Abstract

Each glass plate, brought to a high temperature, arrives flat on a conveyor by resting there by its lower face, is picked up by its lower face, is turned over to bring its initially lower face into the upper position, and is then placed on a bending form the profile of which it assumes. A device for accomplishing this process has a pivoting plate capable of turning the glass plate over, a bending form, optional pressing means, and a frame for conveying bent glass plates to a succeeding work station.
