摘要： A method of manufacturing a honeycomb body (1) formed by winding around, stacking, and brazing metal flat foils (3) and corrugated foils (4), characterized by comprising the steps of applying adhesive agent to the brazed portions of the flat or corrugated foils corresponding to the connection part (17) at the end part of the honeycomb body and/or a cross sectional connection part (18) inside the honeycomb body apart axially from the end part, winding around the flat foils and corrugated foils to form a honeycomb body shape, bringing the portion of the honeycomb body end face corresponding to the connection part (16) over the entire axial length of the honeycomb body outer peripheral part into contact with the surface of binder liquid to suck the binder into the contact part (5) between the flat foils and the corrugated foils, and spraying wax powder over the honeycomb body to adhere the wax material onto the adhesive agent and binder adhered parts, whereby the equipment cost of a honeycomb body manufacturing device can be reduced and a measure against fire of the honeycomb body can also be taken without causing a defective coating and an increase in coating area found in the coating of adhesive agent with a roll.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust-gas purifying metal carrier capable of preventing heat transfer from a honeycomb body to an outer cylinder, and increase the amount of exhaust gas supplied to the cells in the outer periphery of the honeycomb body so as to improve the capability of purifying the exhaust gas. SOLUTION: This metal carrier is constituted by a honeycomb body 1 which is formed by alternately winding a flat metal foil and a corrugated metal foil, and a metal outer cylinder 2 having a reduced-diameter portion at both ends. The inner surface of the outer cylinder is bonded to the outer surface of the honeycomb body 1 at a reduced-diameter portion 4 located at an exhaust-gas emitting end face of the outer cylinder. The inner surface of the outer cylinder is in slidable contact with the outer surface of the honeycomb body at a reduced-diameter portion 3 located at an exhaust-gas introducing end face of the outer cylinder. The inner surface of the outer cylinder is not in contact with the outer surface of the honeycomb body between the reduced-diameter portions. Moreover, the foils forming the honeycomb body 1 have a multiplicity of permeable pores at their surfaces. The honeycomb body 1 has a convex shape at its exhaust-gas introducing end face. The metal carrier further includes a stream-regulating honeycomb body.
