An apparatus for molding a honeycomb structure provided with an extruder for the honeycomb structure capable of extruding a honeycomb structure in the gravity direction or an oblique direction at an angle of smaller than 30° with the gravity direction and at least one cradle, said apparatus being provided with a means of being able to place the honeycomb structure extending in length with progress of extrusion on the cradle with cell opening end face 9 of the honeycomb structure being pressure contacted with the cradle under a pressure smaller than the compressive strength at the end face and then to move the cradle at a speed capable of keeping the pressure contact state and in the same direction as the lengthwise direction of the honeycomb structure.
An apparatus for producing a honeycomb structure provided with an extruder capable of extruding a honeycomb structure in the gravity direction or a direction oblique at an angle of smaller than 30° with the gravity direction and at least one cradle, said apparatus being provided with a means to be able to place the honeycomb structure extending in length with progress of extrusion on the cradle with pressure contacting a cell opening end face of the honeycomb structure with the cradle under a pressure smaller than the compressive strength at the end face and then move the cradle at a speed capable of keeping the pressure contacting state and in the same direction as the lengthwise direction of the honeycomb structure, the pressure being determined by a load sensor which senses a load applied to the cradle.
A method for producing a honeycomb structure, characterized by extruding a material mainly composed of ceramics by an extruder in the gravity direction or a direction oblique at an angle of smaller than 30° with the gravity direction to form a honeycomb structure having a plurality of cells opening at an end face, molding the extruded honeycomb structure with pressure contacting the cell opening end face of the honeycomb structure with the cradle under a pressure smaller than the compressive strength at the end face, and cutting the honeycomb structure in the state of being pressure contacted with the cradle, the pressure being determined by a load sensor which senses a load applied to the cradle.
