Uniformly spreads wrinkles in sheet processing, improving productivity and reducing costs — with consistent performance across the full roll width.
The PN Expander Roll is a straight roll expander designed to eliminate wrinkles in sheet materials, preventing production problems and ensuring stable operation.
An adjustable mechanism with inclined units expands and contracts the rubber tubes mounted on the roll surface. This allows precise control of spreading according to the sheet conditions, without web deviation or excessive stretching in the center, contributing to high-quality output.
Key Features
Excellent product characteristics
• No lateral deviation like curved expanders.
• Prevents excessive tension in the center and sagging at the roll ends.
• Flat roll design allows installation even with a larger wrap angle.
• Prevents sheet biting during single-shaft slitting by spreading the web.
Easy maintenance
• Only consumable parts need replacement, which can be done easily on-site, ensuring long-term, reliable operation.
