J3B-75C / J3B-48C Pneumatic knifeholder

Suitable for high performance processes

• Precise and repeatable micrometer knife depth engagement makes top knife bottom knife overlap setting easy and accurate.
• Precise and simple side load cutting pressure adjustment. Pressure is displayed on a gauge and adjusted with a simple valve.
• Prolonged blade durability and excellent cut quality

     J3B is used on Helios systems where the top and bottom knives are moved as a pair

(for example automatic systems, STJ side trim, Fast Man, etc ....)

What sets this knife holder apart is the ability to adjust the cutting pressure pneumatically, meaning all the knife holders mounted on the machine can work at the same side load pressure.

Excessive side load pressure setting errors are reduced as the operator can physically see the load being applied to the bottom knife.

This results in a greater top and bottom knife life on the machine necessitating fewer knife changes and therefore improving machine efficiency.

The J3B knife holder is robustly constructed for long life durability and high speed operation.

The J3B is particularly suited for arduous applications where maximum performance is required.
