JUKI LK-1905CSP Computer-Controlled Programmable Pattern Sewing Machine – 60mm x 50mm Sewing Area

The JUKI LK-1905CSP is a high-speed, computer-controlled industrial pattern sewing machine designed for programmable stitching within an expanded 60mm (X) x 50mm (Y) sewing area. Built for manufacturers who need repeatable, consistent stitching beyond a traditional bartack, the LK-1905CSP is an excellent solution for box stitches, reinforcement patterns, elastic joining, hook-and-loop fastener attachment, labels, patches, and other programmable sewing operations.

With its electronically controlled X-Y feeding system, programmable sewing patterns, automatic work clamp lift, automatic thread trimming, and electronic thread tension control, the LK-1905CSP helps automate repetitive sewing operations while improving consistency from one piece to the next.

Why Choose the JUKI LK-1905CSP?

Unlike a conventional bartacking machine that is primarily intended for predefined reinforcement stitches, the LK-1905C expands the sewing field to 60mm x 50mm, allowing it to perform larger and more complex programmable patterns.

This makes the machine especially useful when an operator would otherwise need to manually guide the material to create the same stitch pattern repeatedly. Once the appropriate sewing pattern and work clamp are set up, the machine can reproduce that operation consistently—helping improve productivity, stitch placement, and finished quality.

**Please note this machine is the Medium Weight version 

60mm x 50mm Programmable Sewing Area

The expanded 60mm (X) x 50mm (Y) sewing field accommodates a wide range of programmable stitch patterns.

JUKI identifies applications including:

• Elastic tape joining and reinforcement

• Box stitching

• Hook-and-loop fastener attachment

• Men's and women's apparel

• Denim products

• Knitwear

• Reinforcement stitching

• Other custom programmable sewing patterns

The larger sewing area makes the LK-1905C an excellent choice for manufacturers looking for greater flexibility than a standard electronic bartacker.

Intermediate Presser for Improved Material Control

The LK-1905CSP configuration incorporates an intermediate presser, an important feature for more complex pattern-sewing applications.

The intermediate presser helps prevent the material from flapping or shifting during sewing. This improves material control and helps produce cleaner, more consistent results, particularly on patterns that contain frequent changes in stitch direction, size, or shape.

Programmable Pattern Sewing

The LK-1905C can store up to 999 patterns, allowing frequently used sewing operations to be saved and recalled instead of manually recreating the stitch each time.

Pattern enlargement and reduction from 20% to 200% in 1% increments provides additional flexibility when adapting patterns for different products and applications.

The machine's internal memory can store up to 500,000 stitches, giving production facilities the ability to maintain a substantial library of sewing programs.

High-Speed Direct-Drive Performance

The LK-1905C operates at speeds up to 2,700 stitches per minute, providing the productivity required for repetitive industrial sewing operations.

A 550W compact AC servomotor is incorporated into the direct-drive system, eliminating the traditional belt-driven arrangement and helping provide responsive operation with reduced vibration and noise.

Active Electronic Thread Tension

JUKI's Active Tension electronic thread tension control system allows thread tension to be electronically controlled according to the sewing conditions.

This helps manufacturers establish repeatable sewing settings for different materials, threads, patterns, and applications rather than relying entirely on manual tension adjustments.

Automatic Work Clamp Lift

A stepping-motor-controlled automatic work clamp lifter is standard.

The work clamp foot lift is normally 14mm and can reach 17mm when using the reverse-rotation needle-up function, providing clearance for positioning and removing materials.

Designed for Repeatable Production

The primary advantage of a programmable pattern sewing machine is consistency.

For repetitive manufacturing operations, the LK-1905CSP allows the sewing pattern to be programmed and reproduced automatically. This can help:

• Reduce dependence on operator-guided stitching

• Improve consistency from piece to piece

• Reduce sewing cycle times

• Improve stitch placement

• Simplify repetitive reinforcement operations

• Produce a more uniform finished product
