JACK Overlock JK-799S

A series of modern 4 and 5-thread overlocks with automatic thread trimmer. TheJACK Overlock JK-799S is equipped with an energy-saving Direct Drive motor built into the head, which significantly reduces noise, reduces vibrations and reduces energy consumption (up to 70% compared to traditional clutch motors). The modern design of the machine provides better ventilation of the motor, and thus faster and more efficient operation, and as a result, a longer machine life. Electromagnetic thread trimming is controlled by photocells and does not require connection of the machine to the compressed air system. The head has an integrated, work field illuminating LED diode. The machine is designed for light and medium sewing.

Technical parameters:

  • sewing speed: up to 5500 stitches / min
  • height of foot lifting: 5.5 mm
  • bottom differential feed
