A method for manufacturing an endless V-type transmission belt having an inner compression section, an outer tension section and a load-carrying section positioned between said compression section and said tension section which comprises the steps of;
- placing a layer of uncured rubber around a first forming member to form a compression section, applying a load-carrying section around said uncured rubber layer, applying a plurality of layers of fabric around said load-carrying member to form a tension section, placing a second forming member around said fabric layers, said second forming member having corrugations in its inner surface and forming corresponding corrugations in at least two of said layers of said fabric in said tension section at approximately right angles to said load-carrying member, vulcanizing the resulting assembly to complete the corrugations, and cutting the vulcanized assembly into a plurality of finished belts.
An endless V-type transmission belt comprising an inner compression section, an outer tension section and a load-carrying section positioned therebetween, said tension section comprising a plurality of layers of fabric having molded corrugations transverse of the endless path of said belt wherein at least two of said layers of said fabric generally follow the same convolutions.
