4-Thread Overlock - Baby Lock Victory BLS3 Instruction And Reference Manual

4-Thread Overlock

With the Victory Thread Delivery System, the upper and lower looper threads lock together evenly
over the cut fabric edge(s) to form a flat, non-rolling pattern of overlocking stitches on both sides
of the fabric.
The left needle thread interlocks with both looper threads at the stitching line to create the seam.
The right needle thread, visible on the top side of the stitch, interlocks with both the loopers to
add durability. The upper looper thread, that resembles a zigzag on the upper side of the fabric,
is from the upper looper. The lower looper thread, that resembles a zigzag on the lower side of the
fabric, is from the lower looper.
Move the stitch selector lever to "A".
For the perfect 4-thread overlock stitch, follow the suggested settings and threading diagram
