<p>This invention relates to a tube finning machine, i.e. to a machine adapted to fit one or more fins onto one or more tubes. The tube finning machine has a base with a primary axis and a mounting part upon which a plurality of tubes can be mounted in a desired array. The tubes are aligned with the primary axis. A carrier locates a number of fins and a drive means, suitably hydraulic, moves the carrier relative to the mounting part in the direction of the primary axis in order to drive the fins onto the tubes. The machine can be adjusted to fit a variable number of fins to a variable array of tubes. The mounting part and the carrier are both movable relative to the base in the direction of the primary axis, and the mounting part is movable relative to the base between a number of predetermined mounting positions. The length of the tubes to which fins can be fitted is therefore also variable, and may for example be up to 12 metres.</p> |
