bernette 44 Funlock
(b44)
Achieve clean, professional edge finishes and durable seam construction with the bernette 44 Funlock overlock serger! Designed for garment construction, decorative edging, and quick rolled hems, the b44 Funlock features 15 built-in stitch patterns supporting 2-, 3-, and 4-thread overlock configurations. Powered by a high-speed motor reaching up to 1,300 stitches per minute, this compact serger incorporates a precision differential feed system, color-coded lay-in threading paths, a lower looper threader, and an integrated rolled hem lever. Complete with bright LED workspace lighting, a large cut-off bin, and an upper looper converter for lightweight fabrics, the b44 Funlock makes serging simple and precise.
Offers durable 4-thread seam construction, clean 3-thread edge finishing, and 2-thread flatlocking or delicate rolled hems.
Visual color-guided pathways and lay-in tension disks simplify step-by-step setup from thread spool to looper needles.
Fine-tunes fabric movement via an adjustable dial ratio to eliminate puckering on knits or create controlled gathering and ruffling.
Delivers up to 1,300 stitches per minute for fast production while including an upper looper converter for lightweight 2-thread work.
Professional Stitch Range
15 Built-In 2-/3-/4-Thread Stitch Patterns
Deliver professional finishes across every garment project with 15 built-in stitch options. Choose a durable 4-thread overlock stitch for heavy seams, a 3-thread option for standard edge overcasting, or a 2-thread stitch for lightweight fabrics and decorative flatlocking.
Foolproof Threading
Color-Coded Lay-In Thread Pathways
Thread your serger confidently without guesswork. Color-coded thread routes guide each thread line from the spool to the needle and looper eyes, while lay-in tension disks ensure balanced thread tension during high-speed sewing.
Fabric Feed Control
Precision Differential Feed System
Control how fabric moves beneath the presser foot using the differential feed dial. Adjusting the ratio prevents stretched out or wavy seams on knits and eliminates puckering on lightweight wovens while allowing for controlled gathering and ruffling.
Bright Workspace
Brightly Lit LED Work Area
Illuminate the needle bar, presser foot, and trimming knife zone clearly. Targeted LED lighting floods the 3.43-inch work area, reducing eye strain and providing high-contrast visibility when working with dark or textured materials.
Seam Precision
Adjustable Stitch Length Dial Control
Fine-tune seam density and strength using an exterior stitch length dial. Select shorter stitch lengths for dense and secure seam construction or longer lengths for decorative finishing and flexible knit seams.
Custom Seam Width
Precision Cutting Width Adjustment Dial
Determine exactly how much fabric is trimmed as you sew. Adjusting the cutting width dial matches seam margins (3mm to 7mm) to fabric weight, creating flat, bulk-free edges on fine or thick materials.
Instant Rolled Hem
Integrated Rolled Hem Selection Lever
Switch from standard overlock seaming to a narrow 1.5mm rolled hem instantly without changing needle plates or attaching extra accessories. Simply slide the built-in lever to roll delicate edges cleanly on chiffon, organza, and scarves.
2-Thread Versatility
Upper Looper Converter for 2-Thread Serging
Convert your serger for delicate 2-thread overlocking using the included upper looper converter attachment. Engaging the converter redirects the upper thread path, using less thread and producing a flat, un-bulky finish on sheer fabrics.
Production Speed
High-Speed 1,300 Stitches Per Minute Performance
Power through long seams and production runs in record time. Delivering up to 1,300 stitches per minute, the b44 Funlock maintains consistent stitch formation and smooth fabric feeding even at maximum speeds.
Clean Workspace
Dual-Zone Accessory Storage & Cut-Off Bin
Keep your essential tools organized and your work surface clear. Frequently used tools store directly inside the front looper cover, while an included large cut-off bin clips onto the machine base to catch fabric trimmings as you sew.
