Document Type and Number:
Japanese Patent JP4494577
Kind Code:
B2
Abstract:
A paper guide apparatus of a perfecting press is disclosed. The perfecting press comprises a blanketed impression cylinder (2) which has a holding device for holding paper (20) and prints one side of the paper (20), and a blanket cylinder (3) which is in contact with the blanketed impression cylinder (2) and prints the other side of the paper (20). The blanketed impression cylinder (2) and the blanket cylinder (3) are arranged nearly horizontally. In the paper guide apparatus, suction chambers (23a to 23c) for sucking and guiding the paper (20) transported by the blanketed impression cylinder (2) are provided between a transfer cylinder (15) located directly ahead of the blanketed impression cylinder (2) and the blanket cylinder (3), and an air nozzle (21) is provided for blowing air between the paper (20) transferred from the transfer cylinder (15) to the blanketed impression cylinder (2) and the circumferential surface of the blanketed impression cylinder (2). The paper guide apparatus can prevent a printing trouble, such as doubling or smudging, due to a touch of the paper to the circumferential surface of the cylinder before a printing pressure is applied.
