Abstract
Improvements in the manufacture of hollow bodies in plastic material by insufflation, according to the method of forming by extrusion or injection a tube inside which air is blown, characterized by holding and retaining the open end of a tubular element of plastic material after its exit through an ejection nozzle, then forming inside a mold and starting from said tubular element a hollow body by the combined action of a relative displacement of said end with respect to said nozzle and a gas insufflation performed in the opposite direction to the exit direction of the plastic material.
