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. Figure 32

1.4 Trimming Edges of Booklets
Figure 33 shows the setup of cutting blades and strippers
for trimming edges of booklets or outer edges of circulars
running two or more up.
Cutting blades are attached to blade holder collars so
that the bevel of blades on the upper shaft are directed
toward the strip being trimmed and the bevel of blades on
the lower shaft are directed away from the strip. Blades
mounted in this manner tend to turn trimmed edges down
which helps guide them to the floor. Blade holder collars
are turned out to allow a set of pull-out tires to be placed
close to the cutting blades, preventing the sheet from
buckling or twisting at the point where the cut is being
made.
Use as many additional pull-out tires in the center of the
sheet as necessary.
Set the collar, with blade attached, in the proper position
on the upper shaft. Then move the collar/blade on the lower
shaft so that the flat sides of both blades press snugly
together. Too much space between the blades will cause a
ragged edge on the finished booklet.
Do not attempt to trim less than one-eighth of an
inch. On bulky or heavy sheets a wider trim is necessary.
Figure 33 shows the type strippers used for this work,
mounted on the square bar directly above the shafts. Note
that one is right, the other left, placed accordingly. It may
be necessary to bend the strippers slightly to avoid rubbing
on the cross carrier or stacker. Strippers are adjustable for
up and down movement.
