Patent ID: 8141220

Claim:
A process for uncoupling a support and for removal of a protection film placed on lenses during manufacturing thereof, and subsequently to machining and polishing said lenses, each lens supplied with the protective layer on a front side where a machining support is assembled thereto using a layer of melted material, the process comprising: softening of the layer of melted material by applying a warmed fluid to a set of the lenses and to the support; projecting a pressurized lateral jet of warmed fluid onto the support to cause detachment and separation of the support from each lens; variably projecting a pressurized lateral jet of warmed fluid at a variable orientation, for acting on a contour of each lens by rotating the lenses around a longitudinal axis thereof for applying the variable orientation jet onto the entire contour of said lenses, in order to cause the protective layer to lift and progressively separate from a contour of the lens until there is a complete removal of the protective layer from the lenses; and, draining the warmed fluid from the lenses.
