6.4.12 Crimpers - Set Knife and Anvil
Using a dull knife will caue a poor end seal
and put excessive stress on the drive train
of the wrapper. Always replace the knife
and anvil at the same time.
Install the Anvil
1. Examine the slot in the anvil to make
sure there is no dirt or debris in the
slot.
2. Install the anvil into the lower crimper,
making sure it is fully seated.
3. Check to make sure the top of the anvil
is even with the bottom of the crimper
serration. It if is too low, install a full-
length shim under the anvil until it is
even with the bottom of the crimper
serration.
4. Tighten the set screws (1).
Top of anvil reaches bottom
of crimper serration
NOTE: Use the fewest number of shims to
achieve the proper height (for example:
use one .010" shim instead of five .002"
shims).

Install the Knife (adjustable knife style)
The adjusting screw style knives use a
tapered adjusting screw, which acts like
a wedge to extend the cutting edge of the
knife. The knife should extend beyond the
sealing surface only far enough to achieve
a good cutoff.
1. Loosen the setscrews (1) and the
adjusting capscrews (2) to remove the
old knife.
2. Install a new knife. Make sure it is
fully seated against the adjusting
screws, then tighten the setscrews
and the adjusting screws.
3. Turn on the heat to the crimpers
and allow them to come up to
temperature.
4. To determine where adjustments
are required, jog the machine to the
crimper open position.
5. Open the guards and place a single
layer of film between the crimpers.
6. Close the operator guard and jog the
machine to make a cut impression.
7. Open the operators guard and
evaluate where adjustments are
required.
• To move the knife out, loosen
the setscrews and tighten the
adjusting capscrews.
• To move the knife in, loosen the
adjusting capscrews and the set
screws and push the knife in.
