Abstract
A top roll exchanging apparatus for a rim shape forming machine. The top roll exchanging apparatus includes a movable bearing device for supporting a top roll shaft and a top roll loading/unloading arm provided on an extension of the top roll shaft. The movable bearing device is movable between an engaging position wherein the movable bearing device rotatably supports the top roll shaft and a waiting position wherein the movable bearing device is spaced from the extension of the top roll shaft. The top roll loading/unloading arm is movable toward and away from the top roll shaft and is rotatable about a mid-portion thereof. A top roll is exchanged by removing the movable bearing device from the engaging position, moving the top roll loading/unloading arm to load and unload top rolls and finally returning the movable bearing device to its original position.
