ABSTRACT:
The invention relates to an extruded honeycomb structure in which every cross-section is rotationally displaced from other cross-sections. The cells are twisted and as a result, are not parallel with the axis of extrusion. The twisted cells are formed by passing plastically deformable material through a die and twisting or rotationally displacing the extrudate around its central axis to obtain a twisted honeycomb structure.
