Abstract:
1. An apparatus for producing a hollow body, of thermoplastic, comprising: a lower machine part that has at least two blow molds each provided with a cavity, and beamlike upper machine part, disposed above the lower machine part, on which upper part a number of blowing and calibration mandrels corresponding to the number of blow molds is disposed, each being associated with one blow mold and being jointly feedable toward the blow molds axially and being movable with their calibration region into an orifice of the cavities until an annular shoulder of the blowing and calibration mandrels comes into contact with a counterpart face of the blow molds, the blowing and calibration mandrels being retained in the upper machine part axially freely movably within predeterminable limits, and upon feeding of the blowing and calibration mandrels toward the blow molds, the blowing and calibration mandrels being automatically adjustable in height axially relative to an outset position, counter to resistance of a coupling medium.
