Detail

How it runs on the floor

The JACK C7-6-03/333 "Urus" is a 6-thread AI-powered overlock machine featuring JACK's A.M.H. (Automatic Material Handling) system — adaptive intelligence that continuously monitors fabric properties and adjusts feeding force and presser foot pressure in real time, up to 32,000 corrections per second. The result is consistent stitch quality at up to 7,000 SPM across any material type — thick, thin, elastic, or rigid — without operator intervention or speed reduction. Three operating modes (Manual, Semi-Automatic, and Automatic) allow operators to dial in the level of automation that fits their workflow. This is a complete setup shipped with industrial table and stand included.
