The precursor industry, such as unloading of Polyacrylonitrile (PAN) tow for a carbon fibre oxidation & carbonisation line, is continuously trending towards larger loads in a single package. The leading creel technology for this industry is Cygnet Texkimp’s unique design for unwinding large packages of delicate material and multi-filaments from precision cross-wound cheeses. The layout of these large creels is designed over multiple levels to minimise their foot print and offering bespoke configurations. Integrated robotics and handling equipment is often included to minimise process down time and eliminates fibre damage during loading.
Cygnet Texkimp offer both mechanical and fully driven electrical tension control. The mechanical system allows the lowest possible running tension from a non-driven system whilst maintaining full control of the unwinding tow. The fully driven system allows low and fixed tensions which are unaffected by package diameter, weight or process speeds.
Another variant of the precursor creel is the Cygnet Texkimp box creel system, which consists of a mechanical guiding and control system to allow precursors to be unloaded from bulk containers.
While the industry trend is towards larger packages for longer run times, Cygnet Texkimp maintains a family of creel products to suit a wide range of package sizes. These products are often used for smaller tow count precursors or in pilot scale production and testing facilities.
