Verfahren und Blechpaket zur Herstellung eines Wabenkörpers mit einer Vielzahl von für ein Fluid durchlässigen Kanälen

摘要

To produce a honeycomb body with a plurality of channels through which a fluid can flow from a plurality of at least partly structured metal sheets the invention provides for at least one stack to be created from a plurality of at least partly structured metal sheets. Each stack intended for the formation of a sheet metal pile is folded in on itself along a bend line such that the sheet metal pile has a curved first end area and a second end area situated opposite the first end area. The second end area is formed by a first end section and a second end section of the stack. The first section forms a first angle alpha with its first face and a central plane and the second end section forms a second angle beta with its second face and said central plane, the first angle alpha being smaller than the second angle beta . Each sheet metal pile is held by a twisting device arranged in the central area of a mould and by the relative rotation of the twisting device in relation to the mould is twisted to form a honeycomb body.
