Abstract
A scroll shaping drum useful in the construction of tires and including an internal air cylinder having an inner sleeve member and a roller member positioned about the inner sleeve member includes a plurality of cam follower assemblies anchored within the inner sleeve member. Each cam follower assembly includes a hub and a cam follower member positioned about the hub, and the cam follower member of each assembly is accepted by an appropriately-shaped slot defined in the roller member. The inner sleeve member defines an internally-threaded opening for accepting the hub of each assembly, and each hub includes a mounting portion positioned within a corresponding internally-threaded opening of the inner sleeve member. In addition, an externally-threaded insert member having a length which is larger than the thickness of the wall of the inner sleeve member is threadably accepted by the internally-threaded opening of the inner sleeve member and has a central through-opening within which the mounting portion of the hub is force-fitted.
