1. A multi-piece roller for a conveyor belt, comprising:
- first and second roller sections that fit together to form a complete roller with an outer periphery between opposite ends;
the first and second roller sections together defining a bore extending along the central axis of the roller and opening onto the opposite ends for receiving an axle, wherein the bore is formed in part by each of the first and second roller sections;
at least one first interdigitating member on the first roller section and at least two second interdigitating members on the second roller section that interdigitate with each other for assembling the two sections by sliding the two sections together in a direction perpendicular to the central axis of the complete roller, wherein the interdigitated first and second interdigitating members prevent axial separation of the first and second roller sections;
wherein each of the at least one first interdigitating members and each of the at least two second interdigitating members spans the bore.

Abstract
Multi-piece rollers for a conveyor belt. First and second roller sections fit together to form a complete roller. The two roller sections together define a bore for receiving an axle. The bore and the periphery of the roller are formed in part by each of the first and second roller sections. The roller is assembled by sliding the two sections together in a direction perpendicular to the axle with the bore closing around the axle. The roller sections have fingers that interdigitate with each other to prevent axial separation of the first and second roller sections. The interdigitated fingers surround a majority of the bore.
