A heating disk for heating up a stream of exhaust gas and/or a component for exhaust gas aftertreatment has a honeycomb body, wound from a plurality of smooth and corrugated metal layers stacked on top of one another. The honeycomb body is received within a carrier shell and an electrical contact is fed through the carrier shell. The honeycomb body is connected to a current source via the electrical contact. The electrical contact has a contact strip within the carrier shell extending in the circumferential direction of the carrier shell. An insulating region is formed between the carrier shell and the contact strip. A plurality of stacks of layers are electrically insulated from one another. Each of the stacks of layers are formed from the plurality of smooth and corrugated metal layers, and which are arranged directly adjacent to one another and conductively connected to the contact strip.

Electrically heatable heating disk for exhaust gas aftertreatment

A method for producing a honeycomb body for a catalytic converter for treating exhaust gases, the honeycomb body having a plurality of flow ducts, through which gas flows from an inlet end to an outlet end. The honeycomb body is formed from a plurality of metal layers lying one on top of the other. The honeycomb body is produced by forming corrugated sections in a metal strip, wherein the corrugated sections follow one another directly or are spaced apart by smooth sections, creating a pre-bend of the metal strip in the end region of each section, folding the individual sections of the metal strip onto one another to create a layer stack, wherein the individual sections are alternately folded onto one another in opposite directions, inserting the layer stack in a housing, and joining the layer stack to the housing in contact regions between the layer stack and the housing.
