Abstract
The corners of a sheet of glass travelling in a longitudinal direction are ground by a corner bevelling assembly having a fixed frame; a movable frame; a grinding wheel; a supporting arm supporting the grinding wheel and fitted to the movable frame; and an actuating device interposed between the fixed frame and the movable frame, and having a first powered guide-slide assembly for moving the movable frame in a direction parallel to a longitudinal travelling direction of the sheet, and a second powered guide-slide assembly for moving the movable frame with respect to the fixed frame in a transverse direction perpendicular to the longitudinal direction; the corner bevelling assembly also having a reference locator which, in use, is positioned against a longitudinal lateral surface, parallel to the longitudinal direction, of the sheet; a relative-motion assembly for enabling movement, parallel to the transverse direction, of the reference locator with respect to the supporting arm; and a device for detecting the position of the reference locator with respect to the supporting arm.
