CORPO COMPRENDENTE CANALI FORMATI DA FOGL ONDULATI, PARTICOLARMENTE PER LA COMBUSTIONE CATALITICA DEI GAS DI SCARICO DI MOTORI, E PROCEDIMENTO PER LA SUA FABBRICAZIONE

摘要

A method of manufacturing a body having channels extending through it and a body so formed. The method comprises the steps of working a single strip of material to provide corrugations the crests and valleys of which extend in a direction across the strip. The strip is then folded about an axis which lies at an angle to the crests of the corrugations in order to form layers each having the crests of the corrugations angled to, and lying across the crests of the corrugations of an adjacent layer or adjacent layers.
