An automatic industrial JACK lockstitch machine for sewing thin, medium and heavier fabrics. It has automatic thread trimming, automatic presser foot lifting and programmable backtacking.
The JACK A4C-C is a new-generation machine with an updated design. It is versatile: suitable for work from the thinnest fabrics to heavier items. The maximum stitch length is 5 mm.
A 550 W servo motor is integrated into the machine head. It drives the shaft directly, without a belt drive, so the machine does not vibrate, runs quietly and starts only when the pedal is pressed. Compared with clutch motors, the machine starts sewing smoothly, without a jerk, which makes it easier to control when sewing complex parts, and it uses up to 80 % less electricity. Thanks to its quiet operation, it is also suitable for homes or rooms where noise level matters.
The needle can be set to stop in the up or down position, and the sewing speed is adjustable. The machine has an improved lubrication system, and its surface is powder-coated, so it is resistant to abrasion and keeps its appearance for a long time.
