NOTE:
Spiral-wind the friction
material at a 45° angle. To ensure
this, the material edges must be
aligned with no gaps.
11. Spiral wind the new cover over the roll
without cement
to make sure there is
enough material to cover the roll. Put it on
in the same spiral pattern as before.
12. Use a caulk gun to apply several beads of
cement across the length of the roll.
13. Use a serrated putty knife or other rough-
edged tool to spread the cement evenly
over the entire roll (Figure 7-37).
14. Starting either side of the machine:
• Spiral-wind two or three turns of the
material onto the roll and secure it with
masking tape so the material does not
unwind during installation.
• Carefully continue to spiral-wind the
cover onto the roll, making sure it goes
on smoothly without any gaps.
• This procedure is easier with two peo-
ple. One person turns the drive roll by
hand while a second person holds the
roll of material and guides the material
onto the drive roll, pressing it firmly
into place.
• Continue working down the length of
the roll.
• After the roll is covered, wrap the other
end of the roll with masking tape.
15. Use a hammer to lightly tap the friction
material at each end to break it off and
create an even edge or use a utility knife
to trim it.
16. Use a nail to pierce the friction material
and expose the holes for the end screws.
17. Remove the masking tape and then re-
install the end screws (Figure 7-36).
18. Remove the temporary protective covering
and clean up the area.
19. Refasten the return ribbons. Stagger the
positions of the lacing clips to give the
flatwork a smooth flow.
20. Remove the wire/string/guide tape holding
the return ribbon guide assembly in the
high position.
21. Reinstall the drive chain on the return
ribbon drive roll sprocket and adjust its
tension; refer to Drive Chain Tension
Adjustment on page 7-23 .
22. Close and secure both endframe doors.
WARNING
Never operate the unit unless
all safety covers are in place
and all safety equipment is
working correctly.
23. Reinstall the front receiving shelf.
24. Allow the cement to harden for 5 to 6
hours before operating the unit.
25. After the cement hardens, verify the return
ribbon tension spring is functioning cor-
rectly; refer to Return Ribbon Tension
Spring Replacement on page 7-37
