1.4 Trimming Edges of Booklets
Figure 30 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 30 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.
