1.4 Trimming Edges of Booklets
Cutting blades and strippers for trimming edges of
booklets or outer edges of circulars running two or more up,
are attached to blade holder collars so that the bevel of the
blades on the upper shaft are directed toward the strip being
trimmed and the bevel of the 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.
The strippers used for this work are mounted on the
square bar directly above the shafts. Note that one is right,
and the other left. Place them 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.
1.5 Trimming a Strip from Center of Sheet
A quarter inch trim out of the center of a sheet may be
made. Two or more trims may be made as long as duplicate
sets of cutters and strippers are used and this setup adhered
to.
To remove the trim, place the appropriate center
stripper between two of the cutting blades attached to a
collar.
Attaching blades to collars is very important and should
be done with care. The bevel of the cutting blades on the top
shaft should always be directed toward the strip to be
trimmed.
Before the cutting blades are tightened to the blade
holder collars, slide both the collar and attached blade on
the end of the shaft so that they are accurately aligned. Place
cutting blades on the upper shaft to the proper position
where the cut is to be made. Then place collars on the lower
shaft so that the flat sides are pressed snugly together. Too
much space between the blades will give a ragged edge.
Always examine blades for dullness and nicks which will
cause the same condition.
When blades are in the proper position, mount the
stripper. Be sure the stripper does not touch the sides of the
cutting blades.
With this setup, the trimmed out section automatically
goes between the blades on the lower shaft, where it is
carried down and around and guided to the floor by the
stripper wire.
1.6 Blade Installation
WARNING!!!
EXTREME CARE MUST BE TAKEN IN THE
REMOVAL AND INSTALLATION OF ALL
SLITTING, PERFORATING, AND SCORING
BLADES. EXCESSIVE FORCE AND/OR
MISUSE CAN CAUSE PERSONAL INJURY,
BREAKAGE, EQUIPMENT AND MACHINE
DAMAGE
All blade attachments are performed in the same
manner. The locking collar of the blade holder is
removed using the provided spanner wrench.
The blade to be changed is moved far enough along
the slitter shaft to permit the blade to be twisted open
and slipped from the shaft via the slit in the blade.
Install the new blade in the reverse order. Twist the
blade so that the slit opens. Slip the blade onto the
slitter shaft, and replace and tighten the locking collar
with the furnished spanner wrench.
