Back-Tack Device
The back-tack device allows you to easily
insert the overlock chain-off threads into the
seam at the beginning fabric edge. The device
may be used when sewing these stitches:
Safety 4 Thread, Stretch Knit, Overlock 3, 3
Thread Wide, Overcast 2, Overcast 2 Wide
and Stretch Wrapped.
Raise the presser foot and gently remove the
overlock chain-off threads from the instant
rolled hem device (stitch width finger). Pull the
stitches to the back and then around to the
front. Secure the threads into the back-tack
device.
Place the fabric directly in front of the
needle(s). It may be necessary to hand trim
the first 3 cm (1") along the seam line. Lower
the presser foot and sew. The overlock chain-
off threads are automatically inserted into the
seam on the fabric underside.
NOTE: The back-tack device cannot be used
for the 5 Thread, Blanket, Chainstitch, Cover
Hems or Rolled/Narrow Hems.
