This invention relates to a tube finning machine ( 10 ) and to a method of use thereof. Typically, the finned tubes will be for use in heat exchangers. In the present invention, the machine ( 10 ) has tensioning means ( 32, 44 ) for applying tension to the tubes ( 16 ) during the finning process, tension in the tubes reducing the likelihood that the tubes will buckle or deform during the process. Also, the invention discloses the use of a solid material introduced between the fins ( 22 ) to support the fins during the finning process, the solid material being removed after completion of the process. The solid material can be a granular material, or it can be a continuous material introduced (and removed) in its liquid state. |
