Abstract

Extrusion blow molding machine for making plastic bottles comprises an extrusion head (3) mounted on a swiveling frame (5) so that it can be raised or lowered with respect to the extruder (2). In order to reduce the load on the drive system (12) an air spring (13) is mounted on the column (6) which supports the frame at the opposite end to the pivot (8).
