<p>PCT No. PCT/FI95/00584 Sec. 371 Date May 28, 1997 Sec. 102(e) Date May 28, 1997 PCT Filed Oct. 24, 1995 PCT Pub. No. WO96/12682 PCT Pub. Date May 2, 1996A method and an apparatus for bending and tempering of a glass sheet is disclosed. The means to be used in the method for supporting the glass sheet is a supporting device in two parts, wherein the first supporting device forms a substantially planar supporting surface for the margin of the glass sheet and the second supporting device forms, in a manner known as such, a supporting device for the margin of the glass sheet corresponding to the bending configuration. In the method, the first supporting device supports the glass sheet to maintain its planar configuration at the heating stage required for tempering, wherein the glass sheet is being heated to the tempering temperature. During heating, the glass sheet is further supported by a pressure difference imposed on the opposite surfaces of the glass sheet. After heating, the glass sheet is moved to the second supporting device to bend to the bending configuration determined by the second supporting device, followed by the tempering stage.</p> |
