Key Features

A.M.H. (Automatic Material Handling) — real-time AI sensors detect thickness changes at fabric seams and automatically calculate the optimal ratio between presser foot pressure and feed dog force
Smart Rhino Feeding System — motor detects thickness changes in real time and increases torque up to 9.2 Nm to maintain constant speed even on heavy materials
Presser Foot Transformer — intelligent perception with 32,000 detections/second and microsecond pressure response using 1+ million data models
Active sensor presser foot — modulates pressure during sewing, raising automatically at seam junctions to facilitate passage of thick fabrics
Digital presser foot lift up to 7mm — controlled by stepper motor for maximum precision on heavy-duty applications
Three operating modes: Manual (full pedal control), Semi-Automatic (auto cut/lift with photocells), and Fully Automatic (photocell-only hands-free operation)
Digital thread trimmer — stepper motor controlled (not magnetic), short cut up to 5mm
Sewing speed up to 6,000 SPM optimized for heavy-weight production
Intuitive panel with voice guide and quick-access keys
Mechanical L/M/H selector — lever to adjust feed dog ellipse height for light/medium/heavy fabrics
Minimal design — no external cables, magnets, or devices; everything integrated for quick cleaning
Industry 4.0 ready — built-in WiFi for App or WebApp connection, production monitoring, parameter adjustment, and maintenance notifications via Jack cloud
3-step LED work area lighting — adjustable brightness for optimal visibility

Available Options

Chaincutter Waste Suction (KS/KH) — front suction for material scraps, rear suction for cut threads to keep seams clean
Automatic Batchlatch (BK) — device to prevent fabric damage during chain return formation
Semi-Dry System (W) — grease lubrication with DLC (diamond-like carbon) needle bar to prevent oil stains on fabrics

Ideal For

Garment factories producing workwear, uniforms, denim, and heavy-duty apparel
Operations working with medium to heavy-weight fabrics requiring robust seam construction
Commercial sewing rooms needing consistent overlocking on thick knits, canvas, and multi-layer seams
High-volume production lines requiring automated material handling and reduced operator fatigue
