Custom Circular Knife for Paper Tube Cutting and Textile Slitting

Circular Knife for Paper Tube Cutting and Textile Slitting

Hengye supplies custom round cutting knives for paper converting, textile, packaging and printing applications. The blade is specified by its outside diameter, bore, thickness and cutting-edge profile. Submit these dimensions with the material being cut so the replacement can be matched to the machine.

Match the Blade to the Material

Paper tube cutting and textile slitting impose different demands on an edge. Tube wall construction, fabric structure, material support and blade condition can affect the finished cut. Ragged edges or incomplete separation may also result from incorrect clearance or alignment. Review these conditions alongside the blade specification rather than choosing a knife only by diameter.

Specification Guide

Application Details to Provide

• Paper tubes: tube diameter, wall thickness, construction and cutting method.
• Textiles: fabric type, thickness, layers and required slit width.
• Packaging and printing: substrate, coating or adhesive, line conditions and blade arrangement.

Replacing an Existing Circular Knife

Compare the bore and any mounting features with the shaft or holder. Confirm the bevel direction and working clearance with the machine requirements. Where the existing blade shows chipping, rapid wear or material buildup, include photographs and operating details with the drawing so that steel and surface options can be reviewed.

Frequently Asked Questions

Is this one standard blade size?

No fixed configuration is specified here. Provide outside diameter, bore and thickness to establish the size for quotation and manufacture.

Can the same knife cut both paper tubes and fabric?

Compatibility depends on the machine, material and edge design. These are application categories; they do not establish that one configuration is suitable for both tasks.

How do I request a quotation?

Send a dimensioned drawing, steel grade if known, machine model, material details and quantity. Include required tolerances and surface treatment so the quotation describes a complete blade specification.
