ABSTRACT:
A woven belting has a single-ply central portion and tubular edges which are integrally woven with the central portion as a hollow plain weave; high abrasion resistance is achieved for the tubular edges by shrinking their warp threads to a predetermined extent before the weaving operation. The warp threads in the edges of the belting are subsequently shrunk to their full possible extent during a final heat setting treatment of the whole belting.
