BENDING GLASS SHEETS TO A TAPERED LINE OF BEND

摘要

BENDING GLASS SHEETS TO A TAPERED LINE OF BEND Glass sheets are bent along a line which is sharply creased at one end and gently curved at the opposite end. Localized heating along the line is provided by an electrically heated ribbon mounted above the glass so as to maintain a constant spacing between the glass and the ribbon at one end of the line, while the spacing at the other end of the line gradually increases as bending progresses.
