Abstract

An installation for the bending of glazings (6) includes a continuous furnace (1), a station for bending by pressing (10) with a lower shape (11) and a suction shape (15), a plate-suction device (50) that can be displaced longitudinally to transport the glazings (6) from the roller conveyor (7) to the station for bending by pressing (10), and an annular frame (35) that can be displaced horizontally to transport the bent glazings (61) to the cooling station (4). Lower shape (11) is mounted stationary lengthwise and a transfer station (30) is provided between the station for bending by pressing (10) and the cooling station (4). The upper shape can be displaced between the station for bending by pressing (10) and the transfer station (30), in synchronism with the plate-suction device (50).

Dependent claims

Installation for the bend of glazings, comprising:

a continuous furnace for heating glazings to a bending temperature;
a conveyor for conveying glazings through the furnace;
means, including a lower bending shape, for defining at least one bending station in the furnace;
means for defining a transfer station in the furnace;
plate suction means in the furnace and mounted for displacement to transport glazings from the conveyor to the lower bending shape of the at least one bending station;
an upper suction shape, in the furnace, for bending a glazing in the at least one bending station and mounted for displacement to transport glazings from the at least one bending station to the transfer station in synchronism with movement of the plate suction means, so that the displacement to transport glazings of said plate suction means is performed simultaneously with the displacement to transport glazings of said upper suction shape;
and
an annular frame movable between said transfer station, where a glazing is transferred thereto from the upper suction shape, and a cooling station outside of said furnace.
