Abstract
A drum is provided for building a green tire casing. The drum includes sectors, an expander, and an adjuster. The sectors form a circumferential face of the drum. The expander moves the sectors in a radial direction such that, at any given time, all the sectors extend at a same distance from an axis of the drum. The adjuster moves the sectors in the radial direction separately from movement of the sectors caused by the expander. Movement of the sectors by the adjuster is such that, at any given time, all the sectors extend at an equal distance from the axis of the drum. The expander is usable to move the sectors regardless of a position of the sectors caused by an operation of the adjuster.
