Bottom Feed Slitting Rewinding Machine for Heavy Paper Rolls

Engineered for High-Speed, High-Tension Paper Converting Operations

In modern paper mills and converting plants, inefficient slitting and unstable tension control often lead to material waste, roll defects, and costly downtime.

This bottom feed slitting rewinding machine is specifically designed to handle jumbo paper rolls with high precision, stable tension, and continuous high-speed operation, making it ideal for kraft paper, packaging paper, and industrial base paper processing.

Why Choose a Bottom Feed Slitting Rewinder?

Unlike traditional top-feed systems, the bottom feed structure allows:

• Easier loading of heavy jumbo rolls (Ø2000 mm)

• Improved operator safety

• More stable web alignment and tension control

• Reduced downtime during roll changeovers

This design is especially suitable for paper mills and large-scale converting lines handling high-volume production.

Key Advantages That Improve Your Production Efficiency

1. High-Speed Slitting up to 600 m/min

Maintain consistent output with a designed speed of 650 m/min, ensuring your production line keeps up with demand.

2. Precision Tension Control (Up to 1200 N/m)

The integrated braking system ensures:

• Stable web tension

• Reduced wrinkles and breaks

• Improved finished roll quality

Perfect for high-density and high-grammage paper (70–250 g/m²).

3. Heavy-Duty Jumbo Roll Handling

• Parent roll width: up to 2760 mm

• Parent roll diameter: up to Ø2000 mm

Built for paper mill-grade operations, handling large rolls without compromising accuracy.

4. Pneumatic Knife Slitting System

Equipped with 4 sets of pneumatic top knives, delivering:

• Clean, precise cuts

• Minimal edge damage

• Consistent roll width control

5. Automatic Rewinding & Roll Handling

• Automatic trimmed roll push system

• Lowering cradle for safe unloading

• Consistent roll tightness and diameter control

Reduces labor intensity while improving operational efficiency.

6. Stable and Intelligent Drive System

• 45 kW main motor

• Frequency converter for precise speed regulation

Ensures smooth acceleration, deceleration, and long-term reliability.

Typical Applications
