Unwinder Assembly
The Unwinder is belt driven from a right angle gear motor. The motor and bearings
are permanently lubricated and require no regular maintenance. Check the belt tension
periodically and adjust if necessary. Check the gear pulley and bearing set screws for
tightness. The electric eye mounted on the guide rod should be set to "see" the border
material before the loop is entirely used up.
General Machine Maintenance
Daily
 Clean machine at the end of every shift
 Clean lint etc. from the Looper/bobbin area on the sewing head
 Remove any threads wrapped around moving parts of the handwheel, puller, and
ruffler.
 Wipe all photo eye lenses with clean, nonabrasive, dry cloth
 Use blow-off hose to get rid of excess lint, thread and other clippings
 Follow manufactures recommendations and guidelines for daily maintenance and
lubricating of the sewing head.
Weekly
 Check all belts for tightness and condition. Adjust or replace as necessary.
 Check oil level in oil pan.
 Put one drop of machine oil on all moving Ruffler parts.
Electric Eye Sensor Adjustment
To adjust the sensor, first remove the clear
plastic cover from the end of the sensor. There are
two adjusting screws under the cover. One is
labeled “GAIN” and is used to set the sensitivity of
the sensor. The other screw is labeled “DO & LO”
and should always be fully clockwise.
With the end of the sensor pointing at the center
of the reflective tape, turn the “GAIN” screw
counter-clockwise until the red LED indicator is off.
Then turn the “GAIN” screw clockwise until the LED
indicator comes on. Then turn the “GAIN” screw one
full turn clockwise. The LED indicator should be
blinking slowly. Cover the eye so that the sensor
cannot see the reflective tape and the LED should go off.
Reflective Tape Maintenance
Use a soft cloth for cleaning.
Do not use chemicals or abrasives to clean it.
Avoid any contact with oils and liquids.
Do not touch the tape with bare fingers.
If tape is dirty or opaque, the eye may not function correctly.
