Differences From Single-Needle Machines - Brother 884-T20 Operation Manual

Not all six needles can be used to sew at the same
time. Only one needle is moved to the
embroidering position at a time. According to the
sewing order, the needle bar case is moved to the
left and right so that the needle bar and needle
thread with the required color can be moved to
the embroidering position.
1 Needle at the embroidering position
The needle is positioned over the hole in the
needle plate 2.
When starting the machine, the presser foot is
automatically lowered. The embroidery is sewn
and thread is pulled away from the material when
thread trimming and when changing thread colors
(moving to the different needles to be sewn within
the embroidery). When sewing is finished, the
machine stops. If the pattern uses seven or more
thread colors, the machine will stop when it is
necessary for the thread spools to be changed, and
the corresponding instructions appear on the LCD.
(However, when "Manual Color Sequence" is set
to "ON", the machine does not automatically stop
when a thread spool must be changed. For details,
refer to "Selecting/Managing Thread Colors for
Each Needle Bar (Manual Color Sequence)" on
page 108.)

Differences from single-needle
machines
■ Can sew embroidery patterns using
six or less colors without the need to
replace the thread spools
With single-needle machines, the thread spool must
be changed and the machine must be threaded each
time a different thread color is used. With this
machine, it is not necessary to change the thread
spool or rethread the machine with embroidery
patterns containing six or less colors. If total colors
are less than six colors, and if total color change is
more than seven times, machine will come back to
the needle that the machine is already used and sew
the same color again automatically.
■ Automatic sewing reduces sewing
time
Except to change the thread spools with patterns
containing seven or more colors, once the machine
is started, it continues to operate automatically, from
lowering the presser foot to performing the specified
operations at the starting and end positions in
addition to changing the thread colors. Since the
machine can change threads and finish stitching,
sewing time is reduced.
■ Automatically pulls and holds the
thread tails to the under side of
fabric at the beginning and end of
stitching
Since the machine automatically pulls the upper
thread under the fabric at the beginning of a color,
and pulls the upper thread from the fabric at the
time of thread trimming, you don't need to deal with
the upper thread tail at all.
■ Automatically moves the embroidery
frame to the embroidering position
With a single-needle machine, in most cases, the
embroidery pattern is centered in the frame and the
fabric must be correctly positioned within the
embroidery frame with the center of the desired
embroidering position aligned with the center of the
embroidery frame. However, with 6 needle
embroidery machine, the embroidery frame is
moved to determine the embroidering position,
making it easier to sew the pattern at any place in
the frame. In addition, the embroidering position
can be freely determined manually after the fabric is
hooped and the embroidery frame is attached to the
machine, regardless of how the fabric is positioned
in the embroidery frame.
