Abstract
A toothed belt having an endless rubber band formed with projecting tooth portions, the rubber band having tension members buried in parallel therein. A cloth cover is fastened to the toothed surface of the band. The cloth is formed of woven fibers, and one of the warp and woof fibers of the cloth has a high-adhesive characteristic, and has a greater exposed surface area on one side of the cloth, which side is fastened to the toothed surface. The other of the warp and woof is formed of a fiber having properties suited for the working environment, such as properties of abrasion resistance and low friction, these latter fibers having a greater exposed area on the other side of the cloth, which other side is positioned for engagement with a toothed pulley.
