Janome MyLock 654D Sailing Line overlocker
Janome Sailing Line overlockers are engineered for improved stability, power and fabric-feeding performance.
Professional-looking seams made more approachable

A dependable overlocker for garments, knits and everyday finishing

The MyLock 654D is designed for sewists who want fast edge finishing, strong stretch seams and polished garment interiors without moving to an industrial overlocker.

Configure it for two, three or four-thread stitching to construct stretch garments, neaten woven seams, create lightweight edge finishes, sew rolled hems, produce flatlock effects and add decorative overlocking.

The machine arrives fully threaded with four cones of white overlocker thread, allowing you to test the factory threading and begin sewing shortly after unpacking.

Colour-coded guides, lay-in tension channels, an accessible lower-looper threader and a detailed chart inside the front cover simplify future thread changes.

Why the MyLock 654D stands out

Improved feeding, stability and everyday usability

01

Eight-piece feed dog

Additional feed sections maintain broad contact with fine fabrics, stretch materials and multiple layers.

02

Easy lower-looper threading

An accessible lower-looper threading mechanism reduces the most difficult part of conventional overlocker setup.

03

2, 3 and 4-thread sewing

Select strong construction seams, standard edge finishing, lightweight overcasting, rolled hems and flatlocking.

04

Differential feed

Adjust fabric movement from 0.5 to 2.25 to control stretching, puckering, easing and gathering.

05

Improved presser foot

A longer, gently curved foot supports thicker transitions, rolled hems and multiple fabric layers.

06

Metal base plate

The stamped metal underside adds weight and rigidity for a more planted sewing experience.

07

Anti-vibration rubber feet

Special rubber feet help reduce vibration, movement and operating noise at higher speeds.

08

Quick rolled-hem conversion

Move the chaining-finger control without replacing the needle plate or fitting a separate component.

Enhanced Sailing Line feeding

Eight feed-dog sections improve control across the seam

The MyLock 654D doubles the number of feed-dog sections used on earlier models in this class.

The additional teeth maintain contact before, beneath and behind the needle area, supporting smoother movement through fine woven fabrics, jersey, fleece and layered garment sections.

The layout also improves bi-level sewing when the foot climbs from a normal seam onto a thicker crossed seam.

Enhanced presser-foot design on the Janome MyLock 654D
The redesigned foot improves rolled-hem guidance, visibility and movement over thicker seam intersections.
Better visibility and smoother transitions

An enhanced long presser-foot design

The front of the foot has a gentle curve that helps it approach thicker fabric levels smoothly rather than stopping abruptly at the seam.

Grooves beneath the foot help reduce fabric slippage, while an added stopper limits excessive tilting when the foot crosses a bulky intersection.

The extended needle-drop guide improves visibility and helps position the fabric edge accurately before it reaches the needle and knife.

  • Longer leading edge
  • Gentle front curve
  • Anti-slip grooves
  • Foot-tilt stopper
  • Needle-drop reference guide
  • Improved rolled-hem support
Clearer conventional threading

Lay-in tension guides and colour-coded threading paths

The MyLock 654D is not an air-threading machine, but Janome has made its conventional threading system as clear and accessible as possible.

Raise the presser foot to release the tension discs, then slide each thread into its numbered tension channel. The improved lay-in guides help prevent the thread from sitting outside the tension system.

The full threading chart is printed inside the opening looper cover, with separate colours identifying each needle and looper route.

Lay-in tension

Slide thread into each tension channel rather than pulling it through a narrow opening.

Automatic tension release

Raising the presser foot opens all four tension discs for easier threading.

Colour-coded routes

Follow individual colours for the left needle, right needle and both loopers.

Front-cover chart

The complete diagram remains visible while the looper area is open.

The hardest thread path made easier

Accessible lower-looper threading

Open the front and side covers to access the lower-looper mechanism and colour-coded guide points.

The lower-looper threading system moves the difficult guide into a more accessible position, reducing the need to reach deep behind the upper looper.

A handheld needle threader is also included for threading the overlocker needles.

Thread confidently without relying on memory

A colour-coded guide inside the front cover

Every threading path is displayed in sequence, including the left needle, right needle, upper looper and lower looper.

The diagram also illustrates standard overlocking and two-thread conversion settings, helping users confirm that the internal guides are positioned correctly.

Control stretching, puckering and gathering

Differential feed from 0.5 to 2.25

The differential-feed control changes how quickly the front and rear feed dogs move in relation to one another.

Increase the setting when stretch fabric becomes wavy or when controlled gathering is required. Reduce it when a fine woven fabric puckers or when a deliberately stretched effect is wanted.

The selected differential-feed and stitch-length settings are clearly visible through the side indicator windows.

  • Help prevent wavy knit seams
  • Reduce puckering on fine fabrics
  • Create controlled gathering
  • Ease one fabric edge into another
  • Create decorative lettuce edges
  • Return to neutral for standard sewing

The stitch-length and differential-feed settings can be checked at a glance.
Fast rolled-hem conversion

Move the chaining-finger control without changing the plate

Switch between ordinary overlocking and rolled hemming using the accessible chaining-finger control beside the needle plate.

Moving the finger out of the stitch formation allows the thread to roll the fabric edge into a narrow, dense finish.

No separate rolled-hem needle plate is required.

Lower-looper pre-tension slider on the Janome MyLock 654D
Move the slider between standard overlocking and rolled-hemming settings.
Faster stitch setup

Lower-looper pre-tension slider

The external slider changes the lower-looper thread path for standard overlocking or rolled-hemming techniques.

Move it to the standard position for ordinary seams, then select the rolled-hem position when directed by the stitch chart.

This reduces the amount of manual tension adjustment needed when changing between common finishes.

Trim only when the project requires it

Easily retractable upper knife

Turn the accessible release control to lower the upper knife when fabric trimming is not required.

Retracting the knife is useful for selected flatlocking, decorative techniques and situations where the edge has already been trimmed accurately.

The cutting width can also be adjusted to match fabric thickness, needle position and stitch formation.

Always keep the fabric edge clear of the stationary knife and needle area when sewing with the upper knife disengaged.

The upper-knife release is accessible from the open side of the machine.
Designed to feel planted at speed

Metal base construction and vibration-reducing rubber feet

High-speed overlocking can create vibration, particularly when the knife is trimming dense or layered fabric.

The MyLock 654D uses a stamped metal base cover to increase rigidity and stability beneath the machine.

Special anti-slip rubber feet help absorb vibration and reduce movement across the sewing surface.

Metal base plate

Adds weight and structural rigidity beneath the overlocker mechanism.

Anti-slip feet

Help the machine remain in place during faster sewing.

Reduced vibration

Supports smoother operation through ordinary and layered seams.

Lower operating noise

Rubber isolation helps limit vibration transferred into the sewing table.

Lighter finishes with less thread bulk

Two-thread overlocking with the supplied spreader

Fit the supplied spreader to the upper looper and use one needle together with the lower-looper thread.

Two-thread stitching creates a lighter, flatter finish than three or four-thread overlocking and reduces thread consumption.

  • Lightweight edge finishing
  • Delicate woven fabrics
  • Two-thread rolled hems
  • Decorative flatlocking
  • Reduced seam bulk
  • Lower thread consumption
Professional finishes for many projects

Important information before purchasing

The MyLock 654D is a conventional manually threaded overlocker. It does not have an air-threading system or automatic thread tension.

It does not create a coverstitch. A separate coverstitch machine is required for professional knit hems with parallel stitching on the top and looped coverage underneath.

The MyLock 654D does not have a free arm. It uses a broad flat overlocking bed designed to support consistent edge feeding.

It is a premium domestic overlocker intended for garment sewing, alterations and creative projects rather than continuous industrial production.
