A plant for making containers of thermoplastic material in continuous cycle comprises: a rotary moulding machine (1) configured to make parisons (2) of thermoplastic material having a body (3) with a closed bottom and a neck (4) which defines an opening; an oven (5) for heating the parisons (2), connected to the moulding machine (1) and equipped with heating means (6) operating on the body (3) of the parisons (2); a rotary blow-moulding machine (7) configured to receive the parisons (2) heated in the oven (5) and to blow-mould them in moulds (8) to make the containers; and a management unit (9) for the plant (10), configured to switch off the oven (5) heating means (6) during a shutdown period of the blow-moulding machine (7) but without interrupting the operation of the moulding machine (1), so as to enable the parisons (2) located in the oven (5) to cool down during their transit through the oven (5). |
