An apparatus for producing a honeycomb structure having an extruder, at least one cradle and a cutting device comprising a small-gage wire for cutting the honeycomb structure and a notching member; said cradle is provided with a means capable of moving the honeycomb structure extruded from the extruder in the lengthwise direction of the honeycomb structure at nearly the same speed as the extrusion speed of the honeycomb structure, said cutting device is constructed so that the cutting small-gage wire is moved to the honeycomb structure side on the same plane as the plane of stretched small-gage wire, a cutting induction groove is formed on the outer peripheral side surface of the honeycomb structure by the notching member, and immediately thereafter the cutting small-gage wire is positioned in the induction groove, and the cutting small-gage wire is pressed into the honeycomb structure to cut the honeycomb structure.

An apparatus for producing a honeycomb structure having an extruder for continuously extruding a honeycomb structure in the gravity direction or in an oblique direction at an angle of smaller than 30° with the gravity direction, at least one cradle on which the honeycomb structure extruded is placed and which can move the honeycomb structure, and a movable cutting device, said cutting device comprising a frame body, a cutting small-gage wire stretched on the frame body, and a notching member provided with a position to notch the honeycomb structure on the plane including the stretched cutting small-gage wire, said cradle being provided with a means capable of placing thereon the honeycomb structure extruded from the extruder with its cell opening end face being supported by the cradle and capable of moving the honeycomb structure in this state in lengthwise direction at nearly the same speed as the extrusion speed in the lengthwise direction of the honeycomb structure, said cutting device being provided with a means capable of forming an cutting induction groove on the outer peripheral side surface of the honeycomb structure by the notching member by moving the stretched cutting small-gage wire to the honeycomb structure side on the plane including the cutting small-gage wire while moving the cutting device in the same direction and at nearly the same speed as the cradle nearly synchronously with the movement of the cradle in the lengthwise direction, capable of positioning the cutting small-gage wire in the induction groove immediately after formation of the induction groove, and capable of cutting the honeycomb structure by inserting the cutting small-gage wire as it is into the honeycomb structure.
A method for producing a honeycomb structure which comprises forming a cutting induction groove on the outer peripheral side surface of the honeycomb structure by a notching member while continuously extruding the honeycomb structure from an extruder and then cutting the honeycomb structure by inserting a cutting small-gage wire into the induction groove, characterized in that the honeycomb structure is extruded in the gravity direction or in an oblique direction at an angle of smaller than 30° with the gravity direction, and the formation of the induction groove by the notching member and the insertion of the small-gage wire into the induction groove are carried out at the same time.
