ABSTRACT:
An endless metal belt (26) for transporting shells (S) through a press (10) which converts the shells into can ends includes a plurality of shell-carrying apertures (32) and a plurality of drive holes (34). The belt is mounted about a pair of spaced-apart cylindrical drums (22,24), at least one of which is rotatably driven. The drive holes are engaged by drive pins (46) extending outwardly from the drive drum (22). Rotation of the drive drum causes the pins to engage the drive holes and advance the belt with the drum. Each drive hole has a hub (58) which is shaped to conform generally to a tapered and contoured edge (48) of a drive pin. At least a portion of the hub protrudes out of the planar surface (56) of the belt, and the pin edge and the lower surface (62) of the hub are mutually shaped to define rolling contact therebetween with no contact between the pin edge and the inner edge (54) of the drive hole.
