HD-HD 143 Three-Knife Trimmer

The HD-HD 143 three-knife trimmer with Bookjet® system trims book blocks and brochures on three sides in separate trimming cells (front trimmer and head/foot trimmer). The system can be used as individual unit or in a production line. Thanks to its dynamic adjustment axes the machine continuously adjusts to changing product sizes (with no changeover processes or the need for interchangeable parts).

Dynamic Adjustment Axes

Blocks with different thicknesses but the same size are measured by the infeed roller. In order to adjust the axes (block thickness, length and width), all product-related data is taken from the job list using code match during the infeed process.

Easy to operate

The machine changes over fully automatically with no need for intervention by the machine operator.
