A lehr loader (20) for transferring a line of freshly formed glass containers (C) on a cross-conveyor (XC) transversely of the cross-conveyor into an annealing lehr (L). The lehr loader has a superimposed stack of three carriages (48, 76, 94), an enclosed linear actuator (50) in the form of an enclosed ball screw mechanism with a housing (56) is attached to the frame, and a reversible, co-axial a.c. servo motor (52) is provided to cause reciprocation of the lowermost carriage. An enclosed linear actuator (78) in the form of an enclosed ball screw mechanism with a housing (82) attached to the lowermost carriage (76) and a co-axial reversible, a.c. servo motor (80) is provided to cause reciprocation of the intermediate carriage. An enclosed linear actuator (96) in the form of an enclosed ball screw mechanism with a housing (102) attached to the intermediate carriage (76) and a reversible, a.c. servo motor (98) is provided to cause reciprocation of the uppermost carriage (94).
