An overlock sewing machine is used to create an over locking stitch on cloths with ease. Hemming, edging and seaming is done at the edge of the cloth by over lock stitching and prevent the cloth from unraveling. Also, it is using to sew together along with hemming as per the stitching requirement.
In North America, the overlock sewing machines are also known as Serge, but in the rest of the world, a serger sewing machine is known for overlocking, hemming and trimming features. An overlock sewing machine helps you to obtain a professional style of stitching within no time.
An overlock sewing machine uses one to five threads, and it mainly uses loop threads that make it easy to lock the needle thread in correct place. You can create different stitches and different looks with more threads. Overlock is the main kind of stitch that can be made out on an overlock sewing machine and the machine is named after the overlock sewing machine.
1. Thread the machine in proper order
The first and significant step while using an overlock sewing machine is to thread it correctly because there are one to five spools of thread depending on the types of overlock system are using. A three thread machine will have a top loop, a bottom loop and single needle thread, whereas, a four thread machine will have 2 needle threads, a bottom loop and a top loop. So, if you need to know more about your machine and make sure that you switch off the machine before threading.
2. Start sewing
You can make use of the foot pedal to adjust the speed of sewing. The foot movements will help the fabric to slide correctly throughout the sewing area. The cutting width is another factor that should be taken note of because here we decide how much fabric it want to keep inside the seam. If you want more fabric within the hem or seam, you need to adjust the cutting width. For example, if you wish to make a rolled hem with a thick cloth then you need to increase the cutting width to a higher level.
3. Know your differential feed system
A differential feed system has 2 feed dogs, the front feed and the back feed dogs. The front feed is to push the cloth under the presser foot whereas; the back feed is used to push out the cloth out of the machine. You need to increase the differential feed in order to ease something into a hem of a dress. When working on a lightweight cloth, you have to decrease the level of differential feed.
4. Adjust the thread tension
Thread tension adjustment is the toughest job of using an overlock sewing machine for many. There are some recommended settings already in the machine and beginners can start sewing with that. If that doesn’t give desired results, you can thread your machine with a different color thread so that you will not face any problem in identifying thread that is creating problem. After identifying the problem causing thread, you can tweak the tension slightly and test again. If the fabric is wrinkled up, you need to lower the thread tension, and if it is loose, you have to increase the tension. Continue until you achieve the desired stitch quality.
Once you become familiar with the basic techniques of an overlock sewing machine, you can have fun with the machine by experimenting further and become a professional overlock sewing machine user.
