1. A tube shaping machine comprising a plurality of dies each having a substantially continuous, unbroken working surface, a substantially straight support leg for supporting said working surface and for defining lateral side portions thereof and forming a predetermined angle with respect to said working surface, and a substantially straight actuating leg for driving said support leg and formed continuously therewith and at a second predetermined angle with respect thereto, means for mounting said dies and for aligning said working surfaces one adjacent to the next so as to form a tube-receiving aperture therethrough, which aperture defines in cross-section a regular polygon, and means for simultaneously reciprocating each of said plurality of dies along a predetermined straight line throughout a range of positions between a fully open position and a fully closed position of said tube shaping machine while maintaining a similar regular polygonal cross-sectional shape of said tube-receiving through aperture throughout said range of positions.
