METHOD AND SHEET METAL PACK FOR MANUFACTURING A HONEYCOMB BODY WITH A LARGE NUMBER OF FLUID PERMEABLE CHANNELS

IN ORDER TO MANUFACTURE A HONEYCOMB BODY WITH A LARGE NUMBER OF FLUID PERMEABLE CHANNELS FROM A LARGE NUMBER OF AT LEAST PARTLY STRUCTURED SHEET METAL LAYERS, IT IS PROPOSED THAT AT LEAST ONE STACK (27) IS LAYERED UP FROM A PLURALITY OF AT LEAST PARTIALLY STRUCTURED SHEET METAL LAYERS (28, 29). EACH STACK (27) FOR FORMING A SHEET METAL PACK AGE (1, 2, 3) IS FOLDED ONTO ITSELF ALONG A BENDING LINE (21, 22, 23) SUCH THAT THE SHEET METAL PACK AGE (1, 2, 3) COMPRISES A CURVED FIRST END AREA (30) AND A SECOND END AREA (31) OPPOSITE TO THE FIRST END AREA (30), WHICH IS FORMED BY A FIRST END SECTION (32) AND A SECOND END SECTION (33) OF THE STACK (27), WHEREIN THE FIRST END FACE (35) OF THE FIRST END SECTION (33) FORMS A FIRST ANGLE (a) WITH A CENTRAL PLANE (34), AND THE SECOND END FACE (36) OF THE SECOND END SECTION (33) FORMS A SECOND ANGLE (b) WITH THE CENTRAL PLANE (34), WHEREIN THE FIRST ANGLE (a) IS SMALLER THAN THE SECOND ANGLE (b). EACH SHEET METAL PACK AGE (1, 2, 3) IS HELD BY A LOOPING MEANS (24, 25, 26) ARRANGED IN THE CENTRAL AREA (7) OF A MOULD (5), AND IS LOOPED INTO A HONEYCOMB BODY (6) BY ROTATION OF THE LOOPING MEANS RELATIVE TO THE MOULD (5).FIGURE 2
