Abstract
A device and method are disclosed for the production of hollow bodies, especially plastic bottles, wherein a section of a plastic flexible hose is placed in a cavity of a blow mould by an extruder head according to a predefined clocked pulse. The plastic flexible hose is inflated inside the blow mould by a blow mandrel by overpressure according to the blow mould cavity. The manufactured inflated hollow body is subsequently removed from the mould. The plastic hose can be continually held on opposite sides of the blow mould arrangement during the entire extrusion and blow cycle.
