Abstract
To place an insert cut out of film with no gaps in a cavity formed in a foil, after placing the foil on a supporting substrate, the cavity is punched into the foil by means of a tubular cutting punch comprising an inner pusher with a cutting edge in the required shaped of the cavity and the insert, so that the edge goes through the thickness of the foil and cuts a slug out of it; the punch is lifted with the slug held inside the punch, without moving the foil, the film is brought between the foil and the edge of the punch, the punch is lowered once again so as to cut the insert out of the film and then push the insert cut in that way in the cavity with a pusher, and the punch and the pusher are removed, with the insert held in place in the cavity.
