Using The Twin Needle - Brother SB3150 Operation Manual

Upper Threading

Using the twin needle

With the twin needle, you can sew two parallel lines of the
same stitch with two different threads. Both upper threads
should have the same thickness and quality. Be sure to use the
twin needle, the horizontal spool pin and the appropriate
spool cap.
For details on the stitches that can be sewn with the twin
needle, refer to "Stitch Setting Chart" beginning on page B-45.
Memo
• Traditionally a twin needle is also used for creating
pin tucks. Contact your nearest authorized
Brother dealer to obtain the optional pin tuck foot
for your machine (SA194, F069: XF5832-001).
CAUTION
• Only use the twin needle (2/11 needle, part
code: X59296-121). Use of any other needle
may bend the needle or damage the machine.
• Never use bent needles. Bent needles can
easily break, possibly resulting in injuries.
• The needle threader cannot be used with the
twin needle. If the needle threader is used with
the twin needle, the machine may be
damaged.
Press and install the twin needle.
