The present inventors have found that, in the above-mentioned conventional example in which the winding tension of the metal flat foil and the metal corrugated foil is kept constant in the main winding process, the joint portion is stable when the metal flat foil and the metal corrugated foil are joined. As a result of various studies on the reason for not doing so, it was found that the reason why the joint is not stable is that the winding tension in this winding process is constant.

When the winding radius r x changes to r, the wave pitch angle θ x from the center of the metal wave foil 2 changes to θ. For example, when the wave pitch of the metal corrugated foil 2 is 2.5 mm and the winding radius radius r x is 15 mm, the angle θ x is 2πr x × θ x /360°=2.5 mm θ x = 360 ° × 2 In the case of 0.5 mm / 2πr x radian display, θ x = 2.5 / 2: radian θ x = 360 ° × 2.5 mm / 2π × 15 mm = 9.554

On the other hand, the force acting on the metal corrugated foil 2 by the flat metal foil 1 to which the tension T is applied at the point A, the acting force P is P = 2T sin (θ / 2) as shown in FIG. The smaller the angle θ, the smaller the acting force P. As a result, the winding radius r
Becomes larger, the angle θ becomes smaller, the acting force at the contact portion between the metal flat foil 1 and the metal corrugated foil 2 becomes smaller, and if the plate thickness of the metal flat foil 1 is constant, the contact length L (FIG. 2) becomes short. And the joint length becomes shorter. Such a change is caused by the angle θ
In consideration of the above, it is possible to suppress it by maintaining the acting force P on the flat metal foil 1 and the corrugated metal foil 2 constant.
