ABSTRACT:
The invention relates to a curved assembly line and/or conveyor belt, especially for assembling and transporting motor vehicles or motor vehicle parts during production, said line or belt being formed by articulated carrier elements that positively engage in each other and respectively comprise an upper platform and a lower carrier frame and have convex and concave front surfaces with identical curvature radii. The aim of the invention is to enable an essentially tangential orientation of the platforms in the curved region with a simple course of displacement and low control costs. To this end, respective carrier elements (2) with concave (9) and convex front surfaces (6,7) on both sides alternate in the longitudinal direction of the assembly line and/or conveyor belt (1), and the respective carrier elements (2) with concave front surfaces (9) on both sides are embodied as short intermediate elements (8) which are located between the carrier elements (2) receiving the load and have convex front surfaces (6,7) on both sides.
