Abstract:
A method of manufacturing hollow bodies in a multi-cavity blow molding machine having an extrusion station, a calibration station spaced from the extrusion station and located parallel thereto, and a blow mold, the method comprising the steps of:inserting, into spaced molding halves of the blow mold, plastic hose-shaped blanks at the extrusion station and closing the blow mold;displacing the closed blow mold from the extrusion station to the calibration station;inserting, at the calibration station, blow mandrels into respective cavities of the closed blow mold;lifting, after expiration of a predetermined blow time, the blow mandrels, together with the blown hollow bodies, to an intermediate position and removing the blown hollow bodies from the blow mandrels;lifting the blow mandrels to an initial position thereof; anddisplacing the blow mold from the calibration station to the extrusion station;wherein both the steps of displacing the blow mold from the extrusion station to the calibration station and the step of displacing of the blow mold from the calibration station to the extrusion station include displacing the blow mold at right angle to a connection line of arranged side-by-side cavities of the blow mold.
