LESSON PROPER: STUDENTS ACTIVITY

Sewing machine is used to join two or more pieces of
materials or to stitch a decoration on a fabric. These
things can be done hand sewing but using the machine Different parts and function of the
for sewing will make the process easier and faster. Machine
1. Point out the different parts of the sewing
machine.

Tell to the students, sewing machine has three major

parts. It is A. Cabinet
B. The Stand or Steel
 C. The head

The purpose of the cabinet is to holds the drawer, the

cover / extension leaf and the center drawer
Kindly read the used of drawer and extension leaf.
1. drawer are used to keep materials for sewing
Drawer are used to keep your materials in one area

2. extension leaf covers the cabinet

Extension leaf covers the cabinet after using or you will
have an additional table or space when sewing.

That is the first major parts..

Second major parts is The Stand or Steel Framework it

has a several parts.
Kindly read..
1. The food rest while sewing on the treadle which

belt.
3. The drive wheel drives the balance wheel
4. The pitman rod connects the treadle to the drive
wheel crank.
5. The drive wheel crank turns the drive wheel
6. The leg supports the stand
Those parts found it in the lower body of the sewing
machine

And the most important part is THE HEAD it is upper

metal part that holds the other mechanisms.
Kindly read the following parts helds by the head. 1. The Arm is used to carry the whole part. It likewise
holds the important mechanisms inside.
It is used to carry the whole part and holds the
important mechanisms inside.
2. The balance wheel it is found at the right of the
bobbin winder. It starts the mechanism in
it coordinate with the drive wheel coordination with the drive wheel

3. Bobbin winder winds the thread in the bobbin that

is used for lower threading. It has three parts the
spindle where the thread is inserter, the rubber
wheel that rubs against the balance wheel and
turns the bobbin winder, and the latch that keeps
Bobbin winder winds the thread in the bobbin that is the bobbin in place while winding
used for lower threading
4. The face plate covers the left end head on
which the needle bar and thread take up lever
are located.

5. The feed dog moves the material as it stitches.

It is found in the middle of the face plate

6. The feed dog regulator is used to adjust the

height of the feed dog.
 7. The Needle clamp holds the fabric against the feed
dog. It is found at the middle of the face plate

8. The Pressure bar holds the pressure foot and

needle.

9. The pressure bar lifter Lowers and raises the

presser foot. It is located on the slot on the face
plate

10. The shuttle holds the bobbin and bobbin case in

place. It is used where the inner threading parts

11. Spool pin holds the spool of thread and it is found

at the top right part of the arm.

12. Stitch regulator is used for reverse stitching, it

controls the length of the stitches and it is found
just below the spool pin.

13. Stop motion screw is used to release or tighten

the movement of the needle bar. It is located at
the center of the balance wheel.

14. Thread Guide guides the upper threading of the

sewing machine

15. Thread take-up lever it controls the flow of needle

thread and is found above the tension regulator

16. Thread plate gives the needles access to the lower

thread through the feed dog. It is found at the
bottom of the presser foot.

17. Upper tension regulates tightness or looseness of

the stitches. It is found at the middle of the face
plate

18. Bobbin is the spool for the lower thread

19. Bobbin case holds the bobbin

2. Differentiate the thread and handling parts

materials of the sewing machine.

There are 2 different parts of the machine for threading

and handling the material.

There is the threading handling parts and Fabric

Handling Parts Thread handling parts
1. Spoon pin

What is for threading handling parts?

 2. Upper thread guide
Spool pin holds the spool of thread and it is found at the
top right part of the arm. 3. Tension assembly
Thread Guide guides the upper threading of the sewing
machine

The tension assembly has little numbers on it and the 4. Thread take up lever
upper thread (needle thread) goes through it. It
controls how tight the thread tension is
5. Lower thread guide
Thread take-up lever it controls the flow of needle
thread and is found above the tension regulator

The thread guide keeps the thread running in the 6. Needle

proper place. If the thread is not threaded correctly,
the tension will be off 7. Needle clamp

The Needle clamp holds the fabric against the feed dog. 8. Bobbin
It is found at the middle of the face plate
Bobbin is the spool for the lower thread 9. Bobbin case

Bobbin case holds the bobbin

Fabric Handling Parts
1. Presser foot
How about the Fabric Handling parts, what are those?

2. Feed dog
The presser foot exerts downward pressure on the
fabric as it is fed under the needle
3. Throat Plate
Their purpose is to pull (feed) the fabric through
the machine, in discrete steps, in-between stitches

A metal plate beneath a sewing machine's needle and 4. Stitch

presser foot. The throat plate has an opening for the
needle to pass through… 5. Feed throw out knob

For lubricating the needle thread of sewing

machines for slitching tabrics

3. Discuss and demonstrate the proper use of

sewing machine

Here’s How to operate and care the sewing Machine

1. Turn the balance wheel toward you to raise the
needle to the highest point.
In Upper threading process. 2. Raise the presser foot lifter.
Before you thread the machine you have to
3. Place spool of thread on spool pin. Hold end of the
thread.
 4. Pull thread down toward tension assembly.

5. Pass thread under and around tension disc. See

Then place your spool of thread on the spool pin that it falls between the two disks.
and begin to thread the machine. 6. Bring thread upward so that it is caught by the
hook and thread guide
7. Pull thread up and behind next thread guide.
8. Pass thread through the thread take up lever
9. Bring thread down and through thread guide
10. Pass end of thread through eye of the needle.
Make sure it goes in the proper direction for your
machine. Pull at least 7 cm of thread through the
needle.

The bobbin and bobbin case

What parts carry the lower threading?

The bobbin and bobbin case carry the lower a. Stop the movement of the needle by loosening
threads and stop motion screw.

What steps in threading the bobbin?

b. Lift the presser foot and thread take up lever when

winding a bobbin

c. When the bobbin is wound, remove it from the

bobbin winder
d. Place the bobbin in the bobbin case
e. When the bobbin is in place, you will need to pass
the end of the bobbin threading through

f. Pass end of bobbin thread through opening the

case.

Insert the bobbin in the bobbin case

Properly bobbin wound
 That is how to carry the lower threading.

Of course, sewing machine needs cleaning and oiling. It

needs oil regularly, especially when it is making noise
while you are running it. Be sure to use the proper oil. 1. oil the treadle.
2. Oil the bobbin winder
Which part of the sewing machine should put 3. Oil the upper part of the machine
oil?

Generalization:

The selection use and care of sewing equipment and

materials influences the quality of workmanship and
the satisfaction derived from sewing.

The proper care and use of equipment and materials

extends their life and efficiency of the device

Knowledge of the parts of the sewing machine, the

function of each sewing machine part, and how to
operate the sewing machine makes sewing easier,
more enjoyable and more efficient.
