摘要

A spiral link belt for the manufacture of paper has a multiplicity of mutually parallel helices with the windings of successive helices intermeshing in the manner of a zipper, and pintle wires are inserted into the channels formed by the meshing windings. The belt edges are covered by a protective cover consisting of a fabric wrapped about the belt edges and fastened to the spiral link belt. The protective cover can be a double-layer fabric and can have a seven or eight harness weave in which the longitudinal threads pass over four or five transverse threads or pairs of transverse threads.
