また、前記の樹脂被覆方法において、前記ポイントの下面がその外縁からその貫通孔にかけて前記貫通孔に近づくにつれて隆起する部分を有することが好ましい。 Moreover, in the said resin coating method, it is preferable that the lower surface of the said point has a part which protrudes as it approaches the said through-hole from the outer edge to the through-hole.

また、本発明は、貫通孔を有するポイントおよび貫通孔を有するダイがそれぞれの貫通孔が縦に並ぶように配置され、前記ポイントと前記ダイの隙間から前記ダイの貫通孔に樹脂が供給可能であり、前記樹脂が供給された前記ダイの前記貫通孔を線条体が通過することにより前記線条体に前記樹脂が塗布される樹脂塗布装置であって、前記ダイの上面がその外縁からその貫通孔にかけて前記貫通孔に近づくにつれて隆起する部分を有し、前記ポイントの下面と前記ダイの上面との距離が前記線条体と直交する方向において変動するように前記ポイントと前記ダイとが組み合わされた樹脂塗布装置に関する。 Further, according to the present invention, a point having a through hole and a die having a through hole are arranged so that the respective through holes are arranged vertically, and resin can be supplied to the through hole of the die from the gap between the point and the die. There is a resin coating apparatus in which the resin is applied to the linear body when the linear body passes through the through-hole of the die supplied with the resin, and the upper surface of the die extends from the outer edge thereof. The point and the die are combined so that the distance between the lower surface of the point and the upper surface of the die fluctuates in a direction perpendicular to the linear body. It is related with the made resin coating apparatus.

前記の樹脂塗布装置において、前記ポイントの下面がその貫通孔の軸に垂直な平面であることが好ましい。 In the resin coating apparatus, it is preferable that the lower surface of the point is a plane perpendicular to the axis of the through hole .

また、前記の樹脂塗布装置において、前記ポイントの下面がその外縁からその貫通孔にかけて前記貫通孔に近づくにつれて隆起する部分を有することが好ましい。 Moreover, the said resin coating apparatus WHEREIN: It is preferable to have a part which the lower surface of the said point protrudes as it approaches the said through-hole from the outer edge to the through-hole.

本発明により、塗布性よく線条体に樹脂を塗布して、前記樹脂を硬化させて樹脂を被覆し、外径が均一、表面がなめらか、樹脂の偏肉がないまたは樹脂中に気泡がないのいずれかを満たす樹脂被覆線条体を製造することができる。 According to the present invention, the resin is applied to the striatum with good coatability, and the resin is cured to cover the resin, the outer diameter is uniform, the surface is smooth, the resin is not uneven, or there are no bubbles in the resin. A resin-coated linear body satisfying any of the above can be produced.

線条体に樹脂を塗布する方法には、図１に示すように、塗布装置１のポイント２とダイ３との隙間に樹脂６を供給し、線条体５をその樹脂６中に通過させる方法がある。この方法では、線条体５が樹脂６を牽引して塗布装置１を出た線条体５に樹脂６が塗布される。線条体５に塗布された樹脂６０を硬化させるには、塗布装置１よりも線条体５の進行方向下流に硬化装置４を配置して、線条体５を硬化装置４に通過させて線条体５に塗布された樹脂６０を硬化させ、これにより被覆線条体７を製造することができる。例えば、樹脂６が紫外線硬化型樹脂であれば、硬化装置４内に紫外線光源を配置して紫外線光源から樹脂６０に紫外線を照射して硬化させることができる。樹脂６が熱硬化型樹脂であれば、硬化装置４内に熱源を配置して熱源から熱を発生させて硬化装置４内を樹脂６０の硬化に必要な温度として樹脂６０を硬化させることができる。 As shown in FIG. 1, the resin 6 is supplied to the gap between the point 2 and the die 3 of the coating apparatus 1, and the linear body 5 is allowed to pass through the resin 6. There is a way. In this method, the linear body 5 pulls the resin 6 and the resin 6 is applied to the linear body 5 exiting the coating apparatus 1. In order to cure the resin 60 applied to the filament 5, the curing device 4 is disposed downstream of the coating device 1 in the traveling direction of the filament 5, and the filament 5 is passed through the curing device 4. The resin 60 applied to the striate body 5 is cured, whereby the coated striate body 7 can be manufactured. For example, if the resin 6 is an ultraviolet curable resin, an ultraviolet light source can be disposed in the curing device 4 and cured by irradiating the resin 60 with ultraviolet rays from the ultraviolet light source. If the resin 6 is a thermosetting resin, a heat source can be arranged in the curing device 4 to generate heat from the heat source, and the resin 60 can be cured at a temperature necessary for curing the resin 60 in the curing device 4. .

本発明では、ポイント２の下面２１とダイ３の上面３１との距離が前記線条体５と直交する方向において変動する形態（第一形態）または前記ポイント２の下面２１および前記ダイ３の上面３１からの距離が等しい仮想面が前記線条体５に垂直な面でない形態（第二形態）とすることにより、外径が均一、表面がなめらか、樹脂の偏肉がないまたは樹脂中に気泡がないのいずれかを満たす樹脂被覆線条体を製造することができる。つまり、塗布性よく線条体に樹脂を塗布して、前記樹脂を硬化させて樹脂被覆線条体を製造することができる。線条体の例には、鋼線、光学繊維などを挙げることができる。 In the present invention, the form in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies in the direction orthogonal to the linear body 5 (first form) or the lower surface 21 of the point 2 and the upper surface of the die 3 By forming the virtual plane having the same distance from 31 as a plane that is not a plane perpendicular to the linear body 5 (second configuration), the outer diameter is uniform, the surface is smooth, there is no uneven thickness of the resin, or there are bubbles in the resin. It is possible to produce a resin-coated filament that satisfies any of the above. That is, a resin-coated filament can be produced by applying a resin to the filament with good coatability and curing the resin. Examples of the striated body include steel wires and optical fibers.

本発明の第一形態では、線条体に樹脂を塗布する塗布装置において、ポイントの下面とダイの上面との距離が、前記線条体または前記ダイの貫通孔の軸に直交する方向において変動する。図２ないし図１６にこの例を示す。 In the first aspect of the present invention, in the coating apparatus for applying a resin to the linear body, the distance between the lower surface of the point and the upper surface of the die varies in a direction perpendicular to the axis of the linear body or the through hole of the die. To do. An example of this is shown in FIGS.

図２に示す塗布装置１では、ポイント２の下面２１をポイント２の貫通孔２２に近づくにつれて隆起（図２では下に向かって突出）する形状としている。なお、ポイントの下面またはダイの上面が隆起するとは、それらの厚さが増大するように変化することをいい、沈降するとはそれらの厚さが減少するように変化することをいう。ポイント２の下面２１は外縁から中程にかけては平面である。一方、ダイ３の上面３１はダイ３の貫通孔３２の軸に垂直な平面としている。このポイント２とダイ３とを組み合わせて、図２に示すように、それぞれの貫通孔２２、３２が縦に並ぶように配置すると、ポイント２の下面２１とダイ３の上面３１との距離はポイント２またはダイ３の外縁からそれらの中程にかけては一定であるが、ポイント２の貫通孔２２またはダイ３の貫通孔３２に近づくにつれてポイント２の下面２１とダイ３の上面３１との距離は短くなっている。これは、ポイント２の下面２１とダイ３の上面３１との距離が線条体５に直交する方向（図２では横方向、以下径方向ということがある）に変動する一例である。本発明では、図２に示すように、ポイント２の下面２１とダイ３の上面３１との距離が、径方向で見て一部の区間で変動していればよく、距離が一定である区間があってもよい。 In the coating apparatus 1 shown in FIG. 2, the lower surface 21 of the point 2 has a shape that protrudes (projects downward in FIG. 2) as it approaches the through hole 22 of the point 2. In addition, when the lower surface of the point or the upper surface of the die is raised, it means that the thickness thereof increases, and when sinking, it means that the thickness changes so as to decrease. The lower surface 21 of the point 2 is a plane from the outer edge to the middle. On the other hand, the upper surface 31 of the die 3 is a plane perpendicular to the axis of the through hole 32 of the die 3. When the point 2 and the die 3 are combined and the through holes 22 and 32 are arranged vertically as shown in FIG. 2, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is a point. 2 or from the outer edge of the die 3 to the middle thereof, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 becomes shorter as approaching the through hole 22 of the point 2 or the through hole 32 of the die 3. It has become. This is an example in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies in a direction perpendicular to the linear body 5 (in FIG. 2, the lateral direction, sometimes referred to as the radial direction hereinafter). In the present invention, as shown in FIG. 2, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 only needs to vary in some sections as viewed in the radial direction, and the distance is constant. There may be.

図３に示す塗布装置１では、ポイント２の下面２１を貫通孔２２近くおよび外縁部分では平面とし、中程で隆起（図３では下に突出）する形状としている。一方、ダイ３の上面３１は図２と同様に平面である。図２と図３とを比較すると、ポイント２の下面２１とダイ３の上面３１との距離が変動する箇所が異なるが、ポイント２の下２１面とダイ３の上面３１との距離が線条体５に直交する方向に変動することに変わりはない。 In the coating apparatus 1 shown in FIG. 3, the lower surface 21 of the point 2 is a flat surface near the through hole 22 and the outer edge portion, and has a shape that protrudes in the middle (projects downward in FIG. 3). On the other hand, the upper surface 31 of the die 3 is a plane as in FIG. 2 and FIG. 3, the location where the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies is different, but the distance between the lower 21 surface of the point 2 and the upper surface 31 of the die 3 is linear. There is no change in changing in the direction perpendicular to the body 5.

図４に示す塗布装置１では、ポイント２の下面２１は貫通孔２２の軸に垂直な平面としている。一方、ダイ３の上面３１は貫通孔３２に近づくにつれて隆起（図４では上に隆起）する形状としている。ダイ３の上面３１は外縁から中程にかけては平面である。これは、図２に示す塗布装置のポイント下面の形状とダイ上面の形状とを入れ替えた構造となっている。したがって、図２に示す塗布装置と同様に、ポイント２の下面２１とダイ３の上面３１との距離はポイントまたはダイの外縁からそれらの中程にかけては一定であるが、線条体５に近づくにつれて短くなっている。これもポイント２の下２１面とダイ３の上面３１との距離が線条体５に直交する方向に変動する例である。 In the coating apparatus 1 shown in FIG. 4, the lower surface 21 of the point 2 is a plane perpendicular to the axis of the through hole 22. On the other hand, the upper surface 31 of the die 3 has a shape that rises as it approaches the through-hole 32 (upward in FIG. 4). The upper surface 31 of the die 3 is a flat surface from the outer edge to the middle. This is a structure in which the shape of the lower surface of the point and the shape of the upper surface of the die of the coating apparatus shown in FIG. 2 are interchanged. Therefore, like the coating apparatus shown in FIG. 2, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is constant from the point or the outer edge of the die to the middle thereof, but approaches the filament 5. As it gets shorter. This is also an example in which the distance between the lower 21 surface of the point 2 and the upper surface 31 of the die 3 fluctuates in a direction perpendicular to the filament 5.

図５に示す塗布装置１では、ポイント２の下面２１を貫通孔２２の軸に垂直な平面としている。一方、ダイ３の上面３１は、貫通孔３２の近くおよび外縁部分では平面とし、中程で隆起（図５では上に突出）する形状としている。これは、図３に示す塗布装置のポイントの下面の形状とダイの上面の形状とを入れ替えた構造となっている。これもポイントの下面とダイの上面との距離が線条体５に直交する方向に変動する例である。 In the coating apparatus 1 shown in FIG. 5, the lower surface 21 of the point 2 is a plane perpendicular to the axis of the through hole 22. On the other hand, the upper surface 31 of the die 3 is flat near the through-hole 32 and at the outer edge portion, and has a shape that protrudes in the middle (projects upward in FIG. 5). This is a structure in which the shape of the lower surface of the point of the coating apparatus shown in FIG. 3 and the shape of the upper surface of the die are interchanged. This is also an example in which the distance between the lower surface of the point and the upper surface of the die varies in a direction perpendicular to the filament 5.

図６に示す塗布装置１では、線条体５の軸を含む断面（図６に示す断面）においてポイント２の下面２１、ダイ３の上面３１をそれぞれを直線となる形状としている。ただし、両直線は平行ではない。ポイント２の下面２１はその外縁からその貫通孔にかけて隆起（図６では下に隆起）する形状であり、ダイ３の上面３１はその外縁からその貫通孔にかけて沈降（図６では下に沈降）にする形状である。このポイント２とダイ３を組み合わせた塗布装置１では、外縁から貫通孔にかけてポイントの下面とダイの上面との距離が一定の比率で短くなる。これも線条体５に直交する方向においてポイント２の下面２１とダイ３の上面３１との距離が変動する例である。 In the coating apparatus 1 shown in FIG. 6, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are each formed in a straight line shape in the cross section including the axis of the filament 5 (the cross section shown in FIG. 6). However, both straight lines are not parallel. The lower surface 21 of the point 2 has a shape that protrudes from its outer edge to its through hole (in FIG. 6, protrudes downward), and the upper surface 31 of the die 3 sinks (sinks downward in FIG. 6) from its outer edge to its through hole. Shape. In the coating apparatus 1 in which the point 2 and the die 3 are combined, the distance between the lower surface of the point and the upper surface of the die is shortened at a constant ratio from the outer edge to the through hole. This is also an example in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies in the direction orthogonal to the filament 5.

図７に示す塗布装置１では、ポイント２の下面２１、ダイ３の上面３１とも外縁から貫通孔にかけて隆起する形状としている。このポイントとこのダイとを組み合わせた塗布装置１では、外縁から貫通孔にかけてポイントの下面とダイの上面との距離が短くなる。図６に示す塗布装置と図７に示す塗布装置とで、それぞれのポイントの下面の傾きが等しいとすれば、図７に示す塗布装置は図６に示す塗布装置よりも樹脂の絞り効率が大きく、樹脂の塗布性に優れる。 In the coating apparatus 1 shown in FIG. 7, both the lower surface 21 of the point 2 and the upper surface 31 of the die 3 have a shape that protrudes from the outer edge to the through hole. In the coating apparatus 1 combining this point and this die, the distance between the lower surface of the point and the upper surface of the die becomes shorter from the outer edge to the through hole. If the coating apparatus shown in FIG. 6 and the coating apparatus shown in FIG. 7 have the same inclination of the lower surface of each point, the coating apparatus shown in FIG. 7 has a higher resin squeezing efficiency than the coating apparatus shown in FIG. Excellent resin applicability.

図８に示す塗布装置１では、ポイント２の下面２１はその外縁からその貫通孔にかけて隆起（図８では下に隆起）する形状であり、ダイ３の上面３１はその外縁からその貫通孔にかけて沈降（図８では下に沈降）する形状であるが、線条体５の軸を含む断面（図８に示す断面）においてポイント２の下面２１、ダイ３の上面３１ともその傾きが途中から変わる形状としている。これは、図６に示す塗布装置のポイント２の下面２１およびダイ３の上面３１それぞれをより複雑な形状した例である。この塗布装置も貫通孔の軸に直交する方向においてポイントの下面とダイの上面との距離が変動する例である。 In the coating apparatus 1 shown in FIG. 8, the lower surface 21 of the point 2 has a shape that rises from its outer edge to its through hole (upwardly in FIG. 8), and the upper surface 31 of the die 3 sinks from its outer edge to its through hole. 8 is a shape that settles down in FIG. 8, but in the cross section including the axis of the filament 5 (the cross section shown in FIG. 8), the lower surface 21 of the point 2 and the upper surface 31 of the die 3 change their inclinations from the middle. It is said. This is an example in which the lower surface 21 of the point 2 and the upper surface 31 of the die 3 of the coating apparatus shown in FIG. This coating apparatus is also an example in which the distance between the lower surface of the point and the upper surface of the die varies in a direction orthogonal to the axis of the through hole.

図９に示す塗布装置１は、線条体５の軸を含む断面（図９に示す断面）においてポイント２の下面２１、ダイ３の上面３１をそれぞれを直線となる形状としている。ただし、両直線は平行ではない。ポイント２の下面２１はその外縁からその貫通孔にかけて沈降（図９では上に沈降）する形状であり、ダイ３の上面３１はその外縁からその貫通孔にかけて隆起（図９では上に隆起）にする形状である。これは、図６に示す塗布装置のポイント２の下面２１の形状とダイ３の上面３１の形状とを入れ替えた構造である。したがって、図６に示す塗布装置と同様に、外縁から貫通孔にかけてポイント２の下面２１とダイ３の上面３１との距離が一定の比率で短くなる。この塗布装置も線条体５に直交する方向においてポイント２の下面２１とダイ３の上面３１との距離が変動する例である。 In the coating apparatus 1 shown in FIG. 9, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are formed in a straight line in the cross section including the axis of the filament 5 (the cross section shown in FIG. 9). However, both straight lines are not parallel. The lower surface 21 of the point 2 has a shape that sinks from the outer edge to the through-hole (sinks upward in FIG. 9), and the upper surface 31 of the die 3 is raised (upward in FIG. 9) from the outer edge to the through-hole. Shape. This is a structure in which the shape of the lower surface 21 of the point 2 of the coating apparatus shown in FIG. 6 and the shape of the upper surface 31 of the die 3 are interchanged. Therefore, similarly to the coating apparatus shown in FIG. 6, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is shortened at a constant ratio from the outer edge to the through hole. This coating apparatus is also an example in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies in the direction orthogonal to the filament 5.

図１０に示す塗布装置１は、ポイント２の下面２１はその外縁からその貫通孔にかけて沈降（図１０では上に沈降）する形状であり、ダイ３の上面３１はその外縁からその貫通孔にかけて隆起（図１０では上に隆起）する形状であるが、線条体５の軸を含む断面（図１０に示す断面）においてポイント２の下面２１、ダイ３の上面３１ともその傾きが途中から変わる形状としている。そして、ポイント２の下面２１とダイ３の上面３１とは平行ではない。これは、図８に示す塗布装置のポイントの下面の形状とダイの上面の形状とを入れ替えた構造である。したがって、図８に示す塗布装置と同様に、この塗布装置１では、外縁から貫通孔にかけてポイントの下面とダイの上面との距離が一定の比率で短くなる。これも線条体５に直交する方向においてポイント２の下面２１とダイ３の上面３１との距離が変動する例である。 In the coating apparatus 1 shown in FIG. 10, the lower surface 21 of the point 2 has a shape that sinks from the outer edge to the through hole (sinks upward in FIG. 10), and the upper surface 31 of the die 3 is raised from the outer edge to the through hole. 10 is a shape that protrudes upward in FIG. 10, but in the cross section including the axis of the filament 5 (the cross section shown in FIG. 10), the inclination of the lower surface 21 of the point 2 and the upper surface 31 of the die 3 changes from the middle. It is said. The lower surface 21 of the point 2 and the upper surface 31 of the die 3 are not parallel. This is a structure in which the shape of the lower surface of the point of the coating apparatus shown in FIG. 8 and the shape of the upper surface of the die are interchanged. Therefore, similarly to the coating apparatus shown in FIG. 8, in this coating apparatus 1, the distance between the lower surface of the point and the upper surface of the die is shortened at a constant ratio from the outer edge to the through hole. This is also an example in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies in the direction orthogonal to the filament 5.

図１１に示す塗布装置では、ポイント２の下面２１およびダイ３の上面３１を貫通孔２２、３２に近づくにつれて隆起する形状としている。このポイント２とこのダイ３とを組み合わせた塗布装置では貫通孔２２、３２に近づくにつれてポイント２の下面２１とダイ３の上面３１との距離が短くなっている。これも線条体５に直交する方向においてポイント２の下面２１とダイ３の上面３１との距離が変動する例である。 In the coating apparatus shown in FIG. 11, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are shaped to rise as they approach the through holes 22 and 32. In the coating apparatus in which the point 2 and the die 3 are combined, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 becomes shorter as it approaches the through holes 22 and 32. This is also an example in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies in the direction orthogonal to the filament 5.

図１２に示す塗布装置１では、ポイント２の下面２１およびダイ３の上面３１を貫通孔２２、３２に近づくにつれて隆起する形状としている点は図１１と同様である。ただし、ダイ３の上面３１の方がポイント２の下面２１よりも隆起する高さが高い。この塗布装置１でも貫通孔２２、３２に近づくにつれてポイント２の下面２１とダイ３の上面３１との距離が短くなっている。貫通孔２２、３２の近くでは、ポイント２の下面２１は貫通孔２２に向かって下向きとなり、ダイ３の上面３１は貫通孔３２に向かって上向きとなるが、ダイ３の上面３１の隆起が急激であるために、ポイント２の下面２１およびダイ３の上面３１からの距離が等しい仮想面８は線条体５に近づくにつれて上向きとなる。つまり、仮想面８が線条体に垂直な面とはならない。 12 is the same as FIG. 11 in that the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are shaped so as to rise as they approach the through holes 22 and 32. However, the height at which the upper surface 31 of the die 3 protrudes is higher than the lower surface 21 of the point 2. Also in this coating apparatus 1, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 becomes shorter as it approaches the through holes 22 and 32. Near the through holes 22, 32, the lower surface 21 of the point 2 faces downward toward the through hole 22, and the upper surface 31 of the die 3 faces upward toward the through hole 32, but the bulge of the upper surface 31 of the die 3 suddenly increases. Therefore, the virtual surface 8 having the same distance from the lower surface 21 of the point 2 and the upper surface 31 of the die 3 becomes upward as it approaches the filament 5. That is, the virtual surface 8 is not a surface perpendicular to the striatum.

図１３に示す塗布装置１では、ポイント２の下面２１およびダイ３の上面３１を貫通孔２２、３２に近づくにつれて隆起する形状としている点は図１１、１２と同様である。ただし、図１２に示す塗布装置とは逆に、ポイント２の下面２１の方がダイ３の上面３１よりも隆起する高さが高い。この塗布装置１でも貫通孔２２、３２に近づくにつれてポイント２の下面２１とダイ３の上面３１との距離が短くなっている。貫通孔２２、３２の近くでは、ポイント２の下面２１は貫通孔２２に向かって下向きとなり、ダイ３の上面３１は貫通孔３２に向かって上向きとなるが、ポイント２の下面２１の隆起が急激であるために、ポイント２の下面２１およびダイ３の上面３１からの距離が等しい仮想面８は線条体５に近づくにつれて下向きとなる。 The coating apparatus 1 shown in FIG. 13 is the same as FIGS. 11 and 12 in that the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are shaped to rise as they approach the through holes 22 and 32. However, contrary to the coating device shown in FIG. 12, the lower surface 21 of the point 2 has a higher height than the upper surface 31 of the die 3. Also in this coating apparatus 1, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 becomes shorter as it approaches the through holes 22 and 32. Near the through holes 22, 32, the lower surface 21 of the point 2 faces downward toward the through hole 22, and the upper surface 31 of the die 3 faces upward toward the through hole 32. Therefore, the virtual surface 8 having the same distance from the lower surface 21 of the point 2 and the upper surface 31 of the die 3 becomes downward as it approaches the filament 5.

図１４に示す塗布装置１では、ポイント２の下面２１、ダイ３の上面３１とも、それぞれ外縁から貫通孔２２、３２に向かって隆起しているが、貫通孔２２、３２の直近で平面となっている。このポイント２とこのダイ３とを組み合わせた塗布装置１では、ポイント２およびダイ３の外縁からポイント２の貫通孔２２またはダイ３の貫通孔３２に向かってポイント２の下面２１とダイ３の上面３１との距離が短くなり、貫通孔２２、３２の直近では前記距離は一定である。これもポイント２の下面２１とダイ３の上面３１との距離が変動する例である。 In the coating apparatus 1 shown in FIG. 14, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are raised from the outer edge toward the through holes 22 and 32, respectively, but are flat in the immediate vicinity of the through holes 22 and 32. ing. In the coating apparatus 1 in which the point 2 and the die 3 are combined, the lower surface 21 of the point 2 and the upper surface of the die 3 from the outer edge of the point 2 and the die 3 toward the through hole 22 of the point 2 or the through hole 32 of the die 3. The distance to 31 is shortened, and the distance is constant in the immediate vicinity of the through holes 22 and 32. This is also an example in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies.

図１５に示す塗布装置１では、ポイント２の下面２１は図３に示すポイントと同様に、外縁近くおよび貫通孔２２近くでは平面であり、その中部で隆起している。ダイ３の上面は３１は外縁近くおよび貫通孔３２近くでは平面であり、その中部で沈降している。この塗布装置１では、ポイント２の下面２１の貫通孔２２近くの平面２１ａがダイ３の上面３１の貫通孔３２近くの平面３１ａよりも小さい。これによりポイント２の下面２１が隆起しつつある部分２１ｂにダイ３の上面３１の平面部３１ａが向き合う部分で、ポイント２の下面２１とダイ３の上面３１との距離は貫通孔に近づくにつれて短くなる。図１５における平面部２１ａ、３１ａの幅や隆起しつつある部分２１ｂまたは沈降しつつある部分３１ｂの幅を変更すると、ポイント２の下面２１とダイ３の上面３１との距離を径方向に変動させることができ、径方向にそって見たときに、ある部分では一定、ある部分では徐々に長く、ある部分では徐々に短くすることができる。 In the coating apparatus 1 shown in FIG. 15, the lower surface 21 of the point 2 is a plane near the outer edge and near the through hole 22, as in the point shown in FIG. 3, and is raised at the center. The upper surface 31 of the die 3 is a flat surface near the outer edge and near the through hole 32, and sinks in the middle thereof. In the coating apparatus 1, the plane 21 a near the through hole 22 on the lower surface 21 of the point 2 is smaller than the plane 31 a near the through hole 32 on the upper surface 31 of the die 3. Thereby, the flat portion 31a of the upper surface 31 of the die 3 faces the portion 21b where the lower surface 21 of the point 2 is raised, and the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 becomes shorter as it approaches the through hole. Become. When the width of the flat portions 21a and 31a and the width of the protruding portion 21b or the sinking portion 31b in FIG. 15 are changed, the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is varied in the radial direction. When viewed along the radial direction, it can be constant in some parts, gradually longer in some parts, and gradually shorter in some parts.

図２ないし図１５に示した塗布装置では、線条体の軸を含む断面で見て、ポイントとダイの隙間が外縁から線条体に向かって徐々に狭くなる箇所がある。そこで線条体に向かう樹脂の流れが絞られるので、樹脂の塗布性が向上する。 In the coating apparatus shown in FIGS. 2 to 15, there is a portion where the gap between the point and the die gradually narrows from the outer edge toward the linear body when viewed in a cross section including the axis of the linear body. Therefore, since the resin flow toward the striatum is narrowed, the resin applicability is improved.

本発明の第二形態では、線条体に樹脂を塗布する塗布装置において、ポイントの下面およびダイの上面からの距離が等しい仮想面が前記線条体に垂直な面でないような前記ポイントと前記ダイとを組み合わせて配置する。 In the second embodiment of the present invention, in the coating apparatus for applying a resin to the striatum, the virtual surface having the same distance from the lower surface of the point and the upper surface of the die is not a surface perpendicular to the striatum, and the point Place in combination with the die.

図１６に示す塗布装置では、ポイント２の下面２１は貫通孔２２の近くで貫通孔３２に向かって沈降する形状であり、ダイ３の上面３１は平面となっている。このポイント２とこのダイ３とを組み合わせると、ポイントの下面およびダイの上面からの距離が等しい仮想面が貫通孔に近づくにつれてもち上がり、線条体に垂直な面ではない。また、この塗布装置は、ポイント２の下面２１とダイ３の上面３１との距離が変動する例でもある。 In the coating apparatus shown in FIG. 16, the lower surface 21 of the point 2 has a shape that sinks toward the through hole 32 near the through hole 22, and the upper surface 31 of the die 3 is a flat surface. When this point 2 and this die 3 are combined, a virtual surface having the same distance from the lower surface of the point and the upper surface of the die rises as it approaches the through hole, and is not a surface perpendicular to the striatum. This coating apparatus is also an example in which the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 varies.

図１７に示す塗布装置１では、ポイント２の下面２１、ダイ３の上面３１は、線条体５の軸を含む断面（図１７に示す断面）において、それぞれ外縁から貫通孔２２、３２にかけて直線となる形状であり、ポイント２の下面２１とダイ３の上面３１との距離は一定である。ポイント２の下面２１は外縁から貫通孔２２に向かって沈降し、ダイ３の上面３１は外縁から貫通孔３２に向かって隆起する。ポイント２の下面２１およびダイ３の上面３１が同じ円錐台の斜面をなすポイント２とダイ３を組み合わせることにより図１７の塗布装置１が構成される。ポイントの下面およびダイの上面からの距離が等しい仮想面８も同じ円錐台の斜面となり、線条体５に垂直な面ではない。ポイントの下面とダイの上面との隙間は外縁から線条体５に向かって上向きとなっている。 In the coating apparatus 1 shown in FIG. 17, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are straight lines extending from the outer edge to the through holes 22 and 32 in the cross section including the axis of the filament 5 (cross section shown in FIG. 17). The distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is constant. The lower surface 21 of the point 2 sinks from the outer edge toward the through hole 22, and the upper surface 31 of the die 3 rises from the outer edge toward the through hole 32. The coating apparatus 1 of FIG. 17 is configured by combining the die 2 with the point 2 where the lower surface 21 of the point 2 and the upper surface 31 of the die 3 form the same truncated cone. The virtual surfaces 8 having the same distance from the lower surface of the point and the upper surface of the die are also inclined surfaces of the same truncated cone, and are not surfaces perpendicular to the linear body 5. The gap between the lower surface of the point and the upper surface of the die is directed upward from the outer edge toward the filament 5.

図１８に示す塗布装置１では、ポイント２の下面２１、ダイ３の上面３１は、線条体５の軸を含む断面（図１８に示す断面）において、それぞれ外縁から貫通孔２２、３２にかけて直線となる形状であり、ポイント２の下面２１とダイ３の上面３１との距離が一定である点では図１７と同様である。しかし、図１７とは逆に、ポイント２の下面２１は外縁から貫通孔２２に向かって隆起し、ダイ３の上面３１は外縁から貫通孔３２に向かって沈降する。この塗布装置１も、ポイント２の下面２１およびダイ３の上面３１が同じ円錐台の斜面をなすポイント２とダイ３を組み合わせることにより構成される。ポイントの下面およびダイの上面からの距離が等しい仮想面８も同じ円錐台の斜面となり、線条体５に垂直な面ではない。ポイントの下面とダイの上面との隙間は外縁から線条体５に向かって下向きとなっている。 In the coating apparatus 1 shown in FIG. 18, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are straight lines extending from the outer edge to the through holes 22 and 32 in the cross section including the axis of the filament 5 (the cross section shown in FIG. 18). 17 in that the distance between the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is constant. However, contrary to FIG. 17, the lower surface 21 of the point 2 protrudes from the outer edge toward the through hole 22, and the upper surface 31 of the die 3 sinks from the outer edge toward the through hole 32. This coating apparatus 1 is also configured by combining the point 2 and the die 3 in which the lower surface 21 of the point 2 and the upper surface 31 of the die 3 form the same truncated cone slope. The virtual surfaces 8 having the same distance from the lower surface of the point and the upper surface of the die are also inclined surfaces of the same truncated cone, and are not surfaces perpendicular to the linear body 5. A gap between the lower surface of the point and the upper surface of the die faces downward from the outer edge toward the linear body 5.

図１８に示す塗布装置１では、仮想面８が下向きであるので線条体５の進行方向に樹脂６が速やかに流れる。ポイントの下面とダイの上面との隙間が若干絞られるとなお樹脂の塗布性が向上する。一方、図１７に示すように仮想面８が貫通孔の近くで上向きになると、塗布された樹脂の外径が均一、表面がなめらかであったり、樹脂の偏肉がないまたは樹脂中に気泡がないなど樹脂の塗布性がよい。例えば、ポイントとダイの間隔、樹脂圧その他の条件を同一として、ポイントとダイとの隙間の向きだけを異ならせて樹脂被覆線条体を製造すると、図１７に示すように線条体に向かって上向きに２０度とする場合は、図１８に示すように下向きに２０度とする場に比べて、樹脂中の気泡が混入する異常が見られる頻度は１割ほどよくなる。 In the coating apparatus 1 shown in FIG. 18, since the virtual surface 8 faces downward, the resin 6 flows quickly in the traveling direction of the filament 5. If the gap between the lower surface of the point and the upper surface of the die is slightly narrowed, the resin applicability is improved. On the other hand, when the virtual surface 8 faces upward near the through hole as shown in FIG. 17, the outer diameter of the applied resin is uniform, the surface is smooth, there is no uneven thickness of the resin, or there are bubbles in the resin. Good resin applicability. For example, if a resin-coated linear body is manufactured with the same distance between the point and die, resin pressure, and other conditions, but only the direction of the gap between the point and the die is different, the direction toward the linear body is as shown in FIG. When the angle is set to 20 degrees upward, as shown in FIG. 18, the frequency of occurrence of an abnormality in which bubbles in the resin are mixed is improved by about 10% compared to the case where the angle is set to 20 degrees downward.

図１９に示す塗布装置１では、ポイント２の下面２１、ダイ３の上面３１は、それぞれ外縁から貫通孔２２、３２に向かって中部まで一定の幅で平面である。貫通孔２２、３２の近くでは、線条体５の軸を含む断面（図１９に示す断面）において、直線となる形状であり、ポイント２の下面２１の距離とダイ３の上面３１の距離は一定である。ポイント２の下面２１は貫通孔２２の近くでは貫通孔２２に向かって沈降し、ダイ３の上面３１は貫通孔３２の近くでは貫通孔３２に向かって隆起する。ポイント２の下面２１の沈降部２１ｃおよびダイ３の上面３１の隆起部３１ｃが同じ円錐台の斜面をなすポイント２とダイ３を組み合わせることにより図１９の塗布装置１が構成される。ポイント２の下面２１およびダイ３の上面３１からの距離が等しい仮想面８は平面と円錐台の斜面の組み合わせとなり、線条体５に垂直な面ではない。そして、仮想面８が貫通孔の近くで上向きになっている。 In the coating apparatus 1 shown in FIG. 19, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are flat with a constant width from the outer edge toward the through holes 22 and 32 to the middle. In the vicinity of the through holes 22 and 32, the cross section including the axis of the filament 5 (the cross section shown in FIG. 19) has a straight shape, and the distance between the lower surface 21 of the point 2 and the distance between the upper surface 31 of the die 3 is It is constant. The lower surface 21 of the point 2 sinks toward the through hole 22 near the through hole 22, and the upper surface 31 of the die 3 protrudes toward the through hole 32 near the through hole 32. The coating apparatus 1 of FIG. 19 is configured by combining the die 2 and the point 2 where the sinking portion 21c of the lower surface 21 of the point 2 and the raised portion 31c of the upper surface 31 of the die 3 form the same truncated cone. The virtual surface 8 having the same distance from the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is a combination of a flat surface and an inclined surface of a truncated cone, and is not a surface perpendicular to the filament 5. The virtual surface 8 faces upward near the through hole.

図２０に示す塗布装置１では、ポイント２の下面２１、ダイ３の上面３１は、それぞれ外縁から貫通孔２２、３２に向かって一定の幅で平面であって、貫通孔２２、３２の近くでは、線条体５の軸を含む断面（図２０に示す断面）において、直線となる形状であり、ポイント２の下面２１の距離とダイ３の上面３１の距離は一定である点では図１９と同様である。しかし、図１８とは逆にポイント２の下面２１は貫通孔２２の近くでは貫通孔２２に向かって隆起し、ダイ３の上面３１は貫通孔３２の近くでは貫通孔３２に向かって沈降する。ポイント２の下面２１の隆起部２１ｄおよびダイ３の上面３１の沈降部３１ｄが同じ円錐台の斜面をなすポイント２とダイ３を組み合わせることにより図２０の塗布装置１が構成される。ポイント２の下面２１およびダイ３の上面３１からの距離が等しい仮想面８は平面と円錐台の斜面の組み合わせとなり、線条体５に垂直な面ではない。 In the coating apparatus 1 shown in FIG. 20, the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are flat with a constant width from the outer edge toward the through holes 22 and 32, respectively, and near the through holes 22 and 32. In the cross section including the axis of the filament 5 (the cross section shown in FIG. 20), the shape is a straight line, and the distance between the lower surface 21 of the point 2 and the distance between the upper surface 31 of the die 3 is constant as shown in FIG. It is the same. However, contrary to FIG. 18, the lower surface 21 of the point 2 rises toward the through hole 22 near the through hole 22, and the upper surface 31 of the die 3 sinks toward the through hole 32 near the through hole 32. The coating device 1 of FIG. 20 is configured by combining the point 2 and the die 3 where the raised portion 21d on the lower surface 21 of the point 2 and the settling portion 31d on the upper surface 31 of the die 3 form the same truncated cone. The virtual surface 8 having the same distance from the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is a combination of a flat surface and an inclined surface of a truncated cone, and is not a surface perpendicular to the filament 5.

図２１に示す塗布装置１では、ポイント２の下面２１は中部が隆起している。ダイ３の上面３１は中部が沈降して貫通孔にかけて隆起していてかつ外縁にかけて隆起している。線条体５の軸を含む断面（図２１に示す断面）において、ポイント２の下面２１およびダイ３の上面３１はそれぞれ同半径の円弧である。このポイント２とダイ３とを組み合わせてなる塗布装置１では、ポイント２の下面２１の距離とダイ３の上面３１の距離は一定である。ポイント２の下面２１およびダイ３の上面３１からの距離が等しい仮想面８はポイント２の下面２１およびダイ３の上面３１と同じ曲面となり、線条体５に垂直な面ではない。そして、仮想面８が貫通孔の近くで上向きになっている。 In the coating apparatus 1 shown in FIG. 21, the lower surface 21 of the point 2 has a raised middle portion. The upper surface 31 of the die 3 has a central portion that sinks and rises toward the through hole and rises toward the outer edge. In the cross section including the axis of the filament 5 (the cross section shown in FIG. 21), the lower surface 21 of the point 2 and the upper surface 31 of the die 3 are arcs of the same radius. In the coating apparatus 1 formed by combining the point 2 and the die 3, the distance between the lower surface 21 of the point 2 and the distance between the upper surface 31 of the die 3 is constant. The virtual surface 8 having the same distance from the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is the same curved surface as the lower surface 21 of the point 2 and the upper surface 31 of the die 3 and is not a surface perpendicular to the linear body 5. The virtual surface 8 faces upward near the through hole.

図２ないし図６、図８ないし図１０、図１２、図１３、図１５および図１６に示した塗布装置もポイントの下面とダイの上面からの距離が等しい仮想面が線条体に垂直な面ではないので、これらの例は本発明の第一形態であると同時に第二形態でもある。例えば、図１６に示した塗布装置１では、ポイント２の下面２１およびダイ３の上面３１から等しい距離にある仮想面８が貫通孔２２、３２近くで上向きとなる。ここで、樹脂の塗布性が向上する。 2 to 6, FIG. 8 to FIG. 10, FIG. 12, FIG. 13, FIG. 15 and FIG. 16, the imaginary plane having the same distance from the lower surface of the point and the upper surface of the die is perpendicular to the filament. Since these are not planes, these examples are the first form of the present invention as well as the second form. For example, in the coating apparatus 1 shown in FIG. 16, the virtual surface 8 that is at an equal distance from the lower surface 21 of the point 2 and the upper surface 31 of the die 3 faces upward near the through holes 22 and 32. Here, the applicability of the resin is improved.

図７、図１１および図１４に示す塗布装置は、ポイント２の下面２１とダイ３の上面３１とからの距離が等しい仮想面に対して面対称の形状であるときには第二形態ではないが、それ以外の場合は第一形態であると同時に第二形態である。 The coating apparatus shown in FIGS. 7, 11, and 14 is not in the second form when the shape is plane-symmetric with respect to the virtual plane where the distance from the lower surface 21 of the point 2 and the upper surface 31 of the die 3 is equal, Otherwise, it is the first configuration and the second configuration.

本発明では図２ないし図２１に例示した被覆装置などを使用して、ポイント２とダイ３の隙間に樹脂６を供給して、その樹脂６に線条体５を通過させて線条体に樹脂を塗布する。続けて樹脂６０が塗布された線条体を硬化装置に通し、樹脂６０が紫外線硬化型樹脂の場合は硬化装置４内で樹脂６０に紫外線を照射し、あるいは樹脂６０が熱硬化型樹脂の場合は硬化装置４内で樹脂６０に熱を加えて、樹脂６０を硬化させて樹脂被覆線条体を製造する。本発明では、樹脂と線条体とが接する箇所とポイント下面との線条体の長さ方向の距離を５ｍｍ以内とすることができる。この距離は、ポイントとダイとの隙間の形状を変更することにより数ｍｍの範囲で調整可能である。 In the present invention, the coating device illustrated in FIGS. 2 to 21 is used, and the resin 6 is supplied to the gap between the point 2 and the die 3, and the linear body 5 is passed through the resin 6 to form the linear body. Apply resin. Subsequently, the linear body to which the resin 60 is applied is passed through a curing device. When the resin 60 is an ultraviolet curable resin, the resin 60 is irradiated with ultraviolet rays in the curing device 4, or when the resin 60 is a thermosetting resin. Applies heat to the resin 60 in the curing device 4 to cure the resin 60 to produce a resin-coated filament. In this invention, the distance of the length direction of the linear body of the location where resin and a linear body contact | connect, and a point lower surface can be made into 5 mm or less. This distance can be adjusted within a range of several mm by changing the shape of the gap between the point and the die.

図２ないし図２１では、ダイが一つのもののみ示したが、図２２に示すようにダイが二段構成になっており、ポイント２０と第一ダイ３０の間に第一樹脂６１を供給し、第一ダイ３０と第二ダイ４０の間に第二樹脂６２を供給して、塗布装置１１を通過するときに第一樹脂６１および第二樹脂６２を同時に塗布する場合にも、本発明は有効である。 2 to 21 show only one die, the die has a two-stage configuration as shown in FIG. 22, and the first resin 61 is supplied between the point 20 and the first die 30. Even when the second resin 62 is supplied between the first die 30 and the second die 40 and the first resin 61 and the second resin 62 are simultaneously applied when passing through the coating device 11, the present invention is It is valid.
