Computer-controlled, High-speed, Lockstitch Buttonholing Machine

Thanks to the multiple knife-dropping function, it is no longer required that the knife be changed at the buttonhole size is changed. The knife supports sewing lengths of 41mm at the maximum. In addition, knife mechanisms for 70mm and 120mm are optionally available. With this, slots such as the belt holes of child seat belts can be buttonholed. 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). LBH-1796A: Buttonholing machine with a 220mm work clamp which supports the simplified indexer function has been added to the family of buttonholing sewing machines. LBH-1790AB: Computer-controlled, High-speed, Buttonholing Machine with a shorter-thread remaining function. The newly-developed shorter-thread remaining mechanism trims the thread short and eliminates the trouble of manual thread nipping.
