いる。[0003] The cutting edge of the coating head H is liable to be abraded by hard dispersed particles made of inorganic substances contained in the coating liquid during the coating in a state of being in sliding contact with the coating liquid for a long time. It is easily corroded by various additives such as resin and solvent therein. When such abrasion and corrosion progress, the coating conditions change, and the uniformity of the thin layer is lost, so that smooth and highly accurate coating becomes impossible. For this reason, as shown in the first prior art, the back edge 2 and the doctor edge 3 are optimized so that the shape of the cutting edge at the tip and the opening width of the slot 1 increase wear resistance. , Second
As shown in the prior art, a hard metal having a Co content of 15% by weight or less is used for the cutting edge to improve the wear resistance and the corrosion resistance.

And so on. In particular, this problem was remarkable at the front end of the back edge which is located on the upstream side of the traveling flexible belt-shaped support and is easily subjected to a large force such as an impact during coating.

A first member and a second member arranged in order along the direction in which the flexible band-shaped support member travels, and the first member and the second member are disposed between the first member and the second member. A slot through which the coating liquid flows toward the flexible belt-shaped support is formed, and the coating liquid flows out from an outlet of the slot opened at the end of the member, and is applied to the flexible belt-shaped support. The tip of the first member and the tip of the second member are formed of a cemented carbide, and the hardness H1 of the tip of the first member and the hardness of the tip of the first member are determined. The relationship with the hardness H2 of the tip of the second member is H1 <H2.

もに、刃先の破損を防止することができる。[0007] With this configuration, the bending force at the tip of the first member located on the upstream side in the traveling direction of the flexible belt-like support member is enhanced, and the cutting edge when a large force such as an impact is applied is applied. Of the second member, which is located downstream of the flexible belt-shaped support in the running direction and is in sliding contact with the coating liquid, is improved in wear resistance. The tip of the first member located on the upstream side in the traveling direction of the flexible belt-shaped support,
Because it receives frictional force from the flexible belt-like support and tensile force due to the coating liquid flowing out of the slot, it is compared with the tip of the second member located downstream of the flexible belt-like support in the running direction. Therefore, it is easy to receive a large force such as an impact at the time of application. On the other hand, the tip of the second member located on the downstream side in the traveling direction of the flexible belt-shaped support is located behind the first member and does not receive much frictional force from the flexible belt-shaped support. Instead,
Compared to the tip of the first member, the first member is always exposed to the flowing coating solution, and thus is more susceptible to wear and corrosion by the coating solution. Accordingly, by setting the hardness H1 at the tip of the first member to be smaller than the hardness H2 at the tip of the second member and setting the relationship to H1 <H2, the bending force at the tip of the first member is increased. At the same time, the abrasion resistance of the tip of the second member is enhanced, whereby the bending force and the abrasion resistance of the entire application head are enhanced.
In this way, it is possible to impart wear resistance to the cutting edge of the coating head and to prevent breakage of the cutting edge.

And the difference H2-H1 between the hardness H2 of the tip of the second member and

平滑かつ高精度で塗布される。With such a configuration, it is possible to prevent a difference in progress of wear between the tip of the first member and the tip of the second member. If the hardness of the distal end of the first member is too small, the distal end of the first member will wear faster than the distal end of the second member. The properties and uniformity are lost, making it impossible to apply a thin layer with high precision. For this reason, when the difference between the hardness of the tip of the first member and the hardness of the tip of the second member is represented by the difference of the Rockwell hardness A scale defined by the JIS standard, H2−H1 ≦ H if they meet the condition of R A3, the first member of the tip wear rate and a second next approximately the same wear rate of the tip of the member, a thin layer on a flexible strip support smooth and accurately Applied.

る。In addition, the hardness H1 of the first member tip 15 is smaller than the hardness H2 of the second member tip 16 and H1 <H2, so that the bending resistance of the first member tip 15 is increased, and The wear resistance of the second member tip 16 is enhanced, and the bending force and wear resistance of the coating head 10 as a whole are enhanced. The first member tip 15 located on the upstream side in the traveling direction of the flexible belt-shaped support 14 receives a frictional force from the flexible belt-shaped support 14, a pulling force by the coating liquid flowing out of the slot 13, and the like. Therefore, compared to the second member tip 16 located on the downstream side in the traveling direction of the flexible belt-shaped support 14, the second member tip 16 is more likely to receive a large force such as an impact at the time of application. On the other hand, the second member tip 16 located on the downstream side in the running direction of the flexible belt-shaped support
Is located behind the first member tip 15 and does not receive much frictional force from the flexible band-shaped support 14,
As compared with the member tip 15, the coating liquid is always exposed to the flowing coating liquid, so that it is susceptible to wear and corrosion by the coating liquid. Therefore,
When the hardness H1 of the first member tip 15 and the hardness H2 of the second member tip 16 satisfy H1 <H2, wear resistance is imparted to the cutting edge of the coating head 10 and bending resistance is increased. Further, chipping and chipping and other defects of the cutting edge are prevented.

In this way, a smooth, uniform, and highly accurate thin layer is applied on the flexible belt-like support 14.
