Abstract
Apparatus for forming a honeycomb structure capable of adjusting a shaping speed of an outer skin of the honeycomb structure, thereby preventing a defect in the skin. The shaping device is constructed by a die (10) having slits (11) for formation of a honeycomb structure and a guide ring (2) arranged downstream of the die (11). The guide ring includes an opening with an inner edge (21) and includes at a location upstream from the edge a pool portion (22) for the formation of a skin of the honeycomb structure. A temperature controller (3) is arranged in the guide ring for controlling a heating on a cooling of a ceramic material held in the pool portion (22).
