Computer-controlled, High-speed, Lockstitch, utton ewing Machine LK-1903 LK-1903/R35 (with button feeder) LK-1903--301 (Table stand is optionally available.) EM ccreditation IO14001:1996 RE005 REG.NO.JE389 089 HED OFFICE The environmental management system to promote and conduct ➀the technological and technical research, the development and design of the products in which the environmental impact is considered, ➁the conservation of the energy and resources, and the recycling, in the research, development, design, distribution, sale and maintenance service of the industrial sewing machines, household sewing machines and industrial-use robots, etc. and in the purchase, distribution and sale of the household commodities including the healthcare products.
LK-1903 Higher productivity. The machine achieves sewing speed of 2,700rpm. The machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time. Many different sewing patterns. The machine is provided as standard with 50 different sewing patterns. The machine permits easy changeover of sewing patterns for effortless execution of an inexhaustible range of sewing specifications. The LK-1903 is also able to sew buttons using the same data used for the LK-1903 (EP-ROM). Excellent seam quality. Newly developed 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.) uto-lifter mechanism utilizing a new system. The machine is provided as standard with auto-lifter that uses a new stepping-motor system. This helps reduce operator fatigue. It is also possible to change over the stroke of the auto-lifter from a onestep stroke to a double-step stroke, which offers easier positioning of a material on the machine. For the double-step stroke, an intermediate stopping height can be established on the operation panel. The work clamp foot lift can be set to a maximum of 13mm. The sewing starting point can be corrected. In cases where the needle entry point for button sewing is to be corrected, the sewing starting point can be corrected without the adjustment of the relevant mechanism. ctive tension LK-1903--301 The machine is provided as standard with the active tension (electronic thread tension control mechanism). ince the machine is provided with 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 set separately according to the portion of a seam, such as the beginning of a seam, during sewing and end of the seam (fastening stitch). When the operation panel IP-200 is used with the machine, the needle thread tension can be established on a stitch-by-stitch basis for upgraded seam quality. Oil stains are eliminated. Thanks to our advanced dry-head technology, the frame (needle bar and thread take-up) no longer requires lubrication. This prevents the material from being stained with lubricating oil. Just a small quantity of clean oil is supplied from the oil tank to the hook. OPERTION PNEL (You can choose operation panel.) TNDRD PNEL Functional settings, such as pattern numbers and needle thread tensions can be established through the operation panel with ease. Distance between holes in a button can be easily changed by means of pattern enlargement/reduction feature. tandard sewing patterns can be assigned to pattern keys P1 to P50. ny of the sewing patterns assigned to the P1 to P25 pattern keys can be activated with a touch of the corresponding key. This means that workability is improved by assigning 25 sewing patterns that are most frequently used to those pattern keys. s many as 20 different cycle sewing patterns, each of which combines a maximum of 30 different sewing patterns, can be stored in the memory. The operation panel has been installed at an angle and can be placed at the top, bottom, right or left part of the table according to the operator's preference. IP-200 large color LCD touch panel has been adopted for the display. It gives clear displays that allow the operator to understand operating procedures. The IP-200 panel can be connected to a personal computer and can store data on martmedia. This allows data to be exchanged or shared among sewing machines installed in a factory or among remote factories. The IP-200 panel has been provided with a process improvement supporting feature through the indication of the operational state of the sewing machine, and a maintenance and management feature for indicating the needle changing timing and cleaning timing.

LK-1903 /R35 Newly developed machine head, LK-1903 is adopted. LK-1903/R35 is now available. It provides better productivity as it achieves the maximum With our original horizontal forced feed mechanism, the speed of 2,700rpm (2,500rpm in normal use) and is button carrier sets a button in position so that the equipped with the high speed trimmer. operation is simplified. Furthermore, operator fatigue is reduced since what operator needs to do is only setting material and pressing a pedal. LK-1903-311/R35 OPERTION PNEL The variety of functions can be easily adjusted by the simplified operation panel. larm lamp will be activated when problem is detected so that proper measures can be taken quickly. utomatic supply mode The machine and button feeder are connected and run together. It starts sewing a button by pressing a pedal, thread trimmer is activated after sewing a button, and button feeder sets the next button in position automatically. The machine repeats these operations with this mode. Mode for individual This mode is for the machine only. s button feeder will not be activated, this can be used as a standard button sewing machine. Mode for small lots ame as the automatic mode, but parts feeder will not be activated. It discharges the required amount of buttons in the index and sews buttons automatically. This is suitable for smaller lots.
