| 摘要 |
<p>The invention relates to a heating apparatus for a glass-sheet bending station, said apparatus comprising an array of elongated heating resistance elements (3), positioned side by side to develop a resistance field covering the area of a glass sheet (4) to be bent, as well as a control mechanism (1, 2) for switching resistance elements (3) on and off. Separate, independently controlled resistance elements (3) are placed in resistance element fields successive in the longitudinal direction of said resistance elements and control mechanism (1, 2) is adapted in accordance with a selected program to switch on resistances (3) of successive resistance element fields in such a stagger that the resistances switched on in successive fields produce at least one heating line whose direction is different from that of the resistance elements. <IMAGE></p> |
