　特許文献１には、断面形状がステップ形状である対象に用いるシーリング用のシーラント成形ノズルが開示されている。このシーラント成形ノズルは、シーラントを成形する成形部を備える。成形部は、ステップ形状の上段の上面に接触する第１接触部と、ステップ形状の下段の上面に接触する第２接触部と、第１接触部と第２接触部との間をつなぐ成形面と、を有する。このような構成によれば、成形面と対象とに囲まれた空間に供給されたシーラントは、成形面によって規定形状に成形される。 Patent Document 1 discloses a sealant molding nozzle for sealing used for an object having a stepped cross-sectional shape. The sealant molding nozzle includes a molding portion for molding the sealant. The molded portion is a molded surface that connects the first contact portion that contacts the upper surface of the upper step of the step shape, the second contact portion that contacts the upper surface of the lower stage of the step shape, and the first contact portion and the second contact portion. And have. According to such a configuration, the sealant supplied to the space surrounded by the molding surface and the object is molded into a specified shape by the molding surface.
　特許文献１に開示された構成では、落雷時に対象のステップ形状である部分からスパークが発生するのを抑えるため、ステップ形状の上段の上面の角部を含めステップ形状である部分を覆うようにシーラントを成形する。このため、成形部は、ステップ形状の上段の上面と接触する第１接触部と、ステップ形状の下段の上面と接触する第２接触部との間をつなぐように形成されている。これにより、成形面によって規定形状に成形されるシーラントは、ステップ形状の上端の上面と下段の上面とを結ぶよう、上方に向けて凸となる断面形状となる。したがって、シーラントはステップ形状の上段の上面よりも上方に盛り上がり、上段の上面と側面との角部もシーラントによって覆われる。 In the configuration disclosed in Patent Document 1, in order to prevent sparks from being generated from the target step-shaped portion during a lightning strike, the sealant covers the step-shaped portion including the corner portion of the upper surface of the upper stage of the step shape.

As a result, the sealant molded into the specified shape by the molding surface has a cross-sectional shape that is convex upward so as to connect the upper surface of the upper end of the step shape and the upper surface of the lower stage. Therefore, the sealant rises above the upper surface of the step-shaped upper stage, and the corners between the upper surface and the side surface of the upper stage are also covered with the sealant.

　ところで、例えば、ステップ形状の上段の上面と下段の上面との間の凹みを埋めながらシーラントを薄く塗布する場合がある。特許文献１に開示された構成では、ステップ形状である部分の全体を覆うようにシーラントを塗布する。このため、特許文献１に開示された構成では、薄くシーラントを塗布することができない。 By the way, for example, the sealant may be applied thinly while filling the dent between the upper surface of the upper stage and the upper surface of the lower stage in the step shape. In the configuration disclosed in Patent Document 1, the sealant is applied so as to cover the entire step-shaped portion. Therefore, the sealant cannot be applied thinly with the configuration disclosed in Patent Document 1.

　さらに、凹部に一旦ストックされているシーラントが、成形面と塗布面との間の隙間に向かって供給されるため、成形面と塗布面との間の隙間へ供給されるシーラントが不足しにくい。
　これにより、シーラント成形装置は、シーラントを薄く塗布することが可能となる。 According to this aspect, the sealant is applied between the molded surface and the coated surface with a thickness corresponding to the gap between the molded surface and the coated surface.
Further, since the sealant once stocked in the recess is supplied toward the gap between the molded surface and the coated surface, the sealant supplied to the gap between the molded surface and the coated surface is unlikely to be insufficient.
This allows the sealant molding apparatus to apply the sealant thinly.

As a result, it is not necessary to separately form the portion for accommodating and holding the molded member and the recess, and the cover can be easily manufactured.
　また、第６の態様のシーラント成形装置は、前記窪み部は、前記連続方向の第一側および第二側のいずれか一方に、前記成形部材が選択的に収容可能である第５の態様のシーラント成形装置である。 Further, in the sealant molding apparatus of the sixth aspect, in the fifth aspect, the recessed portion can selectively accommodate the molding member on either the first side or the second side in the continuous direction. It is a sealant molding device.
　この態様によれば、窪み部の連続方向の第二側に成形部材を収容すれば、成形部材の第一側に凹部が形成される。窪み部の連続方向の第一側に成形部材を収容すれば、成形部材の第二側に凹部が形成される。これにより、塗布面に対するシーラント成形装置の進行方向に応じて、窪み部に対して成形部材を収容する位置を変えることができる。したがって、シーラント成形装置を、塗布面に対する進行方向に応じて別々に用意する必要が無い。したがって、シーラント成形装置の汎用性を高めることができる。 According to this aspect, if the molding member is housed on the second side in the continuous direction of the recess, the recess is formed on the first side of the molding member.

It includes a step of applying a sealant to the coated surface and a step of stopping the supply of the sealant from the sealant supply unit and separating the molded member from the coated surface.
　この態様によれば、シーラントが、成形面と塗布面との間の隙間に応じた厚みで塗布面に塗布される。
　さらに、凹部に一旦ストックされているシーラントが、成形面と塗布面との間の隙間に向かって供給されるため、成形面と塗布面との間の隙間へ供給されるシーラントが不足しにくい。

　塗布面Ｆにシーラント１００を塗布する際には、シーラント成形装置１０を、塗布面Ｆが連続する連続方向Ｄｓ（図１参照）の第一側に移動させる。
　例えば、第一方向Ｄ１が連続方向Ｄｓに相当していてもよい。
　図２、図６において、矢印Ａ１、Ａ２は、塗布面Ｆにシーラント１００を塗布する際のシーラント成形装置１０の進行方向を示している。このとき、成形部材３０は、窪み部２２内で、連続方向Ｄｓに沿った進行方向Ａ１，Ａ２の後方（連続方向Ｄｓの第二側）に配置される。成形部材３０は、窪み部２２内で、交差面３６を、進行方向Ａ１，Ａ２の前方（連続方向Ｄｓの第一側）に向けている。交差面３６は、連続方向Ｄｓに交差する塗布面Ｆの幅方向Ｄｗ一方の側から他方の側に向かって、連続方向Ｄｓに傾斜している。
　凹部２４は、成形部材３０の交差面３６に対して、進行方向Ａ１，Ａ２の前方（連続方向Ｄｓの第一側）に隣接している。
　例えば、第二方向Ｄ２が幅方向Ｄｗに相当していてもよい。 When the sealant 100 is applied to the coated surface F, the sealant molding apparatus 10 is moved to the first side in the continuous direction Ds (see FIG. 1) in which the coated surface F is continuous.
For example, the first direction D1 may correspond to the continuous direction Ds.
In FIGS. 2 and 6, arrows A1 and A2 indicate the traveling direction of the sealant molding apparatus 10 when the sealant 100 is applied to the coated surface F. At this time, the molding member 30 is arranged in the recessed portion 22 behind the traveling directions A1 and A2 along the continuous direction Ds (second side of the continuous direction Ds). In the recessed portion 22, the molding member 30 directs the intersecting surface 36 toward the front of the traveling directions A1 and A2 (the first side in the continuous direction Ds).

The recess 24 is adjacent to the front (first side in the continuous direction Ds) of the traveling directions A1 and A2 with respect to the intersecting surface 36 of the molding member 30.
For example, the second direction D2 may correspond to the width direction Dw.
　次に、上記したようなシーラント成形装置１０を用いた塗布面Ｆへのシーラント塗布方法について説明する。
　図７は、本実施形態に係るシーラント塗布方法の流れを示すフローチャートである。
　図７に示すように、本実施形態におけるシーラント塗布方法は、成形部材の成形面を塗布面に対向させる工程Ｓ１と、シーラントを塗布する工程Ｓ２と、成形部材を塗布面から離間させる工程Ｓ３と、塗布面からはみ出したシーラントを除去する工程Ｓ４と、を有する。 Next, a method of applying the sealant to the coated surface F using the sealant molding apparatus 10 as described above will be described.
FIG. 7 is a flowchart showing the flow of the sealant application method according to the present embodiment.
As shown in FIG. 7, the sealant coating method in the present embodiment includes a step S1 in which the molding surface of the molding member faces the coating surface, a step S2 in which the sealant is applied, and a step S3 in which the molding member is separated from the coating surface. The step S4 is for removing the sealant protruding from the coated surface.
　図８は、本実施形態に係るシーラント成形装置の成形部材の成形面を、塗布面に対向させて、シーラントを塗布している状態を示す断面図である。
　成形部材の成形面を塗布面に対向させる工程Ｓ１では、図８に示すように、成形部材３０の成形面３２を塗布面Ｆに対向させる。これには、カバー２０の本体プレート部２１の表面２１ｆを端面４ｆ側に向ける。摺接部２８を、塗布面Ｆの幅方向Ｄｗ一方の側に位置する翼板２の表面（隣接面）２ｆ上に載せる。この状態で、本体プレート部２１および成形部材３０は、ストリンガー３のベース部４の上面４ｔよりも、上方に突出する。これにより、窪み部２２に収容された成形部材３０の成形面３２が、塗布面Ｆとなる端面４ｆに対向する。成形面３２は、塗布面Ｆに沿う。シーラント供給孔２５は、塗布面Ｆと対向する位置に配置される。また、予め、シーラント１００を吐出するシーラントガン（図示無し）をシーラント供給孔２５に接続しておく。
　なお、成形部材３０は、窪み部２２内で、シーラント成形装置１０を塗布面Ｆの連続方向Ｄｓに沿ったシーラント成形装置１０の進行方向後方側に配置する。これにより、成形部材３０の交差面３６は、連続方向Ｄｓの第一側（進行方向前方）を向いている。 FIG. 8 is a cross-sectional view showing a state in which the sealant is applied with the molding surface of the molding member of the sealant molding apparatus according to the present embodiment facing the coating surface.
In the step S1 in which the molding surface of the molding member faces the coating surface, as shown in FIG. 8, the molding surface 32 of the molding member 30 faces the coating surface F. For this purpose, the surface 21f of the main body plate portion 21 of the cover 20 is directed toward the end surface 4f. The sliding contact portion 28 is placed on the surface (adjacent surface) 2f of the blade plate 2 located on one side of the coating surface F in the width direction Dw. In this state, the main body plate portion 21 and the molding member 30 project upward from the upper surface 4t of the base portion 4 of the stringer 3. As a result, the molding surface 32 of the molding member 30 housed in the recess 22 faces the end surface 4f which is the coating surface F. The molding surface 32 is along the coating surface F. The sealant supply hole 25 is arranged at a position facing the coating surface F. Further, a sealant gun (not shown) for discharging the sealant 100 is connected to the sealant supply hole 25 in advance.
In the molding member 30, the sealant molding device 10 is arranged in the recessed portion 22 on the rear side in the traveling direction of the sealant molding device 10 along the continuous direction Ds of the coating surface F. As a result, the intersecting surface 36 of the molding member 30 faces the first side (forward in the traveling direction) of the continuous direction Ds.
　図９は、本実施形態に係るシーラント成形装置において、シーラントを塗布面に塗布している状態を、塗布面に対向する側から見た図である。
　シーラントを塗布する工程Ｓ２では、図８、図９に示すように、シーラントガンから吐出されるシーラント１００は、シーラント供給孔２５から凹部２４内に供給される。作業者は、シーラント１００を供給しながら、シーラント成形装置１０を塗布面Ｆの連続方向Ｄｓ第一側に進行させる。すると、凹部２４内に供給されたシーラント１００が、塗布面Ｆである端面４ｆと成形部材３０の成形面３２との間に挟み込まれ、塗布面Ｆに付着する。これにより、塗布面Ｆにシーラント１００が塗布される。塗布面Ｆに塗布されるシーラント１００の膜厚は、シーラント１００の粘性、作業者がシーラント成形装置１０を塗布面Ｆに押し付ける力等にもよるが、例えば数ｍｍ以下の薄膜状となる。 FIG. 9 is a view of the sealant molding apparatus according to the present embodiment in which the sealant is applied to the coated surface as viewed from the side facing the coated surface.
In the step S2 of applying the sealant, as shown in FIGS. 8 and 9, the sealant 100 discharged from the sealant gun is supplied into the recess 24 from the sealant supply hole 25. While supplying the sealant 100, the operator advances the sealant molding apparatus 10 toward the continuous direction Ds first side of the coating surface F. Then, the sealant 100 supplied into the recess 24 is sandwiched between the end surface 4f, which is the coating surface F, and the molding surface 32 of the molding member 30, and adheres to the coating surface F. As a result, the sealant 100 is applied to the coated surface F. The film thickness of the sealant 100 applied to the coated surface F depends on the viscosity of the sealant 100, the force with which the operator presses the sealant molding device 10 against the coated surface F, and the like, but is, for example, a thin film of several mm or less.
　また、凹部２４内に供給されたシーラント１００のうち、塗布面Ｆと成形面３２との間に入り込まずに、塗布面Ｆからはみ出した余剰のシーラント１００ｗは、成形部材３０の交差面３６の傾斜により、塗布面Ｆから、塗布面Ｆの幅方向Ｄｗ一方の側のベース部４の上面４ｔ側に押しやられる。 Further, of the sealant 100 supplied into the recess 24, the excess sealant 100w that does not enter between the coating surface F and the molding surface 32 and protrudes from the coating surface F is inclined at the intersection surface 36 of the molding member 30. As a result, the coating surface F is pushed from the coating surface F to the upper surface 4t side of the base portion 4 on one side of the width direction Dw of the coating surface F.
　ところで、図９に示すように、作業者は、シーラント成形装置１０で塗布面Ｆにシーラント１００を塗布する際、２本以上の手指Ｍを、例えば、保持突起２９と、本体プレート部２１において保持突起２９と反対側の端部とに掛ける。これにより、作業者は、シーラント成形装置１０を安定的に保持して作業を行うことができる。 By the way, as shown in FIG. 9, when the sealant 100 is applied to the coating surface F by the sealant molding apparatus 10, the operator holds two or more fingers M on, for example, the holding protrusion 29 and the main body plate portion 21. Hang on the end opposite to the protrusion 29. As a result, the operator can stably hold the sealant molding apparatus 10 and perform the work.
　シーラントを塗布する工程Ｓ２では、塗布面Ｆに対し、連続方向Ｄｓに沿って所定長にわたってシーラント１００を塗布したら、シーラント１００の塗布を完了する。 In the step S2 of applying the sealant, when the sealant 100 is applied to the coated surface F over a predetermined length along the continuous direction Ds, the application of the sealant 100 is completed.
　成形部材を塗布面から離間させる工程Ｓ３では、シーラント１００の塗布が完了した後、シーラント供給孔２５からのシーラント１００の供給を停止する。その後、シーラント成形装置１０を、塗布面Ｆから引き離すことで、成形部材３０を塗布面Ｆから離間させる。 In the step S3 of separating the molded member from the coated surface, the supply of the sealant 100 from the sealant supply hole 25 is stopped after the coating of the sealant 100 is completed. After that, the sealant molding apparatus 10 is separated from the coating surface F to separate the molding member 30 from the coating surface F.
　図１０は、本実施形態に係るシーラント塗布方法において、塗布面からはみ出した余剰のシーラントを除去する状態を示す断面図である。
　塗布面からはみ出したシーラントを除去する工程Ｓ４では、図１０に示すように、塗布面Ｆからはみ出し、交差面３６によって塗布面Ｆの幅方向Ｄｗ一方の側のベース部４の上面４ｔ側に押し出された余剰のシーラント１００ｗを、例えばヘラ２００等で除去する。やられる。 FIG. 10 is a cross-sectional view showing a state in which excess sealant protruding from the coated surface is removed in the sealant coating method according to the present embodiment.
In the step S4 of removing the sealant protruding from the coated surface, as shown in FIG. 10, the sealant protrudes from the coated surface F and is extruded by the intersecting surface 36 to the upper surface 4t side of the base portion 4 on one side of the width direction Dw of the coating surface F. The excess sealant 100w is removed with a spatula 200 or the like. Can be done.
　このように、シーラント成形装置１０を用いることで、塗布面Ｆに、略均一な膜厚でシーラント１００が塗布される。 In this way, by using the sealant molding apparatus 10, the sealant 100 is applied to the coated surface F with a substantially uniform film thickness.
　本実施形態のシーラント成形装置１０は、塗布面Ｆに対向する成形面３２を有する成形部材３０と、成形部材３０を保持するカバー２０と、カバー２０において、成形部材３０に対して塗布面Ｆが連続する連続方向の第一側に隣接して設けられ、成形面３２よりも塗布面Ｆから離間する方向に凹んだ凹部２４と、凹部内にシーラントを供給可能なシーラント供給孔２５と、を備える。このような構成によれば、シーラント供給孔２５で凹部２４内にシーラント１００を供給しながら、塗布面Ｆが連続する連続方向Ｄｓの第一側にカバー２０を移動させると、カバー２０に保持された成形部材３０により、シーラント１００が成形される。成形部材３０の成形面３２は、塗布面Ｆに対向しているので、シーラント１００は、成形面３２と塗布面Ｆとの間に、成形面３２と塗布面Ｆとの間の隙間に応じた厚みで塗布される。これにより、シーラント１００を薄く塗布することが可能となる。 In the sealant molding apparatus 10 of the present embodiment, the molding member 30 having the molding surface 32 facing the coating surface F, the cover 20 holding the molding member 30, and the cover 20 have the coating surface F with respect to the molding member 30. It is provided with a recess 24 which is provided adjacent to the first side in a continuous continuous direction and is recessed in a direction away from the coating surface F from the molding surface 32, and a sealant supply hole 25 capable of supplying a sealant in the recess. .. According to such a configuration, when the cover 20 is moved to the first side in the continuous direction Ds where the coating surface F is continuous while supplying the sealant 100 into the recess 24 through the sealant supply hole 25, the cover 20 is held by the cover 20. The sealant 100 is molded by the molded member 30. Since the molding surface 32 of the molding member 30 faces the coating surface F, the sealant 100 corresponds to the gap between the molding surface 32 and the coating surface F and between the molding surface 32 and the coating surface F. It is applied with a thickness. This makes it possible to apply the sealant 100 thinly.
　本実施形態のシーラント成形装置１０は、成形部材３０に対して塗布面Ｆが連続する連続方向の第一側に隣接して凹部２４が設けられている。
　特許文献１に開示されたシーラント成形装置のように、シーラント供給孔から、成形面と塗布面との間へ直接シーラントを供給すると、成形面と塗布面との間へのシーラントの供給が不足する場合がある。
　例えば、シーラントを薄く塗布する場合、シーラントを塗布できていない部分が残ることもある。
　これに対し、本実施形態のシーラント成形装置１０によれば、塗布面Ｆが連続する連続方向Ｄｓの第一側にカバー２０を移動させる場合において、凹部２４に一旦ストックされているシーラントが、成形面３２と塗布面Ｆとの間の隙間に向かって供給される。
　このため、成形面３２と塗布面Ｆとの間の隙間へ供給されるシーラントが不足しにくい。例えば、シーラントを薄く塗布する場合でも、成形面３２と塗布面Ｆとの間の隙間へ供給されるシーラントが不足しにくいため、シーラントを塗布できていない部分が残りにくい。
　これにより、シーラント１００を薄く塗布することが可能となる。 The sealant molding apparatus 10 of the present embodiment is provided with a recess 24 adjacent to the first side in the continuous direction in which the coating surface F is continuous with respect to the molding member 30.
When the sealant is directly supplied between the molded surface and the coated surface from the sealant supply hole as in the sealant molding apparatus disclosed in Patent Document 1, the supply of the sealant between the molded surface and the coated surface is insufficient. In some cases.
For example, when the sealant is applied thinly, a portion where the sealant cannot be applied may remain.
On the other hand, according to the sealant molding apparatus 10 of the present embodiment, when the cover 20 is moved to the first side in the continuous direction Ds where the coating surface F is continuous, the sealant once stocked in the recess 24 is molded. It is supplied toward the gap between the surface 32 and the coating surface F.
Therefore, the sealant supplied to the gap between the molding surface 32 and the coating surface F is unlikely to be insufficient. For example, even when the sealant is applied thinly, the sealant supplied to the gap between the molded surface 32 and the coated surface F is unlikely to be insufficient, so that the portion where the sealant has not been applied is unlikely to remain.
This makes it possible to apply the sealant 100 thinly.
　また、成形面３２が、塗布面Ｆに沿った形状を有する。このため、シーラント１００は、塗布面Ｆと、塗布面Ｆに沿った形状の成形面３２とに挟まれて、塗布面Ｆが連続する連続方向Ｄｓに一定の厚さで塗布される。 Further, the molding surface 32 has a shape along the coating surface F. Therefore, the sealant 100 is sandwiched between the coating surface F and the molding surface 32 having a shape along the coating surface F, and is coated with a constant thickness in the continuous direction Ds where the coating surface F is continuous.
　また、成形部材３０は、カバー２０に対して着脱可能とされている。このため、成形部材３０を適宜交換することができる。 Further, the molding member 30 is removable from the cover 20. Therefore, the molding member 30 can be replaced as appropriate.
　また、カバー２０は、連続方向Ｄｓに延びるとともに、塗布面Ｆから離間する方向に窪む窪み部２２を有する。窪み部２２は、連続方向Ｄｓの第二側に成形部材３０が収容され、連続方向Ｄｓにおいて成形部材３０の第一側が凹部２４とされている。このため、窪み部２２の連続方向Ｄｓ第二側に成形部材３０を収容すれば、成形部材３０の第一側に凹部２４が形成される。これにより、成形部材３０を収容する部分と、凹部２４とを別々に形成する必要が無く、カバー２０を容易に製作することができる。 Further, the cover 20 has a recessed portion 22 that extends in the continuous direction Ds and is recessed in the direction away from the coating surface F. In the recessed portion 22, the molding member 30 is housed on the second side of the continuous direction Ds, and the first side of the molding member 30 is the recess 24 in the continuous direction Ds. Therefore, if the molding member 30 is housed on the second side of the recessed portion 22 in the continuous direction Ds, the recess 24 is formed on the first side of the molding member 30. As a result, it is not necessary to separately form the portion accommodating the molding member 30 and the recess 24, and the cover 20 can be easily manufactured.
　また、窪み部２２は、連続方向Ｄｓの第一側および第二側のいずれか一方に成形部材３０が選択的に収容可能である。このため、塗布面Ｆに対するシーラント成形装置１０の進行方向Ａ１、Ａ２に応じて、窪み部２２に対して成形部材３０を収容する位置を変えることができる。したがって、シーラント成形装置１０を、塗布面Ｆに対する進行方向に応じて別々に用意する必要が無く、シーラント成形装置１０の汎用性を高めることができる。 Further, in the recessed portion 22, the molding member 30 can be selectively accommodated on either the first side or the second side of the continuous direction Ds. Therefore, the position of accommodating the molding member 30 with respect to the recessed portion 22 can be changed according to the traveling directions A1 and A2 of the sealant molding apparatus 10 with respect to the coated surface F. Therefore, it is not necessary to separately prepare the sealant molding apparatus 10 according to the traveling direction with respect to the coated surface F, and the versatility of the sealant molding apparatus 10 can be enhanced.
　成形部材３０は、成形面３２において凹部２４に隣接する側の端部に、成形面３２および連続方向Ｄｓに交差する交差面３６を有する。このため、成形面３２と塗布面Ｆとの隙間に入り込まずにはみ出したシーラント１００を、交差面３６により、シーラント成形装置１０の進行方向Ａ１、Ａ２に押して移動させることができる。 The molding member 30 has an intersection surface 36 that intersects the molding surface 32 and the continuous direction Ds at the end of the molding surface 32 on the side adjacent to the recess 24. Therefore, the sealant 100 that protrudes without entering the gap between the molding surface 32 and the coating surface F can be pushed and moved by the intersecting surface 36 in the traveling directions A1 and A2 of the sealant molding apparatus 10.
　交差面３６は、連続方向Ｄｓに交差する塗布面Ｆの幅方向Ｄｗ一方の側から他方の側に向かって、連続方向Ｄｓに傾斜している。このため、成形面３２と塗布面Ｆとの隙間に入り込まずにはみ出した余剰のシーラント１００ｗを、塗布面Ｆの幅方向Ｄｗ一方の側のみに押し出すことができる。したがって、シーラント１００の塗布面Ｆへの塗布後、塗布面Ｆの幅方向Ｄｗ一方の側のみで、はみ出した余剰のシーラント１００ｗの除去を行えばよく、作業性が改善される。 The intersecting surface 36 is inclined in the continuous direction Ds from one side of the width direction Dw of the coating surface F intersecting the continuous direction Ds to the other side. Therefore, the excess sealant 100w that does not enter the gap between the molding surface 32 and the coating surface F can be extruded only on one side of the coating surface F in the width direction Dw. Therefore, after the sealant 100 is applied to the coated surface F, the excess sealant 100w that protrudes may be removed only on one side of the coated surface F in the width direction Dw, and the workability is improved.
　カバー２０が、塗布面Ｆの幅方向Ｄｗいずれか一方の側に、塗布面Ｆに隣接する翼板２の表面２ｆに摺接する摺接部２８を有する。このため、摺接部２８を塗布面Ｆに翼板２の表面２ｆに摺接させながら、シーラント成形装置１０を塗布面Ｆの連続方向Ｄｓに移動させることができる。これにより、シーラント１００を成形面３２に安定して塗布することができる。 The cover 20 has a sliding contact portion 28 that is in sliding contact with the surface 2f of the blade plate 2 adjacent to the coating surface F on either side of the coating surface F in the width direction Dw. Therefore, the sealant molding apparatus 10 can be moved in the continuous direction Ds of the coating surface F while the sliding contact portion 28 is in sliding contact with the coating surface F and the surface 2f of the blade plate 2. As a result, the sealant 100 can be stably applied to the molding surface 32.
　また、本実施形態のシーラント塗布方法は、シーラント成形装置１０を用いたシーラント塗布方法であって、成形部材３０の成形面３２を塗布面Ｆに対向させるとともに、凹部２４を成形部材３０に対して連続方向Ｄｓ第一側に配置する工程Ｓ１と、シーラント供給孔２５からシーラント１００を供給しながら、シーラント成形装置１０を連続方向Ｄｓ第一側に進行させ、塗布面Ｆにシーラント１００を塗布する工程Ｓ２と、シーラント供給孔２５からのシーラント１００の供給を停止し、成形部材３０を塗布面Ｆから離間させる工程Ｓ３と、を有する。このような塗布方法によれば、シーラント１００が、成形面３２と塗布面Ｆとの間の隙間に応じた厚みで塗布面Ｆに塗布される。これにより、シーラント１００を薄く塗布することが可能となる。 Further, the sealant coating method of the present embodiment is a sealant coating method using the sealant molding apparatus 10, in which the molding surface 32 of the molding member 30 faces the coating surface F and the recess 24 is formed on the molding member 30. A step S1 of arranging the sealant 100 on the first side of the continuous direction Ds and a step of advancing the sealant forming apparatus 10 to the first side of the continuous direction Ds while supplying the sealant 100 from the sealant supply hole 25 to apply the sealant 100 to the coating surface F. It has S2 and a step S3 of stopping the supply of the sealant 100 from the sealant supply hole 25 and separating the molding member 30 from the coating surface F. According to such a coating method, the sealant 100 is applied to the coating surface F with a thickness corresponding to the gap between the molding surface 32 and the coating surface F. This makes it possible to apply the sealant 100 thinly.
　上記実施形態において、塗布面Ｆ（端面４ｆ）が、ベース部４の上面４ｔ、および翼板２の表面２ｆに対して直交しておらず、傾斜しているようにしたが、その傾斜角度は何ら限定するものではない。また、塗布面Ｆ（端面４ｆ）が、ベース部４の上面４ｔ、および翼板２の表面２ｆに対して直交していてもよい。 In the above embodiment, the coating surface F (end surface 4f) is not orthogonal to the upper surface 4t of the base portion 4 and the surface 2f of the blade plate 2 and is inclined, but the inclination angle is There is no limitation. Further, the coating surface F (end surface 4f) may be orthogonal to the upper surface 4t of the base portion 4 and the surface 2f of the blade plate 2.
