Sewing
ActivStitch™ Technology
1. Thread tension
2. Thread metering
The ActivStitch™ technology feature has two ways to
control the needle thread: thread metering and thread
tension. To get the best sewing result it will
automatically use thread metering when possible.
Thread metering automatically and continuously
measures the fabric thickness to meter the correct
amount of thread for the selected stitch.
When thread tension is used, the tension discs will keep
the correct amount of tension on the upper thread. Some
special techniques may require the use of thread tension.
Deselect the ActivStitch™ technology feature in
Temporary Settings to ensure that thread tension is
engaged. When the ActivStitch™ technology feature is
selected the control visible in Sewing Mode will change
between thread metering and thread tension depending
on the current settings and the loaded stitch.
Use the thread metering/thread tension control to
adjust the balance between needle thread and bobbin
thread, e.g. decrease when using metallic thread and
increase when using heavy weight thread. Make a few
tests with different settings on a scrap piece of the fabric
you are going to use and check the balance between the
upper thread and the bobbin thread.
Note: When changing the value of the thread metering/thread
tension setting, the changes only affect the selected stitch.
Your changed settings will be reset to default when selecting
another stitch.
Tip: Increase the thread metering/thread tension setting for
best results when sewing on denim fabric with thick threads.
Adjust Thread Tension/Thread Metering
Correct tension
For the best stitch appearance and durability make sure
the threads meet evenly between the two fabric layers.
Tension too tight
If the bobbin thread is visible on the top side of the
fabric, the thread tension/thread metering is too tight.
Reduce the thread tension/thread metering.
Tension too loose
If the upper thread is visible on the underside of the
fabric, the thread tension/thread metering is too loose.
Increase the thread tension/thread metering.
For decorative stitches and buttonholes the upper
thread should be visible on the underside of the fabric.
Make a few tests on a scrap piece of the fabric you are
going to use and check the tension.
