Title:
METHOD FOR MANUFACTURING HONEYCOMB STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2003/082537
Kind Code:
A1
Abstract:
A method for manufacturing a honeycomb structure, characterized by comprising a forming step of extruding and forming a formed body (1) having an outside wall, a partition wall placed inside the outside wall, communicating holes partitioned by the partition wall and axially penetrating through the formed body, and a drying step for drying the formed body (1), a step of receiving the formed body using a receiving jig (10) such that the inclination angle of a face (7a) of the outside wall on the jig (10) with respect to the horizontal plane is between 15 and 35 degrees, such that the receiving jig has a cross-sectional shape with a cut-in portion at the vertex of a V shape and the inclination angle of the face (7a) on the jig with respect to the horizontal plane is between 15 and 45 degrees, or such that the jig receives the formed body at one face of the outside wall, and a step of drying the formed body (1) received by the receiving jig (10) having a predetermined inclination angle. The method reduces bending and deformation of the honeycomb structure.
