Abstract:
1. A printing press, comprising: a printing unit which performs printing on a sheet; a machining unit which performs a machining process for the sheet; first driving means for driving the printing unit; second driving means for driving the machining unit; controlling means for controlling the first and second driving means to synchronize the drives of the printing unit and the machining unit with each other; a first cylinder driven by the first driving means and having a plurality of first recesses, each first recess accommodating, therein, first sheet holding means for holding the sheet; and a second cylinder driven by the second driving means and having a plurality of second recesses, each second recess accommodating, therein, second sheet holding means for receiving the sheet from the first sheet holding means of the first cylinder and for holding the sheet, wherein the controlling means control phases and speeds of the first cylinder and the second cylinder, such that the sheet is transferred from the first sheet holding means to the second sheet holding means, wherein, the first cylinder supports a plurality of first sheet holding means provided in the printing unit in a direction perpendicular to a transporting direction of the sheet, and has a plurality of first notched portions provided on a first circumferential surface of thereof, to which the second sheet holding means oppose, the first circumferential surface supporting the sheet; and a plurality of second sheet holding means are provided in the machining unit while deviating phases thereof from phases of the first sheet holding means in the direction perpendicular to the transporting direction of the sheet, and has a plurality of second notched portions provided on a second circumferential surface thereof, to which the first sheet holding means oppose, the second circumferential surface supporting the sheet, wherein the plurality of first recesses extends along an axial direction of the first cylinder and the plurality of first notched portions extends along a circumferential direction of the first cylinder perpendicular to the axial direction of the first cylinder, such that the plurality of first notched portions and portions of the first circumferential surface are provided alternately with respect to the axial direction of the first cylinder, and the plurality of first notched portions, in conjunction with the plurality of first recesses, forms a plurality of grooves, each groove extending along an entire circumference of the first cylinder, and the plurality of second recesses extends along an axial direction of the second cylinder and the plurality of second notched portions extends in a circumferential direction of the second cylinder perpendicular to the axial direction of the second cylinder, such that the plurality of second notched portions and portions of the second circumferential surface are provided alternately with respect to the axial direction of the second cylinder, and the plurality of second notched portions, in conjunction with the plurality of second recesses, forms a plurality of grooves, each groove extending along an entire circumference of the second cylinder.
