YAFEI’s Cutting Paper Cardboard Slotted Knives are designed exclusively for the paper and cardboard processing industry, addressing the need for precise, efficient cutting of pulp, paper, cardboard, and corrugated materials. With a focus on solving common pain points in paper processing—such as frayed edges, material jams, and frequent blade replacement—these knives are built to integrate seamlessly with paper processing equipment, ensuring smooth, continuous production. YAFEI’s expertise in industrial knife manufacturing guarantees that each knife meets the strict quality standards of the paper industry.
The knives feature a precision-ground cutting edge that maintains sharpness even during prolonged contact with paper and cardboard. This reduces the risk of rough edges or torn materials, which often lead to production delays and waste.
Paper and cardboard processing generates fine fibers that can wear down blades over time. YAFEI’s knives are treated with a specialized coating or material blend that resists fiber buildup and wear, extending the blade’s service life and reducing maintenance frequency.
These slotted knives are engineered to fit a range of paper processing machines, including sheeters, slitters, and corrugated cardboard production lines. This compatibility eliminates the need for multiple knife types, simplifying inventory management for manufacturers.
A primary use case is in corrugated cardboard box manufacturing. The knives cut and slot corrugated sheets into box blanks, ensuring the slots are precise for easy folding and assembly—critical for packaging used in shipping, retail displays, and consumer goods.
They are used in sheeting machines to cut large paper rolls into smaller, specified sizes. This application supports industries like printing (for book pages or flyers), office supplies (for notebooks or copy paper), and packaging (for tissue boxes or paper bags).
The knives also work with tissue converting equipment, cutting large tissue rolls into smaller formats for consumer use—such as facial tissues, paper towels, and napkins—ensuring clean cuts that maintain the softness and integrity of the tissue.
Yes. YAFEI’s knives are designed to handle coated and laminated cardboard, which are common in premium packaging. For extra-thick or high-gloss laminated materials, we can adjust the blade’s edge geometry to ensure smooth cutting without damaging the coating.
Replacement frequency depends on usage volume and material type, but YAFEI’s knives typically last 2–3 times longer than generic options. You’ll know it’s time to replace when cutting efficiency drops (e.g., more force is needed) or when edges become uneven. Regular inspection every few weeks is recommended.
Absolutely. YAFEI has experience adapting knife designs to fit older or less common machine models. Provide your machine’s make, model, and any dimensional details, and our team will create a knife that fits perfectly—no need to replace your existing equipment.
No. The knives are designed for easy installation, following the same steps as generic knives for your machine. YAFEI also provides a simple installation guide; if you have questions, our technical team is available to offer support.
