Three models are offered: NDSF-320S at 150 m/min, NDSF-360S at 180 m/min, and NDSF-380S at 200 m/min, with corrugated roller diameters of ϕ320mm, ϕ360mm and ϕ380mm respectively. Effective width is 1400–2200 mm across the range.
It refers to the corrugating roller design that forms the flute without the traditional finger-type pressure fingers, which reduces paper breakage and wear while improving flute formation quality.
The rollers use 48CrMo high-quality alloy steel with HV1200+ surface hardness, finished with carbonized tungsten or hard chromium plating for long-lasting flute accuracy.
A vacuum adsorption system with adjustable air volume holds the cardboard guide steady, keeping the web stable as it moves through the single facer at high speed.
Yes — installation, commissioning and operator training are included with every machine, with after-sales support available.
