Intermittent reinforcement fiber sheet placement is part of manufacturing high quality
composite components (especially carbon fiber reinforcements). In producing mul tiaxial
layer reinforcement textiles or in the filament winding process, the reinforcement fibers are
subjected to special dynamic conditions during fiber placement. These con ditions are
disadvantageous for achieving high quality composite components. There fore, a device is
required for feeding twist-free fiber sheets with a constant low fiber tension level, which
can be fitted to a filament winding machine or a warp knitting machine with a multiaxial layer
weft insertion system. Solutions for twist-free inter mittent reinforcement fiber sheet
placement for composite applications can only be realized by complex and expensive
mechanical feeding devices. Thus, a new tangential creel has been developed, consisting
of a rolling bobbin draw-off frame and a tension reducing accumulator, fulfilling the complex
dynamic requirements of composite com ponent production.
