METHOD AND DEVICE FOR PRODUCING A HONEYCOMB BODY

摘要

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.
