A method for producing a honeycomb body having a plurality of at least partially structured sheet metal layers and formed with a plurality of channels through which a fluid can pass, comprises the steps of forming a stack by layering a plurality of at least partially structured sheet metal layers such that the channels are formed and then introducing the stack into a mould. The stack is held in the mould with a wrapping device and with positioning elements, which at least partially reach into the channels in a central region of the stack. The wrapping device is pivotable around a winding axis and has at least two winding bars located essentially parallel to the winding axis and extending along a longitudinal direction of the channels. The at least two winding bars engage the stack at a respective exterior surface at the central region of the stack. The stack is wrapped until a predetermined degree of wrapping of the stack is attained, while maintaining, in the central region of the stack, a structural configuration having structures disposed relative to one another and formed by the at least partially structured sheet metal layers.

[ We claim:] [1.]1. A method for producing a honeycomb body having a plurality of at least partially structured sheet metal layers and formed with a plurality of channels through which a fluid can pass, the method which comprises:a) forming a stack with a plurality of at least partially structured sheet metal layers defining channels and with a central region, the channels defining a longitudinal direction;b) introducing the stack into a mould;c) holding the stack in the mould with a wrapping device and with positioning elements reaching at least partially into the channels in the central region of the stack, the wrapping device being pivotable around a winding axis and having at least two winding bars located essentially parallel to the winding axis and extending along the longitudinal direction of the channels, the at least two winding bars engaging the stack at a respective exterior surface at the central region of the stack; andd) wrapping the stack until a predetermined degree of wrapping of the stack is attained, while maintaining, in the central region of the stack, a structural configuration of structures disposed relative to one another and formed by the at least partially structured sheet metal layers.
