Let’s Learn
the parts of
the Sewing Machine
These are our Sewing Machines
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.
The range is from 0 to 4; the longest is 4
0 the shortest 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.
*Students are reminded not to move
this dial; each machine is set for the
number on the tension dial that it
needs.
7. Pressure Dial
The pressure dial determines
how much pressure the
presserfoot 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
that works with the presserfoot to
pull your fabric through the
machine.
12. Throat Plate
The throat plate has stitching guide
lines on it and has a hole for the
needle to pass through to the
bobbin casing
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. Presserfoot
The presserfoot holds the
fabric against the feed dogs;
so the feed dogs can pull
your fabric through the
machine.
15. Needle Clamp
The needle clamp is a black
clamp that tightens to hold the
needle in place.
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. Handwheel
The handwheel raises and lowers the
needle. You must always pull the
handwheel towards yourself to
prevent tangling of the threads.
19. Clutch Knob
The clutch knob is located inside of the
handwheel. It is a safety feature of the
sewing machine that when pulled out,
prevents the needle from jabbing up
and down when winding a bobbin.
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 Cutters
The thread cutters cut the threads at the
end of a row of stitching to disconnect
your fabric from the sewing machine.
