An apparatus of the present invention is a continuous extrusion forming apparatus comprising: a screw which carries a forming raw material in the horizontal direction, the screw being built in the screw part; and a mouth piece structure for extrusion forming, which is provided on the downstream side of a screw part, wherein the mouth piece structure has a horizontal channel for extruding the forming raw material flowing in from the screw part in the horizontal direction, an extrusion channel orthogonal to the horizontal channel, and an extrusion port provided at a tip end of the extrusion channel, and wherein a mouth piece structure holder which holds the mouth piece structure is provided with a turning means which freely changes the opening direction of the extrusion port between the horizontal direction and a floor facing direction.

Continuous extrusion forming apparatus

An assembling method for an assembly is provided: the assembly comprising a cell structure () housed and held in a metal vessel () via a compressible material having a cushioning property () by arranging it between outer periphery of the structure () and the vessel () in a compressed state with applying a mounting pressure to the structure () via the material () to hold the structure () in the vessel (). Information regarding outside dimension of the structure () and/or inside dimension of the vessel () being marked on their surfaces prior to the start of assembly, and the information is read, and a cell structure () and a metal vessel () are selected based on read information in assembly to achieve a proper holding condition therebetween. Regardless of variations in external dimension of the structure, etc. constituting the assembly, the minimization thereof, and proper holding state may be achieved easily without causing a fracture of the structure, etc.

Assembling method using marked information and assembly assembled by said assembling method

This is directed to a processing method for carrying a cell structure () with a catalytic component. Information about a mass of the cell structure () is displayed on the surface thereof prior to the initiation of a carrying process, and in the carrying process, the information is read and the cell structure () is carried with an appropriate amount of the catalytic component on the basis of the information. When cell structures are processed for carrying thereon a catalytic component, each cell structure can carry an appropriate amount of the catalytic component in accordance with the mass of the cell structure, even if there is a variation in the masses of the cell structures.

Processing method utilizing display information for carrying a cell structure with a catalytic component

An assembling method for assembling an assembly by combining a plurality of mating members with each other, wherein inherent information regarding dimensions of individual members, which is necessary for the combination of members, has been marked on the member surface prior to the start of an assembling process, the information marked on the member is read in the assembling process, and members having a dimension that meets a proper combining condition are selected based on the information. An individual member and inherent information regarding the dimension of members can be handled integrally, when the mating members are combined with each other, members having a dimension that meets a proper combining condition are selected, and when the member is processed so as to correspond to the property thereof, proper processing corresponding to the inherent properties of each member can be performed easily and surely without troublesome work.

Assembling method using marked information

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.

Equipment and method for manufacturing honeycomb structural body

A method for assembling a cell structure in a metal vessel, including reading information as indicia located on a surface of a compressible material having a cushioning property, the information regarding the thickness and/or bulk density of the compressible material; selecting a cell structure, a metal vessel, and a compressible material which, when assembled as a cell structure housed in a metal vessel, have a proper holding condition based on the read information; assembling the selected cell structure in the selected metal vessel via the selected compressible material, the compressible material being located in a compressed state between an outer periphery of the cell structure and the metal vessel to hold the selected cell structure in the selected metal vessel.

Assembly method using marked information and assembly assembled by said assembling method

A method of manufacturing ceramic bodies having a construction such that cells are alternately sealed at one but not both end surfaces of a ceramic honeycomb structural body by filling a sealing slurry into predetermined cells at both end surfaces of a ceramic honeycomb formed body and sintering the ceramic honeycomb formed body, is performed by: forming a mask for respective ceramic honeycomb formed bodies by arranging a sheet on an end surface of the ceramic honeycomb formed body and piercing holes in the sheet at positions corresponding to the predetermined cells; immersing an end portion of the ceramic honeycomb formed body to which the mask is arranged into the sealing slurry; and filling the sealing slurry into the cells through the holes pierced in the mask.

Method of manufacturing ceramic bodies

A method of producing a ceramic body having a construction such that cells are plugged alternately at both end faces of a ceramic honeycomb structural body by filling a plugging slurry into predetermined cells at both end faces of a ceramic honeycomb formed body, having the steps of: filling a plugging material for mask into the cells to be opened at one end face of the ceramic honeycomb formed body; immersing the end face, to which the plugging material for mask is filled, into a plugging slurry; and drying and sintering the ceramic honeycomb formed body while the plugging material for mask is removed during a drying step or a sintering step.
