MBM Corporation iCREASE AIR - Manual (Page 27)

PERFORATING AND SCORING
Your icreaseAIR will come equipped with 1 Perf and 1 Score assembly standard. Up to 4
perf or score assemblies can be used at the same time. Perf and Score assemblies
require the corresponding Perf or Score lower hub assembly in order to function
properly.
PERFORATING
To perforate on your icreaseAIR you will lower the perf blade on the upper assembly
down onto the lower perf assembly. The upper perf assembly will look similar to the
score assembly in design, but will have a black protective guard covering the blade as
illustrated below. The lower perf assembly is made of hardened steel. See the image in
the Perorating and Scoring Section below for detail. From our quality control testing you
will see a line dead center on the lower assembly and this is where you should lower the
blade located on the upper assembly down onto the lower assembly.
Note: The lower perf assembly has a rubber core which is designed to
have some give so that when the perf blade is set against the hardened
steel lower you are not wearing away your perf blade. Because of this
fact; if you set the perf blade anywhere but center on the lower
assembly the lower assembly will “lean” to the right or left and not
give you the ideal perf quality or straightness.
