Abstract
In an arrangement in which a group of roller chains packed closely together, side by side, in a manner in which they can advance independently of each other, with the chains advancing parallel to each other in common plane in one area and the chains leaving the common plane at one point and thereafter following separate paths and then coming together again at an entry point for the common plane, guides are provided to prevent adjacent roller chains from running up on to each other as they return to the common plane.
