摘要：The invention relates to a method for producing blow-moulded hollow bodies.Flat preforms (1, 1') are produced during the working cycle of a blow-mouldinginstallation, said preforms emerging from wide-slit nozzles (2), and being connected,while still in the thermoplasticised state in the blow-moulding installation, along a pinch-off weld formed by the closing of the blow-mould (3), and expanded to form a hollowbody (4). So that the flat preforms assume a reproducible position both in relation to therespective blow-moulding half (10) and to each other, a plurality of measures accordingto the invention are carried out alone or as a group. The synchronism of the preformsemerging from the wide-slit nozzles is monitored. If there are variations in thesynchronism behaviour, the flow resistance is modified in order to correct thesynchronism by heating the flow channels differently and/or by actuating a throttleelement (17) acting on one of the partial flows, or the transport power of a plasticisingunit (5) is adapted.
