Abstract
Improvements introduced in the manufacture of finned tubes, whose manufacture comprises: axially advancing a continuously rotating bare tube and providing, around the outer surface of said tube a substantially continuous fin, of narrowed cross section, so that it is fixed in intimate contact heat transfer with said tube, whose improvements are characterized in that the continuous strip of starting material of the fin is subjected to rolling in a conical mill with the result that the stretching of the fibers of the metal in the outer peripheral zone of the fin and that, simultaneously, the fibers of the base part of the fin do not undergo any substantial deformation, which automatically provides a natural helical winding of the fin finished without any deformation of its smooth lateral faces.
