Juki LBH-1790S-S
High-Speed, Computer-Controlled Buttonhole Sewing Machine - Simple Series
The Juki LBH-1790S-S from the Simple Series is engineered to deliver Juki's renowned seam quality while simplifying operations for efficient buttonholing. This computer-controlled machine integrates advanced features to enhance productivity and ease of use, making it ideal for both high-volume and small-lot production environments.
Key Features:
Voice Guidance System for Enhanced Productivity The LBH-1790S-S is equipped with a voice-guidance system that supports operators by providing real-time production information. This includes data on the number of pieces produced, work progress, and machine operation rates. This intuitive feature helps streamline workflows and maintain consistent production quality.
Easy Adjustments and User-Friendly Operation With a simple operation panel, setting functions like pattern numbers and needle thread tension is straightforward. The machine also allows for easy adjustments to the distance between buttonholes through its enlargement/reduction feature. The integrated USB port facilitates effortless data management and software updates.
Unmatched Sewing Speed and Efficiency Achieve higher productivity with the LBH-1790S-S's impressive maximum sewing speed of 4,200 stitches per minute. Its rapid acceleration and deceleration, combined with increased thread trimming speed and enhanced auto-lifter performance, significantly reduce cycle times.
Electric-Driven Mechanism for Stable Sewing The machine's key components, including the work clamp foot lifter, needle/bobbin thread trimmers, and thread tension controllers, are electrically driven. This design ensures stable, high-quality seams while minimizing operating noise and vibration.
Adjustable Work Clamp Foot Height The LBH-1790S-S features an adjustable work clamp foot that can lift up to 17 mm, accommodating a wide range of materials, including heavy fabrics. This flexibility is particularly useful for sewing bulky knits and other thick textiles.
Advanced Thread Tension Control With the Active Tension system, the needle thread tension can be precisely adjusted for different sections of the buttonhole seam. This allows for optimal thread tension throughout the sewing process, ensuring beautifully finished seams without thread slip-offs or unraveling.
Basting Stitch Capability for Elastic Materials The machine's basting stitch function is especially effective on elastic materials like knits. This feature tucks in the needle thread securely, preventing it from protruding and maintaining the integrity of the buttonhole seams.
Automatic Knife Adjustment Juki's unique multiple-times knife dropping function eliminates the need for frequent knife replacements, even when buttonhole sizes change. This is particularly beneficial for small-lot production where varying sewing sizes and patterns are common.
Versatile Stitching Options Switching between purl stitching and whip stitching, as well as between single and double stitching, is seamless. The LBH-1790S-S supports 31 standard buttonholing shapes and can store up to 99 custom patterns, all easily selectable through the operation panel.
