Abstract:
A machine for moulding hollow glass items comprises a basement (2null) supporting a plurality of modules (4null) placed side by side, having first and second devices (13, 14) supplying cooling air for parison and blow moulds. A first (VI, 16-22) and a second (V2, 26-31) air supply arrangement supply independently the first and second supply devices (13, 14). Both supply air flows (F1, 15, F2, 25, 25null) get independently through each module (4null) through the basement (2null) and within the module.
