High-speed button sewing machine achieving 2,700 sti/min. LCD panel and control box integrated with the machine head. Stores up to 999 patterns (500,000 stitches). Active tension mechanism for consistent seam quality. Available with optional button feeder (BR35) for automated button supply. Reduces noise by approximately 40% and power consumption by 26% vs predecessor models.
The LK-1903C achieves sewing speed of 2,700sti/min. The machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time. This is a lockstitch button sewing machine that supports a variety of sewing patterns and cycle sewing.
The control box integrated with the machine head, originally designed by JUKI, is adopted. The number of standard patterns is 50. As many as 999 patterns (500,000 stitches) can be stored in memory. The new upright type operation panel is installed on the side face of the machine head to allow the operator to operate the machine without averting his/her eyes, during sewing, from the bartack being sewn. In addition, the table surface can be used widely. The operation panel can also be installed on the table as before. ●If you want to install the operation panel on the table, an optional connecting cable (1.2 m) will be necessary.

●The machine achieves sewing speed of 2,700sti/min.The machine’s starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time. ●With our original horizontal forced feed mechanism, the button carrier sets a button in position so that the operation is simplified. Even first-time operators can achieve stable sewing quality by simply setting the fabric and pressing the pedal.

●Since the machine is provided with an active tension mechanism, it is able to set a needle thread tension that matches various sewing conditions (such as thread, material and sewing speed) on the operation panel, store the data in memory and reproduce it. ●The needle thread tension can be separated according to stitching type or portion of a seam, such as the beginning part of the seam, in the middle of sewing and end ofthe seam (fastening stitch).
Needle thread grasping mechanism helps produce consistent knot tying at the beginning of sewing. (This device has been factory-set to “invoking prohibited” status at the time of delivery.) ●In the case “T” is selected for the work clamp foot/thread clamp
