Patent ID: 6994816

Claim:
An apparatus for producing a honeycomb structure, the apparatus comprising: an extruder that in operation continuously extrudes a honeycomb structure in at least one of a gravity direction or an oblique direction at an angle of smaller than 30° with the gravity direction; at least one cradle on which the extruded honeycomb structure is supported and which can move the honeycomb structure; and a movable cutting device, the cutting device further comprising: a frame body; a cutting small-gage wire stretched on the frame body; and a separate notching member provided at a position to notch the honeycomb structure on a plane including the stretched cutting small-gage wire, wherein the cradle supports a cell opening end face of the honeycomb structure, and the cradle moves the honeycomb structure in the supported state in a lengthwise direction at substantially a same speed as an extrusion speed in the lengthwise direction of the honeycomb structure, and the cutting device is used to form a cutting induction groove on an outer peripheral side surface of the honeycomb structure by the separate notching member while the cutting device is moved synchronously with the movement of the cradle in the lengthwise direction, and the cutting device is moved to position the cutting small-gage wire in the cutting induction groove after formation of the cutting induction groove, and the honeycomb structure is cut by inserting the cutting small-gage wire into the honeycomb structure.
