360° Blade Guard Cartridge - Pneumatic
Class I
– 718312
The guard protects the blade during handling and non-operation when air is not supplied to the
knifeholder. The guard is to prevent bodily injury during handling or if the product is dropped.
The guard consists of the guard flap, a pneumatic cylinder, a wedge cam, cylinder mount and a return
spring that keeps the guard closed when air is not supplied to the cylinder. When air is applied, the
cylinder retracts and the flap exposes the blade for the slitting operation. The flap and knifeholder
downstroke operation is staged so that the flap never interferes with the anvil ring.
