| 21 built-in sewing patterns plus original patterns |
Program selection is as easy as pressing a button. 90 separate programs can be stored in memory. Furthermore, you can add up to 9 original patterns with programming software for electronic pattern sewer (optional product).
|
Simple and easy-to-use operation panel
There is a program memo pocket provided on the back of the panel. This lets the operator keep necessary information such as a parameter table, program notes and an error code table on hand for easy reference. The operator can select panel position whichever above or below the work table. |
 |
Ideal for sewing vertical buttonholes
A wider operating area is available when the machine head is positioned horizontally on the work table. |
|
|
| Easy operation |
| The presser foot lifter is driven by a pulse motor, so that the height can be adjusted as desired (standard function) for when the pedal is at the neutral position and when it is depressed forward (two stages) and backward. This makes insertion and removal of the material easier and reduces working fatigue. |
| The presser foot rises only by the height necessary, so that the time needed for it to rise and drop can be shortened. |
|
 |
No need for adjustments such as replacing cutter cams when changing number of stitches
The cutter vertical movements is driven by a double position solenoid. If not using a cutter, the cutter operation can be deactivated at the press of a key. The cutter operates without slowing down the sewing machine, and the cutter response time is also fast, so that cycle time is reduced and productivity is increased. |
 |
Purl stitch / Whip stitch
The upper thread tension is controlled by a solenoid, so that setting between purl stitches and whip stitches can be done simply by selecting them on the operation panel. Fine adjustments to the upper thread tension are made using a thread tension nut. The same method that operators have become used to allows the optimum thread tension to be easily obtained. |
 |
Quiet operating environment
Adoption of a clutchless mechanism ensures quieter operating environment and increased durability. |
|
Easy threading
The needle bar can be moved to the right as a matter of course, and this makes threading much easier. |
Accurate home position detection
The home position sensor incorporates a non-optical proximity sensor, so the sensor is not subject to operating errors from oil or dust, and cleaning oil and dust from the sensor are also unnecessary. |
|
Thread trimming speed can be set
The lower thread trimming mechanism operates in conjunction with the presser foot lifter mechanism, and is driven by a pulse motor. As a result, the thread trimmer driving speed can also be changed at the operation panel. |
|
Stable zigzag seams even at high speed
A new needle zigzag mechanism (patent pending) reduces the effect of vibration from upper shaft rotation on the needle bar, so that stable and accurate needle zigzagging is obtained even at high speeds. When sewing speed has been changed, a knife is not used to trim the thread. The cutter space does not change, further making sure that the finish is attractive. |
 |
Adjustment of zigzag width balance is possible
The left and right stitch width ratio for buttonholes can be set on the operation panel. |

Wide sewing range
The thread take-up, rotary hook and thread path mechanisms provide ideal balance, so that attractive buttonholes can be sewn in a variety of different materials under a variety conditions.
Accurate cutter operation
The cutter vertical movements is driven by a double position solenoid, so that the material is cut more acurately.
Clean finish with no upper thread trailing length
Attractive finishes are obtained with no upper thread trailing at the sewing end. This ensures a stable and consistent high-quality sewing finish is always obtained.
Better stitches at the sewing start
Adoption of a bobbin presser prevents the bobbin from spinning free when the lower thread is trimmed. This makes lower thread feeding more stable and produces better stitches at the sewing start. And the lower thread holding device holds the lower thread at the sewing start to ensure that the thread end is sewn into the seam properly. |
|
Under lay
Up to four pattern can be combined and sewn together. |
 |
Rectangle
- Effective for preventing material from stretching.
- If the seam is hidden and the width seems small, sew 2-3 underlays to make the material look more voluminous.
- Because the material can be move slightly up to five times, the seam flexibility is maintained and the button hole strength can also be increased.
|
|
 |
Saw shape
- This is useful for preventing dimples from forming during bar tacking.
- It is also effective for strengthening the buttonholes to stop the seam from unravelling, which can often happen with materials with coarse weaves.
|
 |
Sew together
- If the cutter has operated before the seam has been formed, the hole made by the cutter is sewn up beforehand.
- The pile of fluffy fabric is pressed down before sewing, so that the buttonhole finish looks more attractive.

Selectable cutter operation
The operation of the cutter can be set to one of four timings (front knife, center knife, rear knife and front + center knife). When the front knife setting is used, the rough edges are hemmed by the buttonhole stitches after cutting, thus providing a more attractive finish. When ¡ÈFeeding when cutter operating¡É is set, only the feed mechanism operates after sewing and the cutter moves to the specified position, so that the button hole can be cut right up to the front backtacking. |
 |
|
|
Two-cycle sewing
When set to two-cycle cross sewing, the zigzag stitches sewn during the first and second cycles do not overlap with each other, so that the sewing pitch appears finer and the finish looks even more attractive.
Prevents dimples at the rear tack
Selectable rear tack vector shape prevents dimples at the rear tack section when not using an underlay.
Zigzag sewing pitch
The zigzag pitch setting range has been made even finer. You can now select intermediate pitches which were previously impossible. |
