Abstract: To provide a plating removing apparatus for 3-piece wheels, which can easily and neatly remove plating at the welding planned portion of the superimposed part of the inner rim and the outer rim. A plating removing apparatus that removes plating of a welding planned portion R in a three-piece wheel having the inner rim 2B, the outer rim 2A, and a disk, comprises a support means 11 that rotatably supports the outer rim 2A, at least three holding rollers 34 that hold the rim supported by the support means 11 from the outer circumferential side, a rotation drive means 67 that rotates and drives the outer rim 2A held by the holding rollers 34, and a grinding means that grinds the welding planned portion R on the outer circumferential surface of the rim 2A by an abrasive cloth/paper 13 and removes plating the welding planned portion R.

Abstract: To provide a plating removing apparatus for 2-piece wheels, which can easily and beautifully remove plating at the welding planned portion on the rim inner circumferential surface and achieves 2-piece wheels with rims plated without requiring any troublesome operation, said apparatus comprising a pair of support rollers 13 horizontally arranged, a positioning member 15 that positions the rim 2 in the axial direction of the support roller 13, a pair of holding rollers 19 that hold the rim 2 between the support rollers 13 and the holding rollers 19, a rotation drive means that rotates and drives the rim 2 held between the support rollers 13 and holding rollers 19, and a grinding means that extends to an inside of the rim 2 for grinding the welding planned portion RW of the rim 2 with respect to the disk, and for removing plating of the relevant welding planned portion.

Abstract: The present invention provides a wheel and manufacturing method of the same which make it possible to prevent the formation of indentations along the hump parts in the inner circumferential surface of the rim. In a wheel which comprises a cylindrical rim consisting of a rolled metal plate, and in which hump parts that are used to lock the inner circumferential edge part of the tire are disposed circumferentially so that these hump parts protrude to the outside in the vicinity of the end part of the outer circumferential surface of the rim on at least the design surface side, the outer hump part is formed to have an increased thickness by damming so that this outer hump part protrudes outward while the inner circumferential surface of the rim that corresponds to the outer hump part is formed into a flat circumferential surface.
