Scoring; Slitting - Baum FLEXIFOLD Installation & Operation Manual

12.2 Scoring

The Flexifold 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 is to be made. This
applies in all instances when a perforator cannot be used.
Access and installation to the slitter shaft assembly
is the same proceedure as described in the previous section
on slitting.
Attach the scoring blade loosely to the blade holder
for mounting on the slitter shaft. Scoring blades can be
mounted on either the upper or lower slitter shaft. Once
on the shaft, tighten the screws, aligning both the blade
and the collar. This allows free horizontal movement on
the shaft. Scoring blades should be placed so that the fold
will be made with rather than against the scoring, or, in a
continuing direction to the pressure of the crease that has
For a wide, well-rounded score, use the two steel
scoring collars. (See Figure 12.2-1) Sharpness and the depth
of the score can be controlled by regulating the distance the
collars are placed away from the scoring blade.
The scoring collars can also be placed on either side
of the rubber scoring collar. The two collars can be com-
pressed against the rubber collar, causing the rubber to bulge
up for a deeper score. (See Figure 12.2-2)

The Flexifold can be used to cut folded or flat sheets
apart. The general setup for blades and collars is shown in
(Figure 12.3.1). Two or more cuts may be made if duplicate
sets of cutters are used.
Use care in mounting slitter blades to the collars
in order to avoid ragged edges during slitting operations.
Ragged edges 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 caused by tightening
with the wrong type of screw. Always use flat head screws
on the side of the blade and blade holder collar, which are
countersunk.
Before tightening the blade to the collar, slide the
blade with the collar loosely attached on the end of the shaft.
Then tighten securely, thus aligning both the blade and col-
lar, allowing free horizontal movement along the shaft.
Place the blade, mounted on the collar, on the upper
shaft in the proper position where the cut is to be made.
Then move the blade and collar on the lower shaft so that
the two flat edges of the blades are pressed snugly together.
Too much space between the blades will produce a ragged
cut.
Space the rubber pull-out tires to support the sheet.
