MO-6900S 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 8,000 to 8,500rpm. To offer improved sewing
capabilities as well as to prevent stitching misshapes, the machine
is equipped as standard with the needle thread heat remover and
needle cooler.
