ABSTRACT:
In a mold for press bending glass sheets hung from glass-gripping tongs in which the shaping surfaces have notches along their top edges to provide clearance for the tongs, kinking of the portions of the glass adjacent to the notches during the bending operation is inhibited by providing rigidly mounted tong stop means aligned with the notches so as to force the tongs into a predetermined displacement when the bending molds close.
