An articulated conveyor comprising a conventional endless-loop chain-link conveyor belt traveling over a fixed frame section, an adjustable frame section mounted for translational movement on a guide carrier, and a floating frame section pivotably mounted to connect the fixed section to the adjustable section. The guide carrier permits translational movement of the adjustable frame section in a direction perpendicular to the longitudinal axes of the adjustable frame section and the fixed frame section to provide parallel offset of the adjustable section with respect to the fixed section. Longitudinal guide slots in the upper and lower faces of the three frame sections engage center tabs on the bottom of the belt to guide the belt for travel along the frame sections. As the adjustable frame section is translatably offset, variable radius guides slidably mounted between the three frame sections permit the belt to turn through a smooth and continuous arc rather than having to turn sharply about a fixed pivot point, thereby avoiding the limitations imposed by the minimum possible turn radius inherent in the design of the chain-link conveyor belt.
