How To Thread Bobbin On Singer Sewing Machine

Section 1 – Preparing for Threading the Bobbin

Before starting to thread the bobbin on a Singer sewing machine, sewers should make sure that the presser foot is raised, the feed dogs are disengaged, and the spool of thread is secured on the spool pin. It is important to ensure that the bobbin is placed correctly in the bobbin case, otherwise the threading will be impossible. Sewers should also raise the needle applicable to the singer machine model and choose the desired thread tension and stitch length.
The first step in threading a bobbin on a Singer sewing machine is to take out the bobbin and more thread onto the bobbin, up to the indicated line. To keep the thread consistent, sewers should wind the bobbin with even tension, forming multiple layers. Once this is finished, they should cut the thread tail and make sure that easily-moveable bobbin winder is on the lower side of the sewing machine.

Section 2 – Threading the Bobbin on the Singer Sewing Machine

The bobbin should now be placed underneath the foot plate of the Singer sewing machine and the entire thread should be moved to the position where the bobbin starts winding. The empty bobbin should be placed on the bobbin winder slot until it clicks and the bobbin is secured. Now the bobbin winder is secured firmly with the threadpath control lever. Depending on the Singer model, the threadpath control lever should be moved in the forward or backward direction to start winding the bobbin. Once the bobbin is wound, the bobbin winder can be disengaged and the thread path should be changed back to its original position.

Section 3 – Moving the Thread Through the Placeholder

Once the bobbin is wound, sewers should place it inside the bobbin case if it has one, otherwise the bobbin can be secured in the Singer machine without it. Initially, there should be no tension on the bobbin thread. Then, sewers should pull the bobbin thread from the bobbin and move it under the presser plate source hole. Here, the thread should be placed in the hole which is indicating the thread path for the needle. Then, sewers should move the thread through the placeholder and the thread should be pulled to the back side. The machine should now be set up for winding the upper thread on the Singer sewing machine.

Section 4 – Securing the Thread

The next step is to secure the thread on both the upper and lower thread. Put the spool of thread at the thread socket of the machine and then press the needle threader button. Here, the thread should fit snuggly into the eyelet of the needle threader. The needle threader should then be dropped until it reaches the eye of the needle. Once this is done, the thread should be pulled up to the top that is of the same side as the plane of the needle.
Following this, the thread should be pulled down towards the presser foot and placed through the eyelet below the presser foot. Here, sewers should ensure that the presser foot does not cut the thread. Then, the thread should be placed in the take-up lever, the eye of the bobbin, and the bobbin case. This then completes the threading procedure of the bobbin on the Singer machine.

Section 5 – Checking the Thread Tension

To ensure that the bobbin is properly threaded, sewers should check the tension on the upper and lower Thread. This is usually done by pushing down on the foot pedal and spinning the handwheel. When the thread is not properly tensioned, sewers should check the tension and make appropriate adjustment accordingly. This is done by turning the knurled knob of the thread tension disk either side. When needle and bobbin threads form a loop at the bottom of the fabric, it indicates that the thread tension is correct. Once the thread tension is adjusted, sewers can continue with their work.

Section 6 – Cleaning and Maintaining the Bobbin

To keep the bobbin in good condition and make sure that it performs efficiently, sewers should take out the bobbin and clean it after each use. Cleaning the bobbin includes removal of any lint that may be formed from the thread or fabric. Additionally, it is important to ensure that the bobbin is not rusty because this can cause the thread to break during sewing. Sewers should also check for any thread tails left in the bobbin case after every use.

Section 7 – Replacing the Bobbin

If sewers notice that the bobbin is getting worn out or the thread is not spinning, it is time to replace it with a new bobbin. All Singer models come with new bobbins of the same size, however, sewers may also purchase an appropriate sized bobbin to fit their machine. Once the new bobbin has been inserted, it should be threaded as described above.

Section 8 – Troubleshooting

If the thread on the upper and lower bobbin are not even, sewers should check if the thread is wound too tightly on the bobbin. Additionally, they should also make sure that the bobbin thread is not pulled too tightly while threading through the holder. If the thread is still uneven, sewers should rethread both the bobbin and upper threads to ensure the tension is correct.

Section 9 – Changing Needles

Sewers should also change the sewing machine needles at regular intervals to ensure that their machine functions properly. Singer needles come in different sizes to accommodate different types of fabric and thread. The size of the needle should be determined by the type of fabric and thread being used. If the wrong size of needle is used, it can cause thread breakage, uneven thread tension, and fabric puckering.

Section 10 – Special Singer Bobbins

For certain Singer machines, sewers may need to purchase special bobbins for embroidery and other decorative stitching. These bobbins are usually made of plastic and have a larger capacity, which is ideal for stitching crosses and other decorative stitching. Additionally, some models may require a drop-in bobbin, which is easier to thread and does not require the bobbin to be wound manually.
