Product Information
BERNINA
L 450 Overlocker
The BERNINA L 450 Overlocker offers exceptional ease of use, speed, and precision for beginners and experienced sewists alike. Perfect as a companion to any sewing machine, it cuts, sews, and finishes seams in one single operation with flawless 2-, 3-, or 4-thread stitch formations.
Max Sewing Speed
Smooth AC motor for reliable, even stitching.
Variations
Overlock, stretch, flatlock, rolled hem, and picot.
Cutting Width
Clean edges on everything from sheers to heavy fabrics.
Drive Technology
Reliable power with 5-step presser foot pressure.
Easy Threading
Color-Coded Lay-In Threading
Follow the color-coded lay-in threading paths, with a lower looper assistant to help guide the way and a handwheel position window that shows exactly when you’re ready to thread. A manual needle threader makes the needles just as easy.
Stitch Variety
16 Stitches & Built-in Rolled Hem
Choose from 16 stitch formations, including 4-thread overlock, 3-thread stretch, flatlock, rolled hem, and picot. The built-in rolled hem lever switches to rolled hemming without changing stitch plates, and you can adjust stitch length (0.8–4 mm) on the fly.
Precision Finishing
Micro Thread Control (mtc)
BERNINA’s patented Micro Thread Control lever fine-tunes the over-edge loops and eliminates loose loops instantly, so every seam finishes clean and balanced.
Feed & Performance
Differential Feed & Smooth AC Motor
Differential feed ensures wave-free seams in knits and pucker-free finishes on delicate fabrics. The smooth AC motor sews up to 1,200 stitches per minute, with 5-step presser foot pressure adjustment to match every fabric.
Organized Sewing
Smart Storage Built In
Frequently used tools are organized right inside the looper cover, so they’re always within reach. The dual-purpose cut-offs bin catches fabric trimmings and doubles as convenient storage for the foot control.
