All about overlock needles: In this post, you will learn everything about overlock needles and their special features. Also: what you should look for when buying them and how to use them.
Do you already know my blog post about sewing machine needles? In it, I reveal everything you need to know about sewing machine needles. Today, we want to talk about needles for the overlocker. Because these needles have some special features that you should pay attention to.
By the way: Here on SewSimple, there is a detailed guide on how you can sew curves and corners with the overlocker.
All about overlock needles: What you should know!
Why are overlock needles different lengths?
That is exactly right: the left needle of the overlocker is always positioned slightly higher than the right one.
How are overlock needles replaced?
When you replace one needle, you should replace the other one at the same time. It is likely that if one has, for example, accidentally sewn over a pin and broken, the other one is also defective. You don't always have to see this directly; often it only affects the quality of the seam.
When replacing, remember to always use two needles of the same type. Two different needles can result in an unattractive seam.
To change the needles, lower the presser foot, set the needles to their highest position, and loosen the screw with the screwdriver that was supplied with your overlocker.
If you have trouble with the limited space available for maneuvering, grab the needles with tweezers and insert them into the machine that way.
Check whether the needles are truly seated as far as they will go in the needle clamp. Then tighten the screw well and thread the machine.
What do I do if the overlock seam doesn't look good?
First, re-thread the overlocker. If that doesn't help: replace the needles!
Overlock needles are breaking! What should I do?
Check whether you might have sewn over a pin left in the fabric. Perhaps the layers of fabric are also too thick for your overlocker.
What distinguishes overlock needles from sewing machine needles?
Needles for the overlocker are harder and sharper. Why? Because the needles are designed for the higher sewing speed of the overlocker (and coverlocker).
How often do I have to replace overlock needles?
Don't just replace them in the event of an "accident." It is best to change the needles after about 6–8 hours of sewing. At the latest, when they no longer produce a nice seam, it is time to change them. :)
Do I have to use jersey needles when processing jersey on the overlocker?
This is a topic that always raises questions. The overlocker comes as standard with a specific type of needle. These are universal needles made specifically for overlockers and coverstitch machines.
Usually, these standard needles are perfectly suitable for virtually any fabric you might encounter as a hobbyist. Even stretch fabrics such as cotton jersey, sweatshirt fabric, or knits can be processed with these needles.
The reason: Universal needles have a slightly rounded tip and generally do not damage stretch knitwear.
However, it is possible that when working with very stretchy or delicate fabrics like viscose jersey or lyocell blends, you will get nicer results if you use jersey or stretch needles in your overlocker.
In case of doubt, you can simply try both and compare the results.
What does the designation SY mean on needles?
Petra Donath from Schmetz explains it this way:
The SY usually stands for the company Singer. At Singer, needles often only have their catalog number as a designation; the SY makes it clear that it is a Singer designation.
In the current Needle ABC, we have included the designations of other manufacturers under "alternative designation" to make it easier to choose the right needle.
Where can I buy overlock needles?
I order my overlock needles* online and always have some in stock for when they need to be replaced quickly again. Nothing is more annoying than not being able to continue a great sewing project because the machine is out of needles... ;)
What should I look for when buying overlock needles?
In your overlocker's instruction manual, there is a recommendation for which needles work best for that specific make. You can stick to that to be on the safe side.
You can also use the needles supplied with your machine as a guide. Special Babylock needles were supplied with my Babylock. However, my overlocker also sews fantastically with Schmetz overlock needles, which I can get everywhere.
I have already identified myself on the blog several times as a proponent of Schmetz needles. Please avoid using cheap needles from discount stores if possible. Only good needles provide beautiful sewing results in the long run.
