Lower Seal Band and Bead Disassembly
To remove and replace the lower seal band, PTFE tape, and bead, do the following.
1. Disconnect the VS1620 L-Bar Sealer Tunnel Combo Unit power plug from the
electrical power source.
2. Examine the L-seal area for dirt and debris and for worn parts or torn tape.
3. Temporarily remove the red covers to access the spring compensator assembly
at each end of the seal band.
4. Loosen the spring compensator set screws to unclamp the seal band and free it
at each end.
5. Remove the PTFE tape from the ceramic bead on each side of the seal band.
Discard the PTFE tape, as it cannot be re-used. Place the seal band aside and
pull the ceramic bead out of the channel extrusion. In cross-section, the
arrangement of the seal band, PTFE tape, ceramic bead, and extrusion look
similar to the following illustration and can be disassembled as shown at right.
