THE PRESENT INVENTION RELATES TO A PROCESS FOR THE MANUFACTURE BY THE FLOAT METHOD OF GLASS SHEETS, ACCORDING TO WHICH MOLTEN GLASS IS POURED ONTO A LIQUID SUPPORT (2) WHICH IS DENSER THAN THE GLASS AND THEN THE GLASS STRIP WHICH IS FORMED IS DRAWN AND IS ACCOMPANIED IN ITS MOVEMENT USING CONTINUOUS AND FLEXIBLE GUIDING ELEMENTS (5) MADE OF A SOLID MATERIAL CAPABLE OF ADHERING TO THE MOLTEN GLASS, THESE ELEMENTS(5) BEING BROUGHT INTO CONTACT WITH THE SIDE EDGES OF THE STRIP, THE PRODUCT (P) OF THE VALUE (S) OF THE SPEED OF THE STRIP AND OF THE VALUE (T) OF ITS FINAL THICKNESS BEING LESS THAN 2.5 x 10-4 M2, S-2. THIS PROCESS MAKES IT POSSIBLE TO OBTAIN THIN GLASS SHEETS EXHIBITING A CONSTANT THICKNESS AND A SATISFACTORY OPTICAL QUALITY. (FIG.1)
