5.1 Stitch Type

With this machine different stitch formations can be set. These stitches are achieved by different
configurations of needles and mechanical settings.

Overlock Stitch

The 3- and 4-Thread Overlock are considered standard overlock stitches for sewing two layers of fabric
together, for finishing cut edges, e. g. facings, hem edges and seam allowances that are ironed apart.
The 2-Thread Overlock is ideal for finishing a fabric edge.
4-Thread Overlock
The 4-Thread Overlock is the most durable stitch thanks to the safety seam. The left and right overlock
needle thread as well as the upper and lower looper thread are required for this stitch. The overlock needle
threads form two parallel stitch rows, which on the front side look like step stitch rows of a sewing machine.
On the wrong side, the overlock needle threads form «dots» to catch the under looper thread when the
fabric is pierced, whereby the right overlock needle thread also serves as a safety seam.
3-Thread Overlock
The 3-Thread Overlock is usually stretchable than the 4-Thread. Therefore it is ideal for seams on knitted
fabrics (LN wide) or fine fabrics (RN narrow).
2-Thread Overlock
The 2-Thread Overlock is formed with an overlock needle thread (LN wide or RN narrow) and the under
looper thread. The lower looper thread is guided to the right side of the fabric by means of the hooked-in
upper looper converter. This overlock stitch is only suitable for edge finishing.
