The Shibang 2530/2533/2534 Synchronous Herringbone Stitching Machine is a high-performance, industrial-grade sewing solution designed for precision herringbone stitching on a wide range of materials including thick leather, upholstery fabrics, automotive interiors, and heavy-duty textiles. Equipped with advanced synchronous feed technology, a powerful direct drive system, and durable build quality, this machine is engineered for consistent, neat, and strong stitching results even under intensive production conditions.This machine series—2530, 2533, and 2534—represents a new standard in synchronized compound feed technology, enabling smooth material feeding, superior stitch balance, and enhanced operator comfort. Designed with meticulous attention to production efficiency and stitch integrity, it is ideal for manufacturers who demand perfection in decorative or structural herringbone seams.

Key Advantages & Features

Advanced Synchronous Feeding Technology

The Shibang 2530/2533/2534 series features synchronous compound feed, combining bottom feed, needle feed, and upper feed mechanisms in perfect synchronization. This allows precise control of fabric layers and stitch spacing, preventing material slippage or puckering even on complex or heavy materials. The synchronization of feed components minimizes needle deflection and thread tension variations, delivering a uniform herringbone pattern every time.

Optimized for Herringbone Stitching

Unlike conventional machines, this model is purpose-built for herringbone or double-needle decorative stitching. It delivers:

• Strong seam integrity

• High stitch density control

• Precise stitch alignment across curves and seams This ensures that even ornamental herringbone designs look consistent and professional across every piece.

Wide Range of Applications

The machine is suited for industries such as:

• Footwear production (especially fashion or safety shoes)

• Automotive upholstery (seat covers, dashboards)

• Leather goods (bags, belts, and saddles)

• Apparel (denim jackets, uniforms, outerwear)

• Home furnishings (leather sofas, cushions) Its adaptability makes it a go-to choice for manufacturers working with both flexible and tough fabrics.

Time, Labor, and Cost Efficiency

Save Time with Integrated Design

The machine features a streamlined and rigid frame with enhanced vibration dampening, enabling high-speed operation with minimal noise or instability. Operators benefit from intuitive controls and easy setup, reducing time spent adjusting fabric alignment or correcting skipped stitches.

Save Labor through Automation

Equipped with a direct drive motor and automated needle positioning, the machine eliminates the need for manual thread trimming or positioning adjustments. Optional features such as auto back-tacking, foot lift, and synchronized thread trimming allow a single operator to manage more complex tasks without fatigue or rework.

Save Material and Maintenance Costs

Due to its high stitch accuracy and feeding reliability, the Shibang 2530/2533/2534 reduces material waste caused by misaligned seams or re-stitched products. The rugged internal construction and long-life components cut down on downtime, replacement parts, and service needs—maximizing ROI for factories operating around the clock.

Fully Intelligent and Customizable

Programmable Stitching Parameters

The machine offers fully programmable stitching parameters via its control panel, allowing users to define stitch length, needle movement, and foot lift based on fabric type or design needs. This makes it ideal for short production runs or batch changes, with memory recall options to store multiple job presets.

Direct Drive and Energy Efficiency

Built with a servo direct drive system, the motor connects directly to the main shaft, eliminating transmission losses and reducing power consumption. This not only improves energy efficiency but also ensures faster acceleration, quieter operation, and smoother start-stop control, especially beneficial for precision herringbone seam placement.

Operator-Friendly Design

Ergonomic Layout

The arm and bed layout are optimized for easy fabric handling, while the needle and bobbin area are easily accessible for quick threading or maintenance. Optional LED lighting provides high visibility for precision stitching, especially with dark or multi-layered fabrics.

Digital Stitch Control

Electronic stitch control system ensures stitch-per-inch (SPI) uniformity across different material thicknesses. Whether working on leather car seats or padded shoe uppers, the herringbone stitch retains its visual quality and structural purpose.

Enhanced Cooling and Oil Circulation

The machine integrates an advanced lubrication system and fan-assisted cooling (in certain models) to maintain optimal internal temperatures during long production hours, preventing overheating and component wear.
