Product Details
The Janome ML454D overlocker is a versatile sewing machine. It can do basic seam finishing and advanced techniques like rolled hemming and flatlocking. This 3/4 thread overlocker delivers professional results whilst remaining accessible to sewers at various skill levels.
The ML454D offers speed and precision, It works at up to 1,300 stitches per minute. It also gives smooth and consistent results on various fabric types.
Its better fabric feed system has an 8-piece feed dog design. This helps fabrics move smoothly under the presser foot. It reduces common problems like puckering and uneven stitching.
What sets this overlocker apart is its blend of user-friendly features and advanced capabilities. The ML454D has a colour-coded threading system and adjustable settings for different fabric weights. This machine gives experienced sewers the flexibility they need. Also, it is simple enough for beginners learning overlocking techniques.

3/4 Thread Overlocking and Seam Options
The ML454D is a flexible 3/4 thread overlocker that makes professional seam finishes. Users can pick between 3-thread or 4-thread setups based on their project needs.
The 4-thread overlocking gives the most durability for heavy-duty seams. This setup creates the strongest seam for garments that need extra support.
The 3-thread overlocking provides a lighter finish that works well for most general sewing tasks. This option uses fewer threads but still makes neat, secure seams.
You can adjust the cutting width from 3.1mm to 7.3mm based on the needle you use. Seams can be 5.3mm to 7.3mm wide when using the left needle. Without using the left needle, seams are narrower, from 3.1mm to 5.1mm.
You can change the stitch length from 1mm to 4mm for different types of fabric. The differential feed ratio works between 0.5mm and 2.25mm to stop fabric from stretching or puckering.

Rolled Hemming and Rolled Hem Conversion
Rolled hemming conversion requires simple setup changes on the ML454D. The upper knife releases with a gentle push operation for quick changeover.
The rolled hem feature creates narrow, professionally finished edges — perfect for finishing seams and curves in no time. This technique works exceptionally well on lightweight fabrics like chiffon, silk, and cotton lawn.
Rolled hem conversion involves adjusting thread tensions and changing the presser foot position. The machine's design makes this process straightforward without complex threading changes.
Fine rolled hems measure approximately 2–3mm in width. The consistent stitch formation prevents fabric fraying whilst creating an elegant finish.
The machine produces smooth rolled hems with minimal puckering. The refined feeding system ensures even fabric handling during the rolling process.

Ease of Use and User-Friendly Features
The Janome ML454D is a stable smooth sailing overlocker. It has colour-coded thread guides and a simple threading system for the lower looper. It also features snap-on presser feet and helpful instructional support.
The ML454D features a colour-coded threading system that simplifies setup by matching each thread path to the threading chart. This guides users through the correct sequence for needles and loopers, preventing common mistakes that affect stitch quality.
With clearly marked colours for the upper looper, lower looper, right needle, and left needle (in 4-thread mode), the system is easy to follow. Especially helpful for beginners, it also speeds up threading for experienced users.
The ML454D also features an easy threading lower looper mechanism that simplifies setup. Instead of threading through small openings by hand, you just put the thread in the colour-coded slot. The machine then guides it through automatically. This saves time and removes the frustration common with traditional overlockers.

Advanced Settings and Fabric Handling
The Janome ML454D gives you precise control over stitch formation. You can adjust the stitch length from 1mm to 4mm. This lets you pick shorter, denser stitches for lightweight fabrics and decorative finishes. You can also choose longer stitches for heavier fabrics, gathering techniques, and to use less thread.
The ML454D features a special 8-piece feed dog system with an adjustable differential feed ratio (0.5–2.25). This ensures even and steady stitching on materials like soft silks and stretchy knits, even with multiple layers.
The Lower settings Prevent puckering. Higher settings prevent distortion. A neutral 1.0 is ideal for most fabrics. It gives you consistent, professional-quality results every time.
