JACK 58450J and 58750J industrial universal high-speed twin-needle lockstitch fully automated sewing machines with integrated new-generation economical servo motors, horizontal hooks, needle feed and a needle disengagement system. The JK-58750J version comes with large horizontal hooks and a stitch length of up to 7 mm. This configuration is designed for sewing medium and heavy fabrics. The machine is indispensable for sewing parallel seams (bed linen, workwear, jeans, etc.). Disengaging either needle with a convenient lever makes work much easier when you need to turn a right-angle corner while sewing.
Synchronised operation of the needle mechanism and the feed dogs prevents fabric layers from shifting when sewing long seams. The fully automated sewing machine trims the thread automatically at the end of the operation and has automatic presser foot lifting, fully programmable backtacking and needle positioning. Supplied with a table and an integrated new-generation servo motor. The machine is very reliable, has an improved lubrication system and very high build quality. Thanks to its excellent specifications and engineering, the machine can be used very widely in any area of sewing.
2. Enlarged work area.
4. Extended feed dog adjustment range.
5. New hook adjustment system – much more reliable and simpler.
6. Hook protection.
A system of special sealed covers protects the hooks from contamination, improving and extending their service life without additional special maintenance.
7. New-generation machine lubrication system.
The central lubrication system of the machine is sealed. The oil is no longer contaminated by fabric dust and keeps its lubricating properties for a very long time. This extends the service life of the oil, and the fabrics you sew always stay clean and tidy.
8. Bearings instead of bushings.
The old-generation bushings in these machines have been replaced with bearings. This extends the machine's working life several times by avoiding bushing wear.
9. New-generation thread take-up system.
New fully adjustable thread take-ups. The adjustment range lets you readjust the machine to the fabrics being sewn, from thin to thick.
10. Presser foot system that adapts to fabric thickness.
Thanks to a special floating system, the presser foot automatically adapts to the thickness of the fabrics being sewn.
11. Graduated presser foot pressure adjuster and improved stitch density adjustment system.
12. New-generation thread trimming solenoid design – greater reliability, less frequent maintenance.
13. Special steel shaft design – low vibration and stable machine operation.
14. Special reinforced belt transmission.
Belt transmission – less noise, less vibration, more stable and cleaner machine operation.
15. Needle disengagement system.
The needles can be disengaged with a single press of a lever. Very convenient when you need to turn right-angle corners while sewing.
