Fig. 19: Fullness distribution controlled by the stepper motor (2)
(1) - Sewing head
The stepper motor for the differential bottom feed (3) is located under
the sewing table on the left side of the sewing head (1).
Controlled by the stepper motor, the fullness distribution can be programmed
and allows for a programmed retrieval of additional fullness in the top and bot-
tom layer of fabric.
The entire seam can be divided in up to 5 freely selectable seam sections.
Parameters can be set individually for each section. The activation of addi-
tional fullness always applies to the selected section to which you wish to add
fullness.
A distinction is made between:
• Differential bottom feed
• Differential top feed
You can select additional fullness "Fullness +" to incorporate additional
fullness in all 5 sections of the seam. "Fullness +" is used when fabric
is changed in the same program sequence, but with slightly more/less
fullness across all activated fullness sections of the seam.
