Abstract
Dispositivo per la formatura di pneumatici, in cui un tamburo (6) unistadio è provvisto di un albero interno (7), una cui porzione intermedia porta calettato un dispositivo di rullatura interna (11), e due cui porzioni di estremità, disposte da bande opposte del dispositivo di rullatura (11), supportano due semi-tamburi (12, 13), i quali sono accoppiati all'albero interno (7) tramite l'interposizione di rispettive slitte (18), ciascuna delle quali è accoppiata da una parte in modo scorrevole ed angolarmente fisso all'albero interno (7), e dall'altra in modo girevole al relativo semi-tamburo (12) (13), il quale può essere bloccato rispetto alla relativa slitta (18) tramite un giunto a frizione (53).
