Abstract

Un cerchietto (2) viene coassialmente disposto attorno ad un tamburo di supporto (6) portante una camera gonfiabile (7) predisposta in condizioni di degonfiamento. Settori di presa (14) circonferenzialmente distribuiti nel tamburo vengono radialmente accostati alla superficie interna del cerchietto (2) per fare aderire contro il medesimo una porzione centrale di una struttura nastriforme di rivestimento (3) predisposta attorno alla camera gonfiabile (7).La camera viene gonfiata a formare, da parti opposte rispetto al cerchietto (2), due lobi (17, 18) confinati ciascuno fra la superficie esterna del tamburo (6) ed una rispettiva campana di contrasto (19, 20) circoscrivente coassialmente il tamburo. Con una movimentazione assiale delle campane di contrasto (19, 20), un primo ed un secondo lembo laterale della struttura di rivestimento (3) vengono applicati su rispettive superfici del cerchietto (2). Il secondo lembo si sovrappone al primo lembo fissandosi a quest'ultimo sulla superficie radialmente esterna del cerchietto (2).
