Abstract
Procedure for the continuous production of profiles of constant section and apparatus for its realization, particularly of solid cylindrical bars of thermoplastic material, by consecutive extrusion and deformation and cooling of the molten material within a calibrator-cooler, characterized by continuously sending molten material, driven By the screw of an extruder, to a heated extrusion head that has a free hole, said molten material be allowed to solidify in a water jacket type calibrator-cooler, initially by direct contact of the initial internal surface of the calibrator with the melt and then by the action of a liquid film interposed between the internal surface of the terminal part of the gauge and the solidifying bar, then oppose to the advance of the bar a continuous brake action, regulated in such a way that a back pressure to the flow of material generated by the extruder, and p or last cool the solidified bar completely.
