Open the CIPO recordAbstract From the Canadian patent
Conveyor belting ends each comprising a pair of, carcass plies separated by an intermediate elastomeric ply and enclosed by a pair of outer rubber plies are spliced by removing, material from various plies to expose one surface of each terminal portion of the carcass plies. The two belting ends are then interfitted, after the application of tie gum to exposed surfaces, such that each carcass ply terminal portion overlies the terminal portion of the associated carcass ply on the other belting end, thereby assuring two uninterrupted carcass plies at the longitudinal location on the belt where each carcass ply is severed.
