Wave Stitch
Converting from Normal Serging to Wave
The Wave Stitch provides a decorative "wavy" edging on fabric. (This is not to be confused with "Lettuce
Edge" on page 33). The upper looper thread and the lower looper thread gradually appear every 25 stitches
to create a stitch that looks like a "Wave". When using different color specialty threads (see pages 76 & 77)
for the upper or lower loopers, the Wave stitch creates an attractive stitch for edging.
When combining decorative threads for the Wave stitch, please sew test on a sample of the fabric you will
be sewing on before applying the Wave stitch.
For best results, heavier decorative threads should be limited to the upper or lower looper at one time. Not
both upper looper and lower looper at the same time. Wooly nylon in the corresponding looper and maxilock
thread in the right needle will make a striking combination with the heavy decorative thread.
1. Move the Wave Selector lever from "O" to "W".
2. Cut the threads from the thread cones and remove from the thread paths.
3. Lock the machine for threading the loopers. (See page 19).
4. Place the right needle thread cone on the OVERLOCK NEEDLE 2 spool pin.
5. Slip the right needle thread into the telescopic thread guide directly above the thread. Follow the left
overlock needle threading path down to the right overlock needle.
6. Thread the O-2 needle using the needle threader. (See page 24.)
7. Place the upper looper thread cone on the upper looper spool pin.
8. Slip the upper looper thread into the telescopic thread guide directly above the thread. Follow the top
threading path for the right overlock needle thread, down the front threading path, to the left of the
chrome thread guide, and directly to the "U" jet air threading port for the upper looper. Set the Looper
Threader Selector on "U". Thread the upper looper. (See page 20.)
9. Place the needle thread and upper looper thread under the presser foot and to the back.
10. Place the lower looper thread cone on the lower looper spool pin.
11. Slip the lower looper thread into the telescopic thread guide directly above the thread, then slip the
thread into the chain looper telescopic thread guide to avoid the thread getting tangled while sewing.
Take the thread through the standard lower looper threading path
to
the "L" jet air threading
port for the
lower looper. Set the Looper Threader Selector on "L". Thread the lower looper. (See page 20.)
12. Unlock the machine.
13. Set Stitch Selector for Wave Stitch or Rolled Wave Stitch. (See page 41 to 43 for correct settings.)
14. Set Stitch Length and Stitch Width following the illustration on page 41, 42 or 43.
