JUKI MF-7500 Series Specifications page 2

The MF-7500 Series is
a newly developed coverstitch machine
provided with lots of mechanisms
for improving the seam quality.
It is provided with many different sewing-related mechanisms which contribute to
improved seam quality, such as the new feed mechanism, and differential-feed
micro-adjustment mechanism. In addition, the machine is provided as standard with
a looper thread twining prevention mechanism for improved maintenance.
Seam quality is improved!!
Thanks to the new feed mechanism,
many different types of sewing are achieved.
The feed locus can be adjusted externally. The feed locus is now
adjustable in terms of the vertical direction and horizontal direction,
thereby improving responsiveness to sewing materials.
The
world's
first
Differential-feed micro-adjustment mechanism
It is possible to finely adjust the differential feed amount to a best-suited
value for the material to be used. The differential feed ratio is constant
even if the stitch length is changed.

The longitudinal position of the
feed is adjustable. As a result,

puckering that are likely to occur
when sewing products made of
e l a s t i c m a t e r i a l s s u c h a s
foundations are reduced. This
means that the machine promises
improved responsiveness to
elastic materials.
Elas tic material or delicate
material can be sewn with the
presser foot kept slightly raised.
This effectively helps reduce the
degree of slippage, warpage and
damage of the material.
