Abstract A horizontal press bending arrangement for press bending heat softened glass sheets during transfer into a shaping station. The glass sheet is conveyed through a roller hearth or gaseous support hearth type furnace to heat the sheet to its heat deformable temperature. The sheet is then transferred beneath a vacuum/pressure pick-up to support the glass sheet in non-engaging contact therewith. The sheet is next deposited on a lower mold. The vacuum/pressure pick-up thereafter splits in two and moves out of the shaping station to allow the sheet to be shaped between a pair of vertically aligned shaping molds. After shaping the shaped sheet is removed for further processing, e.g., tempering.
