Computer-controlled, High-speed, Bartacking Sewing System

Machine is mounted with inbuilt NFC (Near Field Communication) and communication devices capable of a 2-way data transmission.

Higher productivity.

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.

Excellent workability and operability

The direct-drive head (with no belt), which is directly connected to a compact AC servomotor, achieves outstanding. This head helps create a comfortable working environment with reduced vibration and noise.

The arm section of the machine head is fitted with a hand pulley. This allows the operator to visually check the needle entry points.

Excellent seam quality.

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.)

Many different sewing patterns.

The machine is provided as standard with 51 different sewing patterns. The machine permits easy changeover of sewing patterns for effortless execution of an inexhaustible range of sewing specifications.

The LK-1900BN is also able to sew buttons using the same data used for the LK-1900 (EP-ROM).

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.

Auto-lifter mechanism utilizing a system.

The machine is provided as standard with auto-lifter that uses a 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 17mm. (Standard 14mm)

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.

Eco-friendly power saving

An encoder is installed in the pulse motor, thereby achieving substantially improved power-consumption saving.

The machine is provided as standard with the active tension

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, base stitched part, zigzag stitched part and end of the seam (fastening stitch).

When the operation panel is used in combination with the active tension, the needle thread tension can be set on a stitch-by-stitch basis. This helps eliminate undesired thread tension variations at a multi-layered part of a material or with sewing direction, thereby contributing to upgraded seam quality.

Standard panel

Management of sewing performance and sewing machine by the utilization of IoT (Internet of Things)

Data on sewing machine adjustments made according to the product to be sewn can be transferred to a commercially-available Android tablet in contactless mode. This enables quick check for uniform settings as well as confirmation of conditions of sewing machines in a sewing line, thereby facilitating setup changes.The operation panel is also provided as standard with a USB port. Data management and software update can be carried out with ease using a USB thumb drive.

Data items of sewing can be numerically managed to ensure "stable quality" and "reduction in time required for setup changes".Quantified sewing data can be externally taken from the sewing machine using an Android tablet or USB thumb drive.

Many different models are prepared according to the type of materials.

The LK-1900BN model comes in five different subclass models, such as S type (standard), H type (for heavy-weight materials), F type (for foundation), M type (for knits and knitted materials) , W type (with a large shuttle hook for heavy-weight materials) and (bird's nest preventing /shorter-thread remaining functions) , to offer a choice according to any application.

The needle's penetrating force into the material has been increased. This provides an improved responsiveness to heavy-weight materials for the H type machine.

The W type has adopted a large shuttle hook, which reduces the frequency of bobbin-thread changing to enable highly efficient sewing work.
