    摘要: Glass sheets are positioned on the shaping rail of an outline shaping mold for movement through a heating lehr and subsequent preliminary sag bending. The mold with the glass sheet supported thereon is then positioned between a pair of vertically aligned full surface pressing molds. The lower mold includes selected press surface areas that extend outside the perimeter of the outline mold. As the lower mold raises to lift the glass sheet off the outline mold, selected portions of the shaping rail move outwardly to allow the lower mold to pass through the outline mold. The glass sheet is then pressed between the upper and lower pressing molds.
