ABSTRACT:
A glass sheet positioning system to correctly position a heat softened glass sheet between a pair of vertically aligned upper and lower full surface press faces. A video camera identifies a reference point on an edge of a glass sheet while supported on a frame between the press faces. A programmable computer and controller determine the distance between the reference point and a predetermined set point corresponding to the proper location between the press faces. The controller signals a drive that moves the frame with the glass sheet thereon to the proper predetermined position.
