mtc micro thread control
By default mtc micro thread control is always set to position
«0». The mtc micro thread control affects the amount of
looper threads around the fabric edge and can be adjusted
continuously during sewing.
> To enlarge the loops of the thread at the fabric edge,
turn the mtc micro thread control clockwise (+).
> To minimize the loops of the thread at the fabric edge,
turn the mtc micro thread control counterclockwise (-).
Setting the Differential feed
Gathering
Gather to fit
The two feed dogs can be geared to each other so that the
fabric is fed evenly while sewing and that neither wavering
nor unintended gathering occurs.
The differential feed is variable while sewing.
To prevent waving increase differential
feed to a value between 1 and 2.
To gather intentionally, increase differen-
tial feed to a value between 1.5 and 2.
An elongated stitch length enhances the
gathering effect.
Stretching
Default value
To prevent seam puckering, reduce dif-
ferential feed to a value between 0.7 and
1.
The differential feed in default setting 1
for flat and even seams.
