Claims12
An endless power transmission belt for operation in an endless path comprising, a tension section, a compression section, and a load-carrying section, said load-carrying section being a flat strip of rubber bonded between said tension and compression sections and having a plurality of elongated discrete fibers embedded therein, said compression section comprising a fiber-loaded platform layer providing transverse rigidity for said belt.
A method of making endless power transmission belts each for operation in an endless path comprising the steps of, wrapping a first uncured rubber layer around a cylindrical drum, wrapping a layer of uncured fiber-loaded rubber against said first layer, wrapping a second uncured rubber layer against said fiber-loaded layer, said layers defining a tubular belt-defining sleeve, curing and cooling said sleeve, and cutting said sleeve after curing and cooling thereof to define a plurality of said belts each having a load-carrying section defined by a portion of said fiber-loaded layer and having a tension and compression section defined by a portion of an associated one of said rubber layers.
