High-speed Nonwoven Slitting Machine

The unwind section is engineered to handle large-diameter parent rolls up to Φ3500 mm, a capacity that supports single-load continuous operation exceeding eight hours at rated speeds, reducing the frequency of roll changes and associated downtime. The three-zone closed-loop tension system with independent floating-roll sensors at each station provides feedback-based tension regulation across the full speed range, with programmable tapered tension winding adjusting roll hardness progressively as diameter increases. The quick-change blade system enables width configuration adjustments without full shaft removal, with pneumatic blade holders delivering consistent cutting pressure across the web. The cutter shaft is precision-balanced and surface-hardened, with axial runout maintained at ≤3μm. The 40mm heavy-gauge steel frame undergoes 60-day natural aging to relieve welding-induced internal stresses, combined with integrated vibration-damping base mounts. The control platform incorporates a 7-inch touchscreen with 50-recipe storage, fault diagnostics, and energy consumption monitoring. The integrated fiber collection system captures cutting debris in real time.

This machine is typically specified by high-volume nonwoven converters serving hygiene product manufacturers, medical supply companies, and export-oriented converting operations. The large unwind and rewind diameters combined with 1600 m/min speed capability are suited for continuous, multi-shift production schedules. Primary applications include high-volume slitting of SMS and spunlace nonwovens for diaper topsheets, acquisition distribution layers, and medical barrier fabrics. The meltblown processing capability makes it relevant for filtration media production. The machine is also deployed in the production of heavy-duty industrial nonwovens for automotive insulation, construction membranes, and industrial filtration applications. Biodegradable nonwoven materials including PLA and corn-fiber substrates for shopping bags, table covers, and agricultural ground covers can be processed with the machine's adjustable low-tension settings. The equipment is selected by facilities that require consistent quality output across extended production campaigns with scheduled maintenance intervals.
