N.C. Helical Cut-Off (Double Drive) — Precision Cutting for Corrugated Board Lines

The N.C. Helical Cut-Off (Double Drive) from Hsieh Hsu Machinery is engineered for high-speed corrugated board production, delivering precise sheet cutting, stable operation, and efficient order changes on modern corrugator lines. Installed directly after the N.C. Slitter Scorer, the machine accurately cuts corrugated sheets to the required length before transferring them to the downstream stacking system, keeping the entire production flow continuous and synchronized.

Available in three configurations — NC-C110H, NC-C128H, and NC-C158H — the series offers multiple performance tiers to match different production capacities while maintaining consistent cutting accuracy of ±1.0 mm across all models. Powered by a double AC servo drive system, the machine achieves stable transmission and accurate synchronization even at demanding production speeds, while dual measuring wheels support precise length control and fast order switching, with storage for up to 99 production orders.

Built around a lightweight hollow blade shaft and helical blade structure, the design reduces cutting resistance, improves transmission efficiency, and extends blade service life. Combined with quick blade removal and reverse grinding support, the N.C. Helical Cut-Off is built for manufacturers who need dependable, long-term cutting performance without sacrificing production speed or accuracy.

Inside the DF-12's Heating System: How It Keeps Board Bonding Consistent
Heat consistency is what separates a reliable double backer from one that produces uneven, weak bonds — and it's the core of the DF-12's design. The unit runs 12 to 22 heating plates depending on line configuration, each 150mm in height with ground-polished, chrome-plated surfaces built to release heat evenly across the full board width. Above each plate sit five to six weight rollers, with lift and lower motion handled hydraulically and contact pressure fine-tuned pneumatically — giving operators two separate, adjustable controls rather than one fixed setting for heat transfer and mechanical pressure. In the dedicated heating section, thin-type steel hot plates measuring 120mm (H) × 600mm (W) × 2650mm (L) are arranged across 20 plates, backed by a hydraulic press-shoe unit and three-section steam pressure control. A 15-inch channel steel main frame keeps the whole assembly rigid under continuous heat and pressure. For plants running single or double wall board, that level of independent control is what keeps bonding quality steady from the first sheet to the last.
