て自由に回転するように構成する。Example 1 An example of the present invention will be described below based on the drawings. As shown in FIG. 1, the outer peripheral surface forming roll 5
is divided into a central forming roll 9 for forming the drop portion 6 of the rim 1, and outer forming rolls 10, 10 for forming the bead seat 7 and flange portion 8, and the outer forming rolls 10, 10 are each formed through a bearing 11. It is configured so that it can rotate freely.
また、内周面成形ロール１２は一体成形ロール
とするか、分割してもピン・キー等で以て一体化
するものとする。 Further, the inner circumferential surface forming roll 12 may be an integrally formed roll, or even if it is divided, it may be integrated using pins, keys, etc.
実施例 ２
第２図に示すように、外周面成形ロール１３は
一体成形ロールとするか、分割しても一体化する
ものとする。Embodiment 2 As shown in FIG. 2, the outer circumferential surface forming roll 13 is an integrally formed roll, or even if it is divided, it is integrated.
内周面成形ロール１４はリム１のドロツプ部６
