Advantages of Overlock Sewing Machine
Professional finish
It makes your homemade items look like they came from a store. The inside seams are neat and tidy, a hallmark of professional finish sewing.
Speed and efficiency
Because it sews, trims, and finishes the edge all in one step, it’s a fast sewing machine. This saves a lot of time compared to doing these steps separately with a regular machine and scissors.
Strong and durable seams
The stitches created by an overlock are strong yet flexible. This makes them great for items that will get a lot of wear or need to stretch.
Stops fraying completely
By wrapping the fabric edge in thread, it completely stops fabric fraying. This helps your garments last longer and look better.
Types of Overlock Sewing Machine
Single-thread overlock machine: Single-thread overlock is a single-needle one-thread stitch, which is mainly used to sew the edge of the blanket.
Double-thread overlock machine: Double-thread overlock is a single-needle double-thread stitch, which is mainly used to sew parts with high elasticity, such as the bottom edge of a stretch shirt.
Three-thread overlock machine: Three-thread overlock is a single-needle three-thread stitch, which is a common stitch for ordinary knitted garments, especially the stitching of some low-grade garments.
Four-thread overlock machine: Four-thread overlock is a double-needle four-thread stitch. Compared with the three-thread overlock, one needle thread is added, and the strength is improved. It is used for sewing parts of higher-grade garments or is stretched more, and the friction is stronger.
Five-thread overlock machine: Five-thread overlock is a double-needle five-thread stitch, which further improves the stitch fastness and production efficiency, and has better elasticity than a four-thread overlock. It is often used in the sewing of outerwear and underwear.
It is a high-end electric overlock machine with a blue eco-friendly paint finish, featuring smooth and modern lines. Equipped with an efficient motor running at 2400 RPM, it delivers steady and powerful power output. The control panel is made of fingerprint-resistant material, and the electronic adjustment buttons have a sensitive feel.
An intelligent lubrication system is built-in, which can automatically detect and prompt for oiling maintenance. The extended worktable is made of wear-resistant composite materials, with rounded edges to ensure safety. The fabric feeding system uses precision steel gear transmission. It comes with dual safety protection devices that will automatically cut off power when the machine overheats or becomes overloaded.
550W energy-saving direct-drive motor cuts power consumption by over 30% compared with old belt-driven models, lowering factory electricity costs for long-term production.
Fully enclosed automatic lubrication system reduces noise and oil stains to avoid fabric contamination.
Modular head design allows quick replacement of presser feet, needle plates and knife holders, easy for new operators to maintain.
3-thread overlock: basic edging for lightweight fabrics and small home textile accessories.
4-thread overlock: universal garment model combining seaming and edging, standard for most clothing factories.
5-thread overlock: dual-chain stitch + overlock for high tensile seams, ideal for sportswear and underwear. Customization available for special stitch lengths, presser feet, extended sewing tables and dust suction devices.
Application of Overlock Sewing Machine
Seaming
Overlock machines are perfect for creating seams on knit fabrics and other stretchable materials.
01
Finishing
Overlock machines can be used to finish the raw edges of fabric, creating a professional-looking, clean, and neat finish.
02
Hemming
Overlock machines can be used to create a professional-looking hem on your garments and other items.
03
Gathering
Overlock machines can be used to gather fabric, which is a great way to create gathers in your garments or other items.
04
Decorative stitching
Overlock machines can also be used to create decorative stitches, like rolled hems and lettuce edges, which can give a beautiful finish to your projects.
05
Components of Overlock Sewing Machine
Needles: Overlock machines use one or two needles (some specialized ones use more). They are often a special type designed for sergers.
Loopers (upper and lower): As mentioned, these parts create the thread loops that wrap around the fabric edge. There’s an upper looper and a lower looper, and they work together instead of a bobbin.
Knives/blades (upper and lower): These are the cutting blades that trim the fabric edge neatly just before the needles stitch.
Presser foot: This foot holds the fabric down as you sew, similar to a regular sewing machine, but it’s specialized for overlocking.
Differential feed (very simple): This is a clever feature! Overlocks have two sets of “feed dogs” (the little teeth under the presser foot that move the fabric). The differential feed serger control allows these sets of feed dogs to move at different speeds. This helps prevent stretchy knit fabrics from stretching out or puckering as you sew. It can also be used to gently gather fabric.
Thread tension dials: You’ll see several dials, one for each thread. These control how tight or loose each thread is. Proper overlock tension settings are important for a balanced, neat stitch.

FAQ
|
Q: Is there a big difference between direct-drive overlock machines and old belt-driven versions? A: The difference is significant. Direct-drive models save over 30% power, run much quieter, and come with automatic thread trimming and automatic presser foot lifting to cut labor costs. They deliver far more stable performance during long-hour assembly line work. |
|
Q: What daily maintenance does an industrial overlock machine require? A: Clear thread scraps and lint from the knife holder daily, and apply special sewing machine oil regularly. Our machines adopt a fully enclosed automatic lubrication system, which greatly reduces maintenance frequency compared with old-fashioned models for simple upkeep. |
|
Q: Max fabric layers the machine can sew? A: Our industrial models handle 6–8 denim layers; stable for chiffon & lace with few part swaps. |
