Each conveyor assembly has a detachable connection (46) to a drive mechanism (48) of the lower support to provide rotational driving of a roller (41 or 43) or wheel (44) of each conveyor assembly. An actuator (62) provides relative vertical movement that lifts the heated preformed glass sheet received by the conveyor (36) to provide press bending thereof between a lower press ring (52) and an upper press mold (58).
