Each polishing band 30 is rotated by a driving motor 36 so as to be fed from bottom to top at different speeds. Therefore, the pachinko balls taken between the lower ends of the respective polishing bands 30 are lifted up while being held while being held between the polishing bands 30 which are closely opposed to each other as the polishing bands 30 rotate. . At this time, since the polishing bands 30 are rotationally driven at different speeds from each other, the surface of pachinko balls held between the polishing bands 30 is even.
It is transported while rolling frequently so that it contacts 0 and is polished.

Each of the polishing bands 30 is formed by appropriately selecting one of the group consisting of nylon 6, nylon 66, etc., as described above, and therefore has the same characteristics as those of conventional nylon belts. Compared with this, dust such as cotton dust is hardly generated in the polishing and conveying process, and durability is improved. Further, it is possible to obtain elasticity, strength, abrasion resistance, heat resistance and peculiar advantages in terms of cost based on the individual characteristics of the various nylon resins described above.

The dirt adhering to the pachinko balls being conveyed is transferred to the surface of each polishing band 30 and scraped off by being rubbed by the edges of the numerous slit holes 31, 32 of the polishing band 30. , Pachinko balls are polished more fully and evenly.
Most of the dirt removed from the pachinko balls is discharged to the back side of the polishing band 30 through the slit holes 31 and 32 without excessively fixing on the surface of the polishing band 30.

When the polished pachinko balls are conveyed to the island upper end 10A, they are supplied to the upstream end of the distribution trough 16 from the discharge port 23 in the upper part of the housing 21 and again to each pachinko machine 1.
