Abstract (en)
[origin: EP1151811A2] To produce a hollow honeycomb cylinder it is forced by a press roller (28,29) against supports on a die (15) and rotated, against the roller rotation. The supports form the outer surface of a cylinder segment, with a radius matching the radius of the hollow cylinder (100). During the rotation, the honeycomb structure is embossed without slipping at its inner wall.
