摘要： A process of manufacturing fin tubes consisting in cutting series of metal plates of desired length from metal strips, feeding said plates in a guide towards the outer periphery of a tube and fastening the plates e.g. by welding by their end edges in a circular or helical row onto the outer surface of the tube, so that the length of the plates corresponds to the height of the fin formed of the plates, thus permitting the adjustment of the height of the fin solely by cutting metal plates of different length from one single strip or strips of the same width. A machine for performing the process consists of a device for feeding loose metal plates cut from a strip of determined width in a row into a gutter-like guide, means for moving said plates along said guide in desired spacing relation towards the outer periphery of a tube, means for rotating said tube and possibly also for longitudinal displacement thereof relative to said gutter-like and means for welding said metal plates with their end edges onto the tube in a row to form a fin thereon.
