Apparatus for the extrusion of thermoplastic tubes, characterized essentially by the fact of comprising an annular extrusion die, connected with an extruder mechanism of thermoplastic material, and an annular nozzle surrounding the mouth of said die, is connected with means supplying air to pressure and whose mouth is oriented so as to direct a stream of tubular air brushing the outer wall of the extracted tube, in a soft state, in the same direction of movement and so that it applies an aerodynamic action that tends to widen it.
