Abstract:
1. A covering device for rotating parts, comprising: a first rotating part supported rotatably; a second rotating part opposing said first rotating part and supported rotatably; and a covering member, located in a vicinity of said first rotating part and said second rotating part, for covering at least a spacing between said first rotating part and said second rotating part, said covering member being provided with an opening, wherein said covering member is a safety bar for preventing a wrap-in in a printing press, and wherein said opening is a hole provided in said safety bar, such that air engulfed from a clearance between the safety bar and a first circumferential surface of the first rotating part and from a clearance between the safety bar and a second circumferential surface of the second rotating part into a region defined by the first circumferential surface, the second circumferential surface, and the safety bar by rotation of the first rotating part and the second rotating part, is released outside the region through the hole, wherein said covering member is provided in a range surrounded by a facing area where said first rotating part and said second rotating part are opposed to each other, a first outer peripheral surface of said first rotating part upstream of said facing area in a direction of rotation of said first rotating part, a second outer peripheral surface of said second rotating part upstream of said facing area in a direction of rotation of said second rotating part, and a plane in contact with said first outer peripheral surface and said second outer peripheral surface.
