HX325 Four Side Trimmer

The HX325 Four-Side Trimmer is designed for precise trimming of all four edges of book blocks, paper stacks, or boards in a single cycle or continuous inline workflow. Unlike conventional three-knife trimmers, it completely trims all four sides to produce clean, loose-leaf stacks, making it an essential pre-processing solution for wire-o notebooks, board books, hardcover albums, premium cards, and similar products. Equipped with servo-driven systems and PLC control, the HX325 provides accurate, stable, and efficient trimming while supporting seamless integration with upstream gathering or binding equipment and downstream stacking systems. A heavy-duty clamping mechanism ensures reliable product positioning during cutting, helping maintain consistent trimming quality across different formats and materials. The touchscreen supports one-touch make-ready for fast and convenient job changeovers, while an optional corner-rounding module further expands finishing capability. Combining four-side trimming, automated control, inline integration, strong clamping, and optional corner rounding, the HX325 provides a flexible and efficient finishing solution for professional bookbinding, notebook, board book, and premium card production.
