Abstract:
A method for producing a catalytic converter, comprising:wrapping a mineral fiber positioning mat around a monolith packet to form a monolith packing; radially prestressing the mineral fiber mat; pressing in a pressing-in direction the at least one monolith packing into a tube section forming a positioning area, the tube section being utilized to increase restoring forces exerted by the mineral fiber mat onto the monolith, the positioning area comprising at least two longitudinal sections that extend parallel to a longitudinal axis of the tube section, wherein at least two of the longitudinal sections have different internal cross-sectional area such that the longitudinal sections decrease in cross-sectional area in the pressing-in direction and the monolith packing is pressed in starting from a tube end having a larger cross-sectional area.
