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.
Assemble the bobbin winder by installing the spool plate, foam pad, washer, and spool support rod.
Push the empty bobbin all the way onto the winding shaft and confirm it rotates with the shaft.
Always turn off the bobbin winder before installing, threading, or handling the bobbin.
Wind the thread around the empty bobbin 3–5 turns before starting.
Recommended winding time: 15–25 seconds. Adjust slightly based on thread type and tension.
If the bobbin thread is uneven, check that the thread guide aligns with the bobbin center.
If the bobbin won’t fit the shaft, adjust it with needle-nose pliers or a flat-head screwdriver.
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
First, remove the nut and washer from the bottom of the spool support rod.
Install the spool plate, foam pad, and washer in the order shown.
Insert the spool support rod into the base and tighten the nut securely.
Insert the nut into the mounting hole, and attach the spool support rod to the base.
And tighten the nut to secure the spool support rod.
When the thread guide hook is parallel to the support, tighten it securely with the Allen wrench.
Step 2: Start Winding the Bobbin
Place an empty bobbin onto the winding shaft and push it all the way in.
Make sure the bobbin and shaft rotate together. If they don’t, the bobbin may be too large.
Place the bobbin thread spool onto the spool plate.
Note: Turn off the bobbin winder before installation, threading, or handling the bobbin.
Thread the bobbin thread through the spool support rod.
Wind the thread around the empty bobbin 3–5 turns, starting from the bottom and working upward.
Make sure the thread feeds smoothly without tangling, looping, or catching on any parts.
Turn on the bobbin winder.
We recommend setting the time between 15–25 seconds.
Note 1: Thread type and tension may vary, so we recommend starting around 15–25 seconds and adjusting slightly as needed.
Note 2: 1.0 and 1.6 refer to bobbin size. 1.0 bobbin: about 10–15 seconds. 1.6–2.0 bobbin: about 30–37 seconds.
Press Start to begin winding.
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:
Turn off the bobbin winder.
Loosen the screws on the thread guide assembly.
Slightly adjust the thread guide position until the thread outlet aligns with the bobbin center.
Tighten the screws after adjustment.
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!

How long should I wind a bobbin on the E15 embroidery machine?
We recommend setting the time between 15–25 seconds. For a 1.0 bobbin, about 10–15 seconds; for a 1.6–2.0 bobbin, about 30–37 seconds. Thread type and tension may vary, so adjust slightly as needed.
Why is my bobbin thread uneven?
If the bobbin thread is uneven, first check whether the thread guide position is aligned with the center of the bobbin. If not, turn off the bobbin winder, loosen the screws on the thread guide assembly, adjust the position until the thread outlet aligns with the bobbin center, then tighten the screws and wind again.
What should I do if the bobbin won’t fit onto the bobbin winder shaft?
If the bobbin won’t fit, gently squeeze it with needle-nose pliers. If it feels too loose, use a flat-head screwdriver to open it slightly.
Can I handle the bobbin while the bobbin winder is running?
No. Turn off the bobbin winder before installation, threading, or handling the bobbin.
How do I know the bobbin and shaft are engaged correctly?
Make sure the bobbin and shaft rotate together. If they don’t, the bobbin may be too large.
