Needle threaders are used to ensure a clean, easy and safe sewing experience. It can be difficult to thread a sewing machine without the help of an automatic needle threader, as the eye of the needle is extremely tiny. Also, if a person does not have perfectly straight fingers, it may be difficult to pull the thread through.

With all of this in mind, it’s easy to see why an automatic needle threader would come in handy for just about everyone who sews from time to time. Overall, this makes it much more convenient for users, as they don’t have to worry about missing vital pieces of their projects due to a poorly threaded needle.

What is an automatic needle threader?

The purpose of needle threaders on sewing machines is to make threading needles easier for users. They are a small mechanism built into the machine, which allows for the needle to be threaded at a speed that is much quicker than it would take an individual who is unfamiliar with such tasks.

Threading a needle requires the use of a small arm that extends over the needle’s eye. On the bottom, there is a small opening that allows it to be slipped into place. Once in place, there are two pieces located on either side of the opening, which can be turned to move closer to each other. This movement locks the threader arm in place and allows it to continue holding onto the thread without allowing it to slip out.

Once this is accomplished, all that needs to be done is for it to be pulled up from underneath and threaded through the eye of the needle before being placed back down over it. The user can then proceed with stitching away as normal, knowing that their needle will always remain properly threaded for their next project.

The purpose of the automatic needle threader in most machines is not just to save time, but also to eliminate frustration and the risk of eye injury from attempting to hand-thread needles. It’s an easy-to-use device that almost anyone can use with little trouble – though some people may need practice typically because they don’t sew often enough.

How does an automatic needle threader work?

An automatic needle threader saves the user a lot of time. Instead of manually threading their needles, they can rely on the machine to do this for them. Once, I used Singer 3337 Machine and found it great to work with an automatic needle threader. I was frustrated with the process of threading a needle manually. This is especially helpful for those who are more familiar with other aspects of sewing and just need to focus more on what they are trying to make. These devices are also very easy to use, making them an excellent asset to any sewing machine.

The automatic needle threader itself is small and compact, usually being no more than a couple of inches long and taking up little to no room in a machine. The gears inside the device allow it to instantly adjust to the correct position over the eye of a needle. When this happens, the needle threader arm will be automatically locked into place; once this occurs, only an easy pull will be required to move it back out of position where it can be removed easily.

How to use an automatic needle threader?

The thread should stay near the eye of the needle. When you get to the last step, pull up on your hand wheel until your machine kicks into gear. Your needle should now have threaded through it!

Keep repeating this process until your needle is threaded. Here are some tips to get the best result from an automatic needle threader:

Needle Size Matters

Because a needle threader is designed to fit on various sewing machine needles, make sure you check for its size specifications. If your machine requires a .75 millimeter needle and your threader measures .80 millimeters, it won’t fit and it won’t work. The main thing to remember is to read the specs before you buy it.

Needle threaders are not designed to work with every type of thread. In fact, some types are too thick for it to handle and you can bend the arm out of shape if you push too hard. Because of this, make sure your thread matches the threader – sewing machine needle type and size-wise. And, before you start finger twirling, check that the thread is not frayed or tangled in any way – this can cause a jamming issue that won’t allow your needle threader to lock into place properly.

Finally, don’t forget that your sewing machine will only work correctly when it is threaded correctly. If you are using a slick thread and your needle is not inserted correctly, the threader won’t be able to tell that it’s there and will disengage. Make sure you’re using a needle threaded properly.

Some Common Fixes

It doesn’t mean that your needle threader can’t be fixed merely because it’s defective. There are a few common solutions to get this rolling again.

  • Push Down On The Threader Arm
  • Press Down On The Arm With Some Pressure
  • Turn The Arm Up A Bit

Needle Position Matters

Your needle threader won’t work if your needle hasn’t been placed correctly. Make sure your needle is at the top of the arm and that it is facing forward. If you have a top-loading bobbin, make sure there isn’t any thread in the bobbin before you try to thread it.

Make sure that the needle is positioned properly when you insert the thread into the machine. Then thread should be at least an inch or two away from where your needle is inserted. If not, the arm may be too far away from the eye of the needle when you pull it out, causing the threader to disengage.

Also, make sure the arm isn’t bent out of shape so it doesn’t hit your machine during use. If it is bent back (try pulling your arm down with a bit of pressure), this can cause issues as well.

You’ll know that everything is correct when you pull it back out and see that there’s no resistance as you push it into place.

Thread Matters

Your machine may not work with certain types of thread. Some thread is too thick for the automatic needle threader to handle effectively, which is why you should always make sure to check the specs on your machine and match it with the same type of thread.

If your needle threader won’t work even when you use proper thread, try using a thinner form of it. Thinner thread requires less force to push through and may pass through easier than thicker types.

FAQs about Automatic Needle Threader

How to fix an automatic needle threader if it is not working?

The first step is to check your needle for the proper size. The second step, check that your machine is threaded correctly. The third step, clean off any excess from the eye of the needle.

In the fourth step, discard any bent needle threader arms. The fifth step, clean off any threads that are in the holes of your machine because this can cause jamming in your machine.

If your machine doesn’t work with different types of thread, try a thinner type to make sure that it is not jammed with thick threads.

The first thing to do when you notice that your needle threader isn’t working is to check the position of your arm. The arm should be nearly perpendicular to the side of your machine and should be at least a couple of inches away from where the eye of the needle is inserted into place.

Why is my automatic needle threader not working?

If there is an excess of thread on the needle you are using, it could be causing the needle threader to jam. Sometimes the needle threader will not work with certain fabrics. If this happens remove the fabric and try again with a piece of scrap material to see if it works properly on a normal piece of fabric. If your machine isn’t working properly with different types of fabrics, try a thinner type to make sure that it is not jammed with thick threads. You may need to adjust how tight you have your machine threaded if it doesn’t work when you use thicker or thinner materials.

How do you thread an automatic threader on a sewing machine?

A sewing machine needle threader works by pulling the thread through the eye of the needle and then inserting a guide or sharp point that pulls the thread through to make it easier to pull. You may have to adjust how much pull you want on your needle.

What to do if the needle threader is not working?

If your needle threader is not working properly, the first thing you want to do is check the position of the needle threader. Make sure it is perpendicular to the side of your machine and about a couple of inches above where the eye of the needle is inserted. Next, make sure that it isn’t jammed with any excess thread. If there are any threads that are caught between the eye and guide, clear them out by using a pair of pliers or another tool to grab them and pull them through.

What to do if a sewing machine does not have an automatic needle threader?

Some sewing machines will not have an automatic needle threader. There is a way to do this by hand. First, you need to bring the thread up from the bobbin and out at the back of the machine. Then you need to tie a knot on top of where it comes out and make a loop so that it is easier to pass through as you pull through the eye of the needle.

Final Thoughts

An automatic needle threader can make a big difference in the quality of your sewing projects. These handy little items will help to do the tedious work for you so that you are able to focus on much more important things.

It is important to remember that the customer service for each company selling these items is very different and some may be better than others depending on how much you use your machines. It may be smart to purchase auto needle threaders from a company that also offers repair services or extra parts in case yours breaks down or gives trouble but it’s definitely worth investing in one.
