Abstract
Apparatus (16) and a method for roll bending heated glass sheets includes a pair of sets of bending rolls (40) and a support and drive mechanisms (44) that supports and rotatively drives the bending rolls at progressively increasing inclinations within a heating chamber (32) of a roll bending station (18) to provide engagement and bending at opposite lateral sides of a conveyed glass sheet. The bending rolls (44) are positioned in their progressively inclined inclinations by cooperation of an elongated connector (60) and clamps (64) for providing securement to curved support ribs (48) of an associated frame at the adjacent lateral side of the roll bending station housing.
