ABSTRACT:
A glass sheet has marginal zones thereof removed by (a) subjecting the marginal zones to a heating flame, and (b) raising the glass sheet (during or after the flame heating) while restraining upward travel of the marginal zones. The lifting is performed by suction cups which depend from a movable carriage, and the restraining is performed by removing members having inclined lower faces disposed over the marginal zones. The removing members are connected to rods which carry the suction cups, the rods and removing members being relatively movable upwardly and downwardly. The rods are horizontally adjustable relative to the carriage for repositioning the suction cups and removing members relative to a glass sheet.
