An apparatus for bending and tempering glass panels includes a number of ring moulds for supporting and conveying glass panels; a number of preheating sections for heating glass panels to a bending temperature; at least one prebending section for sagging a glass panel gravitationally; a bending section provided with a hoistable and descendable press mould; and a quenching section for tempering a bent glass panel. The bending section is provided with a hoistable and descendable mould supporting frame for supporting the mould from below during a press-bending operation. The supporting frame is mounted on a mobile cassette wagon which constitutes a replaceable floor for the bending section.

Apparatus for bending and tempering glass panels

The invention relates to an apparatus for bending glass panels. The upper tier of successive mould carriers defines a number of heating sections, the last one of which is an actual bending section. The lower tier of successive mould carriers defines a number of cooling sections, which are located below the heating sections. The mould carriers are provided with an open-structured or otherwise highly heat transmissive bottom. Underneath bending sections, effecting gravitational bending on an upper mould carrier track, lie cooling sections, each of which is individually provided with controlled cooling air circulation by means of cooling air exhaust fans. Following the sections performing the controlled cooling or annealing, the mould carriers are adapted to be conveyed along a lower mould carrier track nonstop under a plurality of preheating sections by a single passage.

Apparatus for bending glass panels

The invention relates to an apparatus for bending glass panels. An upper tier of successive mould carriages () defines a number of heating stations, the final one being an actual bending station (). A lower tier of successive mould carriages () defines a number of cooling stations (), which are located underneath the heating stations. The mould carriages have an open-structured or otherwise highly heat transmitting floor (). A pre-bending station () preceding the bending station () and at least the final preheating station () have a floor (), on top of which are radiation heating elements () positioned below a floor () of the carriage () for speeding up the heating of a bottom glass panel for preventing it from falling behind from the heating of a top glass panel.
