LK-1900B Series
Computer-controlled, High-speed, Bartacking Machine
The sewing machine eliminates so-called bird's nests (thread tangling in on the wrong side of the material at the beginning of sewing). Length of thread remaining on the material at the end of sewing has been reduced to 2 mm or less.
The machine is provided with an active tension mechanism which enables the electronic control of stitching.

Product overview
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.
Higher Productivity.
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. (Low-noise and low-vibration)
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.
he 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.
For LK-1900BB, the standard no. of sewing patterns is 50.
The LK-1900B 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 (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-420U 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.
Many different models are prepared according to the type of materials
  • The LK-1900B 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 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. 
STANDARD LIQUID CRYSTAL PANEL (NEW)
  • 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.
  • Standard sewing patterns can be assigned to pattern keys P1 to P50. Any 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.
  • As many as 99 different cycle sewing patterns, each of which combines a maximum of 99 different sewing patterns, can be stored in the memory.
