Feed Ribbon Drive Roll Friction
Material Replacement
The friction material on the feed ribbon drive
roll must be replaced if the feed ribbons slip in
place when the tension is adjusted correctly.
1. Verify the correct replacement parts are
available, including the friction material,
cement, and filament tape. See the
PARTS LIST .
2. Turn the power OFF at the main discon-
nect switch.
3. Open both end frame doors and locate the
adjusting screws (Figure 7-2, A), which
secure each feed ribbon drive roll bearing
in position. Loosen the locknuts (B), while
holding the screws in position, and back
off each screw the same number of turns
counterclockwise until the feed ribbons
are easily moved by hand.
4. Locate the main drive chain in the right
end frame. Locate the clips that secure
the ends of the drive chain together. Use
a chain puller to relieve tension at the site
of the clips and remove them. Remove
the chain from the feed ribbon drive roll
sprocket.
5. Pull the feed ribbons around their tracks
until all the lacing clips are accessible and
aligned at the front of the unit. Remove
all the connecting pins from the feed rib-
bons. Position the feed ribbons away from
the drive roll.
6. Place a tarp, plastic drop cloth, heavy pa-
per, or another temporary protective cov-
ering over the ironing cylinder, compres-
sion roll, return ribbons, and receiving
shelf.
7. Cut and remove the filament tape located
at each end of the drive roll.
8. Pull or cut off the old feed ribbon drive
roll friction material.
9. Remove old cement from the drive roll
with a scraper, coarse sandpaper, or a steel
brush. Wipe away remaining residue with
a clean cloth.
10. In a strip along the full length of the drive
roll, apply the cement evenly on 1/4 to 1/3
of the cylindrical surface (Figure 7-3).
Smooth it out with a putty knife.
Perform only when the unit is OFF
(with power disconnected) and COOL.
Required Tools
wrench, chain puller, protective
covering, utility knife, marker,
scraper/sand paper/steel brush,
clean cloth, putty knife, filament
tape, masking tape.

roll cover in place.
Figure 7-4: The leading edge of the friction
material must be smooth and tight
against the drive roll in order to
adhere correctly.
