Upon request, the three-knife trimmer allows producing books with gate-folded covers in one pass. Vacuum heads open the cover upwards and downwards outside the cutting area to allow the trimming of the front. The system is activated via a control panel or completely automated via barcode allowing maximum production efficiency.


Trimming features, upon request, silicon spray pads for layflat photo books. The system applies silicon on the entire length of the knives allowing to process books glued back-to-back.
