| 摘要 |
The invention describes a machine typically comprising two or four carriages with associated mould/counter-mould (S1, S2) units movable along perpendicular axes, with one mould and counter-mould unit which cyclically is loaded with parisons and is displaced for the container blow-moulding operation, while the other mould and counter-mould unit is prepared for unloading the containers formed during the previous cycle and then insertion into the parison supply station. Each mould/counter-mould unit has, associated with it, a blowing station which follows the unit during the displacement on the associated primary carriage (3), but not during the movement on the secondary carriages (10) for insertion into and extraction from the station with the extrusion head. A centralized pair of grippers is envisaged on the side of each primary carriage and in alignment with the extrusion head and performs extraction of the bottles formed by each mould and counter-mould unit and transfer of the said bottles into the following finishing stations and finally onto the single product exit way.
