Recently, application of a diffusion bonding method and a liquid phase bonding method has been attempted as the bonding method.

り、なお改善すべき点が残されている。However, in the case of the conventional winding method in which the winding tension is kept constant in the main winding, the flat metal foil is generated due to the change in the winding tension due to the change in the winding diameter. Due to changes in the contact surface pressure and contact length at each contact part of the metal foil and the metal corrugated foil, the surface pressure and the bond length are likely to become unstable, and it is difficult to obtain stable bond quality, which should be improved. Points are left.

In the method for winding a honeycomb body, at least the winding core (2
In the main winding and winding process after formation, the winding tension is increased according to the increase of the winding diameter, and a constant contact surface pressure is applied at each contact portion of the flat metal foil and the corrugated metal foil. In addition, the contact length is kept constant and the quality of the bonded portion is stabilized, which is a method for winding a metal honeycomb body.

This means the portion and the length of the foil and the metal corrugated foil that are actually joined together by the joining process.

安定な金属ハニカム体を製造することができる。In the present invention, the contact tension and the contact length between the flat metal foil and the corrugated metal foil are stabilized by increasing the winding tension in accordance with the increase of the winding diameter in the winding process of the metal honeycomb body. When the flat metal foil and the corrugated metal foil are bonded to produce a product, the quality of the bonded portion can be stably secured, and a metal honeycomb body with stable quality can be manufactured.

に起因しているということを知見した。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.

た場合の角度θは、 θ＝３６０°×２．５mm／２π×５０mm＝２．８６６° と大幅に小さくなる。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
°. However, here, when the winding radius r is 50 mm, the angle θ is significantly reduced to θ = 360 ° × 2.5 mm / 2π × 50 mm = 2.866 °.

に維持することにより抑えることが可能である。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.

It has been found that by changing the winding tension T according to the change of the winding radius r, the contact action force P and the contact length L are kept constant, and stable winding is possible.

It is premised that the metal flat foil 1 and the metal corrugated foil are stably joined. In this case, for example, as shown in FIG. 2, the contact acting force at the contact portion between the metal flat foil 1 and the metal corrugated foil 2 is used. In the main winding process after forming at least the winding core portion (for 2 to 3 windings) so that the surface pressure and the joining length become constant while P is kept constant, the flat metal foil is increased in accordance with the increase of the winding diameter. It is characterized in that the winding tension is increased.

The increase of the winding tension may be started in the process of forming the winding core (for two to three windings), but it is more effective to start from the starting winding point after the winding core is formed.
