Abstract
The invention relates to an apparatus for bending glass panels. An upper tier of successive mould carriages (9) defines a number of heating stations, the final one being an actual bending station (4b). A lower tier of successive mould carriages (9) defines a number of cooling stations (5, 6, 7), which are located underneath the heating stations. The mould carriages have an open-structured or otherwise highly heat transmitting floor (10). A pre-bending station (4a) preceding the bending station (4b) and at least the final preheating station (3b) have a floor (15), on top of which are radiation heating elements (16) positioned below a floor (10) of the carriage (9) for speeding up the heating of a bottom glass panel for preventing it from falling behind from the heating of a top glass panel.
Claims7
An apparatus for bending glass panels, said apparatus comprising
- an upper tier of successive mould carriages (9), having a front or back wall (11) thereof separating successive preheating stations (2, 3) and one or more successive bending stations (4a, 4b) from each other, said mould carriages (9) being adapted to be intermittently movable towards the bending station (4b);
- a lower tier of successive mould carriages (9), having a front or back wall (11) thereof separating successive cooling stations (5, 6, 7) from each other, said mould carriages being (9) being adapted to be intermittently movable in a direction opposite to the moving direction of the upper tier carriages;
- a number of bending moulds (12) supported by the mould carriages (9);
- radiation heating elements (13, 14) in the ceiling of the preheating stations at least in some (3) of the preheating stations;
- radiation heating elements (14) in the ceiling of one or more bending stations (4a, 4b);
- an intermediate floor (15) which separates the pre-bending station (4a) upstream of the bending station (4b) and/or at least the last preheating station (3b) from a station (5) therebelow;
- a lift mechanism (20) which constitutes a floor for the bending stations (4b) for lowering the mould carriages (9) from the upper tier to the lower tier together with bent glass panels;
- the mould carriages (9) being provided with an open-structured or otherwise highly heat transmitting floor (10), characterized in that on top of the intermediate floor (15) are radiation heating elements (16) positioned below the level defined by a floor (10) of the mould carriage (9).
