Abstract
In the process of loading successive molds of a multi-station rotary blow molding machine which involves closing mold sections on portions of a continuously downwardly extruding parison adjacent the outlet of an extruder head while the molds continue to move along a circular path, improvements occuring during startup of the machine are provided which comprise directing the parison out of the path while the machine speed is brought up to design rate and then severing the parison at the outlet with a device actuated outside of the circular path and in timed coordination with the position of that mold to be loaded with the next issuing parison portion.
