(2) Positional Relationship of Each Device The positional relationship between the backup roll 12 and the die 14 will be described. As shown in FIGS. 1 and 2, when the vertical line S is drawn from the center O of the rotation shaft 13 of the backup roll 12, the vertical line S is the first coating blade portion 36 of the first main body 16 of the die 14. Pass the front. As a result, the upper surface of the first coating blade portion 36 becomes the position closest to the lower peripheral surface of the backup roll 12. As shown in FIG. 2, the coating liquid discharged from the discharge port 42 is applied to the surface of the web W by the backup roll 12 that rotates counterclockwise. Then, the distance between the first coating blade portion 36 and the web W traveling on the backup roll 12 is the coating gap.

Next, the positional relationship between the discharge port 42 and the die pressing portion 58 will be described. The die pressing portion 58 is arranged on the lower surface of the base 20 so that the vertical line S drawn from the center O of the rotation shaft 13 of the backup roll 12 passes through the center of the cylindrical die pressing portion 58.

(3) Operating State of Coating Device 10 Next, the operating state of the coating device 10 will be described with reference to FIGS. 1 to 4.

First, as shown in FIG. 1, the first cover 70 and the second cover 90 are attached to the first main body 16 and the second main body 18 of the die 14, respectively, and the entire coating device 10 is covered with the cover.

As shown in FIG. 1, the backup roll 12 is rotated in the counterclockwise direction, and the web W on the lower peripheral surface is run from the rear to the front (upstream to downstream).

The coating liquid is supplied from a pump (not shown) to the liquid storage portion 24 of the die 14 arranged below the backup roll 12 via the supply pipe 48 and the supply port 46. The coating liquid supplied to the liquid reservoir 24 rises from the liquid passage 40 and is discharged from the discharge port 42. The discharged coating liquid is applied to the surface of the web W running on the lower peripheral surface of the backup roll 12. The state at this time will be described in more detail.

First, the cross-sectional shape of the upper part of the upper die 12 in the lateral direction is formed so as to be narrowed toward the upper part by the first inclined surface 22 and the second inclined surface 26, and the upper end portion is formed by the first coating blade portion 36. And the part of the second coating blade portion 38 is a lip type protruding upward. Then, coating can be performed at the upper end of the lip mold. However, the problem here is that the lower peripheral surface of the backup roll 10 is an arc, and the upper surface of the first coating blade portion 36 and the upper surface of the second coating blade portion 38 have a planar shape, so that they have the same height. However, it is not possible to perform coating on the upper surface of the first coating blade portion 36 and the upper surface of the second coating blade portion 38 with the same coating pressure and coating thickness.

Therefore, in the present embodiment, the front portion of the upper surface of the first coating blade portion 36 located downstream of the second coating blade portion 38 is positioned directly below the center O of the rotating shaft 13. In this way, the distance between the front portion of the upper surface of the first coating blade portion 36 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 the highest. That is, the distance between the front portion of the upper surface of the first coating blade portion 36 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 coating blade portion 36 and the upper surface of the second coating blade portion 38 are set to the same height, the web W can run smoothly and the first coating blade portion 38 can be run smoothly as shown in FIG. 2 The distance between the rear part of the upper surface of the coating blade 38 and the lower peripheral surface of the backup roll 12 is A, the distance between the front part of the upper surface of the second coating blade 38 and the lower peripheral surface is B, and the first coating. Assuming that the distance between the rear portion of the upper surface of the blade portion 36 and the lower peripheral surface is C and the distance between the rear portion of the upper surface of the first coating blade portion 36 and the lower peripheral surface is D, A> B> C> D and the web. The coating pressure applied to W gradually increases, and coating can be performed at the position where the coating pressure of D is the highest.

On the other hand, due to the pressure of the coating liquid discharged from the discharge port 42, the upper end portion of the die 14 is curved downward toward the center in the left-right direction. In order to prevent this bending, the lower surface of the base 20 of the die 14 is pressed by the die pressing portion 58 of the bend device 8. In the present embodiment, as shown in FIG. 2, the pressing position of the die pressing portion 58 is the center in the left-right direction and directly below the center O of the rotation shaft 13 of the backup roll 12 in the front-rear direction. It is supposed to be. The reason why the position just below the center O of the rotation shaft 13 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 coating blade portion 36 corresponding to the position directly below the center O of the rotation shaft 13 of the backup roll 12 and the lower peripheral surface of the backup roll 12 is closest. The coating pressure is most applied at this close position. 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 coating blade portion 36) of the rotation shaft 13 of the backup roll 12 is pressed in the front-rear direction to prevent bending.

Further, when the base 20 and the first main body 16 are bent, the second main body 18 fixed to the first main body 16 can also be bent at the same time.

(4) Effect According to the present embodiment, since the die 14 is covered with the first cover 70 and the second cover 90, even if the coating liquid leaks from the discharge port 42, the first inclined surface 22 of the die 14 After flowing through the second inclined surface 26, the first cover 70 and the second cover 90 flow and hang down to the floor, so that the lower part of the die 14, the bend device 8, and the base 6 are not contaminated.

Further, since the first cover 70 and the second cover 90 are attached to the first attachment member 60 and the second attachment member 80 by the first double-sided adhesive tape and the second double-sided adhesive tape, even if they become dirty. Easy to replace.

Since the first cover 70 and the second cover 90 are colorless and transparent, the operator can visually check the state of the device inside the cover.

Since the first cover 70 is provided with a notch 72 and a hole 74, the supply pipe 48 is provided in the hole 74 through the notch 72 even when the first cover 70 is covered from above the first main body 16. The first cover 70 can be put on the first main body 16 without the portion of the supply pipe 48 becoming an obstacle.

Since the first mounting surface 62 is fixed to the first recess 76 of the first inclined surface 22, and the second mounting surface 82 is fixed to the second recess 92 of the second inclined surface 26, the first inclined surface 22 The second inclined surface 26 has no unevenness due to the first mounting surface 62 and the second mounting surface 82, and the coating liquid easily flows to the first cover 70 and the second cover 90.
