Abstract

Uno di due rotori (7, 12) coassialmente ed indipendentemente ruotanti a velocità differenti è provvisto di un foro passante (22) e di un rullo o cilindrino (20) montato per ruotare in modo folle attorno ad un asse parallelo e decentrato rispetto all'asse comune dei due rotori (7, 12); sull'altro (12) di detti rotori una pista anulare interna (14) rigida è montata con interposizione di un anello (16) ad elevata cedevolezza elastica. Al primo rotore (7) è solidale una appendice (107) sagomata per circondare parzialmente il rullo o cilindrino (20) e formare carter guidafilo. (FIG. 1)One of two rotors (7, 12) coaxially and independently rotating at different speeds is provided with a through hole (22) and a roller or cylinder (20) mounted to rotate idly around a parallel and decentralized axis with respect to the common axis of the two rotors (7, 12); on the other (12) of said rotors a rigid internal annular track (14) is mounted with the interposition of a ring (16) with high elastic yielding. An appendix (107) shaped to partially surround the roller or cylinder (20) and form a wire guide casing is integral with the first rotor (7). (FIG. 1)
