Description
The BRUCE BRC-6390 (often designated as BRC-6390E or BRC-6390B) is a heavy-duty, computerized single-needle industrial lockstitch sewing machine. It is manufactured by Jack Technology and features a specialized dual-synchronous top and bottom feeding mechanism (walking foot). This architecture ensures flawless material transport when sewing thick, sticky, or multi-layered fabrics without layer shifting.
Key Features
-
- Feeding Mechanism: Dual synchronous top and bottom feed (Walking Foot + Feed Dog).
- Maximum Speed: Up to 2,200 stitches per minute (adjustable).
- Maximum Sewing Thickness: Handles materials up to 16mm thick.
- Stitch Length: Varies by variant, with long-stitch models supporting up to 12mm.
- Hook System: Enlarged vertical axis rotary hook to accommodate thick industrial threads and reduce bobbin changes.
- Bed Configuration: Flat-bed design with standard 220V 50Hz single-phase operating voltage.
Automated Computerized Features
-
- Direct-Drive System: Built with a powerful integrated direct-drive servo motor that connects via a single-shaft structure to maximize stable needle penetration power while reducing noise and vibration.
- Full Automation: Features automated thread trimming (auto-trim), automatic presser foot lifting via pedal feedback, and programmable automatic back-tacking (reverse stitch reinforcement).
- Needle Positioning: Adjustable computerized needle up/down stopping positions.
- Oil-Free Top Mechanism: Utilizes a specialized closed-lubrication design to prevent oil splatters and stains on premium workpieces like leather or canvas.
- Smart Panel Control: Includes an integrated digital control panel with a “one-key reset” feature to instantly restore default manufacturing sewing parameters.
Primary Industry Applications
The synchronized movement of the upper walking foot and lower feed dog prevents fabric slippage, making the BRC-6390 highly efficient for structural sewing across:
- Leather products (bags, footwear, upholstery, and furniture casings).
- Heavy automotive and industrial components (car mats, EVO carpets, and safety straps).
- Outdoor equipment (tarpaulins, heavy-duty canvas bags, tents, and PVC sheets).
