Cutting and grinding apparatus for a glass sheet edge

A cutting and grinding apparatus for a glass sheet edge, comprising a cutting machine (3) for cutting a contour, a crushing machine (4) for removing an edge zone outside the cut contour, a grinding machine (5) for grinding the edges of a glass sheet blank, and a conveyor (6, 7, 8) for carrying a glass sheet blank to each of the above-mentioned machines for performing their respective cutting, edge-removing and grinding operations, said grinding machine (5) comprising two rotatable glass-supporting tables (10) and two grinding heads (12), positioned relative to tables (10) in a manner that the edges of glass sheets (9) lying on the tables can each be brought into a contact with its own respective grindstone (13), characterized in that the apparatus further includes displacement guides (11) for shifting tables (10) aside from a transfer line (6) included in said conveyor (6, 7, 8), as well as a displacement mechanism (15) for tables (10), which is on the one hand controlled to carry out a shifting movement between transfer line (6) and grinding head (12) and, on the other hand, an advancing movement during a grinding operation for maintaining the edge of glass sheet (9) in contact with grindstone (13) during the rotation of a glass sheet having a shape other than circular.
