LK-1900A

Computer-controlled, High-speed, Bartacking Machine

The world's highest sewing speed of 3,000rpm !
The proven computer-controlled bartacking machine has been dramatically evolved to be an easier-to-use machine.

Higher productivity.

The machine achieves the world's highest sewing speed of 3,000rpm.

In addition to the high-speed sewing performance, the machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time (reduced approximately 30% compared to our predecessor model: For 42-stitch large bartacks).

Excellent seam quality.

The machine comes with a newly developed needle thread grasping mechanism. The mechanism prevents thread from slipping off from the needle eyelet at the beginning of sewing, from tangling on the wrong side of the material and also being stained during sewing.

The thread trimming mechanism has been further improved to shorten the length of thread remaining on the wrong side of the material after thread trimming.

Wider sewing area and many different sewing patterns.

With its 30mm (length) by 40mm (width) sewing area, the machine can sew many different shapes of bartacks.

The machine is provided as standard with as many as 50 different types of sewing patterns including semilunar bartacking, round bartacking, radial tacking as well as conventional bartacks.

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

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 just clean oil is supplied from the oil tank to the hook.

The machine is provided as standard with the active tension (electronic thread tension control mechanism).

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 (IP-200B) 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.

A wide choice of subclass models of LK-1900A.

The LK-1900A 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) and W type (with a large shuttle hook for heavy-weight materials), 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.
