PROCESS AND MEANS FOR MAKING AND USING OF FOOTWEAR BIPOLAR LASTS, PARTICULARLY ADAPTED TO SELF EXTENDING TO STRESS THE SHOE OR THE LIKE BEING SHAPED, AND LASTS OBTAINED WITH SUCH PROCESS AND MEANS

摘要

A footwear bipolar last, is adapted to self extending and to stress the shoe or the like being worked thereon. The coupling (333) provided between the two polar bodies (2, 2') of the shoe last (2, 333, 2') comprises at least a longitudinal guide (3) substantially axial which adjusts the shifting between the two components (2, 2') in a range comprised between 5 mm and 30 mm, keeping them in line and in the same direction and comprising a spring (30) which permanently and intensely forces the two polar bodies (2, 2') in the most mutually allowable far apart position.
