Abstract

Per trasportare nastri o fogli di carta viene proposto un rullo, il quale è costituito di un corpo del rullo con un mantello cilindrico ed una boccola (1) racchiusa dal mantello. Il corpo del rullo presenta un'apertura passante coassiale, in cui con il suo allargamento è possibile introdurre a pressione un albero (3). Il lato interno della boccola (1) delimitante la apertura passante è dotato in distribuzione uniforme sul suo contorno di sporgenze (2), che si estendono in direzione assiale e sono orientate verso l'interno. Introducendo a pressione l'albero (3) nella boccola (1) del corpo del rullo le sporgenze (2) vengono spostate forzatamente radialmente verso l'esterno e provocano un accoppiamento solidale alla rotazione fra il corpo del rullo e l'albero (3).(Figura 1c).
