5.7 Ruffling support
There are 3 additional setting options to support ruffling:
• Adjusting the needle thread tension
• Adjusting the hook thread tension
• Adjusting the tape tension
This ruffling support defines the ruffling value from which the
needle/hook thread tension will increase with the ruffling value.
The graphic below shows the preset increase of the needle/hook
thread tension (Y axis) with the rising ruffling value (X axis):
Fig. 73: Ruffling support
In this example, the needle/hook thread tension remains constant
up to a ruffling value of 4 and increases linearly starting with
the initial ruffling value of 4 before remaining constant from the
maximum ruffling value of 12.
The factory setting of the machine defines that the initial needle/
hook thread tension amounts to 40% and will increase by another
40% starting with the initial ruffling value.
Consequently, the needle/hook thread tension has been set up at
the factory in such a way that it amounts to a total of 80% starting
with the maximum ruffling value.
The needle/hook thread tension cannot exceed the maximum
of 100%.
