Juki AMS-221F-HS3020SZ5000PSF (300x200) Pattern Sewer

Shorter thread remaining function *

Since the counter knife position has been changed, length of needle thread and bobbin thread remaining on the material after thread trimming is reduced to 5 mm or less. As a result, securing of thread at the end of sewing is no longer required.
* The bird's nest reduction function and shorter-thread remaining function cannot be used simultaneously.

Newly-developed active tension

Highly-evaluated active tension that is used for setting the needle thread tension is now added with new functions. The output can be changed over with the memory switch between the low-tension side output and the high-tension side output to enable fine adjustment of the thread tension in the actual area of use. Not only the thread tension during sewing can be changed at a pin point but also it can be set in accordance with the material thickness. In addition, the needle thread tension that is likely to vary with the sewing direction can also be corrected. All of these adjustments can be done on a stitch-by-stitch basis through the operation panel with ease. Since the needle thread tensions adjusted in accordance with various sewing conditions are reproducible, setup changing time is reduced at the time of changeover of processes.

Intermediate presser

Height of the lower dead point of intermediate presser can be changed steplessly in order to respond to sewing of multi-layered sections of material. (Standard: 0 - 3.5 mm; Maximum: 0 - 7.0 mm)
The intermediate presser stably holds the sewing material, thereby preventing sewing troubles such as stitch skipping and thread breakage. In addition, the intermediate presser can be held at a desired height according to the material thickness, thereby preventing the sewing product from being damaged. Since the intermediate presser lifting amount is increased from the conventional 20 mm to 25 mm, ease of placement of the material on the sewing machine is increased.
