The conveyor system may be one of varied subassemblies which transfer articles on the conveyor by small orbital motions. The exposed flexible sheath is preferably a membrane which is permeable to air. The system may provide for air flow through the membrane to ensure a clean environment. A preferred flexible membrane is expanded polytetrafluoroethylene.
