One needle lockstitch machine with double transport, direct drive servo motor built in the head and full automatic. It is designed for sewing heavy materials (e.g. jeans) and so-called “Difficult” layers exposed to moving during sewing. Automatic functions (thread cutting, bartacking at the beginning and end of sewing, needle positioning, presser foot lifting) are programmed using a readable and easy to use control panel located in the machine head. Direct drive motor reduces vibration, provide quieter work and reduces the cost of exploitation a lockstitch machine.
