In the area of manufacturing peel-off lids (28) out of lid rings with a peel-off foil (25) sealed on it, a part of the sealing surface (26) is bent up in the direction of the lid edge in order to tension the sealing surface with the peel-off foil. A clamping tool (30, 31) is provided in order to clamp the sealing surface with the peel-off foil and a pressing tool (35) in order to bend up the unclamped sealing surface section (26′).
