Machine parts and function

1.Reverse Lever

The reverse lever allows you to stitch in reverse. We use reverse to make our stitches secure at the beginning and end of seams.

2.Pattern Selector

The pattern selector lets you determine what kind of stitch you will be making, such as straight stitches or an embroidery stitch or zig-zag.

3.Stitch Length

Stitch length determines the length of the stitch.
Stitch length range 0-4 mm.
Average stitch length 2.5mm.
Typical stitch width range 0-5 mm.
Stitch width is needed for zig-zag stitch

4.Bobbin Winder

The bobbin winder winds the thread from the spool to the bobbin, mechanically.

5. Spool Pin

Spool pin holds the spool of thread.

6. Thread Tension

Thread tension determines the tightness or looseness of the stitch."Righty Tighty, Lefty Lucy" refers to turning the adjustment to the right to tighten the upper thread tension and turning the adjustment to the left to make the upper thread tension looser.

7.Pressure Dial

The pressure dial determines how much pressure the presser foot will have on the fabric.
More pressure may be needed for light weight fabrics, and less pressure for heavy, or thick fabrics.

8. Face Plate

The face plate is a cover that covers all the inner working parts of the sewing machine.

9.Check Spring Holder

The check spring holder is actually hidden in our machines. It works with the thread tension to slow down the amount of the thread going to the needle.

10. Sewing Light

The sewing light helps you to thread the needle and to see your stitching; both day and night.

11. Feed Dogs

Feed dogs are a “teeth-like”part.The basic function of the feed dogs is to move the fabric forward by a distance equal to the stitch length.

12. Throat Plate

The throat plate is a static component which has slots for the feed dogs and a slot for sewing needle for zig-zag stitch. The upper surface of the throat plate is highly polished.

13. Slide Plate

The slide plate is a clear plastic cover that covers the bobbin case to keep dust and dirt out of the moving parts area of the bobbin case.

14.Presser foot

The presserfoot holds the fabric against the feed dogs; so the feed dogs can pull your fabric through the machine.

15. Needle Clamp

The screw that tightens to hold the needle in place, and loosens when you want to change the needle.

16. Presserfoot Lifter

The presserfoot lifter gently lifts the presserfoot up and lowers it against the feed dogs.
Note: the presserfoot must be lowered before you begin to sew; or fabric will not move through the machine!

17. Take-Up-Lever

The take-up-lever pulls the thread back after each stitch, so that the stitches will lay evenly into the fabric.

18. Hand wheel

The main purpose of a hand wheel on a sewing machine is to slowly raise the needle by hand. This gives you control to position fabric under the needle.

20. Power Switch

The power switch turns on the power on the sewing machine and also turns off the power, electrically.

21. Power Socket

The power socket connects the power source to the sewing machine.

22. Foot Pedal

The foot pedal operates the speed of the sewing machine, electrically.

23. Thread Cutter

The thread cutters cut the threads at the end of a row of stitching to disconnect your fabric from the sewing machine.

These are the main parts of a sewing machine.
