Process for producing tubular shaped pieces (105) having a rectangular cross section of low height, to transform electric current into diffused heat, by means of pultrusion, with continuous formation, added to known reinforcing materials such as roving (60) and mats (65) of fibreglas, on one broad side of the shaped piece (105), of one or more parallel nets (72, 73) of a weft woven (80, 81) fabric made from a continuous wire (77) of highly conductive material coated with insulating material (78), connected at set intervals to devices (111, 112) of electric sockets incorporated in the plastic material (50) so that, when the shaped piece (105) is cut through at the position of the devices (111, 112) to form electric sockets, and by filling the panels with insulating foam material (145) oblong panels (116) are obtained utilizable for innumerable purpose |
