ABSTRACT This invention is in the field of material handling equipment and is specifically directed to the field of conveyor belt constructions and methods of fabricating conveyor belts formed of rubber-like material in which longitudinally extending reinforcing tendon members a such as wire cable are provided. Heavy duty conveyor belts such as are used in mines, quarries and the like are usually formed of rubber or similar material (hereinafter referred to as "rubber-like material") with the rubber-like material being provided with embedded reinforcing members in the form of steel cables or wires for achieving the necessary strength for the particular usage to which the belts are to be employed. It has been conventional practice for many years to embed such cables in the rubber-like body of the belt during the fabrication of the belt member. Prior known conveyor belts of the aforementioned type can be several thousand feet in length and are consequently extremely heavy so that it is necessary that the belts are assem- bled at the conveyor installation site with completed belt sec- tions each consisting of a cured rubber-like belt material in which the embedded tendon members are provided. It has been the previous practice to fabricate from which the cured ready-to-use belt sections are transported to the assembly site and spliced together in end-to-end manner until the complete belt loop formed of the discrete sections is fabricated. The great weight of the conveyor belt material limits the length of each belt section and creates substantial problems of transportation particularly where the belt is to be assembled in remote areas.
