The cloth backing has at least a portion of the fill filaments of the cloth backing at an angle of from 45.degree. to 85.degree. to the warp filaments of the cloth backing and the sections are joined such that at least 30% of the fill filaments are disposed in the running direction of the belt. The invention further comprises the process for making such an abrasive belt by joining appropriate parallelogram shaped sections. The section of abrasive belt of the invention has increased strength in the running direction of the belt and decreased stretch in the running direction of the belt.
