Title: Glass plate bending procedure

Abstract: Glass plates are re-shaped and tempered more accurately and with fewer rejects by horizontally passing vertically grasped plates into the heating oven to avoid problems inherent in the prior operation of passing said plates vertically downwardly into the heating oven. The plates are then heated to the softening temperature during horizontal movement through the heating oven and are then passed vertically upwardly to the re-shaping station.
