Description
The BRUCE BRC-T1790G is a high-speed, computerized electronic lockstitch straight buttonholing machine engineered for industrial apparel production.Driven by an advanced servo and closed-loop stepper motor system, it delivers exceptionally stable stitching with minimized noise and vibration compared to traditional mechanical machines.
A core highlight of the BRC-T1790G is its specialized handling of both lightweight woven materials (like formal shirts and workwear) and highly elastic knitted fabrics (such as T-shirts).
Key Features
- Closed-Loop Stepper Drives: The needle swing (pendulum), fabric feeding mechanism, and presser foot lifting are all independently controlled by closed-loop stepper motors, ensuring flawless stitch accuracy and fast knife-dropping response speeds.
- Short Thread Head Trimming: Equipped with an electronic short-thread mechanism that cuts and leaves the remaining thread tail under 2.5 mm. This completely eliminates the need for manual manual thread trimming after production, reducing factory labor costs.
- Electronic Thread Tension Control: Features a programmable electronic thread clamp. This allows operators to set variable thread tension levels for different fabric types and sewing stages, preventing thread breakage or loose stitches.
- Knitting Adaptability: The specialized “GK” variant includes a dedicated knitting presser foot, a minimized needle plate, and an elastic-optimized cloth carrier to secure highly flexible fabrics without distortion.
- Multi-Cut Functionality: The machine utilizes a computerized multi-cut sequence. It can cut longer buttonholes by dropping the knife multiple times, removing the need to physically change out the internal knife blades for different buttonhole lengths.
- Top & Bottom-Line Detection (Optional): Supports intelligent bobbin-thread monitoring that stops operation and alerts the user right before the bobbin thread runs out, ensuring no lost cycles or empty runs.
Operation & Cleanliness
- Semi-Dry Machine Head: The internal hook and machine head utilize advanced oil-free / minimum lubrication technology, completely preventing oil spots or stains on pristine white garments.
- Smart LCD Touch Panel: A responsive, modern user interface allows operators to adjust panel sensitivity, modify stitch patterns, and manage cycle configurations directly from the screen.
