Machine Knives for the Paper Industry
Machine knives for the paper industry are precision cutting tools used throughout paper manufacturing, paper converting, cardboard processing, corrugated board production and printing. Depending on the application, different knife designs and cutting geometries are required to achieve clean cuts, high production speeds and consistent cutting quality.
We manufacture machine knives for paper and cardboard processing according to customer drawings, specifications or samples. Depending on the application, our products include cross-cutting knives, shear knives, circular knives, carbide knives, guillotine knives, slitting knives and special machine knives.
Machine Knives for Paper Processing
Paper processing involves a wide range of cutting operations, including longitudinal slitting, cross-cutting, trimming and separating.
Typical machine knives include:
|  |
The appropriate knife geometry depends on the paper grade, thickness, machine speed and cutting process.
Knives for Cardboard and Corrugated Board
Cardboard and corrugated board require precise cutting tools to produce clean edges without damaging the material.
Circular knives and slitting knives are commonly used for longitudinal cutting and trimming in corrugated board and converting applications. Depending on the material and machine, smooth, serrated or specially designed cutting edges can be used.
For demanding applications, carbide or other wear-resistant materials can provide increased service life.
Machine Knives for Printing
Printing and finishing machines require specialized knives for cutting, trimming and processing paper products.
Depending on the machine and application, these may include:
|   |
The knife geometry and material can be adapted to the machine and the required cutting performance.
Punching Knives and Die-Cutting Tools
Punching knives and die-cutting tools are used to produce defined shapes, cut-outs and contours in paper, cardboard and packaging materials.
We manufacture custom punching knives and cutting tools according to drawings or samples, including tools for special contours and individual packaging applications.

Materials for Paper Industry Knives
The choice of material depends on the paper product, machine speed, cutting process and required service life.
Depending on the application, machine knives can be manufactured from:
- Tool steel
- High-alloy tool steel
- High-speed steel (HSS)
- HSS PM
- Carbide
Carbide knives can be particularly suitable for demanding applications where high wear resistance and long service life are required.
Grinding and Resharpening
Precision grinding is essential for maintaining the required cutting-edge geometry and dimensional accuracy. Regular inspection and professional regrinding of machine knives can restore cutting performance and extend tool life.
Depending on the knife design and remaining dimensions, many machine knives can be reground several times. This can reduce replacement costs and help minimize machine downtime.
Custom Machine Knives for the Paper Industry
We manufacture custom machine knives for paper, cardboard and corrugated board processing according to customer drawings, specifications or samples.
Knife dimensions, cutting angles, edge geometries, materials and mounting features can be adapted to the respective machine and application.
If you require machine knives for the paper industry, send us your drawing, sample or technical specifications. We will be happy to advise you on the appropriate knife design and material.
