本発明は、帯状フィルム、紙、布或いはこれらの複合物
、加工物等（以下ウェブと称す）のジヨイント部の塗工
方法とこの方法に直接使用する装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for coating joint portions of film strips, paper, cloth, composites thereof, processed products, etc. (hereinafter referred to as webs), and an apparatus directly used in this method. be.
現在、帯状処理物たるウェブの塗工は、ロール外周面の
１個所又は数個所にエツジ部を有するコンマ型ドクター

膜を形成させて行なっている。Currently, coating of a web, which is a strip-shaped product, is carried out by running the web between a backing hanger and a comma-shaped doctor knife that has edges at one or several locations on the outer peripheral surface of the roll.
During the passage, a coating film is formed on the surface using the doctor knife.
ところで、樹脂液が塗工されるウェブ°には他の部位よ

がそれを目視して該ジヨイント部の前後部分（約５〜１
０ｍ）にわたってドクターナイフを上方ジャンピングさ
せ、通過するとドクターナイフを元の位置に復元させて
樹脂液の塗工を続行していた。Incidentally, the web to which the resin liquid is coated has a joint part that is thicker than other parts, but when the joint part of the web passes through a doctor knife when coating the web, the joint part is not attached to the doctor knife. Conventionally, when the joint part of the web approaches the doctor knife, the operator visually checks the front and rear parts of the joint part (approximately 5 to 1
The doctor knife was made to jump upward over a distance of 0 m), and when it had passed, the doctor knife was returned to its original position and the coating of the resin liquid was continued.
しかしながら、これによると、ウェブが切れる等のトラ

て塗工量が急速に増加し、通常量の２〜５倍塗工される
。However, although this method can prevent problems such as web breakage, the gap between the web and the doctor knife increases while the doctor knife is jumping upwards, causing resin liquid to flow out. As the amount increases, the amount of coating increases rapidly over the front and rear portions of the joint, and is coated 2 to 5 times the normal amount.
これが為、塗工量の多いジヨイント部の前後部分を後工
程たる乾燥工程において乾燥処理する場合は、ウェブを
大幅にスピードダウンさせるか或いは一定量以上の塗工
液を排除する必要があり、作業性がきわめて悪かった。For this reason, when drying the front and rear parts of the joint part, where a large amount of coating is applied, in the subsequent drying process, it is necessary to significantly slow down the web or remove more than a certain amount of coating liquid. The sex was extremely bad.
そして、かような作業によってもなお完全に乾燥しない
場合があり、その結果様々の不都合が生じていた。Even with such operations, there are cases where the product is not completely dried, resulting in various inconveniences.
また、上記ドクターナイフをジャンピングさせると、ド
クターナイフのジャンピング前後において塗工量の不均
一が生じ復元性が悪くなる場合があり、問題があった。Further, when the doctor knife is jumped, there is a problem in that the amount of coating becomes non-uniform before and after the jump of the doctor knife, resulting in poor restorability.

処理速度を低下させることなく、且つ樹脂液の塗工量を
常に一定に維持し得るウェブのジヨイント部塗工方法と
装置を提供せんとするものである。Furthermore, unless the supply of resin liquid is stopped and the coating is applied between the front and rear joints of the web, the above-mentioned problem will not occur, but this will not allow continuous processing of the web and will reduce workability. In view of the above points, the present invention is
It is an object of the present invention to provide a method and apparatus for coating joint portions of a web, which can maintain a constant coating amount of resin liquid without reducing processing speed.

This is a detection means that detects in advance the joint portion 7 of the running web 6. This is a detection means that, for example, a gage roller 24 is attached in a hanging manner to a shift loss gauge 28 supported by an appropriate means, and the roller 24 is mounted in a hanging manner. The movement of the roller 24 is measured by the thickness gauge 2.
3, the detected signal is converted and amplified into an electrical signal, and the air cylinder 14 is actuated based on the operation signal derived from the thickness gauge 23. It is configured to rotate by a predetermined angle in the direction of the arrow shown in the figure at or near the same speed.

ムーズに通過する。In this way, just before the joint portion 7 of the web 1 passes, the doctor knife 1' rotates and its arcuate surface 1' faces the packing roll 4, so the doctor knife 1 functions as a squeezing roll. As a result, the joint part 7
passes smoothly between the arcuate surface 1' and the packing roll 4 without being caught by the edge portion 2 of the doctor knife 1.
こうしてウェブ１が通過すると、直ち、にエアシリンダ
１４のピストンロツ１１６が自動的に伸長し、アームプ

液が塗工されることなくスムーズに通過する。In this way, the joint part γ of the blade is aligned with the doctor knife 1.
When passing between the and packing roll 4, the doctor knife 1 rotates and functions as a squeezing roll as described above, so that the joint part γ and its front and rear parts are not coated with more coating liquid than necessary. pass smoothly.
第４図は本発明の他の実施例を示したもので、上記実施
例と同一部分は同一符号で示す。FIG. 4 shows another embodiment of the present invention, in which the same parts as in the above embodiment are designated by the same reference numerals.

ができる。In addition, the amount of resin liquid applied to the web 6 is determined by the doctor knife 1.
The amount of coating varies depending on the set angle of the edge portion 2, so the amount of coating can be adjusted by moving the protrusion 21 forward and backward by appropriately rotating the manual bundle 20 of the stopper device 19, and pressing the protrusion 21 with the piston rod 15. This can be done by adjusting the position of the arm plate 13.
また、上記の各実施例では、ウェブ６のジヨイント部１

よい。Further, in each of the above embodiments, the joint portion 1 of the web 6
When passes through doctor knife 1, doctor knife 1
However, a device for jumping the doctor knife 1 was attached, and depending on the physical properties of the web 6, the jumping device could cause the doctor knife 1 to jump a minute amount in synchronization with the rotation operation. Good too.
更に、上記実施例では、ドクターナイフ１の回転はエア

限定されるわけではなく、例えば手動でドクターナイフ
１を回転させてもよい。Further, in the above embodiment, the doctor knife 1 is rotated using the air cylinder 14, but the present invention is not limited to this, and the doctor knife 1 may be rotated manually, for example.
本発明は上述の様に構成したから、ウェブのジヨイント
部には必要以上の樹脂液が塗工される様なことはなく、
樹脂液の塗工量を常にほぼ一定に維持することができる
。Since the present invention is configured as described above, there is no possibility that more resin liquid than necessary is applied to the joint portion of the web.
The amount of resin liquid applied can always be maintained almost constant.
また、上記ジヨイント部の通過時には、ドクターナイフ
が、ナイフ効果ではなく絞りロールとして機能するので
、ジヨイント部はドクターナイフとパツキングロール間
をスムーズに通過する。Furthermore, when passing through the joint, the doctor knife functions as a squeezing roll rather than a knife effect, so the joint passes smoothly between the doctor knife and the packing roll.
しかも、ジヨイント部の通過時、ドクターナイフをジャ
ンピングさせる必要がない為、ウェブが通過する間隙が
変化することはなく、精度を通常運転と同一状態に維持
することができる。Moreover, since there is no need to jump the doctor knife when passing through the joint, the gap through which the web passes does not change, and the accuracy can be maintained at the same level as in normal operation.
したがって、従来の如くジヨイント部の通過のたびに特
別な運転方法或いは処理の必要がなく、種々のトラブル
発生が防止され、且つ処理速度を低下させることなくウ
ェブの連続処理が可能となり、作業性の大幅な向上を図
ることができる。Therefore, there is no need for special operating methods or processing every time the web passes through the joint, unlike in the past, various troubles are prevented, and the web can be processed continuously without reducing processing speed, improving work efficiency. Significant improvements can be made.
