YAFEI’s Paper Tubes Circular Sitting Knives are specialized tools for the paper tube manufacturing industry, engineered to deliver precise, uniform cutting of paper tubes— a critical component in packaging, textiles, and industrial applications. Unlike generic paper knives, these circular knives are designed to handle the unique challenges of cutting cylindrical paper tubes, such as ensuring even pressure around the tube and avoiding deformation. With YAFEI’s expertise in paper industry tools, these knives ensure consistent quality, reduced waste, and compatibility with various paper tube production lines.
The circular shape of the knives ensures that pressure is distributed evenly around the paper tube during cutting. This eliminates uneven edges or crushed tubes, a common issue with flat knives when cutting cylindrical materials.
Paper tubes (especially thick or dense ones) exert unique stress on blades. YAFEI uses materials that resist chipping and dulling, even when cutting tubes used for industrial cores (such as textile rolls or adhesive tape cores).
Paper tubes come in various diameters and lengths, so YAFEI offers both standard and custom knife sizes. This ensures the knife fits your tube dimensions perfectly, whether you’re producing small packaging tubes or large industrial cores.
The primary use is in paper tube production facilities, where the knives cut large paper tube blanks into specific lengths. This is essential for making products like cosmetic packaging tubes, shipping cores for textiles, and cylindrical containers for small parts.
They are used to cut paper cores—hollow tubes used to wind materials like printing paper, film, or foil. Precise cutting ensures the cores fit seamlessly with winding equipment, preventing material slippage during production.
For small-batch or custom paper tube production (such as luxury packaging or artisanal crafts), these knives offer the flexibility to cut tubes into unique lengths or shapes, supporting creative and specialized manufacturing needs.
Yes. The knives are designed to handle varying wall thicknesses, from thin packaging tubes to thick industrial cores. For extra-thick tubes, YAFEI can recommend a specialized blade material to maintain cutting performance.
Regular circular paper knives are designed for flat paper sheets, not cylindrical tubes. YAFEI’s Paper Tubes Circular Sitting Knives have a unique edge angle and balance that ensures even cutting around the tube, preventing damage. They also have a more robust construction to handle the pressure of cutting curved surfaces.
In most cases, no. The knives are designed to fit standard paper tube machine knife holders. If your machine has unique specifications, YAFEI can customize the knife’s mounting features to ensure compatibility.
First, check if the knife is properly aligned—misalignment is the most common cause of crushing. If alignment is correct, inspect the knife edge for dullness; a dull blade requires more force, which can crush tubes. Sharpening or replacing the blade should resolve the issue.
