【発明の詳細な説明】
本発明は繊維状ガラスファイバ（以下線材と呼ぶ）の表
面にプラスチックを塗布するだめのプラスチック被覆装
置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plastic coating device for applying plastic to the surface of a fibrous glass fiber (hereinafter referred to as a wire).
従来、この種のプラスチック被覆装置は一つの被覆装置
において膜厚を決めるだめのダイス開口部を一つしか有
していなかったため以下の欠点を有していた。Conventionally, this type of plastic coating apparatus has had the following drawbacks because one coating apparatus has only one die opening for determining the film thickness.
すなわち、１）被覆装置内を通過する線材の速度が数百
メートルにも達すると、プラスチックの塗布層が附かな
いことがある、２）塗布層が薄くなる、３）塗布層が不
均一である、４）一様な塗布層が得られない。Namely, 1) when the speed of the wire passing through the coating device reaches several hundred meters, the plastic coating layer may not be applied, 2) the coating layer becomes thin, and 3) the coating layer is uneven. , 4) A uniform coating layer cannot be obtained.
本発明はこれらの欠点を除去するためプラスチック液溜
め内にプラスチック整流開口部を設けたもので、以下図
面について詳細に説明する。The present invention eliminates these drawbacks by providing a plastic rectifying opening within the plastic reservoir, and will be described in detail below with reference to the drawings.
第１図は本発明の一実施例、すなわち、液溜め内にプラ
スチック整流開口部を有する２分割型のプラスチック被
覆装置の説明図である。FIG. 1 is an explanatory diagram of one embodiment of the present invention, that is, a two-part plastic coating device having a plastic rectifying opening in the liquid reservoir.
１は線材，２は本体，３は被覆用のプラスチツ久，４は
同筒状のプラスチック整流開口部，５は仕上ダイス開口
部，６は液溜め，７は被覆線材である。1 is a wire rod, 2 is a main body, 3 is a plastic tube for coating, 4 is a cylindrical plastic rectifying opening, 5 is a finishing die opening, 6 is a liquid reservoir, and 7 is a coated wire rod.
この本体は２分割であるため、走行する１０線材にダイ
ス開口部が一致するように設置されている。Since this main body is divided into two parts, it is installed so that the die opening matches the 10 running wire rods.
次にこの装置を操作するには、先づ３のプラスチックを
供給し、５の開口部によって塗布する。To then operate the device, first feed the plastic at 3 and apply it through the opening at 5.
４の整流開口部は５の開口部に比べて大きく、６の液溜
め内のプラスチックの流れに方向性をもだせ、プラスチ
ックを塗布しやすくするもので５によって所定の厚さに
仕上げる。The rectifying opening 4 is larger than the opening 5, giving directionality to the flow of the plastic in the liquid reservoir 6, and making it easier to apply the plastic.
第２図は本発明の他の実施例の説明図であって、第１図
の４の開口部の代わりに整流開口部としてフエルト板に
よる塗布部を設けたものである。FIG. 2 is an explanatory diagram of another embodiment of the present invention, in which an application section made of a felt plate is provided as a rectifying opening in place of the opening 4 in FIG. 1.
８は支持棒，９は調整ねじ，１０はフエルト板，５は仕
上げダイス開口部，６は液溜めである。8 is a support rod, 9 is an adjustment screw, 10 is a felt plate, 5 is a finishing die opening, and 6 is a liquid reservoir.
この装置を操作するには走行する１の線材に２の本体を
セットした後、１０のフエルト板ヲ、９の調整ねじによ
って８の支持棒を移動させて開口間隔を調整する。To operate this device, after setting the main body 2 on the running wire 1, the opening interval is adjusted by moving the felt plate 10 and the support rod 8 using the adjusting screw 9.
次いで３のプラスチックを供給して塗布する。Next, supply and apply the plastic of 3.
第３図は本発明の他の実施例の説明図であって、第１図
における４の整流開口部の代りに１対のローるを用いた
ものである。FIG. 3 is an explanatory diagram of another embodiment of the present invention, in which a pair of rows are used in place of the four rectifying openings in FIG. 1.
１１がロールである。ロールは本実施例においては回転
式であって、走行線材の速度とほぼ等しい周速で回転す
る。11 is a roll. In this embodiment, the roll is rotary, and rotates at a circumferential speed approximately equal to the speed of the running wire.
ロールは場合により静止しているものや、片方のみが回
転するものなどを用いる。Depending on the case, a stationary roll or a roll with only one side rotating may be used.
ロールによる開口部はＵ溝，Ｖ溝などをロールの片方も
しくは両方に切って形成される。The openings in the rolls are formed by cutting U-grooves, V-grooves, etc. in one or both of the rolls.
各実施例に共通な利点、すなわち本発明の効果は、１つ
の被覆装置において線材は複数のダイス開口部を通過し
て塗布されるため、線材の走行速度が毎分百メートル以
上の高速に達しても安定した均一な膜厚を確保すること
ができることである。The advantage common to each of the embodiments, that is, the effect of the present invention, is that in one coating device, the wire is coated by passing through a plurality of die openings, so that the running speed of the wire can reach a high speed of 100 meters per minute or more. It is possible to ensure a stable and uniform film thickness even when the film is coated.
線材走行軸の複数個のダイス開口部の種類を連続的にか
えることによって上記効果を増大することができる。The above effect can be enhanced by continuously changing the types of the plurality of die openings on the wire rod running shaft.
第１図は本発明の一実施例である、１つのプラスチック
整流ダイス開口部としての仕上げダイス開口部とを有す
