Abstract

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.
