This invention relates to a tube finning machine, and in particular to improvements to such a machine. The invention relates to the field of heat exchangers, and in particular to the fitment of extended surface members (or fins) to the tubes of a heat exchanger so as to enhance the heat exchange. The tube finning machine has a rigid base, a clamping means for clamping a number of tubes, a carrier means movably mounted to the base, and a drive means by which the carrier means may be moved to a predetermined position relative to the base, and therefore relative to the tubes clamped thereupon. The improvements disclosed include those relating to support means for the tubes, clamping means for the tubes, and guide means for the fins as they are delivered to the carrier means.
