Industrial Sewing Machine Thread Tension Trouble-Shooting

What is an Industrial Sewing Machine?

Industrial sewing machines are used to sew heavy fabrics together. They are different than home sewing machines. Because they have a much higher stitch per minute (SPM) rate. This means that they can quickly sew through many layers of fabric. Industrial machines can also handle thicker threads. Which is necessary for sewing through heavy fabrics.

The industrial sewing machine is very common in our modern sewing industry. The industrial-type machine usually has a universal servo system, computer-controlled operation, and automation. Which improves the production efficiency of the sewing operation.

What are the most common stitch types of an industrial sewing machine?

Thick sewing machines are widely used for pattern sewing. There are two kinds of stitches for sewing machines very common. One is chain stitch and the other is lock stitch. We can check further info on these stitches here. 

For this lesson, we focus on lock stitch tension issues. Due to the sewing principle, you'll be able to fix another sewing machine or another stitch type in a similar way. Mini sewing machines are quite like the basic structure of industrial sewing machines. So do heavy-duty sewing machines. You can learn something from this article. And you'll have a clue to fix yours.

What are the different sewing results of top and bottom threads?

The two intersections are right in the middle of the sewing material. And the stitches are not tight or loose, neat and beautiful. In fact, there are various undesirable phenomena. In the sewing process of electronic pattern sewing machines, we'll get into this trouble a lot.

According to Sewschool, we can identify what are the correct thread tension. And what it looks like when it is too tight or too loose.



The industrial sewing equipment is incredibly durable. They can occasionally experience thread tension trouble. That is why we look into this article and get it fixed.

How to do thread tension: guiding video and tips

In this article, you'll learn how to adjust the thread tension. We will also be providing a handy video guide on how to do this. As well as some tips to help you get a perfect tension every time.

This JUKI DDL model is very commonly seen. sewing machine thread tension control is perfect for a professional or experienced sewer. The easy-to-use tension dial makes it easy to get the perfect tension for any fabric. And the stitch regulator ensures consistent stitching results. With this machine, you'll be able to sew with ease and confidence.



It can be tricky to get the tension just right. But with a little bit of practice and these helpful tips, you'll be able to sew like a pro in no time!

Here is the picture showing you how to do thread tension control:

For the upper thread, or say top thread, it's only doing the tension dials.

And for the tension diagram example, here's we can see:

When the upper thread is too tight, we'll go for the loose diagram.

When the upper thread is too loose, we'll go for the tight diagram.

It's quite simple in handling the tension thread in this way.

How do we do trouble-shooting for thread tension issues?

Sewing machines are a necessary part of many industrial and commercial sewing applications. Need to examine whether the tension in the sewing machine is adequate. And to produce superior seams. it is wise to always check the tension in the sewing machine. You need to follow a few simple steps. Then you can quickly and easily resolve any thread tension problems.

1. Surface thread too loose trouble:

The trouble might be the tension of the top thread is too big. Or might be the tension of the bottom thread is too small. End up the top thread will pull the bottom thread to the top of the sewing material. The intersection of the two threads will float on the sewing material. And the top thread is an obvious convex straight thread. Which is called a floating thread.

Solution: adjust the top thread tension dial to a smaller value. Just to relax the bottom thread tension. Or you can increase the bottom thread tension.

2. Bobbin thread too loose trouble:

When bobbin thread, as known as bottom thread, is too loose, it will "float" on the sewing material. And it makes the top thread appears as a straight line. It happens When the top thread tension is small. Or the bottom thread tension is too large. End up with the top thread is pulled under the sewing material. the intersection of the two threads is exposed under the sewing material. And the bottom thread forms a straight thread with the obvious bulge. Which is called floating bobbin thread.

Solution: increase the top thread tension or reduce the bottom thread tension.


3. Loose stitch trouble:

The tension between the top thread. And the bottom thread is relatively small. The intersection of the two threads is between the sewing materials. But the intersection of the top thread and the bottom thread is not close. It floats loosely on the top and bottom sides of the sewing material. If you pull it a little, there will be a gap between the two layers of sewing material.

Solution: appropriately increase the tension of top and bottom threads.

4. Wrinkling and shrinkage of sewing materials trouble:

The tension between the top thread and the bottom thread is too high. And the intersection of the two threads is between the sewing materials. But the shrinkage of the sewing materials is not straight. It happens a lot, especially the thin materials. And the sewing materials will break under a little force.

Solution: just reduce the tension between the top thread and the bottom thread.

5. Tension installation trouble: how to install a new thread tension accessory

Thread tension control is valuable to create everything from clothing to car upholstery. Sometimes we need to replace the old tension control unit. This video will show you how to install a new thread tension accessory:



Thread tension is an important factor in industrial sewing. Improper tension can cause skipped stitches, fabric puckering, and thread breakage. A thread tension accessory can help to ensure that the correct tension is maintained. This video will discuss the installation of a new thread tension accessory. And how to troubleshoot thread tension problems.

In conclusion, industrial sewing machine thread tension trouble-shooting can be a daunting task. However, by following these simple steps and tips, you can control the tension. And you'll have your machine running smoothly in no time. If you are still having trouble with your machine's tension, be sure to consult your manual. Or an industrial sewing machine technician for further assistance.
