Abstract: A glass manufacturing apparatus can include an elongated engagement surface rotatable through a rotation angle between a scoring position and a cleaning position. The glass manufacturing apparatus can further include a scoring device to score the glass substrate when the elongated engagement surface is positioned in the scoring position. The glass manufacturing apparatus can further include a cleaning device to clean the elongated engagement surface when the elongated engagement surface is positioned in the cleaning position. In further embodiments, a method of scoring a glass substrate can include, after producing a score line while the elongated engagement surface is positioned in the scoring position, rotating the elongated engagement surface from the scoring position to a cleaning position. The method can further include cleaning the elongated engagement surface while the elongated engagement surface is positioned in the cleaning position.

Abstract: A method of separating a moving glass ribbon to form an individual sheet of glass is disclosed comprising a plurality of nosing members that move in a direction and at a speed that the moving glass ribbon is moving. The nosing members can be positioned independently of each other, and can be positioned adjacent to but not in contact with the ribbon during the scoring operation to restrict out-of-plane movement of the glass ribbon (movement substantially transverse to the draw direction of the ribbon) during the separation phase of the process.
