ABSTRACT:
Balloon pleating mechanism includes a plurality of pleating dies, each having a first planar guiding surface, a second planar guiding surface, a bearing surface, a first working surface, and a second working surface. The plurality of pleating dies are arranged in a generally circular orientation with the first planar guiding surface of each die being in sliding contact with the second planar guiding surface of an adjacent die and the first working surface and the second working surface of each die of the plurality of dies cooperating to define a central cavity. The plurality of pleating dies is further arranged for relative radial movement between an open position and a closed position. A driving mechanism is coupled to each die and designed to move the plurality of dies between the open position and the closed position.
