Cygnet Tex-Web Release Blade over Roller Technology
Cygnet Tex-Web have revealed a blade over roller machine designed to deliver exceptionally low coat weights of 10g/m².
The company has transformed traditional blade coating technology to create lightweight, high yield performance composites for a range of markets including medical, marine, aerospace, automotive, work wear and household textiles.
Mark Smith, Commercial Director of Cygnet Tex-Web explains
Blade coating technology is a proven concept in the coating market, but previously its applications were limited because traditional machines were only able to achieve coat weights of 80-100g/m². Our engineering team has revisited the origins of the technology and redeveloped it with a series of critical adjustments that have transformed it into an extremely viable solution that offers substantial, tangible benefits to a range of markets.
The machine features a precision-ground steel roller and blade which are heated before being ground at the temperature of use to eliminate any inaccuracies. An innovative zoned heating system allows accurate temperature control across the width of the steel blade during use and ensures very fine layers of hot-melt coating can be applied to create products with good surface finish and weight uniformity.
Tension controls on the unwind and coating head keep the textile tension constant and ensure accurate, uniform coating, while the angular rotation of the blade can be fine-tuned depending on the application, to deliver exactly the right amount of coating onto the substrate.
