System for releasably attaching a shell segment to a core section of a drum useful in the manufacture of vehicle tires. The system includes an outwardly opening longitudinal groove in the outer surface of the core section and a like groove in inner surface of the shell segment. These grooves are designed to overlie one another and cooperatively define a channel when the segment is positioned in overlying relationship to the core section. An actuator/slide/wedge/stop combination is disposed with the channel. The relationship to the actuator and the slide/wedge/stop combination is such that activation of the actuator acting upon the slide causes the slide to move longitudinally within its groove, engage the wedge and urge the wedge initially in a generally longitudinal direction along the channel until its longitudinal movement is halted by the stop, whereupon further longitudinally directed force exerted by the slide against the wedge causes the wedge to move laterally of the channel to frictionally engage the side edges of the core section groove and/or the side edges of the shell segment groove to align the shell segment with respect to the core section and to releasably anchor the shell segment to the core section. Upon deactivation of the actuator, the slide is freed to move longitudinally of the channel, thereby releasing the wedge and releasing the shell segment. In a preferred embodiment, the shell segment is divided into two pieces, e.g. halves, and there is provided a slide/wedge/stop block combination for releasably attaching each of the half-segments to a single core section. A method for releasably attaching a first member to a second member, such as shell segments to a core section of a vehicle tire-making drum, is disclosed.
