The present invention relates to a method for producing a blow-molded tubular body having multiple dimensions with the following stages: a) extrusion of a tubular component that is closed at the front, with injection of gas inside the tubular component (10), and engagement of the tubular component with a shaping unit (12, 13), b) deposition of the shaped tubular component, in the plastic state, on a high-level half-mold part (15), c) free descent of a part of the tubular component onto a low-level half-mold part (18), located at a level that is lower than that of the high-level half-mold part (15), d) closure of the half-mold and blow-molding. The invention furthermore relates to a device for producing a blow-molded tubular body having multiple dimensions, which includes: a shaping unit (12, 13) to form the shape of the tubular component (10) before deposition on a half-mold (15, 18); a nozzle (21) for the injection of gas inside the tubular component (10) during an extrusion; a conveyor (22) device to convey the tubular component (10) during the extrusion and allow an engagement of the shaping unit (12, 13). |
