Abstract
Apparatus for bending glass plates provides a conveyor of serverable sections, each of which feeds glass plates to separate stations for bending the glass plates, the glass plates having first passed through a reheating furnace. The stations for bending or transfer employ a common upper unit, which is provided with a plurality of means for retaining the glass by aspiration under a vacuum. Each means for retaining the glass plate, and vacuum means associated therewith, is operable independently, such that the glass plates can be aspirated and released at each station independently of the actions of the remaining stations. After having been bent or shaped either on the upper retaining means, or lower bending units provided thereunder, the glass plates may be subjected to temper. Mass production of bent or shaped, and tempered, glass plates, with high, reproducible quality, and varying requirements, is made possible through such a system.
