Abstract: A process for automatically forming optical shuffles, which included providing a plurality of spools are provided, which are each formed from at least one fiber. The free ends of the fibers are led up to a winding device and fixed to the latter in such a way that the fibers can be wound onto it in one and the same winding direction and lying approximately parallel to one another. The sections of the fibers coming from the spool are combined with one another in groups to form ribbons. A first length section of each ribbon is unwound from the associated spool and wound onto the winding device (input side of the shuffle). After the length section has been unwound, the spools or fiber-guiding devices connected downstream of the spools are reorganized, so that, in a direction running transversely with respect to the unwinding direction, the outgoing fibers assume different positions relative to one another than before.
