What is a Bobbin In Sewing Machine?

In a sewing machine, a bobbin is a cylindrical component made of plastic or metal that holds the thread. It is placed inside the bobbin case, which located in the sewing machine's lower part. Bobbin thread is used to create the bottom layer or under a stitched layer, while spool thread is used for the top layer. As a result, these two threads interlock and create a sturdy stitch.

Using Purpose: What is a bobbin used for

The Purpose of a bobbin is to hold the thread used for the bottom layer of stitching. After the bobbin has been inserted into the bobbin case, the case is placed into the machine. During the stitching process, the needle pulls the thread from the bobbin to form the underlayer. Additionally, the bobbin provides tension to the thread, which controls how the thread is sewn into the fabric.

Types of Bobbins

Here are some common types of bobbins and their specific uses:

Plastic Bobbins: 

These are the most common type of bobbins and are used in most domestic sewing machines. They are lightweight, inexpensive, and come in a variety of colors.

Metal Bobbins:

These bobbins are more durable than plastic bobbins, but they are also heavier. They are typically used in industrial sewing machines or for heavy-duty projects.

Pre-Wound Bobbins: 

These bobbins are pre-wound with thread, making them convenient for quick projects or when you run out of thread while working on a project. You can choose from a variety of colors and thread types.

Magnetic Bobbins: 

These bobbins have a small magnet inside, which holds the bobbin in place inside the bobbin case. This helps to prevent tangling and makes threading the bobbin easier.

L Style Bobbins:

These bobbins have a "L" shape and are used in some specific types of sewing machines like Janome, Brother, Babylock, etc. They slightly differ in size and shape compared to regular round bobbins.

Class 15 Bobbins: 

These bobbins are slightly larger than regular bobbins and are used in some older models of sewing machines. They are less common than the other types of bobbins.

It is important to note that different sewing machines require different types of bobbins, so check the manual or consult the manufacturer to determine the correct type of bobbin for your machine. Using the wrong type of bobbin can result in tangling, breaking, and uneven stitching.

Loading and Threading the Bobbin

Loading and threading the bobbin is an important step in the sewing process, as it ensures that the bobbin is properly loaded and threaded so the machine can sew correctly. Generally, loading and threading a bobbin involves the following steps:

• First, remove the bobbin case from the machine by either opening the front cover or sliding it out from the side of the machine.

• Next, wind the thread onto the bobbin. Hold the end of the thread and wind it around the bobbin several times, ensuring that the thread is wound tightly and evenly.

• Once the bobbin is wound, insert the bobbin into the bobbin case, ensuring that the thread is coming off the bobbin in a clockwise direction.

• Now insert the bobbin case into the machine, making sure that it is securely in place.

• Raise the presser foot and thread the machine according to the machine's manual instructions.

• Lower the presser foot and hold the top thread while gently turning the hand wheel or pressing the foot pedal to bring the needle down into the bobbin case.

• Hold the top thread and pull it up to bring the bobbin thread up.

• Hold the two threads together and gently pull them to the back of the machine.

Following these steps will ensure that your bobbin is properly loaded and threaded, leading to smooth and professional-looking stitches on your projects.

Troubleshooting Bobbin Issues

Bobbin issues are a common problem faced by many sewers and can cause frustration and delay in completing projects. Here are some common bobbin problems and solutions to fix them:

Tangling:     One of the most common bobbin issues is tangling. This can occur when the bobbin is not loaded or threaded correctly or if the tension needs to be set correctly. To fix this problem, check the manual to ensure that the bobbin is loaded and threaded correctly, and adjust the tension as needed. Also, check that the bobbin is clean and free of lint or debris.

Thread breaks:     Another common problem is thread breaks. This can occur when the thread is not wound tightly and evenly on the bobbin or if the thread is old or damaged. To fix this problem, rewind the bobbin with fresh thread, and make sure that the thread is wound tightly and evenly.

Skipping stitches:    Skipping stitches can occur when the bobbin is not inserted correctly into the bobbin case or if the tension is not set correctly. To fix this problem, check the manual to ensure that the bobbin is inserted correctly, and adjust the tension as needed.

Bobbin case jammed:     Sometimes, the bobbin case gets jammed and can be difficult to remove. To fix this, clean the bobbin case and check that it is not bent or damaged. Also, ensure that the bobbin is inserted correctly and that the machine is in good working order.

Running out of thread:     This can occur if the bobbin is not wound correctly or if you use a low-quality thread. To fix this, rewind the bobbin with fresh thread, and make sure that the thread is wound tightly and evenly.

Uneven stitching:     If the stitching is uneven, it could be caused by a loose or damaged bobbin case or a worn or damaged needle. To fix this, check the bobbin case and needle and replace them if necessary.

Understanding the common bobbin problems and the solutions to fix them can save time and frustration while working on your sewing projects.

Maintenance and Care of Bobbins

Proper maintenance and care of bobbins are essential to ensure they last a long time and work correctly. Here are some tips for maintaining and caring for your bobbins:

Clean bobbins regularly:     Dust, lint, and debris can accumulate on bobbins, causing them to malfunction. Clean bobbins by wiping them down with a dry cloth or a brush to remove debris.

Keep bobbins dry:     Moisture can cause rust and corrosion on metal bobbins and cause plastic bobbins to become brittle. Avoid storing bobbins in damp or humid areas.

Store bobbins properly:     Proper storage is important to keep bobbins in good condition. Keep bobbins in a container or bag to prevent them from becoming tangled or lost.

Use the correct bobbin for your machine:     Different types of machines require different types of bobbins. Be sure to use the correct type of bobbin for your machine, as using the wrong type of bobbin can cause damage to the machine or the bobbin.

Check the tension: Regularly check the bobbin thread's tension, as incorrect tension can cause problems such as tangling or uneven stitching.

By following these simple tips, you can ensure that your bobbins remain in good condition and work correctly, saving you time and money in the long run.

Difference Between Bobbin and Spool

A bobbin and a spool are both used in sewing machines, but they serve different purposes and have different characteristics.

A bobbin is a small, cylindrical piece of plastic or metal that holds thread and is used for the bottom layer of stitching. The bobbin is inserted into the bobbin case, and then the case is placed into the machine.

On the other hand, a spool is a larger cylindrical piece of plastic or cardboard that holds thread and is used for the top layer of stitching. Thread from the bobbin forms the stitch's bottom or underlayer as it feeds through the machine's tension and onto the needle.

Bobbins and spools are different according to the project and machine. For most sewing projects, both a bobbin and a spool are needed. Under the machine's tension, the bobbin creates the stitch's bottom layer, while the spool's thread creates the top layer. However, for some specific sewing machines, the machine can wind the spool's thread onto the bobbin.
