Abstract:
1. A device for applying a coating film ( 63 ) on a face ( 108 ) of a lens ( 100 ), the film previously being placed on the face concerned of the lens, the device comprising: a seat ( a membrane ( inflater means ( the device being characterized in that the inflater means ( 61 ) comprise a first plate ( 66 ) and a second plate ( 65 ) between which the membrane ( 62 ) is placed, the first plate presenting a setback pressurization chamber ( 80 ) connected to a source ( 93 ) of compressed gas, and the second plate presenting a protrusion opening ( 71 ), and in that it includes mechanical connection means ( 76 , 77 , A 6 ) connecting the plates ( 65 , 66 ) together while enabling them to move relative to each other between an open configuration in which the two plates are spaced apart from each other so as to enable the membrane ( 62 ) to be inserted or replaced, and a closed configuration in which the two plates ( 65 , 66 ) are placed one against the other in such a manner that firstly the pressurization chamber ( 80 ) of the first plate ( 65 ) and the protrusion opening ( 71 ) of the second plate ( 66 ) are situated facing the inflatable portion ( 62 B) of the membrane ( 62 ), and secondly the peripheral fixing portion ( 62 A) of the membrane ( 62 ) is held by being pinched between the two plates ( 65 , 66 ), the mechanical connection means ( 76 , 77 , A 6 ) of the plates ( 65 , 66 ) being such that the mechanical connection they provide is conserved in the open configuration.
