Servo-Driven Rotary Die Cutter
The Servo-Driven Rotary Die Cutter is engineered for high-speed, tight-tolerance web converting and die-cutting. Utilizing independent multi-axis servo motor control, this machine synchronizes cylinder rotation directly with web feed speed. It eliminates mechanical gear backlash, reduces setup waste, and maintains a registration accuracy of ±0.03 mm at continuous speeds up to 150 m/min. Built for continuous industrial operation in packaging, label converting, and technical textile manufacturing lines.

Key Features
Multi-Axis Servo Synchronization: Each rotary cylinder is driven by an independent servo motor, removing gear trains to eliminate backlash and mechanical wear.
Closed-Loop Tension Regulation: Integrated ultrasonic edge sensors and magnetic particle brakes/clutches maintain constant web tension from full to empty rolls, preventing substrate elongation.
Quick-Change Magnetic Cylinder System: Tool-free cylinder extraction allows operators to swap magnetic dies in under 10 minutes, minimizing line downtime between job changes.
Automatic Registration Control (ARC): High-speed optical mark sensors dynamically adjust phase angles in real time to correct print-to-cut drift instantly.
Heavy-Duty Cast Iron Frame: 60 mm stress-relieved Meehanite cast iron side walls absorb high linear cutting loads and suppress vibration at peak speeds.
Applications
Self-Adhesive Labels: Blank and pre-printed paper, BOPP, PE, and PET label converting with kiss-cutting and matrix stripping.
Flexible Packaging: Easy-open tear notches, sachets, and pouches made from laminated barrier films.
Medical & Hygiene Disposables: Multi-layer breathable films, transdermal patches, wound care dressings, and feminine hygiene components.
Electronics & Industrial Tapes: Die-cutting of double-sided foam tapes, EMI shielding gaskets, graphite sheets, and diffuser films.
Configuration & Customization
Unwind Modules:
Available with automatic flying splice unwinding for continuous 24/7 non-stop production.
Matrix Removal:
Equipped with driven waste rewind turrets featuring constant tension control to prevent matrix breakage at high speeds.
In-Line Processing Integration:
Can be combined with flexographic printing units, cold foil stamping stations, slitting modules, and sheet delivery conveyors.
Vision Inspection Systems:
Optional 100% CCD camera inspection integration for real-time defect detection and automatic reject gating.
Manufacturing & Quality Control
Machined on rigid CNC floor-boring mills, side frames are finish-machined in a single clamping operation to guarantee parallel alignment within 0.01 mm. Rotary cylinders are forged from alloy tool steel (DIN 1.2379 / D2 equivalent), vacuum heat-treated to HRC 58-62, and precision-ground to TIR < 0.005 mm.
Every machine undergoes a strict 72-hour factory acceptance test (FAT) running actual customer sample substrates at rated speeds (verified on 50 μm plastic film and 2 mm high-density EVA foam). Dynamic balancing reports, material mill test certificates (MTC), and electrical schematic packages are supplied with every unit. CE and ISO 9001 compliance standards are applied strictly across all manufacturing steps.
Installation & Technical Support
Detailed foundation drawings, pneumatic requirements, and electrical layout schematics provided 4 weeks prior to shipment.
Factory-certified service engineers available for on-site mechanical installation, web path calibration, and operator training.
Secure VPN router integrated into the PLC control panel for real-time remote troubleshooting and software updates by application engineers.
Critical wear components (servo drives, proximity sensors, pneumatic cylinders) stocked locally for dispatch within 24 hours.
