Three-Thread Overlock

(Narrow, Wide, and Wide

with Decorative Threads)

Three-Thread Overlock (Narrow)

The Three-Thread Overlock Stitch is the most commonly used stitch because of

its versatility. It provides a wonderful professional seam finish to woven fabrics. It is

beneficial in preventing loosely woven fabrics from unraveling. In addition, the

Three-Thread Overlock Stitch offers unlimited decorative capabilities. It is

recommended for finishing seams but not reinforcing the seam. Use the conventional

sewing machine’s straight stitch to reinforce the seam. The stitch uses one overedge

needles and both the upper looper and lower looper. There are 2 different ways to set

up for a Three-Thread Overlock stitch. For a more narrow stitch (4.0) select the Right

Overedge needle; for a wider stitch (6.0) the Left Overedge needle is used.

Engage Upper Looper. Engaging the Upper Looper causes the looper move when

Disengage Spreader. The Upper Looper has a hole for the thread on the top of the

looper. If the stitch requires that the looper be engaged but not threaded, then the

Spreader is used. The Spreader simply plugs-in (or closes) the looper’s hole. The

Spreader is disengaged when the Upper Looper is engaged/operative and threaded.

The Spreader is used with a stitch that requires only one looper thread. With

the help of the Spreader, the single looper thread wraps around the fabric’s

edge.

1. Lower the white handle on the Spreader to open the eye of the Upper

Looper.

Thread Upper Looper with regular overlock thread.

1. Raise the Presser Foot to release the

tension disks. Thread the Lower

Looper as illustrated 1-9.

2. Pass thread from back to the

front through the thread

guide.

it slips under the guide. Then pull the thread along the right side of the

button as illustrated.

4. While holding the thread, firmly pull the thread between the tension disks.

5. Turn the handwheel toward you until the lower looper extends 5-10mm

(approximately ½”) from the needle plate edge.

6. Thread the looper area of the machine following the green color coded

thread guides 4-9.
