<p>An apparatus for making containers (13) such as bottles, pots or any other hollow body by heat treating then blow-moulding plastic parisons (1). The apparatus comprises at least two book moulds (41, 44) arranged around the edge of a carousel. Each mould includes at least two mould cavities. The apparatus further comprises a device for heat treating the parisons, in which the pitch (P1) between the longitudinal axes of two consecutive parisons is smaller than the pitch (P2) between the longitudinal axes of two adjacent cavities in one mould, as well as means (5A) for varying the parison pitch between a conveyor and a mould. Said pitch varying means (5A) comprise at least two adjacent movable members (52) that can be arranged at the first pitch (P1) when they are facing the conveyor, and at the second pitch (P2) when they are facing the means (5B) for transferring the parisons to the moulds.</p> |
