| Zusammenfassung: | A method of, and apparatus for, separating a sheet of glass along a score line on the sheet. The method comprises flexing the glass at the score line along an axis of flexure on the support to pre-stress the glass to a level below the critical stress level, and initiating a break at one end of the score line. The apparatus comprises a support for the sheet, the support defining an axis of flexure for alignment with the score line, at least one movable pressure member spaced above and on one side of the score line, a press head to move the pressure member into contact with the sheet of glass to pre-stress the sheet at the score line, and a break initiator at one end of the score line. |
