Non-Woven & Hygiene Machine Knives Manufacturer

Cutting and sealing blades for mask machines, diaper lines, non-woven converting and ultrasonic cutting stations. Hardened stainless and tool steel grades that hold an edge against abrasive synthetic fibre without rusting in a wash-down room.

Non-Woven & Hygiene Knives — non-woven cutting blades, factory direct

Key features

  • Ultrasonic horn-matching blades and cold-cut knives
  • 440C stainless: no rust in humid, wash-down mask rooms
  • Edge held against abrasive PP / PET / nylon fibre
  • Wave, straight and serrated edges for sealing and cutting

Fitting your machine, and buying a replacement

Blades and welding rolls for mask machines, hygiene production lines and non-woven converting equipment. Ultrasonic welding tooth rolls are made to the pattern drawing; the tooth height and pitch decide the bond strength, so we do not change them without your approval.

Materials used for this blade

Frequently asked questions

An ultrasonic blade vibrates at 20–40 kHz and welds the edge as it cuts, giving a sealed, fray-free finish — used where the edge must not unravel. A cold-cut blade simply shears the material and is used where a welded edge is not required. They are not interchangeable: send us the machine type and we will confirm which you need.
Synthetic fibre — especially PP and glass-filled material — is abrasive. A blade cutting meltblown at line speed dulls faster than one cutting paper. Two things help: a harder substrate (SKD-11 at HRC 60–62 rather than 420 stainless) and a correct edge angle. Too sharp an angle rolls over immediately; too blunt an angle drags the fibre rather than cutting it.
Yes. Send a photo of the blade with its dimensions, or one used blade. These blades are small and the geometry varies between machine builders, so we always confirm the drawing before production.
Yes, 5 pieces. Non-woven lines change products frequently, so we deliberately keep the minimum low and repeat orders fast for an established profile.
Yes, to your pattern drawing. Send the drawing with tooth height, pitch and pattern; we quote the roll and the matching blade together because they have to run as a pair.
Check the gap between horn and roll first, then the pattern alignment. A new roll that is a few hundredths different in diameter changes the gap, and the weld drops off before anything else does.

Not sure which blade fits?

Send a photo of the blade you use now with a ruler next to it. We will tell you the grade and the edge angle.
