    摘要: In an apparatus for producing hollow bodies from thermoplastic material in large numbers a plurality of stations in which the blanks are successively subjected to various treatment steps are arranged at horizontal spacings around the peripheral surface of a vertical, substantially cylindrical housing of an operating unit of the apparatus. The blanks to be treated are passed downwardly through the operating unit and a first one of the treatment stations therein to the next station therein. Arranged within the operating unit is a cam drum which rotates about a vertical axis and which has cams adapted to actuate tools for treating the blanks in at least some of the treatment stations. Two or more such operating units may be connected in succession for carrying out successive treatment operations on the blanks.

    摘要: 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.
