A conveyor belt and drive structure are disclosed for use with a conversion press in which an upper level of an endless metallic conveyor belt, preferably of stainless steel, is positioned between upper and lower tooling in the press. The conveyor belt is formed by seam welding together the ends of a length of thin flexible metal, and includes a plurality of transversely and longitudinally spaced shell-receiving carrier apertures. The edges of the conveyor belt at the ends of the weld seam are relieved with an elongated notch shape having corners formed on a radius to eliminate from the belt stress concentrations which may occur during the welding process.
