4-Thread Overlock
Your baby lock enspire comes to you set for 4-thread serging, which provides a very durable, yet
fully stretchable, seam or edge finish on all kinds of fabrics. With tensions properly set, 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 tbe top side of the stitch, interlocks with both loopers to add
durability. The upper looper thread, that resembles a zig zag, on the upper side of the fabric, is
from the upper looper that moves up above the throat plate and down. The lower looper thread,
that resembles a zig zag on the lower side of the fabric, is from the lower looper that only moves
lower than the throat plate.
The tension on each thread is controlled by its own tension dial. Turn the dial to a higher number
to tighten or increase the tension; turn it to a lower number to loosen or decrease tension. The
chart on the inside back cover indicates the suggested number ranges for 4-thread stitching. On
this chart, record specific settings for your own machine.
Various threads and individual preferences may require shight adjustment to the needle thread
tension as well. Always sew a test sample to determine if the desired result is achieved. Refer to
the diagrams for tension guidlines.
