Abstract
A curving furnace has at least one curving station, of which the walls are equipped with resistors. The series of upper resistors are subdivided into one or more axial zones in which the resistors are oriented parallel to the height of the glass sheets, and into one or more transverse zones in which the resistors are oriented perpendicularly. The heating power of a given zone is regulated independently of the heating powers associated with the other zones.
