Stepper Control Box
There is a stepping motor box located under the
table. The Ruffler box has three thumbwheels on the
front which are set to synchronize the Ruffler to the
sewing head. The number is proportional to the stitch
length and is not affected by sewing speed. The 10-turn
potentiometer is used to set the speed of the Ruffler
during the feed in to pleat and feed out to make the
next ruffle. It is set to maximum and is locked in place
by a small locking lever. Unlock to adjust.
Note: The on/off switch only switches one
line and does not make the box safe to work on.
Always disconnect the main power cord before
servicing the control box.
Efka Control Box
The sewing machine is powered by the Efka
motor controller located under the table. It has its own
on/off switch which should be left on at all times. It also
has some small buttons and LED's on the front to
indicate the enabled functions. The only LED that
should be on is the second to last from the bottom
which sets the control to stop the machine needle
down at neutral treadle and needle up after full heal
back. The functions can be changed upon power up
or after a full heal back. The control box has been
preprogrammed to operate with the Ruffler. If the
box were replaced, the new box would need to be
programmed according to the included parameter
list in order to function properly. Notice that the
sewing head does not stop at normal needle up
(lockstitch heads) position after full heal back, but
stops at needle top dead center to allow more room
for loading thicker material (the head actually turns
in reverse for a moment).
Basic Machine Operation
Loading the Gusset Roll and Unwinder
Remove the small disc from the roll holding rod. Load the border roll onto the rod
so the good side is up for making one piece borders or down for making foundation caps.
The border must pass through the guide rod, between the feed rollers, under the Loop
Eye, and over the guide roller above the ruffler. Replace the small disc onto the spindle
with just enough pressure on the roll to hold it in place but allow it to rotate. Heal back on
the treadle
to activate the Unwinder and create a loop of gusset as you continue to load the machine.
Feed the border down to the folder with the good side toward the sewing head (for one
