20120067861 | NOZZLE HOUSING ASSEMBLY - A nozzle housing assembly, which is used in a convection heating furnace for a heat treatable glass sheet. The nozzle housing assembly comprises an elongated enclosure, at least one elongated heating resistance in the enclosure for heating convection air, and orifices in a bottom surface of the enclosure for blasting heated convection air against the glass sheet. The enclosure is divided with a flow-throttling partition into a top supply duct and a bottom nozzle box, the heating resistances being housed in the latter. Flow-throttling openings present in the partition are positioned to comply with the location and shape of the heating resistances. | 03-22-2012 |
20110219822 | APPARATUS FOR HEATING GLASS SHEETS FOR TEMPERING - An apparatus for heating glass sheets for tempering. The apparatus including a heating furnace having a longitudinal direction and a lateral direction, a conveyor in the furnace for carrying glass sheets in the longitudinal furnace direction, and an arrangement for circulating and heating convection air. The arrangement includes nozzle enclosures provided with jet orifices for blasting heated convection air towards the conveyor. The nozzle enclosures lengthwise of the furnace are disposed at an acute angle relative to the glass traveling direction. The angle is at least 2 degrees, preferably 2-10 degrees, most preferably about 3-5 degrees. | 09-15-2011 |
20110167871 | METHOD AND APPARATUS FOR SUPPORTING AND HEATING GLASS SHEETS ON A HOT GAS CUSHION - A method and apparatus for supporting and heating glass sheets for tempering or bending on a hot gas cushion. One edge of the glass is supported on transport rollers and the rotation axes of the rollers are transverse relative to the plane of the glass. The glass sheet is supported by means of gas pressure on a planar surface which has an angle of inclination of 2-20° relative to horizontal plane. The angle of inclination is sloping towards that edge of the glass which is supported by the transport rollers. Gas is expelled through the planar surface by way of gas outlet slots or holes. As the glass is moving, a gas is drawn or blown by fans from a certain part of the glass through the planar surface more than from the rest of the area by adjusting the rotating speed of the fans or by changing the suction pressure or delivery side pressure of the fans. | 07-14-2011 |
20100180637 | METHOD AND APPARATUS FOR BENDING AND TEMPERING A GLASS PANEL - The invention relates to a method and apparatus for bending a glass panel. A heated flat glass panel is fed from a furnace onto a bending conveyor while the bending conveyor is in a straight configuration. The bending conveyor and the glass panel are arched to a desired curvature while the glass panel travels along the bending conveyor. An interpolating position-setting for the tempering conveyor's upstream end with respect to the tempering conveyor's bending radius is performed in such a way that a certain point at the tempering conveyor's upstream end coincides with a certain point at the bending conveyor's stationary downstream end. This position-setting is performed by moving the tempering conveyor in vertical and horizontal directions and by pivoting the tempering conveyor so as to change an angle between its center line of curvature and a vertical line. | 07-22-2010 |
