General Machine Adjustments
Air Pressure
Set all air supply pressure regulators (Right to left):
Main Pressure:
70 PSI
This is the main regulator which limits maximum pressure to the solenoid valves and
cylinders.
Puller Pressure:
30 PSI
This is the Down pressure for the puller roller. Too much pressure may cause the
puller roller to stall. Too little pressure may cause the roller to not feed properly.
Ruffle Blade Pressure 10 PSI
This is the Down pressure for the ruffling blade. If it is set too low the ruffles will not
form properly due to slippage of the blade against the material. If it is set too high it will
press the stripper blade down to touch the bed plate of the machine and pinch the panel
causing difficulty in turning the corners.
Foot Sew Pressure:
15 PSI
This in the Down pressure on the presser foot while sewing straight (Not ruffling). It is
set for best feeding of the feed dog. The pressure while ruffling is set by the knob on top
of the sewing head. It is set to be very light so the ruffling blade can feed under the foot
and form the ruffles properly.
Sewing Head
See Manufactures manuals for normal adjustments and parts. The presser foot spring
pressure should be set very light so that the ruffling blade can feed under the foot while
ruffling. The Efka motor should be set for stopping needle down at neutral treadle to help
hold the ruffle in place while turning the corners. The auxiliary foot pressure cylinder
should be set to provide added foot pressure while sewing straight.
Ruffler Drive
Set the Ruffler blade position left to right. The slot in the Ruffler blade should align
with the sewing needle. Loosen the 4 clamp screws and adjust ruffler blade left or right as
needed.
Set the Ruffler blade IN position so that the front edge of the blade is even with the
needle when the ruffler drive is positioned at the IN sensor. To position the drive at the
sensor, press the manual ruffle button once and quickly tap the treadle or sew pedal. The
Ruffler should position itself at the IN sensor. Adjust the sensor position in its slot, press
the manual ruffle button to reset the ruffler and repeat the cycle to test the setting.
Set the Ruffler blade OUT position by turning the adjusting knob on the front cover of
the ruffler drive. This controls how big each ruffle will be. After making an adjustment,
always reset the ruffler by pressing the manual ruffle button twice.
The swing-out stripper blade protects the panel from the ruffler blade while ruffling so
that the panel does not get pleated by the blade. It should be positioned as close to the
