Main corrugated roller: ¢ 320mm (according to the different type), pressure roller ¢ 324mm, pre-heated roller ¢ 320mm.
★ Using negative pressure design, low heat loss, so that the core paper can be evenly pressed and attached to the surface of the corrugated roller, so that the corrugated better molding, because the pressure is uniform, the corrugated top can be better, evenly coated with glue, so that the single corrugated joint is better.
★ Corrugated roller adopts 48 CrMo high-quality alloy steel, after quality adjustment, medium frequency quenching, the surface after grinding and chrome plating treatment, the surface hardness is strong.
★ Corrugated roller, pressure roller and other high stability airbag control system, and has the pressure control buffer effect.
