Description
Computer-controlled, High-speed, Buttonholing Machine (Shorter-thread remaining functions)
The newly-developed shorter-thread remaining mechanism trims the thread short and eliminates the trouble of manual thread nipping. Needle thread tension for sewing parallel and bartacking sections of buttonholes can be separately controlled through the operation panel and stored in memory according to various sewing conditions (e.g., type of thread, type of material and sewing speed).
