Abstract
A travelling vacuum pickup is used to transfer heat softened glass sheets from a heating furnace to between a pair of vertically alignment pressing molds. The downstream movement of the pickup is synchronized with the downstream movement of the glass sheets to be engaged so that there is no relative downstream movement therebetween as the pickup lifts and engages the glass sheet.
