ABSTRACT:
A conveyor belt and drive structure are disclosed for use with a conversion press in which an upper level of an endless conveyor belt is positioned between upper and lower tooling in the press. The conveyor belt includes a plurality of transversely and longitudinally spaced shell-receiving carrier apertures. The shell-receiving apertures are arranged in longitudinally oriented offset lanes lengthwise of the belt for receiving and conveying shells between the tooling of the press. The conveyor belt is driven in stepped fashion by a drive drum having a plurality of circumferentially spaced outwardly extending pins and the conveyor belt is provided with pin receiving holes for engagement by the drive pins. The pin receiving holes are arranged in lanes parallel to the lanes of carrier apertures, either outside of or between those lanes, and the drive holes are spaced from each other a distance at least twice the longitudinal spacing between adjacent carrier apertures. This provides an optimum number of drive holes and places them in the approximate center of regions of the belt where the drive holes are surrounded by the greatest possible width of material.
