JuYou Slitter Rewinder Case Studies and Custom Engineering

Selected JuYou projects showing how standard slitter rewinder platforms are adapted for unusual materials, wider webs, larger rewind diameters, process integration and project-specific production requirements.

Fedrigoni · CLS-A8 Lifecycle Engineering Upgrade

Fedrigoni’s CLS-A8, originally delivered in 2024, later became the focus of a 20-point lifecycle engineering upgrade based on real production feedback. JuYou completed the upgrade program on site in Italy in 2026, including seven major system-level redesigns.

• Machine: CLS-A8
• Original Delivery: 2024
• Upgrade Program: 20 Engineering Items
• Major Redesigns: 7 System-Level Upgrades
• On-Site Implementation: Italy · 2026

The project covered hydraulic and unloading controls, safety architecture and interlocks, knife positioning, rewinding control, diameter measurement and operator workflow. Trial production and final verification followed completion of the multi-system upgrade.

Xianhe · CLS-A8 Specialty Paper Project

Xianhe selected a customized CLS-A8 for 2400 mm specialty-paper production after a previous slitter rewinder did not meet its expectations for production stability.

• Machine: CLS-A8
• Max. Web Width: 2400 mm
• Daily Production Speed: 800–1000 m/min
• Test Speed: 1200 m/min
• Key Configuration: Tungsten carbide knives and carbon-fiber rollers

The project demonstrates material-specific engineering for demanding specialty-paper production, with a focus on production stability and sustained high-speed operation.

OKIL-SATO · Customized SF-850 Laser Perforation Project

JuYou upgraded the SF-850 platform for a 1000 mm rewind diameter and separated the unwind and rewind sections to integrate laser perforation. The two sections are connected through a bottom web path.

• Machine Platform: Customized SF-850 upgrade
• Max. Rewind Diameter: 1000 mm
• Integrated Process: Laser perforation
• Layout: Separated unwind and rewind sections
• Web Path: Bottom web path between sections

The project demonstrates mechanical redesign and process integration around a standard machine platform rather than a simple parameter change.

Final machine configuration and achievable production performance depend on material structure and thickness, web width, slit pattern, roll dimensions, target speed, process integration and factory requirements.
