An improved can end transfer belt drive assembly includes a drum, drive teeth and belt support rings. The assembly also includes a support shaft rotatably supported by bearings within an associated can end press. The drum is fastened to the shaft and includes a cylindrical surface located at a first radius from the rotational axis of the shaft. The support rings are supported by the cylindrical surface in a side-by-side spaced relationship to rotate relative to the drum, and the teeth are fastened to the drum between the rings. This belt drive assembly supports a transfer belt including drive holes, and the assembly transfers the force to move the belt from the teeth to the drive holes without transferring substantial force as a result of friction between the drum and the belt.
