ABSTRACT:
The invention provides for a method of and an apparatus for manufacturing finned tubing from tubular metal fin stock in which the fin stock is in axially continuous form. There are provided at least two finned regions on the fin stock between which there is interposed at least one finless region. A plurality of rollers are employed which are drivably mounted on arbors spaced about the fin stock. Each roller includes a plurality of axially arranged forming discs, the discs on the arbors tracking each other in axially spaced groups, and the diameters of the forming discs in each tracking group on the arbors having different diameters. The fin in a finned region is developed to its full height over an axial distance of the fin stock equal to from 0.40 to 0.75 of the outside diameter of the fully developed fin.
