Abstract
A heat softened glass sheet is lifted within a heating furnace by a vacuum pickup and moved to a shaping station adjacent the furnace where it is deposited on an aligning frame. The location of the sheet is identified and the frame is moved to position the supported glass sheet at a predetermined location between a pair of vertically aligned upper and lower full surface press faces. A shuttle frame which moves the vacuum pickup has integral vacuum passageways so that vacuum for the pickup can be drawn through the shuttle frame.
