JACK Z7
Digital heavy-duty machine with triple feed
Brand: JACK
A digital lockstitch machine with a triple-transport system in which the feed dog, needle, and presser foot move together, for sewing the heaviest materials such as automotive (steering wheels, seats), sofas, bags, and mattresses (translated from the Italian text).


Features
- Triple feed — feed dog, needle, and presser foot, with special design, feed even the heaviest materials evenly.
- The artificial intelligence chip instantly relays thickness and resistance changes to the motor, increasing piercing power.
- When the thickness sensor detects material thickness, it automatically activates the second presser foot and additional thread tension.
- Dual variable presser foot — two adjustment buttons activate automatically or manually according to overlap or thickness.
