Abstract

The invention relates to a conveyor device which is used to transport work-pieces, especially the work-pieces of motor vehicle bodies, through a processing area for surface treatment of said work-pieces, comprising a conveyor which brings the work-pieces which are respectively maintained by a holder into the processing area; transports them through said area and removes them therefrom. The inventive conveyor device requires less maintenance in comparison with known conveyor devices. The holders respectively comprise a base part which moves in a translatory movement along a conveyor device and a rotating part on which the work-piece is arranged and which is held in such a way that it is rotatable on the base part. The conveyor comprises at least one drive device enabling at least one directly driven respective holder to be driven directly in a movement along the conveyor device. The movement of the directly driven holder is transferred to an indirectly driven holder as a result of the contact between the directly driven holder and said at least one indirectly driven holder.
