付けするかして固定するものであった。Conventionally, as a manufacturing method for this type of metal support matrix, heat resistance, for example, has been used to sufficiently deal with high temperature resistance and vibration resistance during use, and to obtain a large supporting area per unit volume. A wavy metal strip and a flat metal strip made of relatively thin walls are stacked on top of each other to form a layered, or even spiral, laminate, and the laminate is housed in a casing. In this state, the laminated parts at both side edges, and the laminated body and the casing are fixed by spot welding or soldering.

を生ずる問題を有するものであった。In addition, when soldering is used, the low melting point of the solder makes it difficult to withstand the high temperature atmosphere caused by exhaust gas, and together with the vibration of the vehicle body, it often causes noise in the interior laminated body. However, there have been problems such as mutual misalignment and other problems.

造法を提案することを目的とするものである。In order to very effectively solve the above-mentioned conventional problems, the present invention provides a method in which at least one surface of the strips in which the strips come into contact with each other is coated with a copper plating film or coated with steel. A foil material is laid or molded into the laminate, and the whole is heated while being encased in a casing to melt the copper plating film or the copper foil material so that at least the stacked contact surface is formed. By brazing and fixing the parts, it is extremely easy to solder and fix them all at the same time, which greatly improves productivity. Furthermore, the reliable soldering prevents the noise caused by the stacked laminates, or the mutual positioning. The object of the present invention is to propose a method for producing a metal-supported matrix for an exhaust gas purifying catalyst that does not cause problems such as misalignment.
