| 摘要 |
The invention relates to an apparatus for measuring the radial distance between plate or rubber web (27) on a plate cylinder or rubber cylinder (25), respectively, of an offset printing press and a cylindrical reference surface (28) at an end surface of the cylinder. The apparatus comprises a V-shaped measuring body (1) applied to the rubber web (27) with elongated rolls (5, 6) journalled on the measuring body and in contact with the web. A support plate (18) protruding from one end of the measuring body is mounted detachable and supports a measuring gauge (21) provided with a measuring point (22) applied to the cylindrical reference surface (28), which support plate (18) preferably has a shortest length from the measuring gauge (21) to the nearest end surface of the rolls (5) prescribed by the construction of the offset printing press. |
