JACK Overlock C4

A series of high-performance 3-, 4- and 5-thread overlocks, equipped with an integrated energy-saving motor mounted in the head directly on the machine’s main shaft (DIRECT DRIVE system), which guarantees quiet and reliable operation and lower power consumption. 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. The world’s first industrial overlock with a built-in operation panel with voice functions and a Reset button to restore factory settings.
