Abstract

Polea para correas, con diámetro de trabajo variable, especialmente polea motriz para la correa de un dispositivo alimentador de hilo en máquinas textiles, preferiblemente tricotosas, constituída por dos discos coaxiales que pueden girar relativamente uno respecto al otro, y de los que uno presenta una ranura de guía radial y el otro al menos una ranura de guía en forma de espiral, y por elementos sustentadores con una forma a modo de segmentos que, con sus lados frontales, pueden aprisionarse entre los discos, en diferentes posiciones radiales que, en cada caso con sus zonas posteriores situadas al exterior, definen juntamente una línea poligonal similar a un círculo, y que con unos salientes encajan de tal manera en las ranuras de guía de ambos discos que, en caso de giro relativo de los discos y variando el correspondiente diámetro de círculo, son desplazables en sentido radial.
