This invention is an apparatus, and method for making a transfer device comprising a tube bundle. The transfer device is suitable for use as a heat exchanger in a blood cardioplegia circuit, for example. The apparatus axially winds a flexible tube (30) around a winding core (10). The apparatus includes a winding core, a core rotating means (20), tube bobbin (22), and a tube shuttle to guide the tube around the core. A shuttle rotating means (28) rotates the tube shuttle around the core. The method of making the transfer device includes providing a winding core, winding a tube from end to end around the winding core, fitting the wound bundle into a housing (50), sealing the first, and second ends of the housing using a potting material (60), cutting the ends of the bundle to expose a lumen within the tubes attaching first end cap (56), and second end cap (58).
