Abstract

A trimmer trims a bound material at end portions and/or corner portions of the bound material. The trimmer has a table (2), a pressing unit (4), a trimming mechanism (5) that has a trimming blade (52) and moves the trimming blade (52) to the trimming position, a rotation mechanism (3) that rotates the table (2), a rotation control unit that is operatively connected to the rotation mechanism (3) in such a way that a predetermined trimming line of the bound material positioned parallel to a longitudinal direction of the trimming blade (52), a moving mechanism (6) that moves the trimming mechanism (5) in a direction perpendicular to the longitudinal direction of the trimming blade (52), and a movement control unit that is operatively connected to the moving mechanism (6) so as to move the trimming mechanism and align the trimming line and the trimming position with each other.

Dependent claims

A trimmer for trimming a bound material, including:

a table on which the bound material is to be placed;
a pressing unit fixing the bound material on the table;
a trimming mechanism having a trimming blade and moving the trimming blade between a trimming position and a non-trimming position so as to trim an edge portion and/or a corner portion of the bound material;
a rotation mechanism rotating the table;
a rotation control unit operatively connected to the rotation mechanism so as to rotate the table in such a way that a predetermined trimming line is positioned parallel to a longitudinal direction of the trimming blade, the predetermined trimming line being set for the edge portion and/or the corner portion of the bound material;
a moving mechanism moving the table or the trimming mechanism in a direction perpendicular to the longitudinal direction of the trimming blade;
and
a movement control unit operatively connected to the moving mechanism so as to move the table or the trimming mechanism in such a way that the trimming line and the trimming position are aligned with each other.

A method for trimming a bound material, including:

(a) providing a trimmer for trimming the bound material;
the trimmer including
a table on which the bound material is placed,
a pressing unit fixing the bound material on the table,
a trimming mechanism having a trimming blade and moving the trimming blade between a trimming position and a non-trimming position so as to trim the bound material along a trimming line of the bound material,
