JUKI AMS Series – Computer-Controlled Cycle Sewing Machine with Input Function

The JUKI AMS Series represents the next generation of programmable cycle sewing systems. Designed with powerful automation features and proven JUKI reliability, these machines deliver record-breaking speed, improved energy economy, and enhanced stitch quality for modern manufacturing. Ultra-High Productivity The AMS Series achieves the industry's fastest sewing speed of 2,800 stitches per minute, reaching maximum speed by the second stitch and maintaining it until the final phase of sewing. This dramatically reduces cycle time. A JUKI-developed stepping-motor controlled thread trimming system ensures rapid and consistent thread cutting, while the direct-drive main shaft servomotor improves responsiveness and accelerates cycle completion. High Speed at Longer Stitch Pitches The machine maintains its top speed of 2,800 sti/min up to a stitching pitch of 4 mm, the highest capability in the industry. For larger stitch lengths, speeds increase significantly versus older models: Up to 90% faster on AMS-210EN Up to 60% faster on AMS-221EN The system automatically controls sewing speed according to stitch pitch for optimum performance. Energy-Efficient Design The AMS Series reduces power consumption by approximately 30% (vs. the previous AMS-210E). It utilizes: A compact AC servomotor for direct drive (high energy transmission efficiency) An encoder-controlled stepping motor that adjusts power usage based on fabric thickness and stitch length This results in quieter operation, lower heat output, and reduced running cost. Superior Stitch Quality & Accuracy The encoder-controlled X-Y stepping motor allows operators to verify feed position during sewing. This provides: High accuracy in pattern stitching Reduced deformation when sewing at high speed Reliable results even on heavy-weight or multilayer materials Semi-Dry Head – No Oil Stains The needle bar and thread take-up system use grease lubrication, while the hook is fed a tiny, controlled quantity of oil from a tank. This prevents oil staining, protects the garment, and extends machine life. Programmable Intermediate Presser The lower dead point of the intermediate presser can be adjusted steplessly during sewing: Standard: 0–3.5 mm Maximum: 0–7.0 mm Stroke adjustable up to 10 mm This ensures stable clamping of multi-layered materials, preventing thread breakage, skipped stitches, or material shifting. Multiple Feeding Frame Configurations Two frame types are available: Monolithic feeding frame Separately-driven feeding frame Left and right sections operate independently Each side can have different lifting heights and movement speeds The feeding frame also supports a double-stepped lowering function for precise material alignment. Active Thread Tension System JUKI’s Active Tension allows stitch-by-stitch tension adjustment according to fabric thickness and sewing direction. Benefits: Perfect tension reproducibility Expanded sewing range Faster changeover between processes Supports Wide Sewing Applications The AMS Series handles: Free pattern sewing Reinforcement sewing Shape tacking Name labels, badges, emblems Velcro attachment Special bartacks and decorative operations IP-420 Large Color LCD Touch Panel The standard IP-420 panel provides a wide-screen, multilingual interface with advanced editing tools: Real-time stitch shape preview Tension display Enlargement/reduction ratio Speed setting Stitch count display 14 language options Programmable function screens Simplified mode to reduce operator fatigue Includes key-lock mode to hide sensitive settings from operators. High-Capacity Data Storage & USB-Ready Body The sewing machine’s main body includes large internal storage: Up to 500,000 stitches 999 patterns Up to 50,000 stitches per pattern Multiple media types are supported via USB interface: USB thumb drive Floppy (FD) SmartMedia (SM) CompactFlash (CF) Secure Digital (SD) Card reader options Maximum data capacity per media: ~50,000,000 stitches.
