SEALER ASSEMBLY
SEAL WIRE TENSION SPRINGS
The seal wire tension springs apply the proper
tension to the seal wire while mounted to the
impulse seal bar. They are located inside the bar,
and can only be seen with disassembly.
1. Peel back the Teflon tape on the seal wire.
Inspect the seal wire to ensure it is taught and
lying flat against the phenolic insulating strip.
Also, using a seal wire changing tool, press
each end of the seal wire heater block towards
the center of the machine and ensure there is
resistance. If it appears loose or does not lie
flat against the back strip, the springs are faulty
and need replacement. Note: Sharp Packaging
Systems recommends replacing the tension
springs in pairs to ensure even tensioning.
The seal wire tension springs are adjustment free.
1. Remove the front lexan guard (Figure 3-334).
2. Completely remove the Teflon tape from the
seal wire area (Figure 3-335).
TESTING
