Seam quality
- A newly-developed encoder-controlled stepping motor system has been adopted for the X-Y feed mechanism.

With this new system, the feeding frame position can be observed during sewing. As a result, the accuracy of the feed is remarkably improved to produce higher quality seams with increased accuracy while preventing deformations of the sewing shape.

- With JUKI's unique active tension, which has been well received in the market, and the programmable intermediate presser height control, the sewing machine flexibly responds to various materials to provide higher seam quality, and ultimately promising higher seam quality.

Active tension
- The needle thread tension is adjustable on a stitch-by-stitch basis during sewing. As a result, setting of the needle thread tension corresponding to the material thickness and correction of thread tension, which differs in accordance with the direction of sewing, can be easily carried out by inputting data on the operation panel. Since the needle thread tension is reproducible under a broad range of sewing conditions, the time required for setup changing at the time of process changeovers can be reduced.

Programmable intermediate presser
The lowest dead point height of the intermediate presser can be changed steplessly (Standard: 0 to 3.5 mm; Max.: 0 to 7 mm)during sewing. As a result, the intermediate presser securely holds even that material which has multi-layered sections to prevent the material from flopping, thereby preventing sewing troubles such as stitch skipping and thread breakage.

- In addition, damage to the sewing material is prevented by keeping the appropriate intermediate presser height according to the material thickness. (The stroke of the intermediate presser is adjustable in the range from 0 mm to 10 mm.)

Semi-dry head
- The frame (needle bar and thread take-up lever section) is lubricated with grease and the hook is lubricated with a minute quantity of oil from the oil reservoir. This lubricating system reduces oil stains on apparel products. With our advanced dry-head technology, which has already been adopted for many JUKI sewing machine models, the AMS-221EN Series protects customer products against oil stains.
