The pneumatic crush cut knife holder features a high-hardness circular blade (made of SKD-11 tool steel) driven vertically by pneumatic pressure. Paired with a surface-hardened anvil roll, it performs precise crush slitting and edge trimming.

Key Features & Advantages:

• Tension-Driven Operation: Neither the circular blade nor the anvil roll requires an external drive; rotation is powered entirely by the web tension during rewinding, ensuring a simplified structure and smooth operation.

• Rapid Width Adjustment: Equipped with “Multech Machinery Corp.” dovetail guide rail, the knife holder can be easily unlocked, repositioned, and secured, significantly reducing downtime during spec changes.
