The JACK K5-UT-01GB is a new industrial CYLINDER-BED, fully automatic high-speed five-thread coverstitch machine for knits with top cover stitching, a new-generation economical integrated servo motor, needle positioning system and built-in LED work area lighting.
The JACK K5-UT comes with full automation – thread cutting and automatic presser foot lift functions.

The machine has a cylinder bed. The cylinder bed makes it much more convenient to sew sleeves and other narrow items. It is used mainly for sewing knit fabrics. The machine can sew several seam variants: three-needle five-thread with or without top cover, two-needle wide with or without top cover, two-needle narrow with or without top cover, and a straight chainstitch. The machine has a differential feed mechanism for adjusting the movement of the feed dogs and thus the fabric feed, to achieve the best possible sewing quality. The machine offers very high build quality, high productivity, very smooth and quiet operation, and no vibration even at high speed. An improved lubrication system, a modern new design and an exceptionally high-quality powder-coated finish extend the machine's service life for a long time.
Main advantages of the machine:
1. Very small cylinder bed diameter
The cylinder bed diameter is only 270 mm – very convenient for sewing both very small and large parts.

2. Very convenient stitch density adjustment
Simply slide the lever to set the desired stitch density.

3. Silicone lubrication system for the threads of all three needles

4. Control panel integrated into the machine head – convenient and quick machine control.

5. Special patented lower looper threading system
Threading the lower looper is very simple and quick.

6. Special needle guard
An adjustable special needle stabilising system – much nicer seams, with the needles protected from bending and breaking.

7. Differential feed adjuster
The fabric feed range is very easy to adjust for all sewing variants. By sliding the lever you can gather or additionally stretch the knit item you are sewing.

8. With additional parts, the cylinder bed can be enlarged to a standard-size bed
Thanks to the special narrow cylinder bed, you can conveniently and easily sew hard-to-reach areas such as sleeves, trouser hems, children's clothes and the like, and when needed you can fit additional parts in a few minutes to convert the narrow bed into a standard one. An incredibly versatile machine for all sewing variants.

9. New-generation servo motor (direct drive system)
Quiet operation, beltless drive, high speed, reduced vibration, soft start, quick stop, needle positioning and energy saving (up to 80%) – these are the advantages of new-generation servo motors compared with old-generation clutch motors.
