Abstract
A mechanical conveyor system is provided with an exposed flexible membrane surface for use in clean room environments. 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.
