Disclosed is a method for binding a bundle of leaves, of which a strip of each of the leaves is folded separately beforehand along a first line to form a first fold line that extends parallel to and at a first distance from the edge, and subsequently is folded again along a second line to form a second fold line that extends parallel to and at a second distance from the edge whereby the first distance is different from the second distance.

A method for binding a bundle (6) of leaves (1), where an edge (3) of the bundle (5) of leaves (1) is bound, and for the binding, use is made of a bundle (6) of leaves (1) in which the leaves (1) present a first fold line (2) that extends parallel to and at a distance (A) from the edge (3), and where the leaves (1) also present a second fold line (4) that is located parallel to and at a distance (B) from the first fold line (2), and which is located between the edge (3) and the first fold line (2).

It is an object to provide a trimmer that can trim a fore-edge portion of a bound material except a cover and that can be excellent in productivity and cost. A cover has flap portions adjacent to the fore-edge portion of the bound material, a trimmer includes: a trim cutter that trims the bound material; a blade receiving portion that receives an edge of the trim cutter; a base portion and a pressure portion that nip and position the bound material; and a pair of guide portions arranged for movement in a direction close to or away from the bound material, wherein the guide portions are inserted between the book block and the cover so as to peel the cover together with the flap portions up when the fore-edge portion of the bound material is trimmed by the trim cutter.
