Abstract
Printing machine having at least one impression cylinder (16), characterised in that the impression cylinder (16) has a cylinder body (44) made of a material which, in circumferential direction of the impression cylinder (16) has a linear thermal expansion coefficient of less than 2×10−6 K−1. The material may be a composite material, for example, a material containing carbon fibers, in particular a synthetic resin reinforced with carbon fibers.
Claims20
Printing machine comprising:
- a central impression cylinder, the central impression cylinder having a cylinder body made of a material which, in a circumferential direction of the central impression cylinder, has a linear thermal expansion coefficient of less than 2×10−6 K−1;
- and
- a plurality of printing cylinders arranged at a periphery of the central impression cylinder.
Printing machine having at least one central impression cylinder, each central impression cylinder having a cylinder body made of a material which, in a circumferential direction of the central impression cylinder, has a linear thermal expansion coefficient of less than 2×10−6 K−1, and the central impression cylinder includes a part which radially supports the cylinder body from inside, and the part is made of a material which, in a radial direction, has a linear thermal expansion coefficient of less than 2×10−6 K−1.
Printing machine having at least one central impression cylinder, each central impression cylinder having a cylinder body as a cylindrical sleeve made of a material which, in a circumferential direction of the central impression cylinder, has a linear thermal expansion coefficient of less than 2×10−6 K−1, and the central impression cylinder includes a part which radially supports the cylinder body from inside, and the part is made of a material which, in a radial direction, has a linear thermal expansion coefficient of less than 2×10−6 K−1.
