Needle
Needle number
11, 14, 16, 18, 20
The arm
The horizontal upper part of the head which has the upper thread handling and needle movement.
Back stitch lever
A lever at the bottom right of the machine and its basic function is to make the stitches in the opposite direction.
bed
The bottom of the machine stands ie under which there are mechanisms to handle the lower thread including shuttle and feed.
Bobbin
A small metal spool that holds the supply of the lower thread.
Bobbin case
The metal case that holds the bobbin. It has a tension spring that controls the pressure on the bobbin thread.
Bobbin winder
It is a simple mechanism for mounting the thread on the bobbin and is located on the right hand side near the wheel.
Feed dog
Under the presser foot is a small metal device with teeth that attach to the material as well as stitches. This advances the material, followed by a stitch length, followed by pulling each stitch.
Hand wheel
Handel is located on the right side of the machine. It is operated by hand or belt in domestic achine and with the help of belt in industrial machine. It controls the speed of the needle bar and drives the machine.
Hand lifter
Hand lift
Head
Top of the machine above the stand. It is a complete sewing machine without a bed.
Knee lifter
To give life to the presser foot from the knee.
Needle band
A bandage at the end of which there is a needle.
The pan
It is a metal pan under the head that holds oil, lint, broken thread.
presser foot
A leg that is used to hold the fabric while sewing. It is separable and different types of feet are available for different types e.g. Zipper legs, plastic legs.
Presser foot lifter
The lever is attached to the lever to lift it up and down with the presser foot.
Shuttle
A device that moves the thread of the needle around the bobbin and creates a lock on the lock stitch.
Sewing regulator
The length of the stitches is determined by the graduation mark on the stitch regulation screw. As you increase the number on the regulator, the number of stitches per inch increases i.e. the size of the stitches decreases and vice versa.
Stress regulator
It is a mechanism that controls the tension of the upper thread and the quality of the sutures. The tension of the thread is adjusted with the help of a spring and nut which control the pressure on the disc.
Thread stand or spool pin
It is a metal rod that is fitted on the top or side of the stand to hold the spool of thread.
Thread take up lever
A bar / lever that is located above the stress regulator. It is up and down. It has a hole through which the thread passes. This feeds the thread to the needle and it also tightens the loop formation and locks it.
Neck plate
A semicircular disk with needle through which the needle is allowed to pass through and in some cases also marking which is used as a guideline when sewing.
Bobbin
1. There is no wind:
Make sure the thread is wrapped around the bobbin in the proper direction.
Check to see if the bobbin is properly placed in the winder.
The rubber ring can be worn and needs to be replaced.
2. Unevenly:
Threads cannot be inserted into guides.
You must be running the machine very fast.
Tension spring adjustment may be required.
3. The needle moves up and down during winding:
The needle is not displaced
The cloth
1. Layers feed unevenly:
Presser foot pressure wrong
May need to be stitched slowly
The fabric may use very light weight tissue paper while sewing
2. Does not eat in a straight line:
Pressing leg may be loose or bent
Pressure of pressure can be wrong
The needle may be bent
There may be a defect in the machine feed
You can move or pull the fabric forward
3. Fritters on cooking:
Many clothes are cooked when sewn into a single layer
The stitch length may not be correct with respect to the type of fabric
If the clothes are sheer or light weight, regulating presser foot tension may be required.
The thread may be too thick
Needles may be thick
Bobbin thread may be uneven
Stitch tension may be unbalanced
Feed dog can be worn
4. The feed mark on the underside shows:
Pressure of the presser foot can be very heavy. You may need to apply tissue paper between the fabric and the feed
The feed may be damaged or set too high
5. If the fabric is damaged or holes around the stitches:
Needles for clothes may be blunt or very coarse or incorrect.
Check for nicks in throat plate, foot or feed
machine
Motor not running:
1. The cord is not plugged.
2. Power off.
3. The knee or leg accelerator may be jammed or improperly connected to the power source.
The motor runs but the hand wheel does not turn:
A thread or lint may get caught or tangled in the bobbin case area.
The motor runs, the hand wheel turns, but the needle does not move:
1. The needle is displaced for bobbin winding and cannot be tightened back to the stitch position
2. If the needle is tightened, but still does not move, the motor belt is slipping because it is loose or has corroded.
The motor, hand wheel and needle move but do not feed clothing:
1. Make sure the pressure is down
2. Check the stitch length regulator
3. Pressure regulator may be under minimal / mild pressure. If the fabric is heavy, more pressure may be necessary.
Clothes for feeding
4. The feed dog may be in the down or "down" position
The motor, hand wheel, needle and clothes move but no stitching is made:
1. The needle may remove thread.
2. Needles can be threaded in the wrong direction.
3. The needle may be inserted backwards or pushed upward in a clamp.
4. The needle may be the wrong length for the machine.
5. Machine can be threaded incorrectly
6. The bobbin can be empty
7. The bobbin and / or case may be inserted incorrectly
8. Machine time may stop
Moves slowly:
1. Bobbin winder can still be fitted
2. Knee or foot control may be improperly deployed
3. Machine may be required for oiling and / or cleaning
Noise
1. The machine may need oiling and / or cleaning
2. The needle can be tilted in front of the foot or throat plate
3. The bobbin and / or case may not be tight enough
4. The bobbin may be almost out of thread.
Will not stitch in reverse:
1. If the machine is too old, it may not have this capability
2. If this is a recent model, check the stitch control. If set to "Stretch Stitch" or "Buttonhole",
Needle
Another:
1. Insufficient threads could be pulled through the needle before the suture began
2. Machine can be out of top thread
Brake:
1. You must be using the wrong presser foot
2. There may be loose or improper fastening. "Presser foot or neck plate
3. The needle may be bent and the pressure may hit the foot and / or throat plate
4. The needle may be inserted incorrectly
5. Needles may also be fine for sewing clothes and for work
6. You must have worked very hard on the fabric while sewing
7. Check the machine settings.
8. Needle may be defective
Stitches
Uneven lengths are:
1. You can push or pull the fabric too much
2. Pressure on presser foot can be either too light or too heavy for clothes
3. The feed can be lint or other clogged between the teeth of the dog
The ends between them:
1. If the loops are large, the machine is improperly threaded
2. If the loops are small then they become unbalanced
3. The bobbin may be unevenly wound
4. There may not be enough pressure to hold the stem of the fabric during the formation of the stitch
Drop here and there:
1. The needle may be blunt or bent
2. The needle may be inserted backwards or it may not be completely in the clamp
3. There may be insufficient pressure on the presser foot
4. Throat plate may be incorrect
5. You can stitch at an uneven speed
6. While sewing, you can dress
The thread
Needle thread breaks:
1. This is usually due to inserting the needle backward or backward.
2. The spit can be caught in the spool notch or it can be wrapped around the spindle
3. A thread guide may have a rough or bulging spot
4. The needle may be blunt
5. Clamp may not have needle all the way
6. The needle can be very fine for threads, causing it to flare — often the case with a silk buttonhole twist.
Bobbin thread breaks:
1. The bobbin case cannot be threaded properly and / or the case is not inserted properly
2. The bobbin can be very full
3. Clean the bobbin completely so that the thread does not stick.
4. Bobbin tension can be very tight
The bobbin thread cannot be lifted through a hole in the throat plate:
1. The bobbin case may be improperly threaded.
2. It may not have been properly inserted
