Nueva polea para máquinas de hilatura caracterizada por el hecho de haberse previsto su constitución a base de un casquillo central al que se acoplan dos planchas delgadas circulares que en su borde se fijan a un aro que forma el canto de la polea obteniendo una ligereza tal que permite las puestas en marcha y frenados con el máximo de rapidez al suprimir prácticamente la inercia de la polea.
