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
Removal of the slitter shafts is accomplished via noncor-
rosive linchpins (20). Add or remove the parts needed for the
current job using the wrench provided with the machine. See
the following pages for more information on perfing, scoring,
and slitting. Reinstall slitter by reversing the above proce-
dure.
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 two rounded scoring collars. The sharpness
and depth of score is controlled by the groove between
these collars. 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 perforated sheets delivered flat, using blades
and strippers best adapted for a particular job.
Perforating blades are normally mounted on the upper
shaft and ran in a grooved steel collar on the lower shaft with
the flat side of the blade just touching a side of the groove.
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.
1.3 Slitting (Cutting) Sheets
Folders may be used to cut folded or flat sheets apart.
Two or more cuts may be made if duplicate sets of slitters
are used.
Be careful when mounting slitter blades to collars in
order to avoid ragged edges which can be caused by two
conditions:
1) Nicks or burrs on the collars or blades. Remove
carefully by filing or using a fine piece of emery cloth.
2) Incorrect mounting of blades. Too much gap between
slitting blades will result in a ragged cut
Space the pull out tires evenly to support the sheet.
