Abstract
An apparatus (10) is disclosed for bending and tempering a heated glass sheet (12) between first and second bending platens (14,32). Platens (14,32) include actuators (22,36) respectively, for deforming the platens (14,32) to form the desired bend in the glass sheet (12) therebetween the platens (14,32). A vertical guide (16) constrained at both ends (18,20) controls vertical movement of the first platen (14) and a central actuator (42) constrained at both ends (44,46) controls vertical movement of the second platen (32). The vertical guide (16) and central actuator (42) cooperably operate to control the specific geometric orientation of the bend on the glass sheet (12).
