SCORING/SLITTING/PERFORATING
Your new folder is capable of many different applications
that compliment the folding performance and provide for
greater productivity.
The folder is equipped with slitter shafts that are quickly
set up for the required operation. These shafts accommodate
the mounting of the standard and optional accessories
available that perform scoring, slitting and perforating
functions.
1.0 Slitter Shaft Accessories Removal
To remove slitter shafts, remove knob (Figure 29-1).
Insert knob into the center of the slitter housing (29-2) and
remove the housing, using the knob. Add or remove the
parts needed for the current job using the wrench (Figure
30) provided with the machine. See the following pages for
more information on perfing, scoring, and slitting. Reinstall
slitter housing and knob before starting the machine.

1.1 Scoring
The folder can be used to score a sheet and deliver it
flat, or to score a sheet after a fold or folds have been
made.
To ensure accuracy in making right angle folds,
always score the sheet where the fold or folds are to be
made. This applies in all instances when a perforator
cannot be used.
Various weights of stock with few or numerous folds
require a different type of score. Some jobs require a
narrow, sharp score, usually when the folds are few, and a
fuller, more rounded score when the job becomes bulky.
The scoring blade is normally mounted on the upper
slitter shaft. Scoring is accomplished by running the
score blade in one of the two grooves of the lower score
collar. The sharpness and depth of score is controlled by
which groove the score is made in. The wider groove
produces a wider, more rounded score; while the narrower
groove produces a sharper, tighter score.
The pullout tires are used to control and support the
sheet as it passes through the slitter shafts.

1.2 Perforating
The folder may be used for perforating either the heads
of booklets (to allow the air to escape in making right-angle
folds) or to slot perforate sheets delivered flat, using blades
and strippers best adapted for a particular job.
All perforating blades are mounted on the upper shaft
and run in a grooved steel collar on the lower shaft with the
flat side of the blade just touching a side of the groove.
When doing book work, perforator blades should be
mounted with the bevel side of the blade toward the follow-
ing bank of fold rollers, the direction the signature will be
travelling. (See Figure 31). When mounted in this manner
there is slightly less tendency for the sections of the signa-
ture to come apart and less tendency for one section to pull
out of line with another. This is particularly true when
folding in an up fold plate.
A stripper must be used with each perforation. The
forked spring steel stripper requires a little more care in
mounting and is most often used when perforating only, as
there is less tendency for the perforated sheet to break apart.
