The HX120DH Three-knife Trimmer is a high-performance three-side finishing machine specially designed for perfect-bound books and book blocks. It serves as an ideal trimming solution for post-binding finishing, featuring dual-purpose usability that supports both independent standalone operation and seamless inline connection with high-speed perfect binding production lines. With strong compatibility and stable mechanical performance, it fully meets flexible and large-volume book trimming demands in modern printing factories.
Delivering outstanding production efficiency, the machine runs steadily at a trimming speed of 4200 knives per hour for independent operation. When integrated into a complete perfect binding production line, it can synchronously support a comprehensive line speed of up to 12000 books per hour, perfectly matching high-speed continuous binding production and eliminating finishing bottlenecks in mass output.
Equipped with a professional belt conveyor system, the equipment precisely separates individual books and smoothly transports them to dual pre-stacking stations. The innovative multi-book stacking and batch cutting structure greatly improves single-cycle processing capacity, multiplying overall production efficiency compared with traditional single-piece trimming machines. It ensures consistent feeding positioning and stable cutting precision during high-speed continuous operation.
