Pultrusion process to form specially shaped pieces for transforming electric current into diffused heat

Process to form shaped pieces (105), by pultrusion, for transforming electric current into diffused heat, with reinforcing fibers (60, 65) and a matrix of plastic material (50), characterized in that one or more nets (72, 73) are inserted, continuously, into the plastic material (50) said nets, consisting of a continuous wire (74) of electrically conductive material (77) coated with highly insulating material (78), being formed in the direction of feed of the shaped piece (105), thereby establishing electrical continuity from start to finish of formation of said shaped piece (105), wherein the one or more nets (72, 73) are placed continuously in the shaped part (105) but are separated in lengths (85, 86) connected by pairs of devices (111, 112) for electric sockets.
