A mould cooling device is based on air which runs through an annular recess (17) and axial internal conducts (19, 21) with an upper and a lower portion so that the cooling process can start from the middle axial development of the mould; whenever a different kind of bottle is to be manufactured, height adjusting means (34, 38) of air compressed chamber (9, 10) allow this chamber to co-operate with a plurality of different moulds (1). |
