The buttonhole is set on the machine itself and the machine repeats that hole, so there are no patterns to store and there is less on the machine to go wrong. Jack describes it as a mechanical buttonhole machine driven by an integrated single shaft motor, with an automatic thread trimmer and foot lifter controlled by a stepper motor. UAE uniform and shirt workshops use it for standard buttonholes on shirts, overalls and workwear, and for abaya and kandoora placket buttonholes on woven and knitted fabric.\u003c\/p\u003e\n\u003cp\u003eIf your styles change buttonhole patterns between runs, look at the electronic Jack JK-1790 instead.\u003c\/p\u003e\n\u003ch3\u003eWhat Jack publishes about this machine\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMechanical buttonhole head driven by an integrated single shaft motor.
