摘要:
A damping unit for a press has means for applying a clamping solution to a printing form and means for setting the quantity of damping solution applied. At least one sensor is provided for registering the quantity of damping solution actually applied to the printing form. By means of a comparison with a predefined quantity of damping solution, the quantity of damping solution on the printing form can be regulated.

A rubber sleeve for a printing press and a method for producing a rubber sleeve is disclosed. The rubber sleeve has a rigid support sleeve and a blanket that is wrapped around the support sleeve as well as is firmly connected to the support sleeve. The blanket has at least a two-layer structure with an inner layer embodied as a base layer and an outer layer serving as a functional layer for the printing process, where the butting edges of the blanket are connected to one another via a sealing material, which is introduced in a gap embodied between the butting edges. The sealing material is introduced in the gap embodied between the butting edges while forming a channel.

A transfer plate, particularly a blanket plate, for a transfer cylinder, with a plate-like support, where a blanket being used for ink transfer is applied to a first side of the plate-like support, and where a film is applied to a second side of the plate-like support that is opposite from the first side, via which film a packing height of the transfer plate on a transfer cylinder can be predetermined. The film is applied to the second side of the plate-like support in such a way that a surface of the support covered by the film on the second side is smaller than a surface of the support covered by the blanket on the first side.

A printing couple of a printing press, such as a rotary printing press, where the printing couple includes a form cylinder, a transfer cylinder, an impression cylinder, and an inking couple. Here, the inking couple can apply the printing ink to the form cylinder, that is, to the printing forms which are positioned on the form cylinder. The transfer cylinder, which carries at least one blanket or rubber sleeve positioned on it, transfers the printing ink to a substrate. The ink is transported through a printing gap formed between the transfer cylinder and the impression cylinder. The diameter of at least one cylinder, such the form cylinder, the transfer cylinder and the impression cylinder, is graduated in the axial direction.

A printing blanket comprising a rigid carrier plate on which an elastic layer is arranged is provided. The elastic covering layer has a surface that can be inked and by which a printing image can be transferred onto a printing material. An end of the carrier plate is not covered by the elastic covering layer, and an end of the elastic covering layer is covered by a sealant. The sealant covered end of the elastic covering layer has a sealing geometry that provides a greater surface area to which the sealant can adhere than a smooth flat surface at the end of the elastic covering layer.

A rubber blanket for covering a transfer cylinder of a printing machine is provided. The transfer cylinder includes a cylinder channel for receiving an end of the rubber blanket to secure the rubber blanket to the transfer cylinder. The rubber blanket includes a rigid carrier plate and a plurality of layers that are arranged on the carrier plate. The plurality of layers include a cover layer, a non-expandable layer arranged underneath the cover layer and at least one other layer. A first end portion of the rubber blanket is adapted for insertion into a cylinder channel. The cover layer and the non-expandable layer extend into the first end portion and the at least one other layer does not extend into the first end portion such that when the rubber blanket is secured to a transfer cylinder the cover layer and the non-expandable layer are inserted into the cylinder channel and the at least one other layer is not inserted into the cylinder channel.

A printing blanket for fastening on a printing blanket cylinder and a method for the production thereof are disclosed. The printing blanket includes at least one inner carrier layer, a first intermediate layer designed as a woven fabric layer and an outer cover layer. The woven fabric layer includes warp threads and weft threads. The printing blanket can be fastened on a printing blanket cylinder such that the warp threads extend in the axial direction of the printing blanket cylinder and the weft threads extend in the circumferential direction of the printing blanket cylinder.

摘要:
A printing unit of a rotary printing press with a transfer cylinder and a form cylinder interacting with the transfer cylinder is disclosed. The body length of the transfer cylinder and the form cylinder corresponds to six horizontal or upright print pages and the transfer cylinder has two channels offset by 180° in the circumferential direction to accommodate printing blankets. Two or three printing blankets are arranged next to one another in the longitudinal direction of the transfer cylinder. With the arrangement of two printing blankets, one printing blanket is twice as wide as the second printing blanket and the printing blankets each are attached in one of the two channels offset by 180°. With the arrangement of three printing blankets, two adjacent printing blankets are attached in a channel and the third printing blanket is attached in the offset channel.
