Abstract
A method for the production of filaments (A) capable of being thermoregulated includes the steps of: —feeding a material to be extruded and a pair of wires (B) in electrically conductive material to an extrusion head (1); —extruding the material to be extruded and, at the same time, promoting the escape of the pair of wires (B) from the extrusion head (1) in such a way that the material to be extruded winds the pair of wires (B); —during the extrusion, generating at least a coupling portion (Y) of the filament (A), wherein the pair of wires (B) is electrically connected.

Method for the production of filaments (A) capable of being thermoregulated comprising the steps of:
- feeding a material to be extruded to an extrusion head (1);
- feeding a pair of wires (B) of electrically conductive material to said extrusion head (1);
- extruding the material to be extruded and, at the same time, promoting the escape of the pair of wires (B) from the extrusion head (1) in such a way that the material to be extruded winds at least partially and at least locally said pair of wires (B);
- generating, during the extrusion, at least a coupling portion (Y) of the filament (A) wherein pair of wires (B) is electrically connected, said coupling portion being preferably arranged internally to the material to be extruded.
Extrusion head comprising:
- a first nozzle (2) that can be connected to at least one propeller to receive from said propeller a material to be extruded and configured to extrude said material along an extrusion direction (X);
- an insertion device (3) configured to receive in feed a pair of wires (B) in electrically conductive material and having a pair of delivering seats arranged to deliver respective wires (B) along the extrusion direction (X);
- said first nozzle (2) being associated with the insertion device (3) so as to extrude the material to be extruded around the pair of wires (B) exiting the extrusion head (1) by completely winding them.
