5.6.6 Perforating
To avoid creasing you perforate crossfolds at ”head”. However, perforating at „spine“ should
only be made when perfect binding !
Loosen with hooked wrench 1 nut 2.
Insert perforating knife 3 into knife
holder 4; some knives are slotted 5.
The slitter shaft 6 does not
have to be removed.
Installation of perforating knife 3:
The straight side of the knife must
be adjacent to the grinded side 7 of
the counter knife 8. It must enter with
the obtuse angle 9 first into the sheet.
You avoid jam-up of sheets.
In addition thereto, use stripper 10.
> ATTENTION < When you install
the knife holder 4 make sure that
you turn the nut 2 counter-clockwise.
Wrong installation will cause
opening while the machine
is running!
Use sufficient transport rollers 11
for exact sheet transportation.
Use strippers 12 if lower slitter shaft has
been equipped with perforating knife 3.
> NOTICE < Please bear in mind that
you require different perforating knives
for certain types of papers.
It is absolutely imperative that you follow
the attached List of KnivesTM 32/2.
