ABSTRACT:
The blades for optical shutters of cameras, lenses or the like are obtained from a sheet made by electrodeposition, for example a nickel sheet. Thereby, subsequent working operations such as hammering, riveting may be carried out on the whole sheet. The sheet has a series of individual blades which are obtained on their peripheries by small lugs and which may be readily detached from the rest of the sheet.
