2025/05/20Introduction to Twin Knife Cutting Systems
Modern industrial cutting systems rely on advanced twin knife configurations for high-speed, precision operations. The Twin Knife Sheeter and Synchro-Fly Cutter Machine represent state-of-the-art solutions for continuous production lines requiring accurate web cutting.
Core Technology Breakdown
1. Twin Knife Sheeter Mechanism
- Dual-blade configuration: Features two precisely synchronized blades for clean cuts
- Variable speed control: Adjusts to material properties and production requirements
- Continuous operation: Maintains productivity without stopping between cuts
- Material versatility: Handles paper, plastic films, textiles, and composite materials
Key specifications:
- Cutting width range: 500-3000mm
- Maximum speed: 300m/min
- Precision tolerance: ±0.2mm
2. Synchro-Fly Cutter Technology
- Rotating blade system: Maintains tangential cutting speed matching web velocity
- Electronic synchronization: Ensures perfect cut timing through encoder feedback
- Contact-free cutting: Reduces material distortion in delicate applications
- Automated blade adjustment: Compensates for wear without production stoppage
Performance metrics:
- Synchronization accuracy: 0.1mm at full speed
- Blade change time: <3 minutes
- Minimum repeat length: 150mm
