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 piece borders). When making continental foundations, the good side will face the
operator.
