Abstract

Gruppo (1) di rullatura interna per pneumatici (2) di veicoli stradali, in cui due unità (50) di rullatura contrapposte sono atte a penetrare assialmente all'interno di uno stampo (4) toroidale di formatura di un pneumatico (2), e sono provviste, ciascuna, di un rullo (80) girevole attorno ad un proprio asse (79), ed atto ad essere spinto verso una superficie interna (82) del pneumatico (2) stesso, e ad essere progressivamente ruotato attorno ad un ulteriore asse (61), sostanzialmente trasversale ad un asse (21) dello stampo (4), per schiacciare progressivamente zone successive del pneumatico (2) a contatto della superficie interna (10,17,13) dello stampo (4) quando lo stampo (4) stesso viene portato in rotazione attorno al proprio asse (21) da un dispositivo (19) di azionamento costituente parte del gruppo (1) di rullatura.
