What the Jack JK-T781G catalogue covers

Two pages in English: the cover, then the features and the specification table. Jack shows the servo drive, automatic presser foot lift and thread trimming, the dot-matrix panel and the short thread build that keeps the thread end within 3 mm on thin woven material.

Longer buttonholes need the JK-T782G or JK-T783G, which we quote on request. Al Borj supplies, installs and services the JK-T781G from Sharjah and Accra.
