FB-230-4000 Rear Tensionfree Curtain Multi-Needle Sewing Unit
Technical Features
One-Step Dual-Stitch Formation: The specialized multi-needle chainstitch head executes two parallel stitch lines simultaneously, effectively doubling throughput while eliminating the twisting, lifting, and puckering caused when two passes are sewn independently.
Wide Header Band & Tape Compatibility: Easily accommodates 22-needle or 33-needle chainstitch setups, specifically engineered to attach and secure 10 cm to 16 cm (100–160 mm) curtain heading tapes, buckram, and decorative lace borders in a single pass.
Full Computer & One-Key Digital Operation: Intuitive microcomputer interface with one-touch operation allows entry-level operators to produce technician-grade drapery with minimal training.
PLC & Multi-Servo Synchronous Control: Centralized microcomputer PLC synchronizes the main sewing drive, stretchable conveyor transport belt, and tension devices to ensure straight, stress-free seam paths across long panel lengths.
Automatic Fabric Clamping & Dynamic Pulling Device: Features an intelligent clamp-and-pull system with freely adjustable tension force and three memory preset groups to instantly recall optimal tension settings for recurring fabric qualities.
Interchangeable Quick-Insert Pull Barrel Design: Modular pull barrel/folder tooling enables rapid, tool-less switching between different tape widths, pleat styles, and edge folds for one-step finish execution.
Hands-Free Triple Foot Pedal Control: Ergonomically designed three-pedal assembly gives operators effortless, responsive manual control over starting, stopping, and repositioning without taking their hands off the workpiece.
Customizable Extended Conveyor Platform: Built on an expansive 4.0-meter rolling conveyer table structure designed to support extra-long drapery drops and prevent material weight from distorting seam tension.
Primary Applications
Curtain Header Tape Attachment: High-speed application of 10–16 cm reinforced header tape, pinch-pleat buckram, and eyelet lining strips.
Simultaneous Double-Line Chainstitching: Parallel structural edge stitching on drapery borders, sheer fabrics, jacquards, and velvet curtains.
Long-Panel Fabric Joining & Banding: Flat, continuous tape joining and decorative band attachment without tension-induced wave distortion.
Contract & Commercial Drapery Manufacturing: High-volume output for hospitality window treatments, villas, commercial venues, and residential curtains.
