Announces Release of ST2 – Innovative Servo Tensioner for High-Speed Winding
Salt Lake City, Utah, USA, July 7, 2020 – Engineering Technology Corporation, a global expert in filament winding and composite solutions previously known as “Entec,” has developed a new compact servo tensioning creel for high-speed wet, dry, and towpreg winding. The primary goal of development was to provide an accurate tensioner with a low number of contact points and the capability to maintain accuracy at high payout speeds.
The system has been thoroughly tested with the most challenging fibers, such as pitch carbon fiber, alumina fiber, and others ranging from 1,000 to 50,000 filaments.
The guide rollers’ unique configuration keeps fuzz to a minimum and reduces stringer wrap-ups, which are an inherent issue with some fiber types. The ST2 can accommodate up to sixteen 9-inch (22.9 cm) diameter bobbins in an 82” X 72” X 40” (208.3cm X 182.8cm X 101.6cm) footprint. The system can be customized based on production-specific requirements.
“The ST2 high-speed tensioner was designed to meet and exceed the ever-increasing demands of modern fiber winding. The new tensioning creel is particularly important for the company’s portfolio because it was developed to handle the high winding speeds achieved with the new CXG filament winder geared to the high production of COPVs. ST2 went through a rigorous development period, and it was amazing to see how stable the tensioning system performed even at fast payout speeds,” said B Jay Larson, General Manager.
