Apparatus and method for a printing-press cylinder sleeve
View Patent ↗A sleeve, in particular a rubber-blanket sleeve, for a printing press is disclosed. The sleeve having a construction which has at least two layers, having an inner layer which is configured as a carrier layer and an outer layer which is configured as a covering layer and serves for pressure transfer, the sleeve having a hollow-cylindrical design with a cylindrical inner surface and a cylindrical outer surface. The inner layer which is configured as a carrier layer is convexly or concavely curved on the radially outer side, a layer which adjoins the carrier layer having a curvature on a radially inner side which is complementary to the curvature of the radially outer side of the carrier layer.
1. A sleeve, in particular a rubber-blanket sleeve, for a printing press, comprising an inner layer which is configured as a carrier layer and an outer layer which is configured as a covering layer and serves for pressure transfer, the sleeve having a hollow-cylindrical design with a cylindrical inner surface and a cylindrical outer surface, wherein the inner layer which is configured as the carrier layer has a curvature that is concavely curved on a radially outer side, and wherein the outer layer which is configured as the covering layer adjoins the carrier layer and has a curvature on a radially inner side that is convexly curved and is complementary to the curvature of the radially outer side of the carrier layer;
wherein the radially outer side of the carrier layer adjoins the radially inner side of the covering layer and wherein a radially inner side of the carrier layer forms the cylindrical inner surface of the sleeve and a radially outer side of the covering layer forms the cylindrical outer surface of the sleeve.
2. The sleeve according to claim 1 , wherein the carrier layer is configured as an incompressible layer and the covering layer is configured as a compressible layer.
3. The sleeve according to claim 1 , wherein the carrier layer is configured as a metal layer and the covering layer is configured as a rubber layer.
4. A sleeve for a printing press, comprising:
a first layer; and
a second layer;
wherein the first layer has a curvature that is concavely curved on a radially outer side and wherein the second layer adjoins the first layer and has a curvature on a radially inner side that is convexly curved and is complementary to the curvature of the radially outer side of the first layer;
and wherein the radially outer side of the first layer adjoins the radially inner side of the second layer and wherein a radially inner side of the first layer forms a cylindrical inner surface of the sleeve and a radially outer side of the second layer forms a cylindrical outer surface of the sleeve.
