1 is a schematic side view of an embodiment of a printing unit of a rotary printing press according to the present invention. A furnisher that includes a plate cylinder 1, an impression cylinder 3 that presses a printing substrate 5 against the plate cylinder 1, and a nozzle-type ink supply device 6 that supplies ink 7, and that supplies ink to the plate surface of the plate cylinder 1. The furnisher roll is provided with a roll 2 and has grooves formed with cylindrical portions at both ends thereof. FIG. 1B is a schematic side view showing a plate cylinder and a furnisher roll in contact with the plate cylinder in the rotary printing press of the present invention. Furnisher roll 2
Is provided at each end with a cylindrical portion 10 having a diameter smaller than the outer diameter of the roll, that is, a groove extending in the circumferential direction is formed between the edge portions 10a and 10b on both sides of the cylindrical portion 10. ing. The position of the cylindrical portion 10 is shown in FIG.
As shown in (b), it is set at a position facing the edge of the plate surface 1a of the plate cylinder 1. More specifically, between the edge portions 10a and 10b on both sides of the cylindrical portion 10,
As shown in FIG.
As shown in (c), the position of the cylindrical portion 11 is the edge portion 1.
1b and the edge portion 1b of the printing plate are positioned so as to coincide with each other. In other words, the edge portion 10a or 11a of the cylindrical portion 10 or 11 on the side of the center of the finisher roll is connected to the printing plate 1a.
, But the other edge portion 10b or 11b is determined so as not to contact the plate surface.

しい。When the furnisher roll 2 having the above structure is used, the end of the contact portion between the surface of the furnisher roll and the plate surface of the plate cylinder is connected to the edge 10a of the cylindrical portion 10 or 11 of the finisher roll 2. Or 11a, from which ink is collected from the plate in each groove between the edge portions 10a, 10b or 11a, 11b on both sides of the cylindrical portion 10 or 11. For this reason, scattering of the ink to the side of the plate cylinder and the finisher roll is prevented. Here, the distance between the edge portions 10a and 1b and the edge portions 11a and 1b is about 1
It is desirable to set it to about 0 mm. The circumferentially extending groove formed by the plate surface of the plate cylinder 1 and the cylindrical portions provided at both ends of the furnisher roll is preferably about 5 mm.
