ABSTRACT:
A vacuum press for shaping both left and right hand sidelights, quarterlights and the like which are asymmetric in bend and mirror images of each other. The shaping surfaces of the mold have certain overlapping shaping areas that shape both the left and right hand windows and additional shaping areas bend only the left or right hand window. A timing sequence positions each glass sheet to be bent at the correct location between the shaping surface of the molds.
