Juki LK-1900S Industrial Bartack Machine Features
High Productivity Sewing Performance
The LK-1900S achieves a maximum sewing speed of 3,200 stitches per minute, reducing production time while maintaining excellent stitch consistency. Faster acceleration, deceleration, thread trimming, and clamp foot movement contribute to increased efficiency in manufacturing environments.
Computerized Pattern Control
The machine comes with 51 built-in sewing patterns and allows operators to store up to 200 custom patterns with a maximum memory capacity of 20,000 stitches. This flexibility enables quick switching between production requirements.
Pattern Scaling Function
Patterns can be enlarged or reduced from 20% to 200% in 1% increments by adjusting stitch length, allowing precise customization without changing the overall design.
Direct-Drive Servo Motor
The integrated direct-drive AC servo motor delivers smooth operation, reduced vibration, lower noise levels, and improved energy efficiency compared to conventional belt-driven systems.
Semi-Dry Lubrication System
The semi-dry head minimizes oil contamination while maintaining reliable lubrication for critical components. The hook utilizes minute-quantity lubrication to ensure long-term durability.
Automatic Work Clamp Lifter
The standard stepping-motor-driven work clamp foot lifter improves productivity and reduces operator fatigue during repetitive bartacking operations.
Applications
- Garment manufacturing
- Workwear and uniforms
- Jeans and denim production
- Backpacks and luggage
- Leather goods
