Ⓓ is pressed on the AW setting screen, the thread
When
unraveling strength setting screen is displayed.
Thread unraveling strength can be set in five different stages as 1
to 5 on the thread unraveling strength setting screen. If "0" is en-
tered for the thread unraveling strength, thread unraveling will not
be carried out.
In the case the thread is stiffened with resin such as the bond
thread (coating thread), it is not possible to wind the thread on a
bobbin. In such a case, enable the thread loosener to allow it to
loosen the thread end.
The thread loosener operates to loosen the thread end. Its refer-
ence set value is "1". The larger the set value becomes, the more
times the thread loosener operates in repetition according to the
set value.
1. Thread loosening operation takes time. It is recom-
mended to minimize the set value as long as the
thread can be wound on a bobbin. The larger the
set value becomes, the longer time is required for
bobbin winding. In such a case, sewing cannot be
started until the bobbin replacement is completed.
2. Do not enable the thread loosener when using any
thread other than the bond thread (coating thread). If
the thread loosener is enabled when using any other
thread, the thread will be fluffed and will be caught in
the bobbin. In such a case, the thread remaining in
the bobbin cannot be completely removed.
When you press Ⓔ on the AW setting screen, the bobbin thread
end length adjustment screen is displayed.
On the bobbin thread end length adjustment screen, the bobbin
thread end length can be set from -100 to 0. If you input 0 (zero),
the thread end length adjustment will not be carried out. In this
case, the thread end length will remain as is cut by the AW device.
