Abstract:
1. A honeycomb body, comprising: a casing tube; a honeycomb structure connected to said casing tube and defining an axial portion between said casing tube and said honeycomb structure; an inner sleeve being a sheet metal foil at least partially surrounding said honeycomb structure; an outer sleeve being a sheet metal foil at least partially surrounding said honeycomb structure; said inner and outer sleeves being disposed in said axial portion; said sleeves having structures for compensation of changes in circumference of said honeycomb structure, said structures of said inner sleeve and said structures of said outer sleeve being configured for engaging in one another and adjacent structures of said sleeves being configured for at least partially contacting one another, thereby defining a zone of friction between said inner sleeve and said outer sleeve and impeding a relative movement of said sleeves in relation to one another; and a plurality of joining locations adjacently interconnecting said honeycomb structure, said inner and outer sleeves and said casing tube to form an open spring/damper system from at least one of said sleeves.
