ABSTRACT:
A traveling vacuum pickup engages heat softened glass sheets in a transfer station and transfers them to one of two shaping stations positioned along opposing sides of a transfer station. After depositing the sheet within one of the shaping stations, the pickup return to the transfer station to receive the next heat softened sheet. The shaping stations may include pressing arrangements that shape successive sheets to different configurations. The vacuum pickup may include two sheet engaging surfaces positioned relative to each other such that as one engaging surface engages a glass sheet and transfers it to one of the shaping stations, the other engaging surface is being positioned within the transfer station to receive the next glass sheet.
