 12 mm or larger. The ratio of coil thickness to coil width may be approximately 0.5 or less.
