Abstract: Conveyor for transporting an object particularly for use in a system which treats objects while they are continuously in motion. The conveyor is made up of carriers which are combined with other carriers to form an endless chain for carrying the objects to be treated from one work station to another. Each carrier is connected to a similar carrier with at least a degree of freedom of turning of one carrier with respect to its neighbor or neighbors about the longitudinal axis of the conveyor chain whereby the conveyor can be gradually twisted or turned to be inverted in its travel. Each carrier is provided with a housing having guides for retaining an object within the carrier.
