to cut multiple thickness of paper or simi lar materials. It is comprised of:
5-23.1 Knife Assembly.
Performs the actual cutting. It is comprised of:
a. Main drive clutch. Controlled by the hydraulic system. Couples the main drive
gear to drive motor and drives the knife. Brakes stop the main drive gear when
hydraulic pressure is released.
b. Main drive gear.
Converts high rpm from the clutch to low rpm at the
eccentric.
c. Eccentric.
Converts rotary motion from the main drive gear into linear
motion.
d. Connecting rod. Linkage between the eccentric and the knife carrier. Pulls
the knife downward at a 45 angle to perform the cut. It contains a shear bolt that
is designed to break if the knife carrier cannot complete its cut due to jamming.
e . Knife carrier. A cast-iron structure which supports the knife. It rides in
two machined grooves which give it a shearing motion when pulled down by the
connecting rod.
f. Knife. A beveled-edge, tempered-steel plate that is mounted to the knife
carrier and performs the actual cut.
