PROCESS FOR MANUFACTURING FOLDED VITROCERAMIC PLATES, BY FOLDING PRECURSOR AND VITROCERAMIC GLASS PLATES AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

P The folding of the glass-ceramic precursor plates is carried out in a heated space 2, the temperature of which is 10 to 50 ° C. higher than the processing temperature of the glass-ceramic precursor glass of the plate 1 to be folded, the plate 1 being brought here in mechanical contact with a shaped body serving as a workpiece support 3 which is maintained at the temperature of the space 2 and which defines geometric contours corresponding to the folding geometry, the folding zone 1c undergoing additional heating using heat sources 5 such as burners. Application: For example, the folding of facade panes for fireplaces and cooking surfaces. /P
