摘要： PURPOSE:To obtain the coiling state of stable quality by moving a reel shaft which has the cross section of C-shape in the lateral direction of foil, inserting the end of foil in the inside part of the reel shaft and coiling. CONSTITUTION:By use of the reel shaft 1 with a cross section of C-shape which has an opening part 1a in the longitudinal direction, the end of a piled metallic foil 4 which is made by piling a flat foil 2 and a corrugated foil 3 is inserted inside the opening part 1a of the reel shaft 1 and the piled metallic foil 4 is coiled to a desired diameter by revolving the reel shaft 1 about the axis and a columnar honeycomb body is manufactured. It is desirable that the end of the foil 4 which is inserted inside the opening part 1a of the reel shaft 1 is provided with folds 4a such as zigzag so as not to easily separate after inserting.

摘要： PURPOSE:To reduce the production cost of a metallic carrier by inserting a honeycomb body which is alternately wound and superposed with corrugated foil and flat foil on each other and has the corrugated foil on its outermost periphery into a metallic outside cylinder and joining the inside of this honeycomb body and the outside cylinder by a binder. CONSTITUTION:The cylindrical honeycomb body 1 is produced by superposing and spirally winding the corrugated foil 3 having the peak parts of waveforms exhibiting a pseudo sinusoidal waveform and the flat foil 3. The outer periphery of such honeycomb body is composed of the corrugated foil 2. Such honeycomb body is press fitted into the outside cylinder 4. The peak parts of the waveforms of the corrugated foil 2 are formed to a shape having a curvature of radius R=0.2 to 0.6m. Namely, the press fitting of the honeycomb body 1 at a wide press fitting margin is possible at the time of press fitting the honeycomb body into the outside cylinder 4 if the radius of curvature R is in this range. Next, the ends of the honeycomb body 1 are made flush and are brought into contact with sponge impregnated with a binder liquid to simultaneously supply the binders necessary for joining the outside cylinder 4 and the honeycomb body 1 and joining the honeycomb body 1 itself. Powder solder is sprayed by a solder spraying device to the outside cylinder 4 and the honeycomb body 1 which are then subjected to vacuum brazing treatment.

摘要： PURPOSE:To improve productivity and eliminate low yield due to cutting by controlling outside diameter or outside peripheral length completely so as to be within a prescribed target. CONSTITUTION:The tail end of a wavy foil 2 is detected at a prescribed position in the course of winding, and the outside peripheral dimension of a honeycomb structure 3 is measure at the time of detection. Based on a difference between the target value and the measured value of the outside peripheral dimension, the subsequent winding tension of a flat foil 1 is controlled. It is desirable that the winding tension should be controlled by detecting the tail end at plural prescribed positions.

摘要： PURPOSE:To prevent the protrusion of a honeycomb body from an outside cylinder by winding a flat plate and corrugated foil around an axial center having a radius of (the straight part length/circle ratio of after forming of the honeycomb body) until the thickness attains (the radius of the arc part of the honeycomb body + allowance for press fitting), removing the axial center, crushing the honeycomb body to an elliptic shape until the spaces come into tight contact with each other, and press fitting the honeycomb body into the outside cylinder. CONSTITUTION:The flat foil and corrugated foil are wound around the axial center having the radius of the straight part length/circle ratio) until the thickness attains (the radius of the arc part of the honeycomb body + allowance for press fitting) at the time of forming the honeycomb body 5 by winding the flat foil and the corrugated foil. After the axial center is removed, the honeycomb body is crushed to the elliptic shape until the spaces come into tight contact with each other. The honeycomb body is thereafter press fitted into the outside cylinder. Consequently, the the metal carrier of a lace track type which prevents the protrusion of the honeycomb body from the outside cylinder and lessens the disturbance of the honeycomb part is efficiency produced.
