Call us for prices and more information.
LK-1900B
The machine achieves sewing speed of 3,200sti/min. The machine’s starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time.
LK-1901B (eyelet buttonholes)
The machine is provided with a material-drawing mechanism which draws the right and left parallel portions of an eyelet buttonhole near to one another. The machine performs bartacking with the right and left parallel portions of the eyelet buttonhole drawn near to one another after the buttonhole is clamped under the work clamp foot, thereby finishing highly durable and well-tensed eyelet buttonholes.
LK-1902B (belt-loop-attaching)
The machine is provided as standard with six different linear bartacking patterns. 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. If the normally used patterns are assigned to the patterns keys, a desired pattern can be called up or changed with single-key operation.
