<p>A gravity bending mould for bending glass sheets, the gravity bending mould comprising a peripheral shaping rail, the peripheral shaping rail having at least one end section, and at least one auxiliary rail mounted on the peripheral shaping rail, the or each auxiliary rail bein g respectively mounted adjacent to at least a portion of a respective end section by at least one mount that is adapted to permit relative vertical movement of the auxiliary rail with respect to the resp ective end section, a tripping mechanism for selectively and temporarily disposing the auxiliary rail in a raised position with respect to the respective end section, and a latch mechanism connected to the tripping mechanism, the latch mechanism being adap ted to be engaged by an external actuator to cause relative vertical movement of the auxiliary rail with respect to the respective end section, by operation of the tripping mechanism, so that the auxiliary rail is subsequently disposed in a lowered position with respect to the respective end section. There is also provided a method of bending glass sheets using such a mould.</p> |
