Then, the first main body 22, the first shim 70, and the intermediate main body 24 are integrally fixed by the plurality of first fastening bolts 90. In this case, the intermediate body 24 is located above the base 20.

Next, the second main body 26 is arranged on the intermediate main body 24 with the second shim 80 interposed therebetween. At this time, since the second main body 26 is provided with a pair of left and right handles 68, the operator can easily hold the second shim 80 by holding the handles 68. Then, the second main body 26, the second shim 80, and the intermediate main body 24 are integrally fixed by the plurality of second fastening bolts 100. As a result, the first main body 22, the intermediate main body 24, and the second main body 26 are integrally fixed with the first shim 70 and the second shim 80 sandwiched between them.

Next, the first fastening bolt 90 and the second fastening bolt 100 are slightly loosened, and the first pressing bolt 42, the intermediate pressing bolt 56, and the second pressing bolt 58 are moved up and down to move the first cutting edge 34, the intermediate cutting edge 40, and the second. 2 Adjust so that the cutting edge 64 is on the same surface, that is, horizontally as shown in FIG.

It is formed. A second liquid passage 124 is formed between the intermediate main body 24 and the second main body 26 above the second liquid reservoir 62, and a slit-shaped second discharge port 126 is formed at the upper end thereof.

(5) Positional Relationship between Backup Roll 12, Laminated Die 14, and Bend Device 16 The positional relationship between the backup roll 12, the laminated die 14, and the bend device 16 will be described with reference to FIGS. 1, 5, and 6.

As shown in FIG. 6, the front portion of the upper surface of the first cutting edge 34 of the first main body 22 of the laminated die 14 is positioned directly below the center O of the rotating shaft 18. In this way, the distance between the front portion of the upper surface of the first cutting edge 34 and the lower peripheral surface of the backup roll 12 is closest, and the coating pressure is applied most at this close position. Therefore, coating is performed at the position where the coating pressure is highest. That is, the distance between the front portion of the upper surface of the first cutting edge 34 and the lower peripheral surface of the backup roll 12 becomes the coating interval, and the coating thickness is determined. In particular, since the upper surface of the first cutting edge 34 and the upper surface of the second cutting edge 64 are set to the same height, the web W runs smoothly. Further, as shown in FIG. 6, the distance between the rear portion of the upper surface of the second cutting edge 64 and the lower peripheral surface of the backup roll 12 is A, and the distance between the front portion of the upper surface of the second cutting edge 64 and the lower peripheral surface of the backup roll 12 The distance is B, the distance between the rear part of the upper surface of the intermediate cutting edge 40 and the lower peripheral surface is C, the distance between the front part and the lower peripheral surface of the upper surface of the intermediate cutting edge 40 is D, and the distance between the rear part and the lower peripheral surface of the upper surface of the first cutting edge 34. Assuming that the distance from the surface is E and the distance between the front part of the upper surface of the first cutting edge 34 and the lower peripheral surface is F, A> B> C> D> E> F, and the coating pressure applied to the web W gradually increases. It rises and can be coated at the position where the coating pressure of F is the highest.

On the other hand, due to the pressure of the first coating liquid and the second coating liquid discharged from the first discharge port 122 and the second discharge port 126, the upper end portion of the laminated die 14 is curved downward toward the center in the left-right direction. In order to prevent this bending, the die pressing portion 114 of the bend device 16 presses the lower surface of the base 20 of the laminated die 14. In the present embodiment, as shown in FIG. 2, the pressing position of the die pressing portion 114 is at the center in the left-right direction, and as shown in FIG. 5, the rotation axis 18 of the backup roll 12 is in the front-rear direction. It is located directly below the center O of. The reason why the position just below the center O of the rotation shaft 18 of the backup roll 12 is pressed will be described. As described above, the distance between the front portion of the upper surface of the first cutting edge 34 corresponding to the position directly below the center O of the rotation shaft 18 of the backup roll 12 and the lower peripheral surface of the backup roll 12 is the closest, and the distance is close to this. The position is where the coating pressure is the highest. Therefore, in the front-rear direction, bending is most likely to occur in this portion. Therefore, in the present embodiment, the position directly below the center O (the front portion of the upper surface of the first cutting edge 34) of the rotation shaft 18 of the backup roll 12 is pressed in the front-rear direction to prevent bending.

Further, when the base portion 20 and the first main body 22 are bent, the intermediate main body and the second main body fixed to the first main body 22 can also be bent at the same time.

(6) Cutting edge adjustment method When the coating liquid is applied to two layers in the coating device 10, the upper surface of the first cutting edge 34, the upper surface of the intermediate cutting edge 40, and the upper surface of the second cutting edge 64 as shown in FIG.

This position of the stylus 164 is the height of the reference position. The intermediate cutting edge 40 and the second cutting edge 64 are lowered to positions lower than the reference position. As a result, the adjustment of the first cutting edge 34 is not hindered.

Fourth, the intermediate main body 24 is raised by adjusting the first pressing bolt 42 provided on the first main body 22, and the stylus 164 at the reference position is shown on the alternate long and short dash line in FIG. The intermediate cutting edge 40 is brought into contact with the stylus 164 and pushed up as it is. The second cutting edge 64 is lowered to a position lower than this reference position. As a result, the adjustment of the intermediate cutting edge 40 is not hindered.

Fifth, the first pressing bolt 42 is adjusted to lower the intermediate main body 24 as shown by the solid line in FIG. 11, and at the same time, the stylus 164 is lowered to reach the reference position. To fix.

Sixth, by adjusting the second pressing bolt 58 on the support protrusion 46, the second main body 26 is raised as shown by the alternate long and short dash line in FIG. The two cutting edges 64 are brought into contact with each other, and the stylus 164 is pushed up as it is.

Seventh, the second pressing bolt 58 is adjusted to lower the second main body 26, and the stylus 164 is lowered at the same time, at the position where the reference position is reached as shown by the two-dot chain line in FIG. The second main body 26 is fixed.

Eighth, as shown in FIG. 13, the first cutting edge 34, the intermediate cutting edge 40, and the second cutting edge 64 can be fixed on the same surface. After that, the cutting edge adjusting device 150 is removed from the first main body 22, and the backup roll 12 is moved to a predetermined position. As a result, the web W can be coated.

(7) Operating State of Coating Device 10 The coating state of the coating device 10 will be described. In FIG. 1, the web W advances the lower peripheral surface of the backup roll 12 (runs from right to left in FIG. 1).

First, the first coating liquid is supplied to the first liquid reservoir 32 from the first supply port 36. Further, the second coating liquid is supplied to the second liquid reservoir 62 from the second supply port 66.

Next, the second coating liquid is discharged from the second liquid reservoir 62 through the second liquid passage 124 and the second discharge port 126, and is coated on the advancing web W.

Next, the first coating liquid is discharged from the first liquid reservoir 32 through the first liquid passage 120 and from the first discharge port 122. Then, the first coating liquid is laminated and coated on the second coating liquid coated on the web W that advances further.
