2. Overlockers (video)


Overlockers are ideal for finishes and for sewing stretchy materials. The stitching is flexible.

The use of overlockers differs from sewing machines

  • Usually operated with 3 or 4 threads, which are thinner (120) or crêpe threads.
  • Needle threads (1–2) run on top of the machine.
  • Looper threads (2) run inside the machine.
  • You cannot backstitch on an overlocker, sew past the edge of the fabric to finish off. The remaining tail must be separately finished to stop the seam from unravelling.
  • Some overlockers have a cutting blade.
  • The pressure foot can be lifted using the small pedal, and you can move forward by using the larger pedal.
Adjusting the machine settings

  • The basic settings (thread tension) are good for most materials.
  • Overlockers are challenging to adjust, do not do it alone.
  • The workshop master can help if adjustment is needed, for example, to create a very stretchy stitch.

Lifting the pressure foot and cutting the thread

  • A separate small pedal, no automatic cutting of thread.

Cutting blade

  • All material on the right side of the blade is cut off.
  • Do not sew over needles, the blade will become blunt and unusable.

Needles

  • See device-specific set of needles.
  • 2 needles, you can use only one needle for a three-thread overlock.
