Jack A4F-D, A4F-H sewing machine

Automatic 1-needle lockstitch machine with an electronic transport system, equipped with an energy-saving servo motor, mounted directly on the main shaft of the machine (Direct Drive), which guarantees quiet and reliable operation and reduces electricity consumption. The machine is equipped with an electronic transport system (tine movement programming system) controlled by stepper motors. In addition, the machine has a stepper motor that controls the stitch length setting in the machine and is responsible for the locking function. This solution significantly reduces the noise level during locking and also allows you to precisely set the stitch length with an accuracy of 0.1 mm.
