A heated glass sheet topside support device (22, 22', 22a, 22a') is disclosed as including horizontally extending lower and upper plates (38, 46) connected by a set of vertically extending passage members embodied by tubes (54) or plate members (54a) to define passages (55, 55a, 55a'). The support device also includes first and second manifolds (56, 58) for supplying pressurized gas and a vacuum through first and second sets of holes (42, 42a, 42a'; 44, 44a, 44a') in the lower plate so as to thereby support a heated glass sheet below the lower plate without any engagement. In one construction, the pressurized gas is supplied through a chamber (48, 48a) between the plates through a set of shorter tubes (80, 80a) mounted within the first set of holes (42 42a) in the lower plate (38, 38a), and a vacuum is drawn from the upper side of the upper plate (46, 46a) through the holes (52, 52a) therein and through the passages (55, 55a) and the second set of holes (44, 44a).
