The invention relates to a production line for curved panes, in which the panes of glass are heated, brought in a horizontal position into a curving station where they are taken over by curving tools, and then finally conveyed into a quenching station, the stages of quenching and of entry of the glass into the curving station being at different heights.

The invention relates to a production line for curved panes, in which the panes of glass are heated, brought in a horizontal position into a curving station where they are taken over by curving tools, and then finally conveyed into a quenching station, the stages of quenching and of entry of the glass into the curving station being at different heights. Defective glass sheets are removable from the production line intermediate the curving station and the quenching station by cracking with an atomized fluid jet and subsequent crushing.

Method and apparatus for shaping curved glass sheets

The invention relates to the precise positioning of sheets of glass on a conveyer, particularly in an installation for curving sheets of glass. Positioning the sheets of glass by means of a combination of actions, in whole or in part, comprising orientations, longitudinal centerings and transversal centerings.

Method of and apparatus for positioning of sheets of glass for curving

A process for bending glass plates into convex shape and, in particular, to their precise positioning with a view to that bending. The glass plates to be convexed are centered while a hot gas is blown under said plates in order to take up a part of the weight of the glass thanks to that blown gas. It makes possible a recentering of the glass plates without deterioration of said plates in spite of their friction on the rollers carrying them.

Method and apparatus for positioning of glass plates to bend them into a

Curving of glass sheets by application of said sheets against an upper curving form and possibly subsequently, after the deposit of said sheets onto a lower curving form, by depressing in accordance with said upper form is improved. After the taking up of a sheet of glass by the upper form, a current of hot gas is blown under the glass sheets in order to produce a pneumatic pressing. The process and opportunities enables the manufacture of curved glasses in accordance with complicated shapes and/or with an accentuated curvature but, nevertheless, with a surface free from defects.
