How to Use the Bobbin Winder of Embroidery Machine

Today, we’ll show you how to use the bobbin winder on the E15 Embroidery Machine. The bobbin winder is a small but essential accessory — it lets you refill bobbins evenly and consistently, so your embroidery runs smoothly from start to finish. Whether you’re just getting started with your embroidery machine or you’ve been stitching for a while, knowing how to wind a bobbin properly saves you time and prevents tension problems during embroidery.

This is the final lesson in our 15-part E15 tutorial series. If you’ve followed along from the beginning, you now have a complete foundation for embroidery on the E15.

Bobbin Winder Components

First, let’s take a look at the bobbin winder components:

• Bobbin winder unit
• Spool support rod with nut/washer
• Thread hook with nut
• Spool plate
• Foam pad

Step 1: Assemble the Bobbin Winder

1. First, remove the nut and washer from the bottom of the spool support rod.

2. Install the spool plate, foam pad, and washer in the order shown.

   

3. Insert the spool support rod into the base and tighten the nut securely.

   

4. Insert the nut into the mounting hole, and attach the spool support rod to the base.

   

5. And tighten the nut to secure the spool support rod.

   

6. When the thread guide hook is parallel to the support, tighten it securely with the Allen wrench.

   

Step 2: Start Winding the Bobbin

1. Place an empty bobbin onto the winding shaft and push it all the way in.

   

2. Make sure the bobbin and shaft rotate together. If they don’t, the bobbin may be too large.

3. Place the bobbin thread spool onto the spool plate.

4. Thread the bobbin thread through the spool support rod.

   

5. Wind the thread around the empty bobbin 3–5 turns, starting from the bottom and working upward.

   

6. Make sure the thread feeds smoothly without tangling, looping, or catching on any parts.

   

7. Turn on the bobbin winder.

   

8. We recommend setting the time between 15–25 seconds.

   

9. Press Start to begin winding.

   

10. The machine will stop automatically when the timer ends, or you can press Stop to stop manually.

    

Step 3: Bobbin Winder Tips

Bobbin thread is uneven

If the bobbin thread is uneven, first check if the thread guide position is aligned with the center of the bobbin.

Follow these steps to adjust:

1. Turn off the bobbin winder.

2. Loosen the screws on the thread guide assembly.

   

3. Slightly adjust the thread guide position until the thread outlet aligns with the bobbin center.

   
4. Tighten the screws after adjustment.
5. Wind the bobbin again and check that the thread is smooth and evenly distributed.

Bobbin won’t fit onto the bobbin winder shaft

If the bobbin won’t fit onto the bobbin winder shaft, gently squeeze it with needle-nose pliers.

If it feels too loose, use a flat-head screwdriver to open it slightly.

That’s it for today!
