Abstract
A refinement introduced in the object of the main patent number 195968 that falls on a process for the manufacture of hollow bodies of plastic material to produce such hollow bodies of remarkable dimensions characterized by the fact of accumulating the plastic material inside a cylinder of which is ejected in the form of a tube by the action of a hydraulically operated piston enclose said tube inside a mold and inflate it with a fluid under pressure to conform it making it adhere to the walls of the mold.
