<p>On processing machines for web- or sheet-like materials, devices for positioning carriages along guides are known, which have as drive means a revolving band extending parallel to the guides. Each carriage has a movable element for coupling to the drive means. …<??>According to the invention, the coupling element is arranged between the two sides (18, 19) of the band and it contains means (piston ends 16, 17) for alternate coupling to both sides (18, 19).
