（２）各装置の位置関係
バックアップロール１２とダイ１４の位置関係について説明する。図１と図２に示すように、バックアップロール１２の回転軸１３の中心Ｏから垂線Ｓを降ろした場合に、その垂線Ｓは、ダイ１４の第１本体１６の第１塗工刃部３６の前面を通過する。これにより、第１塗工刃部３６の上面がバックアップロール１２の下周面と最も近接した位置となる。図２に示すように、吐出口４２から吐出した塗工液は、反時計回りに回転するバックアップロール１２によってウエブＷの表面に塗工される。そして、第１塗工刃部３６とバックアップロール１２を走行するウエブＷまでの間隔が塗工隙間となる。 (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.

次に、吐出口４２とダイ押圧部５８の位置関係について説明する。バックアップロール１２の回転軸１３の中心Ｏから降ろした垂線Ｓが、円柱型のダイ押圧部５８の中心を通過するように、ダイ押圧部５８を基部２０の下面に配している。 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）塗工装置１０の動作状態
次に、塗工装置１０の動作状態について図１～図４を参照して説明する。 (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.

まず、図１に示すように、ダイ１４の第１本体１６と第２本体１８にそれぞれ第１カバー７０と第２カバー９０を取り付け、塗工装置１０全体をカバーで覆う。 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.

図１に示すように、バックアップロール１２を反時計回りの方向に回転させ、下周面にあるウエブＷを後から前（上流から下流）に走行させる。 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).

バックアップロール１２の下方に配されたダイ１４の液溜め部２４には、不図示のポンプから供給管４８、供給口４６を経て塗工液が供給される。液溜め部２４に供給された塗工液は液通路４０から上昇し、吐出口４２から吐出される。吐出された塗工液は、バックアップロール１２の下周面を走行するウエブＷの表面に塗工される。このときの状態についてさらに詳しく説明する。 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.

まず、上ダイ１２の上部の短手方向の断面形状は、第１傾斜面２２と第２傾斜面２６によって上部に向かって狭くなるように形成され、さらに上端部は第１塗工刃部３６と第２塗工刃部３８の部分が、上方に突き出たリップ型となっている。そして、そのリップ型の上端で塗工を行うことができる。しかし、ここで問題なのは、バックアップロール１０の下周面は円弧であり、第１塗工刃部３６の上面と第２塗工刃部３８の上面は、平面形状であるので、たとえ同じ高さでも第１塗工刃部３６の上面と第２塗工刃部３８の上面の全てで同じ塗工圧、塗工厚で塗工を行うことができないことである。 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.

そのため本実施形態では、第２塗工刃部３８の下流にある第１塗工刃部３６の上面の前部を、回転軸１３の中心Ｏの真下に位置させている。このようにすると、第１塗工刃部３６の上面の前部とバックアップロール１２の下周面との間隔が最も接近し、この接近した位置が最も塗工圧がかかることになる。そのため、この最も塗工圧の高い位置で塗工する。すなわち、第１塗工刃部３６の上面の前部とバックアップロール１２の下周面との間隔が、塗工間隔となり、塗工厚が決定される。特に、第１塗工刃部３６の上面と第２塗工刃部３８の上面を同じ高さに設定されているため、図４に示すように、ウエブＷがスムーズに走行でき、かつ、第２塗工刃部３８の上面の後部とバックアップロール１２の下周面との間隔をＡ、第２塗工刃部３８の上面の前部と下周面との間隔をＢ、第１塗工刃部３６の上面の後部と下周面との間隔をＣ、第１塗工刃部３６の上面の後部と下周面との間隔をＤとすると、Ａ＞Ｂ＞Ｃ＞Ｄとなり、ウエブＷにかかる塗工圧が次第に上昇し、Ｄの最も塗工圧が高い位置で塗工できる。 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.

一方、吐出口４２から吐出される塗工液の圧力によって、ダイ１４の上端部が、左右方向の中央ほど下方に湾曲する。この湾曲を防止するため、ベンド装置８のダイ押圧部５８によって、ダイ１４の基部２０の下面を押圧する。本実施形態では、図２に示すように、このダイ押圧部５８の押圧位置は、左右方向の中央であって、かつ、前後方向においてはバックアップロール１２の回転軸１３の中心Ｏの真下の位置としている。なぜ、バックアップロール１２の回転軸１３の中心Ｏの真下の位置を押圧するかを説明する。上記したように、バックアップロール１２の回転軸１３の中心Ｏの真下の位置に対応する第１塗工刃部３６の上面の前部とバックアップロール１２の下周面との間隔が最も接近し、この接近した位置が最も塗工圧がかかる。そのため、前後方向においてはこの部分で湾曲が最も発生しやすくなる。そこで本実施形態では、前後方向においてバックアップロール１２の回転軸１３の中心Ｏ（第１塗工刃部３６の上面の前部）の真下の位置を押圧して、湾曲を防止している。 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.

また、基部２０と第１本体１６をベンドさせると、第１本体１６に固定された第２本体１８も同時にベンドさせることができる。 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）効果
本実施形態によれば、ダイ１４を第１カバー７０と第２カバー９０によって覆っているため、吐出口４２から塗工液が漏れ出ても、ダイ１４の第１傾斜面２２、第２傾斜面２６を流れた後、第１カバー７０と第２カバー９０を流れて床まで垂れるため、ダイ１４の下部やベンド装置８、基台６が汚れない。 (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.

また、第１カバー７０と第２カバー９０は、第１両面接着テープと第２両面接着テープによって第１取り付け部材６０と第２取り付け部材８０に取り付けられているため、汚れた場合であっても簡単に交換できる。 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.

第１カバー７０と第２カバー９０は、無色透明であるためカバー内部の装置の状態を作業員が目視できる。 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.

第１カバー７０には、切り込み７２と孔７４が設けられているため、第１本体１６の上から第１カバー７０を被した場合であっても、この切り込み７２を通じて孔７４に供給管４８が至り、供給管４８の部分が障害にならずに第１カバー７０を第１本体１６に被せることができる。 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.

第１取り付け面６２が、第１傾斜面２２の第１凹部７６に固定され、第２取り付け面８２が、第２傾斜面２６の第２凹部９２に固定されているため、第１傾斜面２２と第２傾斜面２６には、第１取り付け面６２と第２取り付け面８２による凹凸がなく、塗工液が第１カバー７０と第２カバー９０に流れやすい。 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.
