- Place two spools of thread on the spool stand.
3. Threading the Machine
- Pull the thread straight up from the spool and go from back to front through the top guide holes.
- Pull the right-hand side spool thread down to the bobbin winder.
- Guide the thread from right to left through the guide hole and under the tension discs on the bobbin winder.
- Place an empty bobbin on the spindle.
- Push the automatic stop lever forward to engage the wheel to the drive belt.
- Pull the thread under the bobbin and wrap it around a few times.
- Create a loop and a half hitch over the side of the bobbin spool.
- Press the foot pedal to wind the bobbin until it is fully filled.
- Cut the thread.
4. Preparing for Sewing
- Take the full bobbin from the spindle and secure the thread lightly into the bobbin threads so that it does not unwind.
- Set the full bobbin aside.
- Place another bobbin on the spindle and repeat the winding process.
- Pull the left thread down towards the post on the top of the machine.
- Go through the hole from back to front and then over the top through the tensioning discs.
- Pass the thread through the top hole of the top thread guide from right to left.

- Move the knee lever to open the discs for easy thread insertion.
- Pull the thread up and engage the take-up spring.
- Thread through the take-up armhole from right to left, pull down through the left guide, and come down toward the needle.
- Go around the guide on the right of the needle bar and then through the hole on the front of the needle bar.
5 Needle Insertion and Presser Foot Attachment
- Insert the needle fully into the needle bar, ensuring the groove faces are left and the scarf or notch faces are right.
- Adjust the needle position using the adjustment screw.
- Insert the presser foot by lifting the presser bar with the knee lever, placing the foot, and then lowering the presser arm.
- Tighten the screw to secure the presser foot.
6. Bobbin Preparation and Placement
- Open the bobbin case cover.
- Hold the bobbin by the lever and press it fully into the rotary hook assembly.
- Ensure it is firmly seated.
- Hold the upper thread and manually rotate the wheel towards you, pulling the top thread until the lower bobbin thread comes up.
- Use a screwdriver or seam ripper to guide the lower bobbin thread up.
- Pull both threads through the middle of the presser foot and out the back of the machine.
- Close the cover plate.
7. Testing and Adjusting Tension

What Is an Industrial Sewing Machine?
An industrial sewing machine is a heavy-duty sewing machine designed for commercial and industrial use. It is specifically built to handle high-volume sewing tasks and work with various types of heavy fabrics and materials. Industrial sewing machines are commonly used in factories, garment production units, and other manufacturing settings where efficiency, speed, and durability are crucial.
Here are 10 key features of industrial sewing machines:
- Industrial sewing machines are made with strong and durable materials, such as cast iron or steel, to withstand heavy use and provide stability during high-speed sewing.
- These machines are engineered to operate at much faster speeds compared to standard household sewing machines. They can stitch hundreds or even thousands of stitches per minute, increasing production efficiency.
- Industrial sewing machines are equipped with powerful motors that generate sufficient torque to sew through thick and heavy materials like leather, denim, canvas, and upholstery fabrics.
- Depending on the model, industrial sewing machines can offer a wide range of stitch types, including straight stitches, zigzag stitches, overlock stitches, chain stitches, and more. This allows for versatility in garment construction and finishing.
- Industrial sewing machines often have a larger work area or sewing bed, providing ample space for handling bulky fabrics or large-scale projects.
- These machines can accommodate various specialized attachments and accessories for specific sewing tasks, such as binding, piping, ruffling, or zipper installation.
- Industrial sewing machines are designed for continuous operation, allowing them to handle long sewing sessions without overheating or experiencing mechanical issues.
- Industrial sewing machines often feature automatic functions and minimal manual adjustments, such as automatic thread trimming, backstitching, and thread tension control. This enhances efficiency and reduces downtime.
- Some industrial sewing machines can be customized to meet specific production requirements, allowing for adjustments in stitch length, stitch width, thread tension, and other settings.
- Due to their robust construction, industrial sewing machines are built to withstand heavy use over an extended period. They are designed for longevity and can withstand the demands of commercial sewing environments.
How do you bring the bobbin thread up in the JUKI buttonhole machine?
Not only you can sew but bring the bobbing thread up in your JUKI buttonhole machine by following these steps:
Step 1
- Start by ensuring that the take-up lever of your sewing machine is in the highest position. This is important for proper thread tension and to avoid any issues or jams.
- Roll the hand wheel towards you, following the arrow on it. Beginners often make the mistake of pushing it away, which can cause problems.
- Roll the wheel towards you until the take-up lever reaches the highest position possible.
Step 2
- Once the take-up lever is in the highest position, take your thread and pull it underneath the presser foot towards the back.
- Pull the thread for about five inches and note the tension. It should feel a little tight but not overly loose or too tight.
- If the thread feels too loose, it may not be properly inserted into the tension mechanism. Adjust it if necessary.
Step 3
- Practice pulling the thread to become familiar with good tension and bad tension. This will help you determine if your machine is threaded correctly before starting to sew.
- Good tension allows the thread to move smoothly, while bad tension may cause the thread to get stuck or break.
- Pull the thread to test the tension and get a feel for what is right.
Step 4
- Note that if the take-up lever is down, the thread will be locked and won’t come through.
- To test the thread tension, ensure that the take-up lever is up. If you pull the thread and it doesn’t come through, the tension is too tight.
- Avoid pulling the threads towards you, as this can bend the needle. Always put the thread underneath the presser foot, resting against it rather than the needle.
Step 5
- To pull up the bobbin thread, make sure your machine is threaded correctly, and the take-up lever is in the highest position.
- Hold the thread with a little tension and turn the hand wheel towards you to take one stitch.
- One stitch occurs when the take-up lever completes one full rotation, moving down and then back up.
Step 6
- Avoid the misconception that one stitch means the needle goes down and comes back up. This is actually only half a stitch.
- To pull up the bobbin thread, you need to turn the hand wheel until the take-up lever reaches the top position.
- Ensure the take-up lever is at the highest point for successful thread retrieval.
Step 7
- Keep turning the hand wheel until the take-up lever is all the way up.
- It’s essential not to rush this step. Make sure the take-up lever is at the topmost position before proceeding.
Step 8
- Pull the thread gently and look for a loop that pops up.
- The loop may be small, but it’s the indicator that the bobbin thread is coming up.
- Continue pulling the loop until you find the end of the loop, which consists of two full threads representing the bobbin thread.
Step 9
- Take both threads (the top thread and the pulled-up bobbin thread) and put them underneath the presser foot, pulling them towards the back.
- Ensure the threads are positioned correctly to allow sewing on both the top and bottom sides of the fabric.
Step 10
- Before starting to sew, remember to lower the presser foot.
- If the presser foot is still up, lower it using the lever located at the back of the machine or any other appropriate mechanism your Juki sewing machine might have.
Step 11
- Now you’re ready to insert your fabric and begin sewing with the correctly pulled-up bobbin thread and properly positioned top thread.
- Always double-check that the presser foot is down before you start sewing to avoid jams and ensure smooth stitching.
