A device for pressing and bending glass panes comprises an upper, solid-faced bending mold and a lower frame-shaped mold. The lower frame mold is mounted horizontally traversable and serves at the same time as a support ring for transferring the bent glass pane into a cooling station. The frame-shaped mold is provided with an electrical heating resistor. In addition, a temperature sensor is disposed in the frame-shaped mold. The temperature of the frame-shaped mold can be regulated to a predetermined temperature by way of a power regulator, which is governed by the temperature sensor.

Bending press for the production of curved glass panes

A production installation for the contact toughening of glass sheets comprises a horizontal furnace for heating the glass sheets, a press containing two liquid-cooled pressing plates, a feed apparatus for transferring the heated glass sheets into the press and a removal apparatus for removing the toughened glass sheets out of the press. To the lower pressing plate, a solids-transmitted sound pick-up is coupled which, if a glass sheet breaks in the press, supplies an electrical signal. From this signal, after suitable processing of the signal, the control device is triggered, and as a result thereof interrupts the process sequence.

Method and apparatus for pressing and contact toughening glass sheets

A bending furnace for glazings comprises several heating cells, a station for bending by pressing, at least one cooling cell and a system for intermittent transport of glazings. The glazings are laid on bending rings (2), mounted on mobile carriages (3), coupled to one another in a train. The train is pulled by a pulling machine installed at the end of the furnace and outside the latter. The point of application of the pulling machine which moves carriages (3) and the length of the travel of this pulling machine are controlled as a function of the temperature to take into account the variation of length of the train. The precise positioning of the carriage in the pressing station is obtained by a detector (27) joined to pivoting stops (28, 36).

Bending furnace for glazings

A process for bending a glass sheet, in particular one for motor vehicles, with curved areas having small radii of curvature. The bending device used is a bending press having a male type mold and a female type mold. The female type mold consists of at least two mold parts hinged together. After part of the glass sheet heated to bending temperature has been received by the bending press, at least one swivelling mold part of the female type mold is swivelled around the swivel axis, against the male type mold. An adjustable electric motor serves as the drive motor to move the swivelling mold parts. The angular velocity of the swivel action of the swivelling mold parts during the bending process is adjusted as a function of the temperature of the glass sheet and the desired degree of deformation.

Process and apparatus for manufacturing a curved sheet of glass

The panel includes two thermally prestressed silicate glass plates with metalized edges to which are solder-sealed lead bars which, in turn, are solder-sealed to a tubular frame. An outer protection frame covers the plate edges. Spacer posts and elements support the plates against pressure upon evacuation. The absorber proper is centrally disposed in the evacuated chamber.
