Claims
- 1. A cylinder for receiving a printing form, the cylinder being formed with a gap projecting into an interior of the cylinder and having gap edges, the gap extending in a direction of generatrices of the cylinder and serving for guiding ends of a printing form therethrough, comprising a device for tautening the printing form on a jacket surface of the cylinder, at least one of the gap edges having a curvature for attaining tensioning forces which are constant over at least approximately an entire width of the printing form.
- 2. The cylinder according to claim 1, wherein said curvature, in the circumferential direction of the cylinder, projects in the region of the center of the printing form and recedes in side regions of the printing form.
- 3. The cylinder according to claim 1, wherein said tautening device acts at both ends of the printing form, both of the gap edges having a cambered form, the distance between the gap edges being spaced apart a distance which is reduced in the region of the center of the printing form, and increases continuously towards side regions of the printing form.
- 4. The cylinder according to claim 1, wherein the gap edges are rounded.
- 5. The cylinder according to claim 1, wherein the gap edges have a low coefficient of friction.
- 6. The cylinder according to claim 5, including roller elements for at least partly carrying the printing form, said roller elements serving for reducing the friction along the curved gap edges.
