Abstract

Dispositivo meccanico di centratura automatica di nastri continui ad anello in movimento su due rulli, uno motore e uno tenditore, specialmente di un nastro smerigliatore su rulli a sbalzo di smerigliatrici per pavimenti. Il rullo tenditore (1) ha due porzioni: una, minore (3), vicina ad un supporto (5) dell'albero (2) del rullo (1) montata girevole, ma non inclinabile rispetto all'albero (2), su un manicotto girevole eccentrico (11) con la sua parte più vicina al supporto (5) troncoconica, e l'altra, maggiore (4), girevole su una bussola (12) coassiale all'albero (2) del rullo (1) ed inclinabile su uno snodo sferico (13), ma non girevole, rispetto all'albero (2). Sono inoltre previsti un vincolo unilaterale a sfera di contatto (15) fra manicotto (11) e detta bussola (12) ed almeno una molla (16) che tende ad inclinare detta bussola (12) rispetto all'albero (2) del rullo (1) nel senso consentito da detto vincolo.
