A circulating conveyor may comprise: a first conveying line and a second conveying line, wherein both the first conveying line and the second conveying line have a loading position and an unloading position at the two ends and clamps may be circularly conveyed between the first conveying line and the second conveying line in a clockwise or counterclockwise direction; and a circulating adapter. The circulating adapter may comprise a first circulating adapter and a second circulating adapter arranged in pairs at both the loading position and the unloading position, wherein the first circulating adapter and the second circulating adapter may be used for conveying the clamps between the first conveying line and the second conveying line.

A container feeding system for transporting a container along a transport path from a container source to a container receiver. The container feeding system includes a carrier for receiving and transporting the container, a pulling element connected to the carrier in such a way that the carrier can be moved along the transport path, a guide arranged along the transport path for guiding the carrier along the transport path. The carrier is arranged at the guide in such a way that the carrier can be moved by the pulling element in a sliding manner along a first surface of the guide.

A conveyor system for transporting items from a receiving section to an outlet section includes a plurality of assemblies for carrying and transporting the items and a driving system. The driving system is configured to move the plurality of support assemblies from the receiving section to the outlet section. The driving system includes an endless chain of concatenated riving rods that are mutually hingedly connected, and an actuator for moving the endless chain of driving rods. Each support assembly is connected to a respective rod to be moved thereby in the transport direction. The actuator has a frame with two wheels that engage with the endless chain of concatenated rods. One of the wheels is a driving wheel driven by a motor. The actuator with the frame and wheels is mounted to the conveyor system such that it is movable substantially transversely to the transport direction.
