て供給する塗工液供給装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coating liquid supply device for a coating machine, and more specifically, the present invention relates to a coating liquid supply device for a coating machine. The present invention relates to a coating liquid supply device for supplying a coating liquid to a running continuous belt-like object such as a film, cloth, paper, or thin plate.
フィルム、布帛、紙、薄板等の連続状帯状物の上に樹脂
等の溶液を塗工する塗工機としては、従来より種々の方
式のものが知られている。BACKGROUND ART Various types of coating machines have been known for coating a solution of resin or the like onto a continuous strip such as a film, fabric, paper, or thin plate.
、例えば、第6図に示すように、連続状帯状物を保持及
び走行させるパツキングロール(112>、ロール周面
の一部にエツジを有する塗工液調整のためのドクタナイ
フ(11B)よりなるドクタ式塗工機が知られている。For example, as shown in FIG. 6, there is a packing roll (112) for holding and running a continuous strip, and a doctor knife (11B) for adjusting the coating liquid having an edge on a part of the roll circumferential surface. Type coating machines are known.

液ダム式となっていた。In this coating machine, a packing roll (
It is a liquid dam type in which a liquid reservoir (124) for the coating liquid (111) is provided by a dam plate (127) in the part where the continuous strip (110) is inserted between the doctor knife (ite) and the doctor knife (ite). Ta.

させることにより行なっていた。With this liquid dam type, the coating liquid (l i 1 ) pumped from the coating liquid supply unit (not shown) is transferred to the liquid reservoir (124).
and was supplied to the upper surface of the continuous strip (110) from the opening at the bottom of this liquid reservoir (124). The supply of the coating liquid (ill) to the continuous strip (110) has been stopped by stopping the supply of the coating liquid (ill) from the coating liquid supply section.
[発明が解決しようとする課題]
ところで、フィルム、布帛、紙、薄板等の連続状帯状物
の繋ぎ目部分は重ね合わせとなって他の部分より厚いた
め、この繋ぎ目部分に塗工液を塗工すると連続帯状物が
さらに厚くなり、ドクタナイフとパツキングロールとの
間に連続帯状物を挿通される時に連続帯状物が切れるお
それがある。そのため、連続帯状物の繋ぎ目部分は未塗
工にすることが望ましい。[Problems to be Solved by the Invention] By the way, the joints of continuous strips such as films, fabrics, paper, thin plates, etc. overlap and are thicker than other parts, so it is difficult to apply a coating liquid to these joints. When coated, the continuous strip becomes even thicker, and there is a risk that the continuous strip will be cut when it is inserted between the doctor knife and the packing roll. Therefore, it is desirable to leave the joint portions of the continuous strip uncoated.

熟練を要した。However, in the liquid dam type coating liquid supply means described above, even if the supply of the coating liquid (ill) is stopped, the coating liquid (111) remains in the liquid reservoir (124). Therefore, it was not possible to form an uncoated portion in the width direction of the continuous strip (110) unless all of the remaining coating liquid (111) was discharged. Therefore, the continuous strip (1
10), it was difficult and required skill to form uncoated portions in the width direction of the continuous strip, such as the joint portions desired by the operator.
