A new model with a direct-drive servomotor has been introduced as an addition to the Juki MF-3620 Series of JUKI sewing machines. The new machine consumes only about half the power of the conventional models.(compared with the model equipped with the clutch motor)

A mounting base for the direct-drive type machine head is provided as standard with a hand pulley.

We are delighted to announce that new subclass models have been added; one model is best-suited to the sewing of hard-to-sew materials with multidirectional elasticity such as swimwear, while another model is for the prevention of uneven feed of the tape-attached parts of boxer briefs and running shirts to provide more consistent seam quality. In addition, the multipurpose type subclass model which is able to perform both one-side cutting and both-sides cutting has also been added, intended for sewing plants engaged in the sewing of diversified sewing items.

JUKI’s original design 4-needle flat seamer has been launched.
The Juki MF-3620 Series is provided with various functions for easier use and an increased sense of safety to achieve beautifully finished seams with consistency. The sewing machine prevents oil leakage. As a result, stain removal work is no longer required to allow the sewing machine to maintain increased productivity.

A direct-drive type model has been added.
A servomotor is installed on the machine head for adopting the direct-drive mechanism. The power consumption has been reduced by approximately 52 % as compared with the conventional model.

Since the Juki MF-3620 Series provides superb responsiveness, the material can be controlled as desired when sewing a curve part. In addition, the belt-drive type sewing machine (when a servomotor is used) has also had its power consumption reduced by 32 %.

Oil leakage is prevented.
The frame is shielded and equipped with mechanisms for micro-quantity lubrication and JUKI’s unique forced oil circulation.The thread take-up mechanism arranged on the outside of the arm prevents the entry of oil splashes and dust.

The MF-3620 is also configured with JUKI’s unique oil-thrower mechanism to protect the looper section from oil infiltration. Excess oil is speedily reclaimed via the new oil groove.
