Abstract
Process for manufacturing flexible pipes from rigid plastic materials, characterized in that an extruder machine is used that provides, in a continuous manner, a smooth plastic tube, so that the outlet nozzle of this machine empties into an apparatus molding consists essentially of a set of half-molds involved in an endless process, between whose half-molds said tube, in soft state, acquires successive expansions in radial direction, caused by a vacuum effect caused from the external part and through the means of molding, so that at the end of these operations the tube offers its final conformation, in a state of stable rigidity and with faculty of bending, becoming winding.
