<p>Movement of rollers (214) used for reforming an inner wall (124) of a metal container bottom such as an aluminum beverage container is controlled at least partially using a rigid link (222) coupled to other components of a reformer apparatus by a pin having a stepped profile. The stepped-profile pin preferably defines first and second shoulder regions. Undesired spaces or gaps in the pin-axial or thrust direction are reduced or eliminated by closely-positioning bushing flanges or thrust washers adjacent the shoulders.</p> |
