Abstract
A core or a core shaft is formed from a plurality of identical, extruded pieces. Each piece has complementary grooves on opposite sides, so that the pieces interlock. Each piece extends the length of the core or core shaft. The pieces are held together by a series of pins and are connected to a core shaft journal or a core cap by a series of screws that fit into receptacles in the pieces. When used as a core shaft, each piece includes a channel for a bladder.
