A system for debundling fiber tow into chopped fibers is provided that has one or more reels of fiber tow, a cutting element configured to receive the fiber tow to form chopped fiber, and a tube with introduced gas flow configured to receive the chopped fiber. A moving belt is positioned under the tube to collect the chopped fiber. A dispenser is positioned along the moving belt for applying a binder or additive. A treatment chamber receives the treated chopped fiber. A process for debundling fiber tow into chopped fibers is provided that supplies one or more reels of fiber tow to a cutting system, drops the chopped fiber into a tube with introduced gas flow to debundle the chopped fiber with a vortex, collects the chopped fiber exiting the tube onto a moving belt, chemically treats the chopped fiber, and provides the chemically treated chopped to a treatment chamber.

A reel changing device is described for reeling fiber bundles from a fiber strand exiting a spinning device, including at least a first reel carrier and a second reel carrier on each of which a reel suited for winding up the fiber strand is arranged and which are movably received and guided in at least a first reel guide and a second reel guide so that the reels are adapted to be positioned one after another in an exit direction of the fiber strand so as to enable, in the case of a reel change, the fiber strand to be directly transferred from the first reel arranged on the first reel carrier to the second reel arranged on the second reel carrier. Moreover, a reel changing method in such reel changing device is described.
