Meta Description: An overedger, also known as an overlock sewing machine or serger, is used for overlock stitching and seam finishing. Learn about its functions, uses, and advantages.
What is an Overedger?
An overedger, also called an overlock sewing machine or serger, is a specialized sewing machine that trims, sews, and overlocks fabric edges in a single step. It is primarily used in seam finishing, fabric reinforcement, and stretch fabric construction.
Overedgers prevent fabric edges from fraying or unraveling, making them essential for professional, high-quality garment production.

β Trims & Sews Fabric Edges β Cuts excess fabric while stitching for a clean finish.
β Prevents Fraying & Unraveling β Common in knitwear, activewear, and mass production.
β Can Handle Stretch Fabrics β Ideal for jersey, spandex, and other flexible materials.
β Works with 3, 4, or 5 Threads β Offers different stitch types for various applications.

Types of Overedger (Serger) Stitches
1. 3-Thread Overlock Stitch
- Used for lightweight fabrics and basic seam finishing.
- Provides some elasticity but is not the strongest stitch.
2. 4-Thread Overlock Stitch
- Ideal for seaming and edge finishing in stretch fabrics.
- Adds extra durability for garments that require strength and flexibility.
3. 5-Thread Overlock Stitch
- Combines a straight seam with an overlock edge, making it stronger for woven fabrics.
- Commonly used in industrial garment production.
4. Rolled Hem (Narrow Overlock Stitch)
- Used for delicate fabrics like chiffon, silk, and organza.
- Creates a fine, professional hem without bulky edges.
π‘ Tip: A 4-thread overlock stitch is the most versatile for general garment construction.
