ABSTRACT:
An expandable tire building drum is provided with hinged drum shoulder segments that present, when the drum is in its expanded position, a bevelled shoulder contour for supporting the thickened portion of the tire band next to the bead. This bevelled contour results in a greater radius of curvature for the thickened tire portion that extends around the drum shoulder, which makes it easier to pass a stitcher wheel over this portion of the tire, and to achieve a more uniform layering of the tire components next to the bead of the tire. When the drum is in its retracted position, the hinged drum shoulder segments are lifted to positions wherein they provide support for the carcass plies of the tire when they are first laid across the drum segments and the bead turnover bladders.
