A new, higher level of advanced mechatronics has been ideally achieved by the grafting of the newly developed, automatic thread trimming Fortuna AC servo motor, equipped with the most up-to-date function, to our 1needle high speed lock stitch machine with automatic thread trimmer; various functions created for operational convenience. This new product will greatly contribute to upgrading sewing pattern quality and productivity increase. 14mm The thread take-up made of special aluminum enables for maximum sewing speed 5,500 spm (Normal speed 5,000 spm). The high-performance impeller pulp is used to enhance durability of the internal moving section of the sewing machine. Feed dog's ideal trace and seaming structure specially designed for Low tension sewing minimize the puckering. At the same time, straight of sewing is very excellent. Thread-trimming mechanism increases abrasion and durability with special material of moving and fixed knife, The remaining thread after trimming is minimized, leaving the shortest remaining thread among similar types of machine. A number of accessories are offered to improductivity. The soft-touch reverse button and the attachment sheet 14mm lift of presser foot, highest record among the sewing machines of similar grade KM-250AU series The intensive research on feed dog traces, thread take-up, needle bar and thread adjusting device has resulted in achieving good-quality sewing without puckering, even when handling ultra thin or new materials. KM-250AU Series KM-250B & KM-250BH Series The engineering plastic inner oil container made of special materials completely bans sewing materials from being tainted with oil. It is suitable for high-end sewing materials. Feeding & seaming mechanism not only for medium thick material but also for ultra heavy material guarantees powerful stitching and perfect seaming. Longer thread take-up stroke 7mm of maximum stitching length, both make ultra heavy material stitching much better.(KM-250B Series) Compact-type auto knee lifter solenoid attached directly to the machine head in the back minimize loss of power. It is connected and disconnected easily. It also helps for better operation by providing enough space in the lower part of table (Option).
