20110094267 | METHODS OF PRODUCING GLASS SHEETS - A method of producing glass sheets includes the step of fusion drawing a glass ribbon along a draw direction into a viscous zone downstream from a root of a forming wedge. The method further includes the step of drawing the glass ribbon into a setting zone downstream from the viscous zone, wherein the glass ribbon is set from a viscous state to an elastic state. The method further includes the steps of drawing the glass ribbon into an elastic zone downstream from the setting zone and stabilizing a region of the glass ribbon in the elastic zone along a width of the glass ribbon extending transverse with respect to the draw direction. A predetermined pressure differential between a first side and a second side of the glass ribbon is used to create the stabilized region. The method further includes the step of cutting a glass sheet from the glass ribbon, wherein the stabilized region inhibits shape instabilities from propagating upstream through the glass ribbon to the setting zone. | 04-28-2011 |
20110167873 | ACTIVE EDGE ROLL CONTROL IN A GLASS DRAWING PROCESS - An apparatus for drawing a glass ribbon including an edge roll assembly that contacts the glass ribbon with a force that is dynamically altered by an actuator electrically coupled to a sensor that measures the force applied against the ribbon. Dynamic, or real-time, variation of the edge roll force minimizes stress variability in the glass ribbon and improves ribbon shape control. | 07-14-2011 |
20130118206 | GLASS-SUBSTRATE MANUFACTURING METHOD AND GLASS-SUBSTRATE MANUFACTURING DEVICE - An objective of the invention is to provide a glass-substrate manufacturing method that is capable of increasing the amount of production of glass substrates and improving warpage quality. A glass-substrate manufacturing method according to an aspect of the invention is a method for manufacturing glass substrates by employing a down-draw process. In down-draw processing, a molten glass is made to overflow from a forming member and formed into a sheet glass and the sheet glass is then cooled while being drawn in a downward-flow direction. In this glass-substrate manufacturing method, after the sheet glass has separated from the forming member and when the temperature of the sheet glass is within a temperature region ranging from a temperature higher than the softening point to a temperature near the annealing point, the sheet glass is cooled by maintaining the viscosity of side sections of the sheet glass within a range of 10 | 05-16-2013 |
