Abstract
Improvements in extruder spindles for thermoplastic synthetic resins, characterized in that the cooling of such spindles is achieved through a cylindrical axial cavity of the same spindles, closed at both ends, in which a concentric conduit is housed, with open and separated ends of the periphery of the cavity, said duct being carried on its outer face of a helical laminar winding that spans the space between the duct itself and the wall of the cavity, so that said sheet, under the rotation of the spindle, causes the displacement in a closed circuit of a refrigerant liquid contained in the hole, making the journey in one direction through the space covered by the propeller, and the consequent return in the opposite direction through the interior of the conduit, in order to establish the suitable thermal exchange with the spindle.
