Abstract: A printing sleeve includes a first and radially inward layer having an inner side for directly contacting the outer side of a printing cylinder, and an outer side which is radially opposite the inner side. The first and radially inward layer has a glass fiber reinforced compressible compound such that the glass fibers may absorb the forces that arise in the circumferential direction and/or in the longitudinal direction, and the compressible compound elements may absorb the pressures that arise in the radial direction. In this way, the materials which to date act separately in the base sleeve and the compressible layer are combined in one common layer in which said materials each may perform their function.

Abstract: The invention relates to a printing sleeve (1) comprising a first, radially inner layer (11) that has an inner side (11a) for making direct contact with the outer side of a printing cylinder (10), and an outer side (11b) which lies radially opposite said inner side (11a); as well as a second, radially outer layer (12) that has an outer side (12b) for forming a printing surface, and an inner side (12a) which lies radially opposite said outer side (12b). Said printing sleeve (1) is characterised in that the outer side (11b) of the first, radially inner layer (11) and the inner side (12a) of the second, radially outer layer (12) lie directly one against the other, and in that said first, radially inner layer (11) is designed to be able to absorb both forces occurring in the circumferential direction (U) and/or longitudinal direction (L), and pressures that arise in the radial direction (R).

Abstract: The invention relates to a multilayer sheet material (20) in the form of a printing blanket having a printing layer (21) made of a polymer material, at least one compressible layer (22, 23) and at least one reinforcing base layer (24, 25), the individual layers forming a bond with each other, characterized in that the printing layer (21) has an additional coating (27) locally bounded at at least one location of the printing layer (21) and completely preventing ink transfer at the locally bounded location, wherein the additional coating (27) is built up of at least one resin and/or at least one paint and/or at least one polymer. The invention further relates to a method for making such a multilayer sheet material (20).

Abstract: The invention is directed to a multiple-layer flat structure (1) in the form of a printing blanket or a printing plate for flexographic and letterpress printing with: a printing layer (2) which is made from a polymeric material and is provided with laser engraving; at least one compressible layer (3); and, at least one strength-support layer (4); wherein the individual layers form an adhesive connection among one another. The multiple-layer flat structure (1) according to the invention is distinguished by the fact that the polymeric material of the printing layer (2) is a vulcanizate. Advantageous materials are proposed in this regard. The printing layer (2) expediently lies directly on a compressible layer (3). The compressible layer (3) is in turn in direct contact with a strength-support layer (4).

Abstract: The invention relates to a printing blanket assembly for a blanket cylinder of a rotary printing press. The printing blanket assembly comprises a dimensionally stable support plate (02, 18) with two ends, one of which is the forward end and the other one is the trailing end with respect to the rotation of the blanket cylinder, these ends being fastened to the blanket cylinder with folded, printing-blanket free limbs (21, 22). The assembly further comprises a printing blanket (03, 19), fastened to the outside of the support plate (02, 18) and having a forward end (12, 31) and a trailing end (11, 32). Said printing blanket assembly allows for perfect printing also in the area of a gap between the limbs (21, 22) and can be produced in a simple manner.

Abstract: Rubber blanket sleeve for a channel-free rubber blanket cylinder of an offset printing machine and process of producing rubber blanket sleeve. The rubber blanket sleeve includes an inner, dimensionally stable support sleeve arranged as a supporting layer, and a microporous compressible elastomer layer having a compressibility within a range between about 7% and 15% with a load of 100 N/cm2. The elastomer layer includes a rubber matrix having a tensile stress of greater than about 2.2 N/mm2 and less than about 15 N/mm2 with 100% elongation. An outer covering rubber layer is arranged as a printing layer. All of the layers are composed of seamless, cylindrical bodies and are coupled to one another. The process includes arranging an inner, dimensionally stable support sleeve as a supporting layer, and positioning a microporous compressible elastomer layer having a compressibility within a range between about 7% and 15% with a load of 100 N/cm2 over the support sleeve.

Abstract: Printing web for utilization on printing cylinders and process of producing printing web. Printing web includes an internal carrying layer arranged to face the printing cylinder during use of the printing web. The internal carrying layer includes a flexible metal sheet which is adaptable to a curvature of the printing cylinder and which is coupled to an adjacent layer via a bonding agent. The printing web also includes a microporous compressible intermediate layer, and an exterior printing layer.
