Process and apparatus for heating glass sheets |
摘要 |
A device and a process for heating glass sheets in horizontal position, to bend them or temper them, by means of two series of resistors, the series being distributed on both sides of the path followed by the glass sheet and on a portion of the length of this path. Each resistor group is distributed in longitudinal zones or in crosswise subzones of various widths along the longitudinal zones, the power furnished to each longitudinal zone being regulated independently of the power furnished to the other longitudinal zones and being distributed in a controlled way between the crosswise zones and the longitudinal zones.
