Product Description
Product Selling Points
- Large Format Versatility: large size book binding machine accommodates books from 150100mm to 520460mm (A3/A4+ sizes), supporting thick publications, catalogs, and hardcover book blocks that standard machines can’t handle.
- Blazing Sewing Speed: 50 cycles per minute (3,000 cycles per hour) – outperforms entry-level semi-automatic machines (20-30 cycles/min) to cut production time for bulk orders.
- Stable & Quiet Performance: Frequency conversion speed control eliminates sudden speed fluctuations; low operating noise (<60dB) creates a comfortable workshop environment.
- Enhanced Safety Features: Infrared safety protection + physical safety cover – automatically stops operation if hands approach the sewing area, reducing accident risks.
- Precise & Durable Binding: 13 needle groups with 18mm uniform spacing – creates tight, tear-resistant thread bindings that outlast glued or spiral bindings for long-life books.

- Feeding Mechanism: Semi-automatic feeding with alignment guides – keeps paper stacks straight during sewing, avoiding misalignment or skipped stitches.
- Safety Components: Infrared sensor + full-wrap safety cover – triggers emergency stop if foreign objects enter the sewing zone; complies with global safety standards.
- Structural Design: 150013001500mm footprint fits industrial workshops; 800kg stable build reduces vibration during high-speed operation.
- Power Efficiency: 0.55KW low power consumption – balances performance and energy savings for 24/7 continuous use.
Product Comparison
vs. Manual Book Sewing: Manual sewing takes 5-10 minutes per book (6-12 books/h) with inconsistent stitching; our machine completes 50 cycles/min, producing 100+ books/h with uniform quality – saves 90% labor time.
vs. Standard Semi-Automatic Machines: Most standard models have 8-10 needle groups and max 30 cycles/min; our 13 needle groups + 50 cycles/min design delivers stronger bindings and 67% faster output, plus larger format compatibility.
