5.5 Endseal/Crimpers
The endseal consists of two shafts with
heated crimpers� The crimper shafts rotate to
make the seals and cut the film between each
product and to separate them into individual
packages�
Crimpers
WARNING
The wrapper is designed not to
operate when an endseal guard is
open� However; it is recommended
the power be disconnected and
locked out according to OSHA
Standard 1910�147 when making
any of the following adjustments�
Failure to observe this warning may
result in the loss of fingers or a
hand�
WARNING
The crimpers must be adjusted at
operating temperature and they will
be very hot� Do not touch them with
bare hands or a very severe burn
will result�

Pause Position and Speed
The pause position is the point in the
rotation of the endseal where the endseal
shafts are traveling the same speed as
the finseal wheels and sealing material�
If running small or short products, the
material speed is slower than for long
product at the same operating speed� The
pause position is automatically determined
by the wrapper software�
The Pause Offset parameter is used if
the sealing material is either snapping or
bunching up during the sealing phase of
the endseal rotation�
Knife
•
If the material is snapping when the
crimpers are together, enter a negative
value in the Pause Offset parameter�
•
If the material is bunching up when the
Anvil
crimpers are together, enter a positive
value�
Home Position
Home position for the crimper shafts is set
with the flag and proximity sensor located
on the upper shaft� The machine control
module uses the signal from the sensor
to determine endseal crimper position for
proper timing� If the crimpers stop with
the proximity sensor tripped by a flag, the
crimpers will reverse direction and stop
in the open position� If they stop with the
sensor not tripped, the crimpers will rotate
forward and stop in the open position�
