Main Features & Creative Benefits

Beautiful Overlock Seams for Dynamic Fabrics

Achieve uniform and professional stitch results even if you are new to serging. Offering 15 distinct overlock stitch variations across 2, 3, or 4 threads, the Bernette Funlock 44 provides ultimate flexibility to finish every fabric category. Effortlessly design resilient mock-flatlock seams, secure 4-thread construction stitches, and beautiful, tidy rolled hems with widths up to 1.5 mm.

Color-Coded Threading Made Exceptionally Simple

Banish serger-threading anxieties forever. The B44 utilizes a brightly detailed, open color-coded thread path that maps routing paths step-by-step. Guided color markings, a built-in lower looper threading mechanism, and a separate helper needle threader ensure effortless setup, so you can transition between thread configurations in minutes.

Convenient, Integrated On-Board Storage

Keep your essential accessories consolidated and at hand. The B44 stores your frequently used tools—such as tweezers, lint brushes, and needle threaders—directly inside the looper cover. A specialized accessory case handles all additional standard equipment, ensuring a streamlined workspace that keeps your creative workflow flowing.

Precise, High-Speed Performance with Clean Waste Disposal

Maintain impeccable stitch quality even when powering ahead at speeds up to 1,300 stitches per minute. With its heavy-duty mechanical build, this overlocker handles heavy wools, thick denim, and multi-layered projects without slowing down. The included clip-on cut-offs waste bin directly catches stray fabric trimmings as they are cleanly sliced by the bottom knife drive, keeping your studio spotless.

Infinitely Adjustable Differential Feed

Eliminate puckered seams on fine silks and stretched-out wavy edges on highly elastic activewear. The built-in differential feed is infinitely adjustable between 0.6 and 2.0 while you sew, guaranteeing lay-flat seams on any material. Additionally, you can deliberately set the differential feed to create puckered, decorative lettuce-edges and delightful ruffles.
