4 is a first gold roll made of metal that supplies paint to the application roll 2; and 4 is a second gold roll made of metal that supplies paint to the first gold roll 3. The coating roll 2 includes an annular cylindrical portion 21 that contacts the body 11 of the can body 1 and an annular conical portion 22 that contacts the inclined surface 12 of the can body 1. The second gold roll 4 includes an inner cylinder part 31 and an annular inverted conical part 32 that contact the inner cylinder part 21 and the annular conical part 22, respectively, and the second gold roll 4 is connected to the inner cylinder part 31 and the inverted conical part 3 of the first gold roll 3.
2, a cylindrical portion 41 and an annular conical portion 42 contacting each other.
It is equipped with The seamless can body 1, coating roll 2, first gold roll 3, and second gold roll 4 rotate in opposite directions and are in contact with each other.

現象さえ見られたのである。 For coating, firstly, paint is supplied to the second gold roll 4, and then the first gold roll 3, coating roll 2,
The paint is transferred to the seamless can body 1. The reason why two gold rolls are used here is that if only one is used, the paint can be evenly applied to the annular cylindrical part 2 of the roll 2.
This is because it becomes difficult to transfer the paint to the inner tube of the gold roll, and on the other hand, if three or more are used, there is a greater possibility that the paint will stick to the inner cylinder of the gold roll. However, even when using two metal rolls, if a gold roll with a conical part 42 or an inverted conical part 32 as shown in FIG. 2 is used, due to the discrepancy in circumferential speed, The paint cannot be uniformly transferred from the annular conical portion 42 of the second gold roll 4 to the annular inverted conical portion 32 of the first gold roll 3, and therefore, the paint cannot be uniformly transferred to the annular conical portion 22 of the applicator roll 2. The paint cannot be transferred, and as a result, uneven coating occurs on the inclined surface 12 of the seamless can body 1. In fact, if this uneven coating occurs and is extremely severe, the paint may even stick to the annular inverted conical portion 32 of the first gold roll 3 and the annular conical portion 42 of the second gold roll 4. It was.

又、装置が複雑になつて、品質管理、装置の保守
管理に多大な労力を要求され、好ましくない。 There is also a technique of painting the can body and the sloped surface using separate application rolls, but in that case, the application roll for the body and the application roll for the slope are separate, so after painting, may cause boundaries,
Moreover, the apparatus becomes complicated and a great deal of effort is required for quality control and maintenance of the apparatus, which is undesirable.

いた。 FIG. 3 shows an example of the device of the present invention. 1 is the first
It is the same seamless can body as shown in the figure, and 6 is a cylindrical metal first gold roll, and 7 is a cylindrical metal second gold roll. 5 is the first gold roll 6
is a coating roll placed between the can body 1 and the body 11 of the can body 1 on the outside of the metal roll shaft 51.
the annular cylindrical portion 52 in contact with the inclined surface 1 of the can body 1;
It has an outer layer of elastic material with a deformable annular conical portion 53 that contacts 2. Note that 55 is a large diameter annular cylindrical portion following the annular conical portion 53, but it is not necessarily an essential element. Therefore, the annular cylindrical portion 52
The material is not particularly limited to these, but butyl rubber or nitrile rubber is selected from among those that have a swelling rate of 40% or less with respect to the paint and solvent used, and a hardness of 30° to 50° according to a type A rubber hardness meter. It was used as Further, the annular conical portion 53 and the large-diameter annular cylindrical portion 55 are made of sponge material, and their outer portions 54 are covered with a rubber material. Various materials can be used as the sponge material, but in this example, ethylene is selected from those with a swelling rate of 40% or less against the paint and solvent used and a hardness of 10° or less on a C-type rubber hardness tester. Propylene rubber was selected and used. This annular conical part 53 contacts the inclined surface of the can body 1, but as can be seen from the figure, when the annular cylindrical part 52 contacts the first gold roll 6, it presses against the first gold roll 6. The gold roll is deformed and comes into close contact with the gold roll. In this regard, if the ethylene propylene rubber has a thickness of 25 mm to 50 mm in the annular conical portion 53, it can be sufficiently restored even if it is compressed and deformed by the first gold roll.
The rubber material of the outer portion 54 has a swelling rate of 40% or less with respect to the paint and solvent used, has a rubber hardness of about 15° to 10° on an A-type rubber hardness tester, and has a thickness of 0.5 mm or more.
Approximately 1 mm is sufficient, but in this example, the hardness is 13° and the thickness is 1 mm.
butyl rubber was used. Note that the annular cylindrical portion 52 and the annular conical portion 53 were bonded together using a suitable adhesive.

ではない。 According to the present invention, when the applicator roll 5 comes into rotational contact with the first gold roll 6, the annular conical part 53 (and the large diameter cylindrical part 55) is compressed by the first gold roll 6 and loses its original shape. 6, and on the other hand, when it comes into contact with the inclined surface 12 of the can body, it has returned to its original shape, so that the body 11 and the inclined surface 12 of the can body 1 can be coated simultaneously and evenly. Even from the standpoint of the gold roll, since the annular conical portion of the applicator roll is deformed, there is no need to provide the conical portion 42 or the inverted conical portion 32 as shown in the second figure. Disadvantages when there are are avoided.
In addition, since the lengths of the first gold roll 6 and the second gold roll 7 are longer than the length of the applicator roll 5 as described above, the paint is also reliably transferred to the annular conical portion of the applicator roll 5. Note that the large diameter cylindrical portion 55 is provided to prevent the annular conical portion 53 from deforming during operation at very high speeds, and is not always required.

and the following large-diameter annular cylindrical portion 85,
A notch 84 having an apex within the annular conical portion 83 and opening toward the large diameter annular cylindrical portion 85 is provided. 82 is an annular cylindrical portion that comes into contact with the straight body portion 11 of the can body 1. The cutout portion 84 of this embodiment is
It has a triangular cross-sectional shape due to the annular inner conical part 86 having a line parallel in cross section to the outer surface of the annular conical part 83 and the inner cylindrical part 87 concentric with the large diameter annular cylindrical part 85 . However, the shape of this notch is not necessarily limited to a triangular cross section, but may be any shape that can be compressed and deformed into close contact with the first gold roll 6, for example, a trapezoid as shown in FIG. The notch 84' may also be used.
