Brother PR-620 Differences with single-needle machines, Machine Structure and Features

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.

Differences with 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 6 colors, and if

total color change is more than 7 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

1Needle 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, and the embroidery is sewn while performing pulling thread from the materials at the thread trimming and while changing thread colors (moving the needle to be sewn within the embroidering). 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.

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 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 this

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 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.
