so that the fold is made with, rather than against the
scoring, or, in a continuing direction to the pressure or
crease that has been applied by the scoring blade.
32-A) Score directly on the wide, soft rubber tire with a
collar mounted at either side. By this method, depth of the
scoring can be increased by compressing the collars to
expand the tire.
32-B) For a wide, well-rounded score, the two steel
collars alone are sometimes used. Sharpness and depth of
the score can be controlled by regulating the distance the
collars are placed away from the scoring blade.

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 perforate sheets delivered flat, using blades
and strippers best adapted for a particular job.
All perforating blades are mounted on the upper shaft
and run in a grooved steel collar on the lower shaft with the
flat side of the blade just touching a side of the groove.
When doing book work, perforator blades should be
mounted with the bevel side of the blade toward the follow-
ing bank of fold rollers. (See Figure 34). When mounted in
this manner there is slightly less tendency for the sections of
the signature to come apart and less tendency for one
section to pull out of line with another. This is particularly
true when folding in an up fold plate.
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.
