Perforating on your Baumfolder
The purpose in using a perforator is to allow air to
escape. With certain types of folds such as wrap
around folds, it pockets air and it is not allowed to
escape. This causes ripples or “crows feet”. This
is not acceptable in quality printing. The cuts in
the perforation allow the air to escape. Normally
the perforation is in a trimmed area.
You can use commercial perforators for coupons or tear off to return for value, but it leaves a
push out on the back of the paper. This is acceptable in most Mailings.
The perforator holds the sheet and would wrap around the shaft. The stripper is mounted on
the bar above the slitter shaft and between the top and bottom slitter shaft to strip the sheet
off the perforator blade. You can mount it beside the perforator blade and it is less likely to
get caught in the perforator blade.
When fastening the blade to the collar, do not tighten the screws until you slide the collar and
blade onto the slitter shaft. Tighten the two screws and then locate the perforator where you
want it. Mount the perforator collar under the blade with the blade in the wide groove of the
perforator collar. Move the sharp edge of the perforator blade against the edge of the groove
in the perforator collar and tighten the brass point set screw to lock it in place. Then install
the stripper assembly. If you visualize the bevel of the perforator blade as an arrow, the
arrow should point to the next fold section. The parts and the part numbers are listed below.
