ABSTRACT:
A gravity sag bending mold of the outline type for bending glass sheets is provided with the following improvements: (1) A plurality of rod-like glass supporting members are affixed outwardly and slightly above the shaping surfaces of the bending mold to reduce glass slippage and mold marking. (2) The bending mold is comprised of a plurality of rigid shaping rail sections, each independently mounted so that the outline dimensions can be adjusted slightly. (3) The bending mold is tilted downwardly in the direction of travel a maximum of 5 degrees to reduce glass slippage.
