How to adjust or replace the Perforation Blade
Inspection
1. The metal guards on either side of the heater rubber are called the wrinkle
preventers. Both wrinkle preventers should be parallel to each other and without
dents. The spring above the depth adjustment screw should push the wrinkle preventer
above the heater rubber. This wrinkle preventer should also slide up and down evenly
without binding.
Blade Removal
NOTE: To make your adjustments easier on narrow packing units, make a mark on the edge of
the anvil assembly block to help orient the new blade during installation. Narrow perforation
blades utilize two of the three set screws. This may also be done on wide packing units to
help with blade alignment.
