HDP TST Digital Three Side Trimmer

The HDP TST Digital Three-Side Trimmer is engineered for digital book finishing and uses advanced single-knife trimming technology with automatic pile rotation to deliver precise, mark-free cutting for perfect-bound books, sewn book blocks, board books, and similar products. Its robust construction and automated workflow provide reliable trimming performance for short-run, variable-format, and on-demand production. The machine features zero-makeready operation, enabling instant format changes through barcode scanning or JDF workflow integration. A servo-controlled hydraulic clamping system automatically adjusts to different book thicknesses, helping maintain stable positioning and consistent trimming quality throughout variable production jobs. A unique bi-directional knife movement helps prevent tearing at the book spine while ensuring clean and accurate trimming results. Optional corner rounding further expands finishing capability, while the fully interlocked safety system supports unattended operation. Combining zero-makeready automation, variable-thickness adjustment, intelligent workflow integration, and precise single-knife trimming, the HDP TST provides a flexible and efficient digital three-side trimming solution for professional book production.
