Solve the challenges of the roll surface while simultaneously improving productivity and maintainability.
【Product Features】 • Excellent non-stick properties to prevent adhesion to roll surfaces The superior non-stick and slippery properties of fluororesin (Teflon) are applied to the rolls. This prevents the adhesion of adhesives, inks, and debris, significantly reducing cleaning efforts and improving productivity. • Wide compatibility from expanders to specially shaped rolls Our expander rolls can be coated, and we can also process special shaped rolls such as metal rolls and crown rolls used by our customers. This enhances the performance of various rolls. • Conductive types available for effective static electricity countermeasures We also offer conductive type tubes that suppress static electricity, which can be a problem in film and paper production lines. This helps prevent dust adhesion to products and reduces the risk of electric shocks.
