HX325 Four Side Trimmer Precision Cuts All Four Edges in One Cycle for Wire-O Notebooks Board Books and Paper Stacks

Beyond Three-Knife Trimming – The Need for Four-Side Cutting
Three-knife trimmers are standard for trimming head, foot, and face of bound books. However, many products require complete removal of all four edges – such as wire‑o notebooks, board books, loose‑leaf stacks, and premium cards. Conventional methods involve multiple passes or separate machines, leading to alignment errors and reduced productivity. The HX325 Four Side Trimmer is purpose‑built for these applications. It precisely trims all four edges of book blocks, paper stacks, or boards in a single cycle or inline workflow – delivering finished, ready‑to‑use stacks in one operation.

HX325 Four Side Trimmer

Essential Pre‑Process for Wire‑O Notebooks, Board Books, and More
Unlike three‑knife trimmers that leave one edge intact, the HX325 completely removes all four sides to produce loose‑leaf stacks – the essential pre‑process for:

• Wire‑O notebooks – clean, uniform edges for coil binding

• Board books – flush, smooth edges for children's books

• Hardcover albums – precise trimming for photo books and portfolios

• Premium cards – all‑four‑sides trimmed for professional decks

This capability makes the HX325 an indispensable finishing tool for manufacturers producing products that require fully trimmed, loose‑leaf sheets before binding or packaging.

Servo Drives and PLC Control for Seamless Integration
The HX325 is powered by servo drives and PLC control systems that ensure precise, repeatable trimming across thousands of cycles. The servo system delivers accurate positioning and consistent cutting force, while the PLC manages the entire trimming sequence – including infeed, clamping, cutting, and delivery. This control architecture also allows the HX325 to seamlessly integrate with upstream gatherers and binders (for inline workflow) or downstream stackers (for offline batch processing). The result is a flexible trimming solution that adapts to both standalone and fully automated production lines.

Heavy‑Duty Clamping, One‑Touch Touchscreen Makeready, and Optional Corner Rounding
The HX325 is built for precision and ease of use. A heavy‑duty clamping mechanism securely holds stacks from 5mm to 50mm thick during the cutting cycle, preventing shifting and ensuring consistent edge quality across all layers. One‑touch touchscreen makeready simplifies job changeovers – operators select the product size, and the machine automatically adjusts to the correct cutting positions. For applications requiring rounded corners, an optional corner‑rounding module is available, enabling the HX325 to deliver fully finished products – all four sides trimmed, corners rounded – in a single pass.

High‑Speed, High‑Precision Trimming for Demanding Production
For book manufacturers, notebook producers, and print finishers that need precise four‑side trimming at production speed, the HX325 Four Side Trimmer delivers exceptional performance. It handles infeed sizes from 132×146mm to 325×325mm and delivers finished stacks from 114×130mm to 310×310mm, with a thickness range of 5‑50mm. Operating at 15‑20 cuts per minute, the HX325 keeps pace with high‑volume binding lines. Servo drives and PLC control ensure repeatable accuracy. Heavy‑duty clamping and optional corner rounding provide complete finishing in one cycle. Upgrade from multiple trimming passes to the HX325 – and trim all four sides, perfectly, in one pass.
