ABSTRACT:
This invention relates to an improved wheel rim rolling apparatus for use in producing a vehicle wheel rim. The wheel rim rolling apparatus includes a top roll assembly having upper rim tools adapted to engage a rim blank or a partially formed rim in order to impart a desired shape thereto, a moveable member and a non-moveable member. The upper rim tools are carried by the moveable member. A first position indicating member is attached to one of the moveable member and the non-moveable member of the top roll assembly. The first position indicating member is operative to generate a visual or readable output signal which is used for determining the position of the upper rim tools of the top roll assembly. A second position receiving member is attached to the other one of the moveable member and the non-moveable member of the top roll assembly. The second member is adapted to receive the visual or readable output signal from the first member to thereby indicate the position of the upper rim tools.
