Crimper Clearance
The upper shaft can be raised or lowered
to change the clearance between the
upper and lower crimpers� It should be
positioned so it achieves a good seal and
cutoff with the least amount of contact
with the lower crimper� If the crimpers are
too close together, the material will tear;
if they are too far apart, they will not seal
properly� The spacing required between
the crimpers will depend on the thickness
of the sealing material�
Sealing Pressure
The upper endseal shaft is spring loaded
to apply pressure to the sealing material�
These springs also allow the upper
crimper to give slightly if they happen to
close on an obstruction� Spring pressure
has been set at the factory and should not
require adjustment�
Cutoff Knife And Anvil
The upper crimper contains a cutoff
knife and the lower crimper has a backup
plate called an anvil� For the knife to cut
properly, it should extend beyond the
sealing surface only far enough to achieve
a good cutoff� There are two different
styles of cutoff knives; one is adjusted with
screws and the other uses shims�
Product Spacer
The produce spacer is attached to the
bottom crimper shaft� It may consist
of two or three segments depending on
the number of crimpers attached to the
shaft� It should be flush with the sealing
table and discharge belt; its purpose is to
support the product as it moves through
the crimper area�
