A plurality of glass plates are positioned under upper units capable of bending and/or transferring those plates, the pick up and release of each plate being independent of each other. The plates are bent either on the upper station, or on a lower unit onto which they are released from the upper station. The plates are subsequently subjected to tempering. Mass production of tempered glass plates at both high quality and high output levels is thus achieved.

High-capacity process for bending glass plates into convex shape

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.

Apparatus for bending glass plates into convex shape

A method and apparatus for the transfer of pane objects such as glass comprises a conveyor along which the pane is accelerated past the downstream end of the conveyor. As the pane leaves the conveyor, it is received by a device which is aligned substantially parallel to the trajectory of the path of the pane. The device receives the pane, and transfers it to the next work station.

Process and apparatus for the transfer of glass panes from a conveyor to

A device and process for transferring glass panes for bending comprise the raising of glass panes with a gaseous flow until they meet with an upper conveyor, maintaining contact with that conveyor and simultaneously shifting them along that conveyor, then bringing them down anew on a bending form upon which they subside.
