  • TRILATERAL CUTTER PARTICULARLY FOR TRIMMING THE EDGES OF BOOKS WITH A SIMPLIFIED BLADE CHANGE
    Publication number: 20020148339
    Abstract: To simplify and reduce the necessary time of blade changing (4-6), every blade is attached to the connecting rods (15) which drive said blade without the interposition of a blade-holder. The setting of the cutting force with which each blade (4-6) presses on the counter-blade (7-9) is fixed by calibrating a maximum pressure hydraulic valve (30). In this way the cutting force exerted by each blade (4-6) does not exceed the optimal predefined maximum value for cutting all the sheets of paper, without damaging the counter-blades (7-9.
