The HX1800CTSO Center Saddle Thread Sewing and Outward Folding Machine is a professional integrated processing equipment dedicated to center saddle thread sewing and outward folding production. It is perfectly tailored for mass manufacturing of notebooks, passports, instruction manuals and hardcover book blocks, serving as a high-efficiency core finishing device for modern printing and bookbinding workshops.

Adopting a human-machine collaborative streamlined workflow, the machine only requires simple manual feeding, while all subsequent complex procedures are fully automated. Equipped with high-precision optical fiber sensor control, it realizes intelligent and accurate thread sewing, automatic thread cutting, standard outward folding with external pinholes, professional spine pressing and finished product delivery in one continuous cycle.

• Automated one-stop processing eliminates manual intervention
• Effectively unifies product standards and reduces human error
• Significantly reduces defective rates

Boasting powerful multi-block synchronous processing capability, this versatile machine can sew up to four book blocks at the same time within the processing range, greatly amplifying production capacity and optimizing batch production efficiency.

• Extremely precise stitching and neat outward folding effects
• Uniform pinhole position and flat book spines
• Consistent finished appearance for every product
• Fully meets high-standard commercial printing requirements

Supporting an ultra-wide adjustable production speed of 800 to 1800 books per hour, the equipment flexibly adapts to both medium and large-batch production tasks. It maintains stable high-speed operation without compromising processing accuracy, perfectly balancing high yield and superior product quality.

Strong product compatibility covers daily customized and standardized orders of various saddle-stitched and outward-folded publications.

Tailored for the special production requirements of passports, manuals and notebooks, the equipment achieves automated thread sewing and outward folding forming. Intelligent fiber optic sensor control ensures each sewing cycle is triggered accurately.

The finished book blocks feature outward pinholes, perfectly matching subsequent hardcover binding processes. Multi-block synchronous sewing capability significantly enhances production efficiency without sacrificing precision. Stable operation within 800-1800 books per hour provides a reliable automated solution for commercial printing and binding enterprises.
