ABSTRACT:
Principal movable elements are mounted for displacement on a first rolling track and coupled together in pairs by a flexible link of constant length. Auxiliary movable elements are mounted for displacement on a second rolling track. The spacing between the first and second rolling track is variable along at least a part of the path of travel. Each flexible link passes over two deflecting members each mounted integrally on one of the principal movable elements. A central portion of each flexible link is always positioned substantially in the direction of displacement and the two extreme portions of each link are respectively secured to an auxiliary movable element without rigid part between a principal and an auxiliary element.
