Cygnet Texkimp has raised the efficiency benchmark in carbon fibre production with the launch of its new 500kg Very Heavy Duty (VHD) PAN precursor unwinding creel. The system accommodates bobbins at 500kg — significantly above the 350kg standard that has defined the industry for more than a decade — and delivers measurable gains in line continuity for composite manufacturers worldwide.
Breaking the 350kg Barrier in Carbon Fibre Handling
For over ten years, packages weighing up to 350kg set the practical ceiling for carbon fibre precursor unwinding equipment. Cygnet Texkimp's new VHD creel resets that limit by accommodating polyacrylonitrile (PAN) precursor bobbins at 500kg. The larger package size directly reduces how often operators must stop production lines for changeovers.
Fewer changeovers mean less downtime and more consistent throughput. For high-volume manufacturers, even modest extensions to continuous run length compound into substantial annual productivity gains.
Peter Stevenson, Director of Projects at Cygnet Texkimp, explained the commercial impact: "A 500kg bobbin offers an immediate win over a 350kg bobbin in terms of line efficiency by extending the length of continuous operation that can be achieved. The creel also supports the work of manufacturers to process higher tow count fibres, such as 24k or 48k tows, and achieve faster line speeds by increasing the size and weight of the PAN precursor bobbin."
Technical Design: Tension Control and Loading Mechanism
The new creel features an operator-controlled lifting and loading mechanism that transfers PAN precursor packages from the winding system directly to the creel position. For operations requiring greater automation, Cygnet Texkimp offers customised material-handling solutions configured to specific production environments.
Like the company's existing VHD range, the 500kg creel incorporates an electronic tension control system with a closed-loop dancer arm mechanism. This technology maintains consistent fibre tension throughout the full unwinding cycle, supporting stable processing conditions, higher line speeds, and improved product quality across advanced composite applications.
The system's compatibility with 24k and 48k tow count fibres gives manufacturers the flexibility to scale both fibre weight and throughput speed without compromising process stability.
Cygnet Texkimp's Global Footprint in Carbon Fibre Equipment
Cygnet Texkimp has built a leading position in VHD creel technology, with more than 70 installations operating worldwide. Collectively, these systems process over 24,000 fibre bobbins, serving carbon fibre producers across multiple international markets.
Stevenson noted the development was driven by sustained industry consultation and a global increase in carbon fibre production capacity. The new creel addresses high-volume industrial applications, including those established to create new sovereign manufacturing capability in key markets.

Frequently Asked Questions
Why is moving from 350kg to 500kg significant for producers?
The 350kg package limit has been the industry standard for over a decade. Increasing to 500kg extends continuous production run lengths, reduces changeover frequency, and lowers cumulative downtime — all of which improve overall line efficiency without requiring new production infrastructure.
How does the creel maintain fibre quality during high-speed unwinding?
The system uses an electronic tension control mechanism with a closed-loop dancer arm. This continuously adjusts to maintain consistent tension as the bobbin unwinds, preventing fibre breakage and ensuring stable input conditions for downstream carbon fibre processing equipment.
How many VHD creel systems has Cygnet Texkimp installed globally?
The company has more than 70 VHD creel installations in active operation worldwide. These systems collectively handle over 24,000 fibre bobbins, supporting carbon fibre manufacturers across multiple international production hubs.
