Dished Knives

Double-Bevel Dished Knives are precision-engineered slitter knives for slitter rewinders, web slitting machines, and inline inspection systems. They are designed for clean, consistent shear cutting across a wide range of web materials, including paper, paperboard, aluminum foil, plastic film, adhesive tape, flexible laminates, labels, rubber, and nonwoven fabrics.
The double-bevel edge geometry provides a balanced cutting profile for demanding slitting applications. It helps maintain a stable cutting edge while reducing dust, debris, and uneven material separation during operation.
These dished slitter knives can be supplied for pneumatic knife holders and standard knife holder systems. Knife diameter, bore, thickness, bevel angle, edge geometry, and surface finish can be manufactured to match your machine configuration and cutting requirements.
For applications involving adhesive or laminated materials, mirror-polished slitter knives are available. The smoother surface helps reduce adhesive and material residue accumulating on the knife surface and cutting edge, supporting more consistent slitting performance and easier cleaning.
As a custom slitter knife manufacturer, we can produce knives based on your machine model, technical drawing, existing knife sample, or dimensional specifications.

Single-Bevel Dished Knives are precision-engineered slitter knives designed for inspection tables, slitting machines, and slitter rewinders. They are commonly used for precision shear slitting of labels, flexible laminates, adhesive laminates, nonwoven materials, films, paper, paperboard, aluminum foil, and other web materials.
These single-bevel slitting knives are typically installed in slitting systems equipped with mechanical or pneumatic knife holders. The single-bevel cutting geometry provides a reliable cutting profile for medium- and low-speed slitting applications where dimensional accuracy, stable cutting performance, and material adaptability are important.
For standard configurations, the front face of the knife is precision-ground to provide a sharp and consistent cutting edge, while the back face can be sandblasted for a clean and uniform surface finish. Precision grinding on both faces is also available for applications with specific surface finish or dimensional requirements.
Unlike flat slitter knives commonly used on high-speed converting equipment, single-bevel dished knives are particularly suitable for medium- and low-speed slitting systems. Their dished design and single-bevel edge provide good adaptability to different materials and slitting conditions.
The knife is secured to the knife holder using screws, snap-lock mechanisms, or ball-lock systems to form the upper knife assembly. During operation, the upper assembly works together with the corresponding bottom knife to create a controlled shear-cutting action. As a custom slitter knife manufacturer, we can manufacture single-bevel dished knives, bottom knives, knife holders, and related slitting components according to your machine model, technical drawing, existing sample, dimensions, and application requirements.

Hollow-Bevel Dished Knives are precision-engineered slitter knives designed for slitting machines, rewinders, and inline cutting equipment. They can be used with mechanical knife holders, pneumatic knife holders, and various shear slitting systems.
These hollow-bevel slitter knives are suitable for precision slitting of a wide range of web materials, including paper, paperboard, aluminum foil, plastic films, flexible laminates, adhesive laminates, labels, adhesive tapes, and nonwoven materials.
The hollow-bevel edge geometry is designed to provide a controlled and stable cutting profile for demanding slitting applications. Knife geometry can be optimized according to the material being processed, machine configuration, and required cutting performance.
For adhesive and laminated materials, mirror-polished slitter knives are available. The smoother surface helps reduce adhesive and material residue accumulating on the knife surface and cutting edge, supporting more stable cutting performance and easier cleaning.
In addition to mirror polishing, the knives can be precision-ground through multiple grinding passes to achieve accurate dimensions, consistent edge geometry, and the required knife profile. The grinding process helps maintain dimensional consistency and reliable cutting performance across production batches.
As a custom slitter knife manufacturer, we can manufacture hollow-bevel dished knives according to your machine model, technical drawing, existing knife sample, or dimensional requirements. Custom options include knife diameter, bore, thickness, bevel angle, edge geometry, surface finish, and dimensional tolerances.

Special Dished Knives are custom-engineered slitter knives designed for slitter rewinders, web slitting machines, inspection equipment, and other converting systems. They are developed for applications that require specialized cutting-edge geometries beyond standard single-bevel, double-bevel, or hollow-bevel knife designs.
These special dished slitter knives can be used for precision slitting of paper, paperboard, plastic films, aluminum foil, labels, adhesive tapes, flexible laminates, nonwoven materials, and other web substrates.
For demanding applications, customized serrated edges, tooth profiles, cutting geometries, and edge configurations can be manufactured according to the material and cutting process. The specialized edge design can help improve cutting stability, control material deformation, and reduce material buildup during continuous slitting.
Different surface treatments are also available depending on the application. Precision grinding, mirror polishing, and functional surface coatings can be applied to achieve the required dimensional accuracy, surface finish, wear resistance, or anti-adhesion performance.
