MANUFACTURE OF GLASS-CERAMIC PLATES HAVING OPENING(S) OF BENT PERIMETER, BENT GLASS-CERAMIC PLATES

摘要

The present invention relates to: - a method of bending the perimeter of at least one opening (2) provided in a glass-ceramic precursor plate (1), said perimeter describing a closed curve without sharp angles; - a method of manufacturing a glass-ceramic plate (10', 10") in which at least one opening (2) is provided, whose perimeter describing a closed curve without sharp angles is bent; - novel glass-ceramic plates (10', 10"), obtainable by implementing said manufacturing methods.
