HONEYCOMB MAIN BODY, DEVICE TO CLOSE PASSAGE OF HONEYCOMB MAIN BODY, AND PROCESS AND DEVICE TO MANUFACTURE HONEYCOMB MAIN BODY

摘要

PROBLEM TO BE SOLVED: To provide a process and a device to manufacture a honeycomb main body, which can reduce the effect of a rod passage. SOLUTION: A process and a device in order to manufacture a honeycomb main body having a plurality of sheets 3, 4 wherein a structure to form a plurality of passages 2 in which a fluid can pass, is at least partially provided, are provided. In this case, a plastic deformation is performed regarding at least one part of the sheets 3, 4 in the area of a rod passage 9, and the cross section of the rod passage is substantially specified by the bar of a winding device. At least a free stream cross section of the rod passage 9 is at least partially closed in the flowing direction of an exhaust gas, by a deforming punch 6 having a sharp edge rim 8 on an end part 7.
