A method and apparatus is described, with which individual rectangular glass panes of thickness between 0.03 mm and 2 mm can be cut from a glass band ( ) drawn vertically from a hot forming device ( ) in an in-line process with reduced rejects and reduced waste. The method provides that the glass band ( ) drawn vertically downward through a vertical zone is cooled below a lower cooling point of the glass and subsequently is deflected through a bending zone ( ) with a bending radius between 0.1 m and 4 m into a horizontal zone ( ) in which it is horizontally oriented. The vertical alignment of the glass band ( ) in the vertical zone ( ) is continuously monitored. At least one cutting process is performed on the horizontally oriented glass band ( ) in the horizontal zone ( ). The device ( ) for monitoring the vertical alignment of the glass band ( ) includes at least three sensors ( &prime;) that detect the glass edges These sensors can be mechanical rollers.
