Abstract
Un dispositivo per il fissaggio di un cilindro di avvolgimento per un rotolo di materiale fotografico, preferibilmente carta fotografica, sul nucleo di una flangia porta-bobina, in cui, attraverso una leva con un corrispondente comando, una parte di forma anulare dell'anima stessa può essere divaricata, così da premere dall'interno contro il cilindro di avvolgimento medesimo, è configurato in modo che i settori (9), formano un anello, essendo costituiti da materiale essenzialmente rigido; inoltre, i settori (9) alloggiati nella flangia porta-bobina (1) si possono muovere nel senso di un ingrandimento diametrale; intervenendo su di essi un divaricatore (7), attivabile mediante un comando (6a). Il dispositivo di bloccaggio è costituito da pochi componenti, agevolmente montabili.(Figura 1).
