How to Wind a Bobbin on Sewing Machines with Top Loading Bobbin System

Presented by Rachel from Curly Quilt

Applicable Machines

• Demonstrated on Janome Skyline S9
• Principles applicable for any top loading bobbin system

Materials Needed

• Good quality spool of thread
  • Recommended brands:
    • Mettler Silk Finish Cotton
    • Polyester threads
    • Aurifil
    • Gutermann (from Joann's)
    • Sulky
  • Avoid: Coats and Clark or Dual Duty (not suitable for computerized machines)

Setup for Winding a Bobbin

1. Thread Selection:

   • Use a high-quality thread for better machine performance.
   • Poor quality threads can lead to frequent re-threading and machine issues.

2. Thread Placement:

   • Place the thread spool with a spool cap to secure it.
   • Ensure the spool cap is appropriately sized to prevent tangling.

3. Threading the Bobbin:

   • Pinch the thread to maintain tension while winding.
   • Follow the machine’s threading guide, which may be printed on the machine.

Bobbin Winding Process

1. Prepare the Bobbin:

   • Use a Class 15 plastic bobbin for Janome machines.
   • Avoid metal bobbins; they are not ideal for machines with plastic bobbin cases.

2. Threading the Bobbin:

   • Insert the thread through the bobbin hole.
   • Position the bobbin on the winder, ensuring it clicks into place.

3. Winding the Bobbin:

   • Engage the bobbin winder and press start.
   • Increase speed to full using the machine’s start/stop button for consistent tension.
   • Clip the starting thread and let the bobbin wind.

4. Checking Bobbin Fullness:

   • If the bobbin does not fill fully, adjust the stopper.
   • Stop manually when the bobbin is full.
   • Ensure the thread is tightly and evenly wound.

Troubleshooting

• If thread gets caught:
  • Remove the winder arm, clear the thread, and replace it.
  • Align notches when reattaching the arm.

Installing the Bobbin

1. Removing Bobbin Cover:

   • Slide the cover to access the bobbin case.

2. Inserting the Bobbin:

   • Ensure the thread is on the left, resembling a ‘P’ for perfect tension.
   • Follow the machine’s diagram to position the thread.
   • Swing the thread under metal arms for proper tension.

3. Completing Installation:

   • Snip excess thread using the thread cutter.
   • No need to pull up the thread manually.
