Abstract

A top edge trimming cutter, a bottom edge trimming cutter and a front edge trimming cutter are arranged to have predetermined distances from one another so as not to cause mechanical interference. The top edge trimming cutter, a first table element, a first blade receiving plate and a first pressing plate pressing a bound material against the first table element are attached to a first frame element. The bottom edge trimming cutter, a second table element, a second blade receiving plate and a second pressing plate pressing the bound material against the second table element are attached to a second frame element. Relative movement of the first and second frame elements effects relative movement of the top edge trimming cutter and the bottom edge trimming cutter, relative movement of corresponding first and second blade receiving plates and relative movement of corresponding first and second pressing plates.
