Two-Thread Wrapped

Edge Overlock

(Narrow and Wide)

Two-Thread Wrapped Edge Overlock (Narrow)

The Two-Thread Wrapped Edge Overlock provides an elegant fine finish to lightweight fabrics. When using clear threads in conjunction with the Two-Thread stitch, the fabric appears to have an invisible edge. This gives a couture effect and looks beautiful on finer fabrics. The Two-Thread Stitch requires the lower looper thread and one overlock needle thread. The lower looper thread wraps around the fabric’s edge. There are 2 different ways to set up for a Two-Thread Wrapped Edge 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.

 Install the Knife Cover.

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

when sewing. Even though the Upper Looper is not threaded, it needs to be engaged.

1. Push the clutch button to the left and down to engage.

2. Turn handwheel.

 Engage 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 needs to wrap around the fabric’s edge.

1. Raise the white handle on the Spreader to insert the tip into the eye of the Upper Looper.
