What is the difference between a coverstitch machine and an overlocker?

Before you know which one to choose, you need to understand what a coverstitch machine and a serger do. These two machines have very different roles in the sewing world, and confusing them can lead to an inappropriate purchase. Here's how they clearly differ.

What is an overlocker used for?

The overlocker is designed to join fabrics together while trimming excess material and creating a clean finish. It is ideal for stretchy or easily frayed fabrics. Widely used for clothing, it provides a professional and durable finish.

It uses 3 to 5 threads and 2 needles to create a very strong overlock stitch , often used for inside seams of clothing. It is fast, efficient and essential for anyone who wants to sew neatly.

• Layer, cut and overlock in one pass
• Essential for stretch fabrics and jerseys

What is a cover-covering machine used for?

The coverlock machine does not assemble fabrics. Its role is to create professional hems , particularly on t-shirts, leggings, or sportswear. It creates a visible cover stitch on the right side and loops on the wrong side.

It works with 2 to 3 needles and 3 to 4 threads, and allows you to sew elastic hems without ripples. The coverstitch machine is therefore perfect for finishing edges, but does not replace an overlocker .

• Specializing in flat and elastic hems
• Perfect finish on mesh, jersey, lycra

The main differences to remember

Here is a clear summary of the essential differences between these two machines:

Coverseal and overlock: are they complementary?

We often think that we have to choose between the two, but in reality, they are two machines with very different but perfectly complementary uses, especially in stretch or sports sewing.

Common points between the two machines

Although they don't do the same job, the overlocker and the coverstitch machine share several useful features to know.

• Fast machines designed for professional finishing
• Suitable for stretchy or delicate fabrics
• Requires precise threading and proper adjustments

Practical complementarities in sewing

In sewing, the ideal is to have two machines to benefit from a complete work chain: the overlocker allows for clean assembly, while the coverstitch machine finishes the garment with a soft and clean hem.

• The overlocker ensures the strength of the interior seams
• The coverer elegantly finishes the visible edges
• Together, they make it possible to produce professional clothing from A to Z.

Should you invest in a coverstitch machine or an overlocker?

Choosing between a coverstitch machine and an overlocker depends on your practice, your budget, and the types of fabrics you use. Each machine has its advantages, but they are not interchangeable. Here's how to help you decide.

For beginners in sewing

If you're new to sewing and want to improve your finishing, a serger is a good first investment. It allows you to quickly assemble pieces with a clean finish. A coverstitch machine can be added later, once you've mastered the basics.

• Priority to the overlocker for its versatility
• Easy to use after a short learning period

For regular or professional seamstresses

If you often sew jersey or lycra garments, having both machines is a definite plus. The coverstitch machine then becomes essential for achieving a flawless, stretchy hem.

• Double investment for a professional result
• Save time and improve quality on all finishes

Are there any combination machines?

Yes, some brands offer combined overlock/coverstitch machines (also called combi or 5-thread ). They are practical but often more complex to set up and less efficient than two separate machines.
