Zusammenfassung:A device (100) for producing three-dimensional hollow bodies by blow-moulding, comprising an extrusion group (1), consisting of an extrusion or coextrusion head (6), for producing a tubular parison (7), a manipulator (9) to position the parison (7) into a cavity (10) of a blow-mould (11), and a blowpin or needle (22) to blow the parison within the mould (11); the mould (11) can move horizontally and vertically and provides a 'book-style' opening and closure system.
