摘要

An arrangement for producing thin sheets of glass, especially sheets which are less than 3 mm thick, comprises a melting bath, a homogenising system, a supply and a drawing tank. The drawing tank has a nozzle system with at least one nozzle slot. The tank (7') has at least two sections of different cross-section, which are dimensioned so the pressure drop at each point on the nozzle (8) is constant.
