Abstract: A blow molding machine comprising two calibration stations and an extruder arranged between the two calibration stations. The machine produces hose-shaped parisons to be blown into hollow bodies by mold forms in an alternating sequence and in a periodical sequence at the respective calibration stations. An extruder is located along a vertically extending longitudinal center plane of the blow molding machine along which the mold forms are displaceable back and forth between the associated calibration stations and the extruder. A transport device transports the respective hollow bodies blown at the calibration stations to at least one post processing station in sequence. A transport mask is displaceable back and forth along a transport path disposed at a lateral distance from the longitudinal center plane of the blow molding machine and parallel thereto.

Abstract: A blow-molding machine having two calibrating stations located on both sides of a centrally arranged extrusion station, and including two closing systems, for one set of blow molds each, is equipped with finishing stations arranged along the longitudinal center plane of the blow-molding machine extending at a right angle to the transverse center plane thereof, for performing pinch-off removal, punching and testing operations, for example. The hollow bodies, which have been blown at the calibrating stations, are fed to the first finishing station in alternating succession by a swinging gripper capable of swinging altogether by 180.degree.. The swinging gripper includes a shell closing system arranged for being pivoted about the swinging axis of the swinging gripper and for being displaced radially relative to that axis. In addition, the shell closing system can be rotated by 180.degree..
