Abstract
A three side trimmer is provided with a trimming table having a base, a first cutting stick fixed on the base opposed to a front edge trimming cutter in order to receive the knife edge of the front edge trimming cutter and, a table structure including a pair of elemental plates movable on the base along a direction parallel to the length of the first cutting stick. The first elemental plate of the table structure is provided with a second cutting stick arranged perpendicular to the first cutting stick in order to receive the knife edge of a top edge trimming cutter. The second elemental plate of the table structure is provided with a third cutting stick arranged perpendicular to the first cutting stick in order to receive the knife edge of a foot edge trimming cutter. The three side trimmer makes it possible to trim the three sides of the binding objects of different sizes without exchanging the trimming tables.
