A curved conveyor section (20, 220) comprises a generally flat substantially horizontally disposed curved belt-supporting bed (30, 230) having first and second opposite ends (31, 32, 231, 232) and first and second direction reversing members (35, 36, 235, 236) disposed at the first and second opposite ends, respectively. A continuous loop curved conveyor belt (40, 240) has arcuate inner and outer edges (42, 44, 242, 244) with a common substantially vertical centre axis ("A", "I") and is mounted on the belt-supporting bed in looped relation around the direction reversing members so as to have an article carrying portion (46, 246) disposed above the belt-supporting bed and a return portion disposed below the belt-supporting bed, thus defining a looped path for the conveyor belt and presenting a substantially horizontal article carrying top surface (46t, 246t). A motor driven continuous loop drive chain or belt (70, 270, 100, 110) is oriented in a substantially horizontal plane and has a plurality of driving members (72, 272) disposed along its looped length. A plurality of driven receptors (60, 260) are securely mounted on the curved conveyor belt along its looped path. The driving members drivably engage a consecutive subset of the plurality of cooperating receptors, which consecutive subset is disposed at one of the article carrying portion and the return portion of the curved conveyor belt, so as to thereby impart a driving force to the co-operating receptors, thus causing selective movement of the curved conveyor belt along its looped path.
