ABSTRACT:
A glass sheet is press bent between a pair of bending molds of complementary shape provided with covers using burning gas source means that supplies heat by directing burning gas flames toward the bottom edge of a glass sheet. The burning gas source means is constructed and arranged to be directed toward the path taken by the glass sheet when the latter moves into a shaping position with the press bending molds retracted and to pivot away from the mold covers when the press bending molds engage the glass sheet including its bottom edge during the shaping of the sheet. Preferably, the burning gas source means has a shape that conforms with the shape of the bottom edge of the glass sheet undergoing press bending and has an upwardly directed downstream portion to provide clearance as the glass sheet moves into said shaping position in a direction such that a recessed lower edge portion thereof is the leading edge of the glass sheet during its path of movement into the shaping station.
