Knife Holders

Hardened Screw Locking Knife Holders are precision components designed for shear slitting systems, slitter rewinders, rewinders, and slitting machines. They are used to securely mount dished knives on the upper knife shaft and maintain stable cutting pressure against the bottom knife.
Manufactured from high-strength special steel with hardening heat treatment, these knife holders provide enhanced hardness, strength, and wear resistance for continuous industrial slitting applications.
The holder features a screw-locking and snap-ring retaining system for secure knife mounting. Each holder is supplied with a spring and snap ring, while different spring specifications can be selected according to the material being cut and the required cutting pressure.
WINGCHONG KNIFE can also manufacture matching dished knives, bottom knives, counter sleeves, and related slitting components to provide a complete and dimensionally compatible shear slitting solution.

Screw Locking Knife Holders are precision components designed for shear slitting systems, rewinders, slitter rewinders, and slitting machines. They securely mount dished knives on the upper knife shaft and maintain stable knife positioning during operation.
Manufactured from high-strength special steel, the holders receive specialized surface treatment to improve corrosion resistance and wear resistance, supporting reliable performance in continuous slitting applications.
Each holder is supplied with a spring and snap ring. Spring specifications can be selected according to the cutting application, including spring length, wire diameter, and operating tension. The appropriate dished knife geometry and steel grade should also be selected according to the material being processed.
The knife holder and dished knife form the upper section of a shear slitting unit, working against the bottom knife installed on the bottom shaft to achieve precise and stable shear cutting.

Self Locking Knife Holders are precision components designed for shear slitting systems, rewinders, slitter rewinders, slitting machines, and inspection equipment. They are used to securely mount dished knives on the upper knife shaft and maintain stable cutting pressure during operation.
Manufactured from high-strength special steel with a black oxide finish, the holders provide improved corrosion resistance and wear resistance for demanding industrial applications.
The holder features a self-locking ball mechanism that engages automatically when the machine starts, helping maintain secure knife positioning even when the shaft locking mechanism has not been fully engaged. This design provides an additional level of operational safety and reliable knife retention.
Each holder is supplied with a spring and snap ring. Spring specifications can be selected according to the material being processed and the required cutting pressure.
