Professional finishing made approachable

A practical overlocker for garments, knits and alterations

The MyLock 454D is an excellent choice for sewists ready to replace slow zigzag edge finishing with faster, cleaner and more professional overlocking.

It trims the raw fabric edge while wrapping it securely in thread. Four-thread overlocking can sew and finish stretch seams in one operation, while three-thread configurations are ideal for neatening woven seams, decorative finishing, rolled hems and flatlock effects.

The machine uses straightforward colour-coded threading, slide-in tension guides and an accessible lower-looper mechanism. It is conventionally threaded rather than air threaded, keeping the operation familiar and mechanically uncomplicated.

Why the MyLock 454D stands out

Enhanced fabric handling with easy-to-understand controls

01

Eight-piece feed system

Multiple feed sections maintain broad contact with fine fabric, stretch knits and layered seams.

02

Easy lower-looper threading

The most difficult threading route is brought into a more accessible position.

03

Three and four-thread sewing

Construct stretch seams, finish woven edges, create rolled hems and form flatlock effects.

04

Differential feed

Adjust fabric movement from 0.5 to 2.25 to manage waving, puckering and gathering.

05

Improved presser foot

A wider tip, underside grooves and a stopper support rolled hems and bulky seam crossings.

06

Lay-in tension guides

Slide each thread into its tension path while the presser foot is raised.

07

Quick rolled-hem conversion

Change the chaining-finger position without replacing the needle plate.

08

Reduced vibration

Special Hanenite rubber feet help deliver quieter and more stable high-speed sewing.

Enhanced Sailing Line feeding

Eight feed-dog sections improve control

The feed dogs maintain contact with the project before, beneath and behind the needle area.

This helps fine woven fabrics, jersey, fleece and layered seams move consistently beneath the foot.

Additional feeding support is especially valuable when the presser foot climbs over a crossed seam or changes between fabric thicknesses.

Improved presser-foot engineering

Smoother starts and better bi-level sewing

The foot has a gently curved leading edge that helps it approach thicker fabric levels smoothly.

Grooves beneath the foot help reduce fabric slippage, while the built-in stopper limits excessive tilting when the machine crosses bulky seam intersections.

An extended needle-drop guide improves visibility when positioning the fabric before it reaches the knife and needles.

  • Wide rolled-hem tip
  • Gentle leading curve
  • Anti-slip underside grooves
  • Foot-tilt stopper
  • Extended needle-position guide
  • Snap-on attachment
Clear conventional threading

Slide-in tension guides and colour-coded paths

The MyLock 454D is conventionally threaded, with each route clearly organised and identified.

Raise the presser foot to release the tension discs, then slide each thread into its corresponding guide. This helps ensure the thread is seated correctly inside the tension system.

Separate colours identify the left needle, right needle, upper looper and lower looper. The full sequence is also displayed inside the opening front cover.

Lay-in tension

Slide thread directly into each tension guide.

Tension release

Raising the presser foot releases all four tension paths.

Colour coding

Each needle and looper route has its own colour.

Visible diagram

The threading chart remains visible while the cover is open.

The difficult path made easier

Accessible lower-looper threading

Open the looper and side covers, then follow the green colour-coded route to the lower-looper mechanism.

Janome’s easy-threading system brings the difficult guide into a more convenient position, reducing the need to reach behind the upper-looper assembly.

This is not an air-threading system, but it makes conventional lower-looper threading considerably more approachable.

Threading guidance built into the machine

A full diagram inside the front cover

The printed chart shows each thread route in the correct order and identifies every internal guide point.

Keeping the chart inside the machine means it remains available whenever threads are changed or the overlocker needs to be rethreaded.

Control stretching, puckering and gathering

Differential feed from 0.5 to 2.25

Differential feed changes the relationship between the front and rear feed dogs.

Increase the setting to help prevent stretch fabrics from becoming wavy or to create controlled gathering. Reduce the setting to help manage puckering on lightweight woven materials or to create a deliberately stretched finish.

Stretch knits

Help prevent rippled T-shirt and activewear seams.

Fine woven fabrics

Adjust feeding to help reduce unwanted puckering.

Gathering

Create controlled fullness by increasing the feed ratio.

Lettuce edging

Stretch suitable knit fabric during rolled hemming.

Garment easing

Ease one fabric edge into another during construction.

Everyday overlocking

Return to the neutral setting for standard flat seams.

Quick rolled-hem conversion

Change techniques without replacing the plate

Move the chaining-finger switch knob from the standard position to the rolled-hem position.

With the stitch finger withdrawn, the looper threads can roll the fabric edge into a narrow, dense finish.

Rolled hems are ideal for napkins, scarves, ruffles, sheer fabrics and decorative garment edges.

Improved guides help each thread enter its tension path correctly.
Reliable thread placement

Improved slide-in pre-tension guides

Each thread passes through a top pre-tension guide before entering its main numbered tension dial.

The guide design helps keep thread seated in the correct route and reduces common threading errors that can lead to loose or unbalanced stitches.

Stable operation at higher speeds

Hanenite rubber feet reduce vibration and noise

Overlockers operate quickly and use both needles and cutting knives, which can create vibration through the work surface.

Special rubber feet help isolate this vibration, reduce machine movement and create a smoother, quieter sewing experience.

Improved motor torque also supports controlled seam starts and movement through layered fabric sections.

Adapt the stitch to the project

Adjustable stitch length, cutting width and foot pressure

Stitch length

Adjust from 1 to 4mm for dense edging or longer construction seams.

Cutting width

Adjust from approximately 3.1 to 7.3mm depending on needle position.

Foot pressure

Adapt fabric contact for fine, stretch and firmer materials.

Retractable knife

Disengage the upper knife when fabric trimming is not required.

Cutting width using the left needle is approximately 5.3 to 7.3mm. When the left needle is not used, the available range is approximately 3.1 to 5.1mm.

A strong and flexible construction seam for stretch garments and general overlocking.

Three-thread wide overlock

Use the left needle for wider edge finishing on medium and heavier materials.

Three-thread narrow overlock

Use the right needle for a narrower edge finish on light and medium fabrics.

Three-thread rolled hem

Create a narrow rolled finish for ruffles, scarves, napkins and delicate edges.

Flatlock effect

Adjust the tension to form a flat decorative or joining stitch.

Picot edging

Produce a delicate decorative edge on chiffon and other lightweight fabrics.

Gathered overlocking
