摘要： A buffer conveyor (1) comprises a frame and a drivable endless conveyor belt (4) which successively follows a transport path from an input station (2) to an output station (3) and a return path from the output station (3) to the input station (2). The lengths of the transport path and the return path are inversely adjustable. At the transport path the frame is provided with two parallel transport path frame legs (5, 5', 6, 6') and a U-shaped transport path bridge (13). The transport path bridge (13) includes a curved bridge portion (17) and parallel bridge legs (18) extending from the curved bridge portion. The transport path bridge (13) is displaceable along the transport path frame legs. Within the transport path the conveyor belt (4) successively follows from the input station (2) one of the transport path frame legs (5, 5'), one of the bridge legs, the curved bridge portion, the other one of the bridge legs and the other one of the transport path frame legs (6, 6') to the output station (3). Each of the transport path frame legs is provided with a transport path frame guide (25) for supporting a lateral contact side (27) of the conveyor belt (4) in outward direction as seen from the other transport path frame leg. The transport path bridge (13) is shaped such that along the curved bridge portion (17) and respective twisted regions (18b) of the bridge legs (18) adjacent to the curved bridge portion (17) the conveyor belt (4) has a transverse down-slope towards the inside of the U-shape and such that the lateral contact side (27) of the conveyor belt (4) at said twisted regions (18b) is above the respective transport path frame guides (25).
