Kenmore 19110 - Computerized Sewing Machine - Thread Tension Balancing

Balancing Thread Tension
Correct tension
_i_ Needle thread (Top thread)
_2_ Bobbin thread (Bottom thread)
_3_ To loosen
_4_To tighten
The ideal straight stitch has threads locked between
two layers of fabric, as illustrated.
If you look at the top and bottom of a seam, notice
that there are no gaps. Each stitch is smooth and even.
When adjusting the needle thread tension, the higher
the number, the tighter the needle thread tension.
Results depend on:
- stiffness and thickness of the fabric
- number of fabric layers
- type of stitch

If the needle thread s rough on the wrong side
(Bottom side) of the fabric, and the stitch feels
bumpy, turn the dial to a higher tension setting
number to tighten the needle thread tension.
Adjusting the needle thread tension for a zigzag stitch
For an ideal zigzag stitch, the bobbin thread does not
show on the right side (Top side) of the fabric and
needle thread shows slightly on the wrong side
(Bottom side) of the fabric.
See the illustrations for correct appearance.
To match this appearance, adjust the needle tension.
Correct tension
_i_ Right side (Top side) of fabric
_2_Wrong side (Bottom side) of fabric
Minimize the amount of needle thread visible on the
wrong side (Bottom side) of the fabric without causing
excessive puckering, or causing the bobbin thread to
show on the right side (Top side) of the fabric.
Results vary with fabric, thread and sewing conditions.
Tension is too tight
_i_ Right side (Top side) of fabric

The corner of each zigzag pulls together on the right
side of the fabric,
