Preparation
Adding a bobbin to a sewing machine is quite a simple task, but it requires careful attention and preparation. To begin, gather up all the required materials, such as a bobbin, winding thread and a flat or circular surface to hold the materials. Once the materials are positioned and ready to go, locate the bobbin and bobbin winder, which is generally located on top of the machine.
Next, ensure that the machine is unplugged from the power source for safety. Check the bobbin case for proper fit, ensuring the bobbin glides in and out smoothly. Before installation, make sure to remove any lint or dust, as this can prevent proper function.
Threading
Once everything is in order, thread the machine by following the instructions in the user’s guide. Ensure the bobbin thread is correctly in place to begin winding. Many machines are designed with an automatic winding stopper, which removes the excess tension and strain when winding.
If the machine does not have the automatic stopping feature, it is important to take careful measurements. Generally, the bobbin should measure fifteen to twenty-five centimeters in circumference to ensure even tension throughout. Inspect the spool pin and bobbin case for correct placement, ensuring the spool pin is facing away from the tension spring.
Filling the Bobbin
With the thread correctly in place, start to wind the thread around the bobbin by rotating the machine. Once the bobbin is rounded, push down the bobbin to secure it into place. Slowly rotate the machine so the bobbin fills up with the thread from the top. It is important to keep a firm grip on both the thread and bobbin case so as to not let the bobbin pop out.
When the bobbin is sufficiently full, cut the thread and tie it off to the bobbin itself. This will keep the bobbin secure and prevent the thread from becoming tangled or knotted during the sewing process.
Installation
With the bobbin filled, flip open the bobbin case and place the bobbin into its compartment. Don’t forget to include the thread in the bobbin case as well; otherwise the bobbin will not function properly. Secure the bobbin in its casing and ensure the thread is free from any tangles. Again, ensure the bobbin is in the correct direction and is able to move in and out freely.
When the bobbin is fitted, test the bobbin case by rotating it slowly a few times. If there is any resistance, then something is wrong and the bobbin should be taken out and checked.
Final Test Run
Finally, finish off the task by connecting the machine to the power source. Test the machine by sewing on a scrap fabric to ensure the bobbin is correctly functioning. If the machine is correctly threaded and the bobbin correctly installed, the stitching will run smooth and the bobbin should wind evenly.
Reviewing Tips
To make sure the sewing process always runs smoothly, review the bobbin system every time before starting a project. Begin by checking if the bobbin is fitted correctly in its casing and that the thread has been wound correctly. Once the bobbin is filled, ensure it can still rotate freely; if not, take out the bobbin and re-fill it.
When winding the bobbin, always try to follow the instructions found in the user’s guide. Keep in mind that an incorrectly wound bobbin can cause tension complications, damage to the fabric, and uneven stitches.
Troubleshooting
At times, the bobbin can become jammed in the machine, especially when using a thick or stretchy material. Dust & Lint are the main culprits that can cause problems when placing the bobbin into its casing. Try taking out the bobbin and blowing out any excess dirt & dirt or using a small brush to sweep away dirt & lint.
When placing the bobbin back into the machine, there is usually a black mark painted on the side of the bobbin case. To ensure a successful stitch, make sure the bobbin is spinning in the same direction as the black mark.
Designated Station
Having a designated station to store the bobbins is also a good idea as it allows for smooth workflow. Use containers to separate the bobbins and accessories, such as sewing scissors and spools or bobbins and threads. This method can save time as you will always know exactly where the items are stored, this will in turn reduce the time it takes to fill and install the bobbins.
Clip up some colorful thread cards and pin them on the wall for an easy visual reference for thread and bobbin color. This can also come in handy when selecting materials for projects, as all the necessary accessories can easily be located.
Storing Bobbins
When storing bobbins, it is important to ensure they remain dust-free. A plastic box with a lid is a great storage solution as it keeps bobbins out of sight and away from any dust settling on them. Make sure to insert foam into the box to keep the bobbins from rattling against each other, this will also keep them in mint condition.
Popular bobbin storage methods also include pinning them to a magnetic surface or using a mesh grocery bag to keep them together. How you store the bobbins is up to the user and what works best to keep them protected and organized.
Material Considerations
Keep in mind that each fabric or material requires its own specific bobbin. For example, metallic threads are often accompanied by a metallic bobbin while monofilament threads may use a specialized bobbin. When selecting bobbins, consider the fabric weight and thickness, as well as the stitch pattern to ensure the proper bobbin is used.
Also, when dealing with less common bobbin types, such as the clear bobbins, it is advisable to research the best sewing techniques for that particular material. Understanding the properties of different materials and fabrics can save time and reduce the chances of common sewing mistakes.
Bobbin Thread
Always make sure to use the correct thread for the bobbin; thin thread on a thick bobbin or thick thread on a thin bobbin can lead to major tension problems while sewing. If in doubt, refer to the brand and model number of the machine and look up the ideal thread type and size to use.
When using multiple bobbins in a single project, consider using the same type of thread throughout. This will ensure a consistent stitch and will help prevent added tension on the fabric.
Tension Adjustment
The tension of the bobbin will require periodic adjustment in order to maintain a balanced and even stitch. If the tension is too tight, the fabric might bunch up or the stitches may be pulled too tight, which can be both uncomfortable and unsightly. If the tension is too loose, the stitches may be too lax or the fabric may sag.
In order to make an adjustment, locate the tension mechanism inside the bobbin case. In most machines, it is located on the side or back of the bobbin case. Move the dial to the corresponding tension number on the dial to customize the tension as per need.
If the needles are consistently breaking or skipped stitches appear, it is likely the tension needs to be adjusted to a lower number. If the stitches appear bulky or too tight, adjust the number to something higher than the current setting.
