} } Smooth and capable 3 and 4-thread overlocker Janome MyLock 454D Sailing Line Create secure stretch seams, professionally finished garment interiors and beautifully overlocked fabric edges with a compact machine engineered for smoother feeding and quieter operation. The Janome MyLock 454D combines an eight-piece feed system, easy lower-looper threading, differential feed and an improved Sailing Line presser foot. 3 / 4 thread configurations 1,300 SPM maximum sewing speed 8-piece feed dog system 6.1kg machine weight View Instruction Manual Download Product Brochure Janome’s Sailing Line combines improved feeding, stability and user-friendly conventional threading. 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. New Zealand and Australian package Supplied with the essential tools to begin The regional package includes the standard snap-on presser foot, Janome HAx1SP needles, tweezers, large and small screwdrivers, instruction book and foot controller with power lead. Standard snap-on overlocking foot HAx1SP #11 needles × 2 HAx1SP #14 needles × 3 Large screwdriver Small screwdriver Tweezers Foot controller Power lead Instruction book Built-in carry handle The waste chip box, soft machine cover, additional specialist feet and extra-wide table are optional accessories. 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. The enhanced foot improves visibility, rolled-hem guidance and movement across thicker seams. 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. Follow the complete threading sequence without relying on memory. 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. Specialised rubber feet help keep the machine stable on the sewing table. 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. Available overlocking techniques Professional finishes for garments and creative sewing Four-thread overlock 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 Combine differential feed, stitch length and tension to create controlled gathers. Lettuce-leaf edging Stretch knit fabric during rolled hemming to create a decorative wave. Who is the MyLock 454D for?
