Abstract: The invention relates to a method for shaping a glass sheet having a reflective low emissivity coating thereon comprising the steps: (i) positioning the coated glass sheet at a furnace entrance; (ii) conveying the coated glass sheet through the furnace to heat the glass sheet to a temperature suitable for shaping; (iii) transferring the coated glass sheet on to a first bending tool for supporting the coated glass sheet, the first bending tool having a fixed wall and first, second and third movable walls; (iv) moving at least one of the first, second and third movable walls to adjust the position of the coated glass sheet on the first bending tool ring from a first position to a second position; and (v) shaping the coated glass sheet between the first bending tool and a die. Apparatus for carrying out the method is also disclosed.

Abstract: An apparatus for edge grinding a glazing comprising a grinding wheel, rotatable about an axis, a groove in a circumference of the wheel and first and second orifices arranged on first and second sides of the plane of the groove, which form first and second jets of coolant directed substantially into the groove on first and second trajectories not in the plane of the groove. A corresponding process for edge grinding causes fewer sharp portions and fewer small fractures in the glazing edge than the prior art. A glazing manufactured by the apparatus or the process has higher edge strength than the prior art.

Abstract: Disclosed is a process for producing a laminated glass, which can prevent the formation of air bubbles in a peripheral part of the laminated glass. In the process, a substance (17) which contains a polyalkylene glycol in the structure thereof is applied on a peripheral edge surface of a laminate (14) which comprises at least two glass plates (11, 13) and a polyvinyl butyral film (12) intercalated between the glass plates, and the laminate (14) is subsequently heated and pressurized in an autoclave (21).
