P Vibration damper with double tubes (3, 5), closed by radial bending of an upper end part (21) of the outer cylinder (3), which is then folded inwards in a radial direction. This bending operation is carried out using a bending roller (17). This is tilted around a tilting axis (b, b), substantially tangent to the surface of the bending roller (17) and substantially tangent to the cylinder (3), adjacent to the upper end part (21) of the latter. /P
