Description of the invention: [Technical field of the invention] The present invention relates to a two-liquid curing type. Solvent-free type 2 201200247 涂布 A coating device for laminating products by bonding sheet-like feed materials (web) as a substrate to each other. E. [Prior Art] A method of applying a solventless type adhesive to a laminate web using a plurality of coating rolls (for example, refer to Patent Document 1), and coating with a first mold a method for producing a composite film by coating a first component of a solventless adhesive on a film, and applying a second component of a solventless (tetra) mixture to a film by a second die coater (for example, refer to Patent Document 2) [Patent Document 1] Patent Document 1: Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. In the method described, τ is supplied to the barrier dam 110 as a two-component solvent-free binder constituting the two-liquid curing U-type, for example, the main agent J-groove 114 is supplied from the tank 113, respectively. Supplying a curing agent and bringing the two into contact, and the dot-forming agent formed by the contact is supplied between the pair of rolls of the first roll 101 and the second roll 102, and 4, and the first roll from one of them 102 supplies the second roller 103' to be supplied again . . . I the second affinity between the fourth roller 104 abutting the third roller 103, the soil material 1 0 5 , and then the substrate having the drilling agent 1 0 5 to contain m The laminating portion 109 is transported to 201200247, and the other substrate 106 conveyed by the other conveying line to the laminating portion ι 9 and the substrate 1b having the above-mentioned adhesive are pressure-bonded by the laminating portion 109, thereby making a paste. A laminate product comprising two substrates. The base material and the curing agent of the adhesive used in the bonding are not cured when they are separated, but can be cured after a specified time after contact between the two. However, the method of the above-mentioned Patent Document 丨 has a problem that when the adhesive is applied to the substrate 1〇5 conveyed between the third roll 103 and the fourth roll 1〇4, the cause cannot be avoided. The coating liquid is torn on the side of the substrate i 〇 5 and the side of the third roll i 〇 3 to cause the coated surface to have an orange peel shape. In particular, when a binder having a high molecular weight is used for improving heat resistance, coating is performed. The increase in viscosity causes the orange peel to become more pronounced. In addition, if the transfer speed is increased in this case, it will lead. In the case of the adhesion, the thickness of the adhesive is reduced, and if the viscosity of the adhesive is lowered to prevent the coating surface from being rough, the initial adhesive force is lowered to cause a poor adhesion such as a tunnel. When the apparatus is stopped in order to change the magnitude of the laminate product or the like, the adhesive is accumulated in a passage in the inside of the barrier sheet due to the contact of the two layers of the barrier sheet 110, and thus the amplitude and size of the laminate product are changed. In addition, when the coating is carried out by the roll coating method disclosed in the above-mentioned Patent Document i, if the viscosity of the coating liquid is low, the coating liquid applied by the roll coating cannot be lifted, so that it is difficult to sufficiently ensure the progress. Since the amount of the liquid applied to the material is insufficient, there is a problem that a coating liquid having a liquid viscosity of, for example, 500 Pas (cps) or less cannot be used. On the other hand, the method of Patent Document 2 has the following problems. That is, after coating the first layer containing the first component ^^^, x on the 2012 film of 201200247, and applying the second layer containing the first component to the film, ^^^^^, the first layer The outer surface (two-liquid contact surface) is temporarily exposed. The road is in the working milk' and thus it is possible to mix air. In addition, since the second layer is too close to the coating, the coating is thin, so when the die lip approaches the coated surface, sometimes the coating liquid of the layer, if the lip of the first layer (llp) is scraped The first addition... scraping off the coating liquid results in a rough coating surface. In addition, it is usually difficult to change the coating twist frequently when making a laminate product. Therefore, when there are two die coating heads, there are the following difficulties when the two heads are used. The two-die coating head is replaced with a size of I ^ ^ ruler coating size. This preparation takes a long time. Means for Replacing the Problem The present invention is directed to solving the problems in the technique of the present invention, and the object thereof is to provide a coating apparatus for fabricating M m & * Shaw-liquid-curing solvent-free adhesive « w exhibits smoothness when laminated. fT inter-agitated operation" and can be applied to the coated surface protective agent type: two: ^ for the use of two-liquid curing type of non-dissolving material...:=:= cloth: yes: send a 盥, f a pair of slit-shaped outlets, and a plurality of outlets of the pair of outlets, upwardly, a pair of inlets that are connected to each other, and a supplier--input of the inlet - the inlet is supplied to form the above-mentioned stick The sputum, and the first supply portion, supply a first liquid for forming the above-mentioned adhesive by contacting the first one, the scorpion liquid, to the other inlet of the pair of inlets, wherein the mold-coated soil cloth The above-mentioned outlet of the machine is disposed adjacent to the feed material conveying direction of the line 201200247, and the first liquid and the second liquid just from the above one make the above ig J. Immediately after the exit, the first liquid and the second liquid are discharged from the two outlets of the feed material · conveyed by the above-described structure 崁峒 conveyance line, and the second liquid and the second liquid are discharged. The direction of the next. Yu Qiu, the shape and ., / / phantom exits the liquid discharged in the overlap , the liquid discharged from the outlet on the upstream side of the 矣°, the two liquids are in contact, and the material of the feed material of the spotting agent formed by the contact is formed, thereby producing a laminate product, a feed, and a Since the first liquid and the second liquid are supplied between the two "outlet" of the die coater, even if the operation is temporarily stopped for the replacement of the size, the work is performed on the inside of the die coater and the A coating. The first supply unit and the second supply of the first liquid and the second liquid are respectively supplied, and the two liquids in the upper portion are not in contact with each other, so that there is no solidification in the inside of the machine: . Further, since the liquid is applied to the feed material from the two outlets of the die coater, the coating liquid is not torn by the feed material and the roll as in the conventional example of Fig. 8, and the coated surface can be kept smooth. In addition, wrinkles are also prevented. In the coating apparatus, the outlet on the upstream side in the conveyance direction is for discharging the outlet on the downstream side of the first liquid and the second liquid, and the discharge amount is small. According to this configuration, a layer of the first liquid having a large discharge amount and a relatively large thickness can be formed on the feed material, and then a layer of the second liquid having a small discharge amount and a small amount can be formed, whereby the incorporation of air can be suppressed. In other words, a thick first liquid layer is formed on the outlet side on the upstream side in the conveying direction of the feed material to block the gap between the die coater and the feed material 6 in the upstream direction of the 201200247 direction. In the case where the second liquid layer is formed, it is difficult to mix in the coating apparatus, and the upstream side of the transport direction is used to discharge a high degree of dryness in the first liquid and the second liquid. The downstream side and the outlet are used to discharge the lower viscosity side. According to the structure,
、材料上先形成粘度較高的第一液的層而使第一層處於 穩定狀態，麸播交且BM 的層。”、 適“也層疊形絲度較低的第二液 s塗布裝置中’上述搬送方向的上游側的出口用於 述第&及上述第二液中粘度較低的-方，下游側的出 用於排出而粘度較尚的一方。根據該結構，可使塗布液 ί進、。材料的潤濕性變得良好。i處，潤濕性是指將塗布 句勻地丄布在整個進給材料上時的塗布的容易度，通常 粘度較低的塗布液的潤濕性比粘度較高的塗布液好。因 此在形成兩層塗布層時，對與進給材料接觸的側（先） ^布低ϋ度的液體’這樣可提高塗布液對進給材料的爛濕 性。 在該塗布裝置中，在設置在上述搬送方向的上游側的 出口的上游側設有真空腔室。根據該結構，可通過真空腔 室抑制空氣混入進給材料塗布的液體中。 在該塗布裝置中’較為理想的是排出上述第一液的上 述出口及排出上述第二液的上述出口的各模刃口 （ die edge )均以1 〇〇 y m以下的曲率半徑而形成。根據該結構， 由於模刃口比較鋒利，因此可以使塗布面保持平滑以防止 201200247 氣泡的混入。尤並θ , ㈣1… 氣性或透氣性小的進給材 科進盯層壓時較為有效。此外，由於形成得鋒利的模刃口 位於進給材枓離開模塗布機的部⑯，因此粘合劑的斷開變 侍良好’從而抑制粘合劑流向模塗布機一側。 此外’作為上述模刀口的曲率半徑較為理想的是為 30" m以上。其理由是，雖然在塗布上無任何問題，但如 果曲率半徑過小則會在加工時產生模刀口容易缺損等問 題。 在該土布裝置中’在上述第一供應部及上述第二供應 部中分別設置有調節液體溫度的溫度調節部。根據該結 構’當苐-液與第二液各自的粘度不同時，可通過調節一 方的液體溫度或兩方的液體溫度而使兩液體的粘度成為相 同程度，由此具有伴隨兩液體的接觸所進行的混合變得容 易的優點。 在該塗布裝置中，上述模塗布機在各出口的狹縫長度 方向的兩端部分別具有調節狹縫長度的調節部，各調節部 包括·狹縫長度調節片’利用與上述出口連接的狹縫及與 該狭縫連接的液體積存處，能夠在上述狹縫長度方向上滑 動’具有在上述狹縫内移動的狹縫移動部及在上述液體積 存處的一部分内移動的液體積存處移動部；以及固定片， 沿上述狹縫長度方向在上述液體積存處的剩餘空間内移動 以固定上述狹縫長度調節片，上述固定片具有傾斜的擠壓 面’通過從上述狹縫長度方向的外側向内側壓入而將上述 狹縫長度調節片的上述液體積存處移動部擠壓到上述液體 8 201200247 積存處。 、根據該結構，在調節狹縫長度（塗布幅度）時，可通 過使固疋片朝著從狹縫長度方向的内側向外側的拔出方向 移動’解除楔形（taper)的固以將狹縫長度調節片的液體 積存處移動部擠壓到液體積存處的力，從而使狹縫長度調 即片的固定鬆他。然後’使狹縫長度調節片沿著狹縫長摩 方向滑動，在狹縫長度調節片移動到指定位置之後，從狹 縫長度方向的外側向内侧壓入固定片。伴隨此固定片的 傾斜擠壓面向狹縫側擠壓狹縫長度調節片，由此固定片可 字狹縫長度調㊅片的液體積存處移動部擠壓到液體積存 處’並使狹縫長度調節片㈣。因此，通過在狹縫狀出α 的兩側將狹縫長度調節片分別固定在指定位i，可簡單地 調節狹縫長度。此外，隸固定片及狹縫長度調節片沿狹 縫長度方向移動，但因能夠防止固定片&狹縫長度調節片 的液體積存處移動部從液體積存處滑動脫落，所以作業性 大幅提高。另外，通過在狹缝長度調節片上也預先形成與 固定片的擠壓面反向的傾斜的被擠壓面，可減小狹縫長度 調節片與固定片的接合面的間隙，由此可進一步提高密封 性。 在該塗布裝置中，較為理想的是，將塗布在上述進給 材料上的由上述第一液形成的層與由上述第二液形成的層 的合計層厚設為0.7/ζιη以上以下。即，通過將該合 计層厚設為0. 7 // m以上，可確保兩個進給材料的粘合所需 要的粘合力。另一方面，通過將合計層厚設為以下， 201200247 °在可吸收因在進給材料上實施印刷而形成的凹凸的情 況下削減多餘的層厚並且進行粘合。 在該塗布裝置中’在上述進給材料的搬送線的與上述 模塗布機相對置的位置還設置有援助輥，上述援助輥為橡 述一對出口中位於搬送方向下游側的出口的 下游側的模頭的頂端面部抵接於上述援助棍的圓周面。根 據該結構’即便援助輥的真圓度不精#，也彳通過使該援 輥彈性變形，而有效地防止發生在其旋轉時模頭的頂端 面。Ρ與援助輥的圆周面之間形成較大的間隙，或者模頭的 頂端面部牢固地壓接在援助親的圓周面上而導致塗布液的 膜厚不足的情況，因而可均勾地設定塗布在上述進給材料 上的塗布液的膜厚。 發明效果 根據本發明的上述結構，由於從模塗布機的兩個入口 到各出口分別分開供應第一液與第二液1此即便為了變 更塗布幅度而暫時停止作業，也由於 兴土布機的内部及 對其分別供應第一液及第二液的第一 示t、應。ρ及第二供應部 中兩液不會接觸，因而其内部不會存在固化 的姑合劍，可 簡化準備作業。此外，由於是從模塗 w伐的兩個出口射進

having a higher viscosity to make the first layer in a stable state, and the bran is broadcasted to the layer of BM. In the second liquid s coating apparatus having a low degree of laminated filamentity, the outlet on the upstream side in the above-described conveying direction is used to describe the lower side of the second liquid and the second liquid, and the downstream side. The one that is used for discharge and has a higher viscosity. According to this configuration, the coating liquid can be made to enter. The wettability of the material becomes good. In the case of i, the wettability refers to the ease of application when the coating sentence is evenly spread over the entire feeding material. Generally, the coating liquid having a lower viscosity is better than the coating liquid having a higher viscosity. Therefore, when two coating layers are formed, the side (first) cloth which is in contact with the feeding material is low in liquidity, which can improve the wettability of the coating liquid to the feeding material. In the coating apparatus, a vacuum chamber is provided on the upstream side of the outlet provided on the upstream side in the above-described conveying direction. According to this configuration, air can be prevented from being mixed into the liquid coated with the feed material through the vacuum chamber. In the coating apparatus, it is preferable that each of the die outlets for discharging the outlet of the first liquid and the outlet for discharging the second liquid is formed with a radius of curvature of 1 〇〇 y m or less. According to this configuration, since the die edge is relatively sharp, the coated surface can be kept smooth to prevent the incorporation of bubbles in 201200247. Especially θ, (4) 1... Feeding material with low gas or gas permeability is more effective when it is laminated. Further, since the sharply formed die edge is located at the portion 16 of the feed material exiting the die coater, the breakage of the adhesive becomes good, thereby suppressing the flow of the adhesive to the side of the die coater. Further, the radius of curvature of the die blade is preferably 30 " m or more. The reason is that although there is no problem in coating, if the radius of curvature is too small, the die edge is easily broken during processing. In the soil cloth apparatus, a temperature adjustment unit that adjusts the temperature of the liquid is provided in each of the first supply unit and the second supply unit. According to this configuration, when the viscosity of each of the liquid and the second liquid is different, the viscosity of the two liquids can be made equal by adjusting one liquid temperature or both liquid temperatures, thereby having a contact with the two liquids. The advantage of mixing is easy. In the coating apparatus, the die coater has adjustment portions for adjusting the slit length at both end portions in the slit longitudinal direction of the respective outlets, and each of the adjustment portions includes a slit length adjusting piece 'connected to the outlet The slit and the liquid volume connected to the slit are slidable in the slit longitudinal direction to have a slit moving portion that moves in the slit and a liquid volume moving portion that moves in a portion of the liquid volume And a fixing piece that moves in a remaining space of the liquid volume in the longitudinal direction of the slit to fix the slit length adjusting piece, wherein the fixing piece has an inclined pressing surface 'through an outer side from the longitudinal direction of the slit The liquid volume storage moving portion of the slit length adjusting piece is pressed into the reservoir 8 201200247 at the inner side. According to this configuration, when the slit length (coating width) is adjusted, the slit can be removed by moving the solid sheet toward the direction of pulling out from the inner side to the outer side in the longitudinal direction of the slit. The liquid volume of the length regulating piece is stored at a position where the moving portion is pressed to the liquid volume, so that the slit length is adjusted, that is, the fixing of the sheet is loosened. Then, the slit length regulating piece is slid in the longitudinal direction of the slit, and after the slit length regulating piece is moved to the designated position, the fixing piece is pressed inward from the outer side in the longitudinal direction of the slit. The slit length is pressed along the inclined side of the fixing piece to press the slit length regulating piece toward the slit side, whereby the liquid piece of the fixing piece can be adjusted to the liquid volume and the moving portion is pressed to the liquid volume and the slit length is made. Adjustment piece (4). Therefore, the slit length can be easily adjusted by fixing the slit length regulating pieces at the designated positions i on both sides of the slit-like output α. Further, since the fixing piece and the slit length regulating piece are moved in the longitudinal direction of the slit, the movable portion of the fixing piece & slit length adjusting piece can be prevented from sliding off from the liquid volume, so that the workability is greatly improved. Further, by forming the inclined pressed surface opposite to the pressing surface of the fixing piece in advance on the slit length regulating piece, the gap between the slit length adjusting piece and the fixing piece can be reduced, thereby further Improve sealing. In the coating apparatus, it is preferable that a total thickness of a layer formed of the first liquid and a layer formed of the second liquid applied to the feed material is 0.7/ζη or more. Namely, by setting the total layer thickness to 0.7/m or more, the adhesion required for bonding the two feed materials can be ensured. On the other hand, by setting the total thickness of the layer to be equal to or lower, 201200247 °, in the case where the unevenness formed by printing on the feed material can be absorbed, the excess layer thickness is reduced and bonded. In the coating apparatus, a help roller is provided at a position facing the die coater of the feed line of the feed material, and the assist roller is a downstream side of an outlet located on the downstream side in the transport direction of the pair of outlets The top end face of the die abuts against the circumferential surface of the above-mentioned aid stick. According to this structure, even if the roundness of the assisting roller is not fine, the tip end surface of the die is effectively prevented from being generated by elastically deforming the auxiliary roller. A large gap is formed between the crucible and the circumferential surface of the aid roller, or the top end surface of the die is firmly pressed against the circumferential surface of the aiding parent, resulting in insufficient film thickness of the coating liquid, so that the coating can be uniformly set. The film thickness of the coating liquid on the above feed material. Advantageous Effects of Invention According to the above configuration of the present invention, since the first liquid and the second liquid 1 are separately supplied from the two inlets to the respective outlets of the die coater, even if the work is temporarily stopped in order to change the coating width, the interior of the soil spreader is also And the first indication of the first liquid and the second liquid, respectively. The two liquids in the ρ and the second supply unit are not in contact, so that there is no solidified sword inside, which simplifies the preparation work. In addition, since the liquid is applied to the material from the two outlets of the die coating, it is possible to prevent the coating liquid from being torn by the feed material and the roller as in the case of 121'. slip. In addition, it also prevents the occurrence of cinnamon folds. </ RTI> EMBODIMENT 10 201200247 Hereinafter, embodiments of the present invention will be specifically described.

The temperature adjustment portion specifically includes: a die coater The outer surface (side surface) of the opening 5 (three in the illustrated example) water supply ports 51a, 51b, 51c; the same number of water outlets 52 & 52b, 52c; three not shown The internal passage of the system; and the warm water loopers 55a, 55b 55c 'the warm water loopers 55a, 55b, 55c supply warm water through the pipes 53a, 53b, the ten water supply ports 51a to 51c, and make the warm water After passing through the internal passage, the water is returned from the respective drain ports 52 & to 52c via the pipe edges 54c. The internal passages of the three systems are passages provided in the interior of the die coater 5, and the water supply is provided on the side of the die-coating 5 Port 51a, etc. and the drain port 52a, etc., so that from the supply of 7k π c, The warm water that has entered the mold coater 5, such as the water supply port 51a, is discharged from the drain port 52a or the like after a plurality of times, for example, twice in the slit length direction B to be described later. The machines 55a to 55c are common and have a heater (not shown) for heating the temperature of the warm water to the height of the water. The temperature adjustment unit of the structure: B v ^ is in the chess coater 5. The liquid temperature is adjusted as follows: 1 νη includes 13 201200247 water supply port 51 a disposed near the inlet 7a, corresponding drain port 52a, and circulating warm water at the water supply port 51 a and the drain port 52a The first system of the warm water looper 55a adjusts the temperature of the first liquid 8 supplied to the inlet 7a.

In addition, the second system can also adjust the temperature of the first liquid 8 instead of adjusting the second liquid. The temperature of 9 "in addition, in this example, its structure is three systems including the first to third systems, but may also include any number of systems. Further, on the upstream side of the feed material conveying direction a of the die coater 5, a vacuum chamber 59a is provided which passes around the periphery of the π 6a, 6b of the die coater 5 and is reduced inside. The pressure suppresses the incorporation of air into the first liquid 8 and the second liquid 9 which are led out from the respective outlets 6a, 6b. 66 in Fig. 2 is a pump for vacuuming. Fig. 4 is an enlarged view of the head 5a in the vicinity of the portion of the coating machine 5. Further, the vacuum chamber is omitted in Fig. 3. The pair of outlets 6a, 6b are provided separately from each other in the mold coater 5a 5a. Further, the outlets 6a and the outlets 6a are arranged adjacent to each other in the conveying direction A of the first feeding material 2, so that the first liquid second liquid 9 is immediately discharged from the respective outlets 6a and 6b. Contact. Further, the mold edge 5a is provided with a die edge r (-coffee) 563 associated with the upstream side 14 201200247 6a of the conveyance direction A, and a die edge 56b associated with the downstream side outlet 6b of the conveyance direction A. It is relatively sharp. ...heart, shape rate" 1ηΛ ..., 5讣 are all set to be "100" or less, and in this embodiment, it is set to 6Mm. Further, l'V6a is the edge on the upstream side of the outlet 6b on the downstream side, and the die edge 56b is the edge of the downstream end of the wedge head 5a. The reason why the radius of curvature of the coating == mold is to smooth the ’ and prevent the bubbles from being mixed into the coating portion of the dispensing agent. XI 2: In the feed material with low permeability or permeability, the radius of the layer is repeated, and the phase is 3G \ heart, 565 curvature... " The reason is that although there is no problem even if the coating is applied, if the radius of curvature is too small, the mold and the problem of easy material shortage occur during processing. Further, in order to suppress the occurrence of defects in the die edges 56a and 56b, it is preferable to use a hard metal material such as sus42〇j-2 as the die. "' Heat treatment of the portions of the broaching ports 56a, 56b to increase the hardness. Further, by setting the length u of the lip (1) p) of the die 5a to 35, the amplitude L2 of the slit connected to the outlet 6a and the width U of the slit connected to the outlet are set to 2", respectively. In addition, it is possible to prevent unevenness in the flow of the liquid and to keep the coated surface smooth. In addition, the upper end portion 5 of the die 5a on the upstream side of the feed material A is "referenced to the circle 4". A feed material 2 does not wrinkle to form a smooth curved surface. Further, in order to make the first feed material 2 easy to slide, it is processed into a mirror surface. Further, in the die coater 5, 15 201200247 is provided with an adjusting portion for adjusting the slit length (coating width) which will be described later. In the coating device of the present embodiment having the above configuration, the first liquid which is respectively led out from the two outlets 6a and 6b of the die coater 5 is supplied to the first feed material 2 conveyed along the first transfer line 1G. 8 and the second liquid 9. After the absence, the second feeding material 3 conveyed in the second conveying line 2 is attached to the first feeding material 2 H [the feeding material 2 passes through the upstream side in the conveying direction A from the feeding material 枓The first liquid 8 supplied to the first feed material 2 is overlapped with the second liquid 9 which is led out from the outlet 6b on the downstream side in the feed material conveying direction A, and is coated with the two liquids 8, 9 The produced laminated product 4 is conveyed along the third transfer line 3〇. As described above, since the first liquid 8 and the second liquid 9 are separately supplied from the respective inlets 7&, several to the respective outlets 6a and 6b of the die coater 5, even if the operation is temporarily stopped for replacement of the size, the mold is coated with 贞5. The first supply portion 4A and the second supply portion 6 that supply the first liquid 8 and the second liquid 9, respectively, are provided. In the case where there is no contact between the two liquids 8, 9 and the solidified state, the above-mentioned size replacement and the like can be simplified. Further, since the liquids 8 and 9 are applied to the first feed material 2 from the two outlets 6a and 6b of the die coater 5, the coating liquid is not fed to the material and the roller as in the conventional example of H8. Tear 'to keep the coated surface smooth. In addition, orange peel wrinkles can be prevented. Further, in the coating device of the present embodiment, the supply amount ' of the first liquid 8 supplied from the outlet & on the upstream side in the feed material conveying direction A is set more than from the feed material conveying direction a a supply amount of the second liquid 9 supplied from the outlet 6b on the downstream side, so that a layer (first layer) of a thicker first liquid 8 having a larger supply amount can be formed on the first feed material 16 201200247 material 2, Then, a layer (second layer) of a thinner second liquid 9 which is supplied in a small amount is formed, whereby air can be suppressed from being mixed into the coated portion of the adhesive. In other words, by forming a thicker layer of the first liquid 8 on the side of the outlet 6a on the upstream side in the conveying direction A of the first feeding material 2, the conveying direction between the die coater 5 and the first feeding material 2 can be blocked. The gap on the upstream side makes it difficult to mix air when forming the layer of the second liquid. In the case of b, the ratio of the discharge amount of the first liquid 8 to the discharge amount of the second liquid 9 is preferably about 5:2 in the structure of the coating liquid used in the above-described first embodiment. Further, the structure of the coating liquid used in the second embodiment described above is preferably about 2:1. Further, the total layer thickness of the layer (first layer) of the first liquid 8 and the layer (first layer) of the second liquid 9 is preferably 〇. 7 " m or more and 5 " m or less. In other words, if the total layer thickness is set to 〇·7..., it is possible to face the dry force required for the two feeds and the dryness of the cloth. On the other hand, by setting the total layer thickness to 5 (four), the excess layer thickness can be reduced and dried in a state in which the unevenness formed by printing on the feed material can be absorbed. In addition, it is more desirable that the total layer thickness is 12" In other words, if the total thickness of the layer is 3 (four) or less, the unevenness generated on the ordinary feeding material that is not subjected to the brushing can be absorbed and dried, and if it is set to 1. 2 m or more , to prevent uneven bonding.

The second liquid q having a lower degree is the reason why the first layer is stabilized by first forming a layer of the first liquid 8 having a higher viscosity of 17 201200247, and then forming a second liquid having a lower viscosity. When the layer of 9 is used, the two layers can be easily and appropriately laminated. However, when there is a problem in the wettability with respect to the coating liquid of the first feed material 2, the wettability can be improved by first applying a coating liquid having a low viscosity. That is, by first applying the first liquid 8 to the first feed material 2 with a smooth spread, the coatability of the second coating liquid 9 can be improved, and the linear velocity of the first transfer line 10 can be increased. Further, according to the above-described mold application method in which the first liquid 8 and the second liquid 9 are directly supplied to the first feed material 2, there is no possibility that the liquid viscosity is 500 Pas or less (cps) or less when applied by roll coating. The problem of the coating liquid has an advantage that it can be used even at a coating liquid of, for example, 500 Pas (cps) or less. Further, in the case where the viscosity of the first liquid 8 is different from the viscosity of the second liquid 9, when the viscosity of the two liquids 8, 9 is to be the same level, the temperature adjusting portion provided in the die coater 5 can be used. At least one of the first liquid 8 and the second liquid 9 is heated and used. Further, when the viscosity of the two liquids 8, 9 is made uniform as described above, it is also advantageous in that mixing with the contact of the first liquid 8 and the second liquid 9 can be facilitated. In the coating liquid of the second embodiment described above, since the fatty acid polyisocyanate as the first liquid 8 has a dryness of 1420 Pas at a temperature of 70 C, the temperature of the polylactic acid polyol of the second liquid 9 is passed. Adjusted to about 85, it can be made close to the viscosity of the first liquid 8. In addition, by operating the vacuum chamber 59 provided on the upstream side in the transport direction A of the outlet 6a, the air in the die coater 5 is evacuated, and it is possible to suppress the application of the air to the first feed material 2 in 201200247. The liquid is 8, 9 in. 5 ( I a) is a front view schematically showing an adjustment portion for adjusting the length of the slit, and a side view thereof. The adjusting portions 70 are respectively provided at both end portions of the longitudinal direction 8 of the slits of the respective exits 6a, 6b of the die coater 5. Further, the two-dot chain line in Fig. 5 (a) indicates a liquid flow. Each of the grading portions 70 includes a slit length regulating piece 71 (a shadow knife that descends to the right) and a fixing piece 72 (a hatched portion that rises to the right). These slits. The flap 71 and the fixing #72 are provided to be slidable inside the liquid path 73 which is formed in advance in the die coat: 5. The groove of the liquid path 73 differs in the depth direction c of the slit, and the liquid path 73 has a slit 73a of a certain width connected to the outlets 6a &b; and the inner side of the liquid path and the slit The liquid volume 73b of the substantially circular cavity connected by 73a is stored. This liquid volume storage 73b is used to make the liquid flow at each position of the slit 73a along the longitudinal direction b of the slit uniform. The slit length regulating piece 71 includes a slit moving portion 71a that moves in the slit 73a along the slit longitudinal direction 8, and a kneading surface that moves in a part of the liquid volume portion 73b (portion close to the slit 73a) The liquid volume in the shape of an arc is stored in the moving portion 71b. A flat pressed surface 71c is formed on the inner deep side of the liquid volume portion 73b of the moving portion 7n], and the liquid volume moving portion 71b forms a taper, so that the pressed surface 71c is formed. The outer side inclined in the longitudinal direction b of the slit is closer to the outlet 6a (6b) than the inner side. The slit moving portion 71a has an amplitude dimension substantially equal to that of the slit 73a. The cross-sectional shape of the liquid volume storage moving portion 71b is substantially the same as a part of the liquid volume storage portion 73b (portion close to the narrow hole 73a), and the semiconductor moving portion 71b is prevented from falling off toward the outlet 6a (6b) side, and the slit moving portion 71a is formed. Wide width. The fixing piece 72 moves in the remaining space other than the internal cavity removing liquid volume moving portion 71b of the liquid volume portion 73b, and forms a cross-sectional shape in which a part of the circle is lacking. Further, a flat pressing surface 72a opposed to the inclined pressed surface 71c of the slit length regulating piece 71 is provided at the end of the fixing piece 72, and the fixing piece 72 is formed in a wedge shape so that the pressing surface 72a It is inclined to be outwardly lowered corresponding to the above-mentioned pressed surface 71c. Therefore, by pressing the fixing piece 72 from the outer side in the slit longitudinal direction B to the inner side, through the above-mentioned pressing surface? 2a presses the pressed surface 71c of the slit length regulating piece 71 toward the slit 73a side, and presses the liquid volume storage portion 71bb of the slit length regulating piece 71 toward the liquid volume storage portion 73b to fix it at the designated position, passing the narrow The inner end portion of the slit length regulating piece 71 limits the coating width. Therefore, in the adjustment portion 7 of the structure, when the slit length (coating towel width) is adjusted, the fixing piece 72 is moved in the pulling direction from the inner side toward the outer side in the slit length direction B, thereby fixing the fixing piece. The inclined pressing surface 72a of the 72 is separated from the pressed surface 71c, whereby the force for pressing the liquid volume storing portion 71b of the slit length regulating piece 71 to the liquid volume 73b is released, so that the slit length is adjusted. The sheet 71 can be moved. Then, the slit length adjusting piece 71 is slid in the slit length direction B, and after the slit length regulating piece 7^ is moved to the designated position, the fixing piece 72 is pressed inward from the outer side in the slit length direction B. By thus pressing the inclined pressing faces 7 & of the fixing piece 7 2 against the pressed surface 71c of the slit length regulating piece 71, the liquid volume is moved. P 71b is squeezed to the liquid reservoir 73b, thereby fixing the slit length adjustment 20 201200247 The sheet 71 is solidified. Thereby, the slit length can be easily adjusted. Further, although the fixing piece 72 and the slit length regulating piece 71 are thus moved in the longitudinal direction of the slit, the liquid volume moving portion 71b which prevents the fixing piece 72 and the slit length regulating piece π from being slidable from the liquid volume portion 73b The ground is detached, and the workability is greatly improved. Further, since the pressed surface 71c of the slit length regulating piece π and the pressing surface 72a of the fixing piece 72 form a reversed slanting of the slanting sheet, the sealing property can be improved. Further, only the pressing surface 72a of the fixing piece 7 2 may be inclined, and even in this case, the slit length regulating piece 71 may be fixed. As the aid roller 3a in the above-described first embodiment, a metal roller mainly composed of a steel official material or the like, or a rubber roller provided with a synthetic rubber material layer on the outer peripheral surface may be used, but a help roller using a metal roller is used. At the time of 13a, since the roundness can be ensured with high precision, it is possible to effectively suppress the occurrence of coating unevenness caused by the vibration of the aiding pro 13a. On the other hand, when the elastic rubber roller is used as the auxiliary view i3a, there is an advantage that the peripheral end portion of the die 5a is abutted against the circumferential surface of the assist roller 13a via the first feed material 2 described above. In the state, the first cloth 8 and the second coating liquid 9 are uniformly applied to the first feed material 2 by the k cloth.

That is, 'when the rubber roller using the elastic rubber is used as the auxiliary roller 13a, and the second tip surface portion 67 of the die 5a is crimped to the circumferential surface of the aid roller..." because even the auxiliary roller 13a is round Inaccurate degree, also ° k over the aid of the Kunyu 3a elastic deformation, and effectively prevent the following situation 23 201200247 situation occurs, that is, the assistance roll i 3a rotates at the top face of the die 5a with the aid light 1 3a A large gap is formed between the circumferential surfaces, or the top surface of the die is firmly pressed against the circumferential surface of the aid 13a, resulting in insufficient film thickness of the coating liquid, so that the first feeding material can be uniformly set. The film thickness of the coating liquid on 2. In the above-described second embodiment in which the elastic rubber roller is used as the auxiliary roller 13a, the cutting edges 58a and 58b of the die 5a other than the upstream side end portion 5〇 located upstream in the conveying direction are When the sharp shapes of the arc-free corners are formed by 65a and 56b, it is possible to prevent an excessive gap from being formed between the tip end surface portion of the die 5a and the circumferential surface of the assist roller 13a. Therefore, there is an advantage that the coating liquid layer which can suppress the film thickness of the coating liquid from being unnecessarily increased to form a film on the first feeding material. Further, the respective edges 58a, 58b, 65a, 56b of the die 5a having the sharp shape which forms the above-mentioned arc-free angle are not caused to abut against the damage caused by the circumferential surface of the assist roller formed of the rubber roller. Further, as shown in the second embodiment, the upstream side portion having a wide width of about 2 〇〇 " m is provided at each of the slits connected to the outlet 6a and the outlet 6b formed in the die 5a. , ,..., and the slot width is 2. " In the case of the narrow downstream side portions 68b and 69b of the left side, the supply of the first liquid 8 and the second liquid 9 supplied from the outlet 6a and the outlet 6b to the first feed material 2 can be sufficiently ensured. The amount 'can suppress the first liquid 8 and the second liquid 9' from the downstream side portions 68b and 69b T + , thereby effectively thinning the film thickness of the coating liquid layer formed on the first feed material. 24 201200247 4 [Brief Description of the Drawings] Fig. 1 is a schematic view showing a coating apparatus according to the first embodiment of the present invention.
