Roll slitting and rewinding machine

Proposed solution

A heavy-duty, high-speed slitting and rewinding system engineered for jumbo rolls of paper, coated paper, paperboard, kraft paper, aluminium foil and comparable web materials. The machine combines shaftless hydraulic unwinding, automatic tension control, servo-driven rewinding and circular-knife slitting in one robust production platform.

Scope of Supply

One new KFQ-1600 high-speed slitting and rewinding machine.

Heavy-duty shaftless hydraulic unwinding stand.

Two 3-inch pneumatic rewinding shafts.

Ten circular slitting knives as standard.

Automatic web-guiding and ultrasonic edge-correction system.

Waste-edge extraction fan and automatic edge discharge arrangement.

PLC-based control system with touch-screen operator interface.

CE-compliant machine configuration and standard operating documentation.

Application

The KFQ-1600 is suitable for slitting and rewinding a wide range of jumbo-roll materials, including aluminium foil, coated paper, paperboard, kraft paper and other compatible substrates. Its centre-surface rewinding system and automatic tension regulation are designed to support stable production across different material types and roll diameters.

Main Performance Features

Synchronous control using three servo motors for coordinated web handling and rewinding.

Automatic constant-tension structure with centre-surface rewinding.

Frequency-inverter speed regulation for smooth acceleration and stable running.

Automatic metre counting, alarms and essential production-monitoring functions.

A/B pneumatic rewinding shaft arrangement for efficient loading and unloading.

Ultrasonic edge sensing and automatic web correction.

Circular-knife slitting with automatic waste-edge discharge.

Hydraulic shaftless unwinding stand for heavy jumbo rolls.

Robust 60 mm steel wall plates for improved structural rigidity.
