Slitter Rewinder Blades: Top and Bottom Knives for Tissue Rewinding Lines
Rewinder blade guide: top knives in 9CrSi to solid carbide, inlaid carbide bottom blades, common specs from φ180 to φ250, OEM production for tissue rewinding lines.
What Rewinder Blades Do
Slitter rewinder blades slit tissue paper into consumer rolls on rewinding machines. Blade quality feeds straight into finished-roll quality and line efficiency: a dull or burred knife leaves fuzzy edges, dust and width variation. Because every rewinder model takes a different geometry, most mills buy these knives as OEM parts rather than catalogue items.
Material Options from Tool Steel to Carbide
• Top (circular) rewinder blades: 9CrSi, SKD-11/D2, M2/SKH-51, and solid tungsten carbide for the longest intervals between changes.
• Bottom (band) blades: 9CrSi, SKD-11, or inlaid carbide — a carbide strip silver-brazed onto a tough tool steel body, solid and seamless.
• Advanced heat treatment plus mirror grinding gives wear resistance without burrs on the cut edge.
Carbide and inlaid-carbide versions cost more up front but repay themselves on high-speed lines through far longer regrind intervals — we help you calculate the payback for your specific paper grade.
Common Sizes and OEM Production
Frequently ordered specifications include φ180×φ70×3, φ190×φ75×3, φ200×φ65×3, φ200×φ90×4, φ250×φ188×15 and φ250×φ140×30 mm, among others. If your machine takes a non-standard size, send a sample or drawing and we manufacture strictly to the design precision.
