AI material-recognition lockstitch — the machine senses fabric weight and adjusts tension automatically. The flagship single-needle for shops that switch fabrics constantly and don't want operators re-tuning between every job.
Contract apparel shops that mix fabric weights through the day — cotton in the morning, denim in the afternoon, performance fabric for a specialty run. Operator setup time on tension changes is the cost the AI4 eliminates.
Sample rooms and prototyping shops where every job is a different fabric. Tension tuning that used to take 5 minutes per fabric change becomes zero — the machine handles it.
Mixed apparel run
Apparel shop running 4 different fabric weights in a single shift. AI tension means the same operator handles all four without setup time between jobs.
Sample room
Prototype lab making one-off samples for client review. Each sample is a different spec; tension tuning is the dominant cost the AI4 eliminates.
Repair shop
Multi-piece-per-day alterations and repairs across cotton, denim, wool, and performance fabric. Different tension needed for every piece — auto-tension makes the machine truly walk-up.
Machine assembled with AI tension control system, integrated direct drive motor, industrial table and stand.
