8.2 Scoring
The 714 Friction 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.
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
been applied by the scoring blade.
Figure 8.2-1
For a wide, well-rounded score, use the two steel
scoring collars. (See Figure 8.2-1) 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
compressed against the rubber collar, causing the rubber
to bulge up for a deeper score. (See Figure 8.2-2)

8.3 Slitting
NOTE:
Slitting accessories are optional on your 714
Friction and can be ordered from your BAUMFOLDER
Parts Department.
The 714 Friction can be used to cut folded or flat
sheets apart. The general setup for blades and collars is
shown in (Figure 8.3.1). Two or more cuts may be made if
duplicate sets of cutters are used.
Figure 8.3.-1
TOP SHAFT
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.
