Abstract
A glass sheet processing system including topside transfer apparatus (12) for transferring glass sheets during processing. The transfer apparatus (12) supports glass sheets at a downwardly facing surface (36) by a vacuum drawn through a first set of holes (38) in the surface and by pressurized gas supplied through a second set of holes (40) in the surface. The topside transfer apparatus (12) has particular utility when utilized in a glass sheet forming system (10, 10') to transfer a heated glass sheet from a heating conveyor to a curved mold for forming. In addition, the topside handling apparatus has other uses such as conveying glass sheets during heating prior to processing, supporting a heated glass sheet on a deformable platen for forming, and loading a glass sheet onto a conveyor for processing.
