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. 2 1 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, 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. 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 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.
