Abstract

An apparatus for separating pre-scribed glass shapes 10 from a glass sheet 12 includes a conveyor 22 for transporting the glass sheet parallel to its edges 14 with the margins 18 of the sheet accessible from both sides of the sheet. A pair of glass-cracking devices 24 are located substantially directly opposite one another on opposite sides of the conveyor respectively. Each glass-cracking devices 24 is arranged to bear repetitively on opposite sides of the respective margin 18 as the sheet is conveyed past thereby to break the sheet progressively along its margins to cause the glass sheet to fracture along scribe lines 16 defining the glass shapes. Each glass-cracking devices may comprise a pair of jaws which open and close on the respective margin or a pair of toothed wheels between which the margin passes.
