Abstract:
A redirect device that guides composite material tows along a fiber path from a material supply creel to a fiber placement head within a fiber placement assembly during a composite material forming process, the device comprising:(a) a frame assembly;(b) a plurality of outer swivel roller assemblies operatively connected to the frame assembly, wherein the outer swivel roller assemblies are configured to direct and contain fiber tows, and minimize tow friction caused by changes in the fiber path, the outer roller assemblies being rotatable about respective axes independently of each other;(c) a plurality of inner swivel roller assemblies operatively connected to the frame assembly, wherein the inner swivel roller assemblies are configured to minimize tow friction caused by changes in the fiber path;whereby each of the material tows follows a tow routing arrangement along a fiber path from the material supply creel, engaging an outer swivel roller assembly, engaging an inner swivel roller assembly, and traveling into the fiber placement head.
