- Insert an empty bobbin onto the bobbin winder spindle.
Steps:
- Thread the Machine: Pull the thread from the spool and guide it through the thread guide on the machine. Pass the thread through the bobbin winder tension disc and onto the bobbin.
- Start Winding: Depress the bobbin winder pedal or lever to start winding the thread onto the bobbin. Hold the thread taut to ensure proper tension.
- Continue Winding: Keep the bobbin winder running until the bobbin is completely filled. Avoid overfilling, as it can cause problems during sewing.
- Secure the Thread: Once the bobbin is filled, cut the thread close to the bobbin and remove it from the winder.
Additional Tips:
- Use high-quality thread that is compatible with your fabric and sewing machine.
- Wind the bobbin at a moderate speed to prevent tangles or thread breakage.
- Check the bobbin tension regularly to ensure optimal stitch quality.
Assembling the Bobbin Case into the Machine
The bobbin case is a small, removable part of the sewing machine that holds the bobbin and guides the thread through the machine’s hook. To assemble the bobbin case into the machine:
Step 1: Open the bobbin case latch
Locate the bobbin case latch on the front of the machine. It is typically a small, lever-like button or latch. Press the latch to open it and release the bobbin case.
Step 2: Insert the bobbin case
With the latch open, insert the bobbin case into the machine’s bobbin case chamber. The chamber is usually located underneath the needle plate. The bobbin case should fit snugly into the chamber.
Step 3: Set the bobbin thread guide
The bobbin thread guide is a small, metal or plastic arm that guides the thread from the bobbin to the hook. Locate the bobbin thread guide and set it in the correct position according to the machine’s instructions. The guide typically has a small notch or groove that aligns with the thread path.
Step 4: Draw up the bobbin thread
With the bobbin case assembled, draw up the bobbin thread by pulling it through the thread path and up to the needle.
Step 5: Close the bobbin case latch
Once the bobbin thread is drawn up, close the bobbin case latch to secure the bobbin case in place. The latch will typically click or snap into place.
| Issue | Cause | Solution |
|---|---|---|
| Bobbin thread is not being picked up by the hook | Bobbin thread is not threaded correctly | Check the bobbin thread path and make sure it is threaded correctly through the bobbin case and thread guide |
| Bobbin case is not assembled correctly | Bobbin case is not properly inserted or the bobbin thread guide is not set correctly | Reassemble the bobbin case and check that the bobbin thread guide is in the correct position |
Threading the Bobbin Case
Once we’ve finished winding the bobbin, we now need to thread this into the machine for use. First, we need to access the bobbin case. The details for this process will depend on your machine model, and if in doubt, refer to the manufacturer’s instructions. However, in general terms, it is usually by accessing a panel at the front of the machine and hooking a small latch to release the bobbin compartment. Once removed, the bobbin case is a small, round housing. To prepare the thread, follow the following steps:
| Step | Description |
|---|---|
| 1 | Pull the thread under the spring-loaded finger and guide it into the slot on the bobbin case. |
| 2 | Continue to wind the thread around the tension disc, and then secure it in the notch opposite the starting point. |
Guiding the Thread through the Tension Discs
Once the bobbin is in place, the next step is to guide the thread through the tension discs. This is what helps to control the tension of the thread as it is sewn, ensuring that it is not too loose or too tight. Here’s how to do it:
- Locate the tension discs. They are usually located on the top of the sewing machine, near the needle.
- Identify the thread guide. This is a small, usually metal piece that guides the thread into the tension discs.
- Insert the thread into the thread guide. Make sure that the thread is going in the correct direction, as indicated by the arrows on the guide.
- Pull the thread through the tension discs. There should be some resistance, but not too much. You should be able to pull the thread through with a gentle tug.
- Adjust the tension as needed. If the tension is too tight, the thread will break easily. If the tension is too loose, the stitches will be loose and uneven.
| Tension too tight | Tension too loose |
|---|---|
| Thread breaks easily | Stitches are loose and uneven |
Once the thread is properly tensioned, you can start sewing. If you encounter any problems with the tension, refer to your sewing machine’s manual for more troubleshooting tips.
