  • Method for producing a hollow body provided with a stand ring by blow moulding
    Patent number: 4769206
    Abstract: In a blow mould firstly a convexly formed bottom is blown. An intermediate region lying between an axially displaceable bottom mould and the blow mould bears on mould portions which on introduction of the bottom mould are pivoted back for turning back the bottom region to form a stand ring and release the path for the bottom mould which is finally positioned on the blow mould so that a closed mould cavity is formed on which the transformed bottom region can be reliably applied by blow pressure.
