Abstract
A tire building drum is disclosed having first and second sets of deck segments, disposed in an alternating configuration about a central shaft. Each of the segments is mounted to a pair of axially movable hub units via an associated scissor linkage. The scissor linkages of the first segments are slidably mounted to the hub units and biased toward a median plane of the tire building drum. When the hub units are separated, the second segments are disposed radially inwardly of and between the first segments. Movement of the hub units toward one another through a first range of motion expands the first deck segments to an expanded diameter of the drum, and movement of the hub units toward one another through a second range of motion expands the second deck segments to allow the second deck segments to be received between the first deck segments.
