ABSTRACT:
Gap guards are attached to a notch of an impression cylinder in such a manner as to allow grippers to project from inside the notch, and have respective guide surfaces. The guide surfaces extend between a circumferentially first end portion and a second end portion of the notch and have a curvature substantially equal to that of the outer circumferential surface of the impression cylinder. The guide surfaces are flush with the outer circumferential surface of the impression cylinder at the second end portion, whereas a clearance is formed between the guide surfaces and the outer circumferential surface of the impression cylinder at the first end portion. Grippers have respective guide surfaces. The guide surfaces have a curvature substantially equal to that of the outer circumferential surface of the impression cylinder such that the guide surfaces are flush with the outer circumferential surface of the impression cylinder at the first end portion.
