MO-6700S Series (September, 2003) 1/4
Since the machine comes with a needle-thread take-up mechanism
as well as a looper thread take-up mechanism, to offer upgraded
responsiveness from light- to heavy-weight materials with a lower
applied tension, it achieves well-tensed soft-feeling seams that
flexibly correspond to the elasticity of the material at the
maximum sewing speed of 7,000rpm.
The machine incorporates various mechanisms as standard, such
as a differential-feed micro-adjustment mechanism and an external
adjustment mechanism for adjusting the feed dog inclination as
well as increasing the differential feed ratio, which can be easily
adjusted to finish seams that perfectly match the material to be
used.
