。For example, container lids, such as crowns, are generally made entirely of ultra-thin sheets (e.g. tin sheets,
It is formed by punching a chromic acid-treated steel sheet or aluminum-based alloy sheet into a desired shape, and then simultaneously or subsequently applying press working or the like. In the container lid formed in this manner, the required amount of protective coating is applied to the outer and inner surfaces, but the cut edge (the edge R produced by the above-mentioned punching) is coated with a protective coating. There is no protective coating and the metal material is exposed. Therefore, as is well known to those skilled in the art, if a container lid formed in the above-described manner is plugged into the bottom of a container such as a beverage bottle, it will take a relatively short period of time, especially in high humidity conditions. Over time, rust will develop on the cut edge, making it unacceptable from the point of view of appearance and hygiene. Therefore, conventionally, after forming the container lid as described above, Attempts have been made to apply a rust preventive agent to the cut edge as a protective coating. As a painting method of applying a rust preventive to the cut edge of a container lid, for example, as disclosed in Japanese Patent Publication No. 55-16240, the container lid is fixedly held by an appropriate retainer, and then the container is fixedly held. transporting the lid through a predetermined path and dipping its cut edge into a layer of electrocoated paint;
It has thus been proposed to electrocoat the cut edges.

べき種々の欠点が存在する。However, known painting methods including the above-mentioned electrodeposition coating for applying a rust preventive to the cut edge of a container lid require (1) application of the rust preventive agent sufficiently uniformly over the entire cut edge; (2) Requires relatively complex and expensive equipment;
(3) It is impossible or difficult to speed up the painting process; (4)
) There is a strong tendency for the rust preventive agent to weakly adhere to parts other than the cut edge of the container lid, and such weakly adhered rust preventive agent may fall off during the subsequent capping process and contaminate the capping machine, etc. There are various drawbacks that need to be resolved.

。Then, when the container lid 86 is conveyed through the processing area 88''!, the cut edge of the container lid 86 is brought into partial contact with the surface of the article processing belt 20.This point will be explained in more detail as follows.
As can be easily understood from FIG. 2, in the specific example shown, the processing running portion 48a of the article conveying belt 48 (i.e., the front side in FIG. 1, the second The surface of the rollers 66 and 68/fi article processing belt 20 around which the article conveyance belt 48 is wound is such that the surface of the running section (located on the left side in the figure and the rear side in FIG. 3) forms an acute angle α. It is sloped. Therefore, in the non-processing traveling portion 48b of the article conveying belt 48, there is a relatively large gap between the lower edge of the article conveying belt 48 and the surface of the article processing belt 20, but the article conveyance in the processing area 88 is The lower edge of the processing running portion 48 & of the belt 48 and the article processing belt 2
The interval between 0 and 0 is relatively small. Additionally, in the illustrated embodiment, as can be easily understood from FIG. The lower edge of the processing run m4sa of the article conveying belt 48 in the processing area 88 is tilted at an appropriate angle β in the direction of gradually approaching the surface of the article conveying belt 48. The surface of the article processing belt 20 is sequentially approached when viewed in the direction. Therefore, the container lid 86, which is suctioned and held on the surface of the article conveying belt 48 so that its cut edge partially protrudes downward beyond the lower edge of the article conveying belt 48, is On the upstream side of the processing zone 88 in the direction of movement of the belt 48 shown by the arrow 74, the cut edge does not come into contact with the surface of the article processing belt 20, but when the article is conveyed to the processing zone 88, The cut edge will come into contact with the surface of the article processing belt 20. In the processing area 88 , the surface of the article conveying belt 48 is attracted by the action of a magnetic field generated by a stationary guide plate 22 formed from a permanent magnet disposed on the back surface of the upper traveling section 201 of the article processing belt 20 . The retained container lid 86 is magnetically attracted to the surface of the article processing belt 20, thus ensuring that the cut edge of the container lid 86 is in partial contact with the surface of the article processing belt 20.

It is convenient for the traveling path of the article conveying belt 48 (i.e., the processing traveling section 48 of the article conveying belt 48) to extend at an angle r, preferably about 3 to 40 degrees, particularly about 5 to 20 degrees. It is. When the running path of the article conveying belt 48 is inclined at the angle r with respect to the running path of the article processing belt 20 in the processing area 88, as can be easily understood by referring to FIG. The container lid 86 is prevented from rolling obliquely over an area of the surface of the article handling belt 20 having a relatively large lateral width W, and therefore has a relatively large lateral width W of the surface of the article handling belt 20. The rust preventive agent present in the area having @W is effectively used and is sufficiently applied to the cut edge of the container lid 86. On the other hand, if the angle r is 0 degrees or a significantly small value, the container lid 86 in the processing area 88 will roll only over a specific region of the surface of the article processing belt 200 where the width in the lateral direction is significantly small. Otherwise, there is a risk that the rust preventive agent transferred from the surface of the article processing belt 20 to the cut edge of the container lid 86 may be insufficient.
