Abstract (en)
[origin: EP0672606A1] The metal foil union comprises a winding casing, the ID of which corresponds to the OD of a casing receiver. The winding casing is formed as a shaft with hollow chambers. The outer wall (1) or the inner wall of the hollow chamber shaft in the central area has an increased wall thickness and in the wall thickness transition zone an extension with a shrink seat is formed, into which a ring disc is shrunk, which closes an inner chamber between the outer and inner walls (1,2). At the face end of the hollow chamber shaft a ring-shaped flange part (5,6) is arranged, which is firmly connected with the outer and inner walls, thus forming two outer chambers.
