ABSTRACT:
The invention relates to a method and a device for blow-moulding containers from preforms which are previously heated in the region of a heating section and consist of a thermoplastic material. The preforms are transferred to a blowing device following the heating thereof, in which they are shaped to form containers by the application of a blowing pressure inside blow moulds. Said blow moulds respectively consist of at least two blow mould segments. The preforms are transported together with the blow moulds at least along part of a peripheral path of a rotating blow wheel. A separating plane of the blow mould segments is positioned at least in an opened state of the blow station in a rotational direction of the blow wheel, facing forwards, with an angle of inclination in relation to the radial direction of the blow wheel. The blow station is positioned at least in two parts during a transfer process.
