A concise, SEO-friendly overview of our servo belt haul-off machine and the integrated servo puller cutter (fly-knife cutter), built for stable traction, precise length cutting, and efficient inline automation. Optimized with keywords like servo belt haul-off machine, servo puller cutter, fly-knife cutter, closed-loop servo control, and extrusion haul-off.
Servo Puller Cutter Combination (Traction + Fly-Knife Cutting)
Overview: Integrated Servo Puller Cutter for Inline Precision
Our servo puller cutter combines a dual-belt haul-off with a rotary fly-knife cutting system. With closed-loop servo control, it achieves accurate, clean, and efficient cut-on-the-fly performance for PVC/PE pipes, soft tubes, and profiles—ideal for space-saving extrusion lines.
Key Features: Traction Section (Servo Belt Haul-Off)
- Power: 380V, 50Hz three-phase supply for industrial stability.
- Traction frame: 600 mm length; center height 1000 mm (adjustable) for easy line matching.
- Upper frame adjustment: Handwheel adjustment for quick pressure and height changes.
- Traction belts: 80 mm-width red belts, high-friction and wear-resistant for smooth haul-off.
- Motors: 2× 0.75 kW INVT/INVT-class servo motors for synchronized traction.
- Traction wheels: Precision aluminum wheels, lightweight and balanced to reduce vibration.
- Gearboxes: 2× helical (planetary) precision reducers, high transmission accuracy for consistent speed.
- Top plate: 10 mm rigid table for stability; square-tube welded frame for durability.
- Electrical system: Delixi electricals, Schneider contactors, Siemens HMI for reliable control.
- Auxiliary: Upright PTFE guide roller at the inlet protects surface; traction speed independently controlled.
- Integrated panel: Puller and cutter share the same control panel; set traction speed and cutting length directly.
Key Features: Fly-Knife Cutting Section
- Servo motor: 1.8 kW INVT-class servo for dynamic rotary cutting.
- Cutting method: Rotary fly-knife for fast, clean, and low-burr cuts.
- Clamping: Extended collet at both ends for firmer, more precise clamping and better cut quality.
- Center height: 1000 mm ± 50 mm for easy alignment with the extrusion line.
- Electricals: Delixi electricals, Schneider contactors ensure long service life.
- Length setting: Cutting length fully adjustable; supports batch counting.
- Control system: INVT PLC with Siemens display; unified HMI logic across puller and cutter.
Benefits: Why Choose the Servo Puller Cutter
- Accurate length cutting: Closed-loop servo synchronization enables on-the-fly cuts with consistent length.
- Compact footprint: Integrated puller + cutter reduces wiring, layout, and commissioning time.
- Cleaner edges: Fly-knife cutting with precise clamping delivers low-burr, dust-reduced results.
- Easy operation: Handwheel adjustments, recipe-based HMI, and integrated counters for productivity.
- Reliable components: Schneider, Siemens, Delixi, and precision reducers for long-term stability.

User Feedback and Market Performance
What Customers Say
- Consistent length accuracy and smoother surfaces at higher speeds.
- Reduced changeover time with handwheel adjustments and recipe-based settings.
- Lower maintenance thanks to precision reducers, quality electrics, and rigid frames.
Typical Results
- Scrap reduction through stable haul-off and precise fly-knife cutting.
- Faster commissioning using integrated controls (INVT PLC + Siemens HMI).
- Improved uptime and operator friendliness on multi-model extrusion lines.
Why It Stands Out
Innovation and Competitiveness
- Closed-loop servo control across haul-off and cutter for synchronized, on-the-fly cutting.
- Precision gearboxes and high-friction belts minimize slip and variation.
- Trusted brands (Schneider, Siemens, Delixi) ensure long-term reliability and global support.
