Anatomy of a sewing machine

so interesting, let's Move on

Let us take a look at the uses.
It is very important to know and recognise different parts of sewing machine.
1. Arm: the horizontal upper part of the head which is used for handling upper thread and driving the needle.
2. Back stitch lever: a lever located at the lower right hand side of the machine and has the ability to form the stitches in reverse direction.
3. Bobbin : a small metal spool that holds the lower thread supply.
4. Bobbin case: the metal case that holds the Bobbin. It has the tension spring that controls the pressure on the Bobbin thread.
5. Bobbin winder : it is use for winding the thread on Bobbin and it is located at the right side on the Bobbin thread.

Feed Dog: A small metal device under the presser foot which has teeth which carries the material along as it is stitched. It moves the material forward, by one stitch length, after each stitch has been drawn.
Hand Wheel: Handel is located on the right side of the machine. It is driven by hand or belt in the domestic machine and with the help of belt in the industrial machine. It controls the movement of the needle bar and drives the machine.
Hand Lifter: To lift the presser foot by hand. Head: The upper part of the machine above the stand. It is a complete sewing machine without the bed.
Knee Lifter: To life the presser foot by knee. Needle Bar: A bar at the end of which the needle is attached.
Pan: It is the metal pan under the head that catches oil, lint, broken threads.
Presser Foot: A foot which is used to hold the fabric while stitching. It is detachable and dierent types of foot are available for dierent functions e.g. zipper foot, plastic foot. Presser Foot Lifter: A lever attached to the presser bar to lift up & down the presser foot.
Shuttle: A device that carries the needle thread around the bobbin and forms the lock on the lock stitch.
Stitch Regulator: The length of the stitches is determined by graduation marks on the stitch regulating screw. As you increase the numbers on regulator the number of stitches per inch increases i.e. the size of the stitches decreases and vice-versa.
Tension Regulator: It is a mechanism which controls the tension of upper thread and the quality of stitches. The tension of the thread is adjusted with the help of spring and nut which controls the pressure on the disc. Thread Stand or Spool Pin: It is a metal rod tted either on top or on side of the stand to hold the thread spool.
Thread Take Up Lever: A bar/lever which is located above the tension regulator. It moves up and down. It has a hole through which the thread passes. It feeds thread to the needle and it also tightens loop formed and locks it. Throat Plate: A semicircular disc with a hole to allow needle to pass through it and also has marking in some cases which are used as guidelines while stitching

good morning MA, please I be got the following questions as regards the labelled anatomy of the machine: 1.does the following part mean the same thing? :backstitch lever =reverse stitch lever ,:stitch regulator =stitch selector, tension regulator =tension control ?

secondly I don't seem to locate the following part on the sewing machine by label :1. arm, head, bobbin, bobbing case, pan, handlifter, kneelifter, shuttle, throat plate,

Yes, true. As per others, that weren't there, you can just browse on it. I haven't been able.to upload picture, that is why

Hi am following here

that's OK ma'am,we can move on, and like you said I want to believe those labels that I equalised to mean the same thing from my first questions is YES

Im in....

You are all welcome to Tohimah online fashion school.

Now that we know about the sewing machine anatomy.
Let me chip this in, apart from the basic types of sewing machine, there are still subtypes
1. Straight sewing machine
2. Over locking sewing machine ( this are called weaving machine, used mostly on stretch materials and for both outer and inner finishing.

Now let take a look at some machine problems and their likely causes.
Why must we spend so much money on sewing machine repair when we can do do some little repair by ourselves?
1. Bobbin
Does not wind
A. Make sure the thread is wrapped around the bobbin in proper direction
B. Check to see if bobbin is well placed
C. The rubber ring may be worn out and need replacement.

wind unevenly
A. The thread may not be inserted well
B. The tension spring might need adjustment
C. You may be running too fast.

The needle moves up and down while winding
A. Needle has not been disengaged.

So next time your bobbin experience any of this try and rectify it.
The figure shows how a bobbin look like.

following

Now something may be wrong with fabric.
1. Layers feed unevenly
*presser foot pressure incorrect
*may need to stitch slowly
* the fabric may be very light weight and may need while stitching.

2. Does not feed in straight line
* You may be pulling the fabric
* the needle may be bent.
*the presser foot may be loose or bent

3. Puckers when stitched
* the stitch may not be right for the fabric
* needle may be coarse, bent.
* thread may be too thick
* bobbin thread may be uneven

4. Shows feed mark on the underside
* presser foot pressure may be too heavy.
*the feed may be damaged

5. Fabric is damaged or holes around the stitches
* needle may be blunt or incorrect for the fabric.
* check the nick is the throat plate, foot, or feed.

So anytime we experience this, we are sure to know what's up.

Now let us talk about sewing machine in whole.
A. Motor runs bur handwheel does not run
* thread may be tangled in the bobbin case area.
B. Motor runs, handwheel turns but the needle doesn't not move:
* the needle have been disengaged or non tightened.
* the motor belt may be loose.

C. Motor, hand wheel, and needle moves but fabric does not feed
* make sure the preeser foot is down
*check the stitch length regulator
* the feed dog may be lowered or in down position.

D. Motor, handwheel, needle and fabric moves but no stitch is formed
* there may ne no thread on the needle
*bobbin maybe empty
*needle mat be inserted wrongly.

E. Machine running sluggishly
* machine may need oil or cleaning.
* bobbin winder may be disengaged

F. Run noisily
* need oiling or cleaning
* needle might be bent or not inserted well.
* Bobbin about to be out of thread
* bobbin may not be tight enough.

The picture below shows a presser foot and feed dog respectively.

Now let check out our needle.
1. Unthreads
Machine maybe out of top thread.

2. Breaks
Using incorrect presserfoot
Needle may be bent and hit the presserfoot
Needle may have defects or incorrect being inserted.
Needle may not be right for fabric




Stitches
1. Skip here and there
* needle maybe blunt or bent or wrongly inserted
*pulling of the fabric while sewing.

2. Have loops in between
* bobbin may be winding unevenly
*improper threading
