The machine realizes high speed 3,200rpm. In addition to the high speed sewing performance, cycle time can be substantially decreased.
With needle thread nipper, which prevents thread slipping off from the needle hole at the beginning of sewing, and bird-nest problem on the bottom side, and also oil stain problem. For the advanced thread trimming mechanism, the remained thread-end can be shortened.
The With 30mm X 40mm (L x W) sewing area, the machine can sew 50 patterns of bartacks, including common shapes, half-moon, round, radical tacking. The machine can sew by the same data of LK-1900 and LK-1900AN (EP-ROM, EEPROM).
With dry-head technology, the frame (needle bar, thread take-up) no longer requires oil-lubrication. Just a small quantity of clean oil is supplied from the oil tank to the shuttle hook.
With active tension mechanism, it can set a needle thread tension that matches various sewing conditions (such as thread, material, sewing speed…) on the operation panel, store the data in memory or reuse. The needle thread tension can be separated according to stitching type or portion of a seam, such as the beginning part, base part, zigzag part and ending part (fastening stitch). With operation panel IP-410B, the tension can be set on a stitch-by-stitch basis. This eliminates undesired thread tension variations at a multi-layered part of material or with sewing direction, which upgrades seam quality.
Auto-lifter can be set as one-step stroke or double-step stroke, which offers easier sewing material handling. For the double-step stroke, an intermediate stopping height can be set on the operation panel. The presser foot lifter can be set to 17mm Max. by using the reverse-rotation needle-up function in combination with the auto-lifter mechanism.
The direct-drive head (without belt), which is driven by compact AC servo motor, realizes outstanding responsiveness and improved stop accuracy, which provides a comfortable working condition with low vibration and noise. The arm section is equipped with a hand wheel. Operators can visually check the needle entry points.
Auto-lifter can be set as one-step stroke or double-step stroke, which offers easier sewing material handling. For the double-step stroke, an intermediate stopping height can be set on the operation panel. The presser foot lifter can be set to 17mm Max. by using the reverse-rotation needle-up function in combination with the auto-lifter mechanism.The sewing starting point can be shifted in X/Y direction. This enables the correction of a sewing pattern in accordance with the presser foot configuration.
With 6 patterns of linear bartacks. Since the sewing size can be easily changed, the optimal number of stitches and sewing size can be speedily selected according to the belt-loop width.
With its broadly curved feed bracket (presser arm), the machine provides easy placing of sewing material. The slim shape bed and head design makes free space under the arm demonstrates greater operability in handling sewing materials, which increases production efficiency.
The machine achieves sewing speed as 2,700rpm Max. with quick starting and stopping. Providing 50 sewing patterns, which changeover is easy to be set. With optionally equipping ABF autobutton feeder, LKS-1903AN can reach the highest production efficiency.
